Effect of dried guduchi (Tinospora cordifolia) leaf powder on rheological,organoleptic and nutritional characteristics of cookies

Tinospora cordifolia (Guduchi) is a shrub with various medicinal properties like, antioxidant, anti-diabetic, anti-inflammatory, antihepatotoxic, etc., and widely used in Ayurvedic preparations. Use of dried Tinospora leaf powder (DTLP) at the levels of 2.5, 5.0 and 7.5% on the rheological characteristics of wheat flour; organoleptic and nutritional characteristics of cookies was studied. Incorporation of increasing amount of DTLP from 0 to 7.5% increased farinograph water absorption, decreased dough stability; increased amylograph gelatinization temperature, decreased peak viscosity; increased hardness, decreased cohesiveness and springiness of cookie dough; decreased spread ratio and increased breaking strength of the cookies. Sensory evaluation showed that cookies incorporated with 5% DTLP were acceptable. Addition of DTLP increased the protein, dietary fiber, iron, calcium, radical scavenging activity and β-carotene contents of the cookies. The results showed the possibility of utilizing DTLP to improve the nutritional properties of cookies.     

Drivers of plant-based convenience foods consumption: Results of a multicomponent extension of the theory of planned behaviour

Current lifestyles always pose increasing time pressure that can result in unhealthy diets. Our study addresses the role that high-quality plant-based convenience foods can play in promoting healthier consumptions. While convenience foods are in fact often associated with poor nutritional values, the spread of healthy convenience foods could respond to the needs of new lifestyles and promote better food choices. The study is based on a multicomponent model of the Theory of Planned Behaviour that has made it possible to verify how control factors such as cooking skills, product availability, budget, time pressure, and interest in healthy eating can affect the consumption of precooked plant-based foods. The results of Structural Equation Models applied to a sample representative of the Italian population (600 individuals) highlight the presence of a consistent group of consumers (almost 70%) that consider plant-based convenience foods as a useful means to improve their diet. For this cluster, the control factors that significantly influence behaviour are market availability, interest in healthy eating, and time pressure. The advancements in knowledge that this research produces are translated into guidelines for producers, retailers, and policy makers that, in synergy, might encourage consumers to replace unhealthy foods with healthy ones.     

Precooked bran-enriched wheat flour using extrusion: dietary fiber profile and sensory characteristics

ABSTRACT:  The effect of precooking by extrusion processing on the dietary fiber profile of wheat flour substituted with 0%, 10%, 20%, and 30% wheat bran was evaluated. Depending on the level of bran, total dietary fiber (TDF) and soluble dietary fiber (SDF) in uncooked flours ranged from 4.2% to 17.2% and 1.5% to 2.4%, respectively. Precooking by extrusion significantly increased SDF in flours (by 22% to 73%); although in most cases it also led to a significant decrease in TDF. Cookies and tortillas produced from uncooked and precooked flours with 0% and 20% substituted bran were evaluated for consumer acceptability using a 9-point hedonic scale. With a few exceptions, all cookies had scores ranging from 6 to 7 ("like slightly" to "like moderately") for each attribute, including overall acceptability, appearance, texture, crumbliness, and flavor. Tortillas were rated for the same attributes except for crumbliness, which was replaced with chewiness. In most cases, tortilla scores ranged from 5 to 7 ("neither like nor dislike" to "like moderately"). Consumer acceptability scores of cookies from uncooked flour did not change significantly with increase in bran substitution from 0% to 20%. However, consumer scores for tortillas did decrease significantly with increase in bran level. Extrusion precooking of the flours did not improve the consumer acceptability of cookies and tortillas; however, it did improve their dietary fiber profile by increasing the SDF significantly.     

EFFECTS OF AVOCADO FRUIT PUREE AND OATRIM AS FAT REPLACERS ON THE PHYSICAL, TEXTURAL AND SENSORY PROPERTIES OF OATMEAL COOKIES

ABSTRACT

This study was conducted to investigate the effectiveness of partial replacement (50% level) of butter fat by two different fat replacers (avocado puree and Oatrim) on the physical, textural and sensory properties of oatmeal cookies. Compared with the control cookie, both fat‐reduced cookies had greater heights, reduced spreads, increased % moisture loss and higher water activities (P < 0.05). Textural measurements made using the TA.XT Plus Texture Analyzer showed the fat‐reduced cookies to be tougher and less brittle (P < 0.05). Appearance was the only sensory category in which a significant difference was seen (P < 0.05). Both avocado and Oatrim cookies were found to be overall acceptable, and at the 50% level of fat replacement, the total fat content for the avocado and Oatrim cookies decreased by 35 and 39%, respectively.

PRACTICAL APPLICATIONS

When incorporated into an overall healthy diet, reduced‐fat foods made with fat replacers can play an important role in helping consumers reach and maintain their goal of reducing consumption of dietary fat. Results from this study indicate that cookies with acceptable physical, textural and sensory properties could be produced when 50% of the fat is replaced by Oatrim and avocado fat replacers. Dietitians should be aware of such fat replacers. Improved nutritional content, acceptability, ease of preparation and low cost make avocado puree a viable fat replacement option for use in home‐baked products. This data can also serve as a resource to further explore the utilization of Oatrim in developing commercially prepared low‐fat cookies and other baked products.

     

Associations between nutritional properties of food and consumer perceptions related to weight management

Consumer perceptions of food (for example, how filling or healthy) influence eating behaviour and appetite control. Therefore approaches to understand the global nutritional attributes of foods that predict the strength of consumer perceptions are of academic and commercial interest. The current research describes the development of a flexible platform for systematically mapping the global nutritional attributes of foods (both objective and perceived) to consumer perceptions of those foods. The platform consists of a database of standardised UK food images (currently n = 300), linked to a catalogue of detailed perceptual, nutritional, sensory, cost, and psychological information (‘nutritional attributes’). The platform also incorporates demographic and psychometric questionnaires to examine the importance of nutritional attributes on consumer perceptions within or between relevant target groups. In the current study, the platform was applied to a sample of dieting and non-dieting British men and women (n = 887) to examine the global attributes of a subset of foods (n = 75) and their association with successful weight management (i.e. supportive of weight loss, weight loss maintenance or prevention of weight gain). Generalised linear models identified energy density, cost (£/kcal), perceived energy content and satiating capacity as the main nutritional attributes underlying dieters’ and non-dieters’ perception of successful weight management food. Additionally, pleasantness, and desire not to (over) eat were uniquely associated with dieters’ perception of food as good for weight management; pleasantness was positively associated with weight management and desire to eat was negatively associated with weight management. Therefore, global nutritional attributes of foods can predict and distinguish the extent consumers’ perceive a food to be related to successful weight management. This platform will be extended to increase the variety of foods and specificity of nutritional attributes in the database suitable for a range of commercial, academic or clinical research applications.     

CONSUMER EVALUATION OF SOY INGREDIENT–CONTAINING COOKIES

Abstract The objective of this study was to evaluate consumer acceptability of cookies prepared using four different soy ingredients including two types of extruded and expelled soy flours (INTSOY and Insta–Pro), a soy protein isolate and a soy protein concentrate. Chocolate chip cookies were prepared replacing 20% of the wheat flour with the soy ingredient. Cookies were evaluated by 75 consumers for color, flavor, texture and overall liking using a 9–point hedonic scale. Data were subjected to ANOVA. Flavor scores of cookies prepared with INTSOY texturized soy protein were significantly higher (7.2) than those of the other three types of cookies (<6.6). There were significant interactions between the degree of color liking of cookies and gender (P < 0.01) and overall liking of cookies and age (P < 0.01). Women liked isolate–containing cookie color better than men; no gender difference existed between other treatments. Consumers over 41 years of age gave Insta–Pro containing cookies higher overall liking scores than other cookies while no difference existed between cookie treatments for consumers between 26 and 40 years of age. The mean scores for color, texture, flavor and overall evaluation for all four cookies were between 6 (like slightly) and 7 (like moderately) on a 9–point scale, indicating that the panel, in general, liked the cookies somewhat, however, room for improvement existed.     

A study on the acceptability and consumer attitude towards parboiled rice

Despite nutritional claims and other advantages that parboiled rice possesses, its consumption is still low in Brazil mainly because of the local preference for milled rice. In the first part of this study, the acceptability of five commercial brands of parboiled and milled rice was assessed by 100 consumers and similar acceptance levels were observed, evidencing that consumers might not reject parboiled rice for its sensory properties. In the second part, 286 consumers were surveyed about their eating habits and attitude towards rice, focusing especially the nutritional value, sensory and convenience aspects of parboiled rice. In the survey 35% of the respondents were unaware of parboiled rice. Cluster analysis performed on data grouped consumers in one segment with positive attitude and in two other segments with negative attitude towards parboiled rice. Segmentation was mainly because of negative beliefs about the sensory characteristics of the product, although its nutritional claims were unknown to most respondents, revealing the need of marketing efforts focused on informing consumers the health benefits and convenience of eating parboiled rice.     

References to home-made and natural foods on the labels of ultra-processed products increase healthfulness perception and purchase intention: Insights for policy making

As nutritional recommendations change, new marketing strategies are expected to appear on food labels to convey the idea that products are healthful and aligned with the recommendations. In this context, the objective of the study was to evaluate the effect of references to ‘home-made’, images of natural foods and nutritional warnings on consumers’ healthfulness perception and purchase intention of labels of ultra-processed products with excessive content of nutrients associated with non-communicable diseases (NCDs). The study was conducted with 790 Uruguayan Facebook users (65% female, 18–89 years old), diverse in terms of educational and socio-economic levels. A choice experiment involving labels of four categories of ultra-processed products (burgers, cookies, instant soup and instant vanilla milk custard) was implemented. For each product category, eight sets of two labels differing in the presence of references to home-made, images of natural foods and nutritional warnings were designed. Half of the participants were asked to indicate the healthier product, whereas the other half were asked to indicate the product they would purchase. Data were analyzed using mixed logit models. The inclusion of references to home-made and images of natural foods on the labels had a positive effect on purchase intention and tended to create the belief that products were healthful. Nutritional warnings decreased healthfulness perception and discouraged participants' choice. In three of the product categories images of natural foods created a health halo that reduced the effect of nutritional warnings on product choice. Results from the present work suggest the need to develop stricter labelling regulations for ultra-processed products with high content of nutrients associated with NCDs.     

Effect of king palm (Archontophoenix alexandrae) flour incorporation on physicochemical and textural characteristics of gluten-free cookies

The replacement of the blend of rice flour (70%) and corn starch (30%) with king palm flour [ Archontophoenix alexandrae (F. Muell.) H. Wendl. and Drude] at levels of 0–30% was investigated for its effects on the chemical and physical characteristics of gluten-free dough and cookies. Cookies containing 10, 20 and 30% of king palm flour were analysed by twenty-one celiac consumers through preference-ranking test. Ash, minerals, and dietary fibre contents increased in cookies that were added with king palm flour. Compared with the control dough, the incorporation of king palm flour increased the firmness and decreased the adhesiveness of dough samples. The incorporation of king palm flour increased the hardness of cookies in relation to the control dough. None of the cookies differed significantly ( P  > 0.05) in the lightness (L*) parameter. All formulations produced cookies with hue angles around 60, which indicate a tendency to brown colour. The study reveals that the incorporation of king palm flour showed desirable results in nutritional characteristics, because of the increase of the dietary fibre and minerals contents. In this study, the cookies preferred by celiac consumers were those containing 10 and 20% of king palm flour ( P  > 0.05).     

Mitigating effect of amaranth (Amarantus hypochondriacus) protein on acrylamide formation in foods

The effect of addition of amaranth flour and amaranth protein isolate to both a glucose/asparagine model system and real foods (cookies, fried tortilla chips, and baked tortilla chips) was studied to analyse the acrylamide mitigating potential of this underexploited plant with attractive nutraceutical properties. Addition of amaranth flour, with a relatively low protein content (16.45%), did not mitigate acrylamide in either the model system or the studied foods. On the contrary, addition of amaranth protein isolate decreased acrylamide content by 35–40% in the model system, 89% in cookies, 51% in fried tortilla chips, and 62% in baked tortilla chips. This acrylamide reduction was obtained without change in the colour or the texture of the cookies. On the contrary, colour remained unchanged in tortilla chips, but the addition of amaranth protein isolate increased the hardness (16–36%) of the produced tortillas. Although a much more detailed sensory evaluation of cookies and tortilla chips prepared using amaranth protein isolate is needed, the above results suggest that the use of amaranth protein may be an interesting way to both mitigate acrylamide formation and improve nutritional properties of foods.     

Utilization of watermelon rind waste as a potential source of dietary fiber to improve health promoting properties and reduce glycemic index for cookie making

Watermelon rind powder (WRP) is a rich source of dietary fiber and bioactive compounds, hence it could be used in the development of functional foods such as cookies. Different replacement levels of wheat flour with either WRP or hi-maize starch (HMS) (10-30%) on the quality of the cookies made were studied. The dietary fiber content in the cookies increased with incorporation of increasing level of either WRP or HMS. Increasing the proportion of the WRP in the cookie making resulted in an increase in the total phenolic content, 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity, and the ferric reducing antioxidant power. Using up to 20% of WRP and 30% of HMS in the cookie making promotes: increase in dietary fiber, decrease in predicted glycemic index to medium (for WRP) and low (for HMS) levels, and improving the antioxidant activity. These changes still produce an acceptable cookie.     

Physiological and Nutraceutical Perspectives of Fructan

Functional and nutraceutical foods have captured the global market owing to trends and perceptions of consumers on the natural products and diet-health linkages. Health promoting potential of such foods has been attributed to the presence of essential bioactive moieties. Wheat, being staple food in many parts of the world, gained substantial attention of researchers particularly for the extraction of various functional components. Among these, fructan oligosaccharides in nature bestow quality of baked products and provide protection against various physiological disorders. Addition of fructan in various baked products enhances softness and color, especially in bread, and also imparts textural improvement. Moreover, fructans boost mineral absorption, hypocholesterolemic, and hypoglycemic perspectives, bifidogenic nature and controlling cancer insurgence. The benefits allied with fructan are mainly dose and time dependent. In this context, its industrial applications for vulnerable groups are increasing worldwide.     

The effect of brand names on flavor perception and consumption in restrained and unrestrained eaters

In an increasingly obesogenic food environment, making healthful food decisions can be difficult. Because consumers are often bombarded with excessive information about foods they often rely on simple heuristics to decide whether to purchase or consume a food. In the present study we tested females who were either restrained (n = 33) or unrestrained (n = 33) to determine whether their sensory perception and intake of a food would be affected by brand information. Participants were provided with in an ad libitum snack of cookies which was labeled with a brand typically associated with healthful snacks or a brand associated with unhealthful snacks. Results indicated that all participants rated the cookies with the healthful brand label as more satisfying and as having a better taste and flavor. Furthermore, restrained eaters consumed more of the healthful brand than the unhealthful brand, whereas unrestrained eaters’ consumption did not differ. Thus it appears that food-related beliefs do influence consumers’ intake, especially that of restrained eaters. Further research is warranted to investigate these beliefs in order to improve recommendations for healthful eating in a society facing an increased prevalence of overeating and obesity.     

The application of hierarchical clusters analysis to the study of the composition of foods

The nutritional value of prepared foods is frequently questioned or requested at restaurants by its costumers. Therefore, this paper aimed to apply HCA to categorize foods according to their nutritive values. Fifty three samples of prepared foods from four different restaurants were analyzed for proximate composition using the AOAC methods [AOAC (1995). Association of Official Analytical Chemists. Official method of analysis. Arlington, Cereal foods, Supplement (pp. 7–11).]. The multivariate statistical analysis of data using the hierarchical cluster analysis (HCA) technique was obtained through the SPSS (10.0) program. French fries were the most caloric preparation; they also have considerable total fiber content. Milled white rice is rich in carbohydrates; and calories and fiber-poor. Arugula offers the highest protein and total fiber content, whereas lettuce presented the smallest amount of these two nutrients. Beans are the main source of dietary fiber and have a low caloric value. The most caloric preparations are French fries and fried zucchini Milanese Type of processing employed in preparing the foods might account for the variation in results between the establishments studied HCA was a useful guide for looking at and analyzing the different types of foods comparatively. Given how easy it is to calculate this with software, it is recommendable to be used even as an exploratory tool, capable of aiding intuition in the analysis of the set of data. HCA can be useful guide/tools to educate consumers on the nutritive values of foods selling in a restaurant and to help the consumers to select the foods which are suitable to their help, if required.     

Healthier meat products as functional foods

A promising approach to improving health care would be to produce a healthier food supply as a preventive health care strategy. The food supply could be improved by producing functional foods that have nutritional profiles that are healthier than conventional products. However, production of functional foods is not always easily accomplished since they must also taste good, be convenient and reasonably priced so that consumers will regularly purchase and use the products. Meats have great potential for delivering important nutrients such as fatty acids, minerals, dietary fiber, antioxidants and bioactive peptides into the diet. However, to produce successful products with these ingredients, technologies must be developed to increase their stability and decrease their flavor impact on muscle foods. In addition, many regulatory hurdles must be overcome for the commercial production of meats with added nutrients. These include redefinition of standard of identities and policies that allow front of the package nutritional claims. Without these regulatory changes, production of healthier meat products won't become a reality since these products would not have a competitive advantage over unfortified meats.     

Optimising the delivery of food allergy information. An assessment of food allergic consumer preferences for different information delivery formats

In this study, the preferences of food allergic consumers for different prototype information delivery tools was examined, with the aim of improving informed product choices. Sixty-two self-reported food allergic participants from the Netherlands and Germany were included in the study. Each tested three prototype information delivery tools (a food label, a handheld electronic scanner, and an information booklet) to access allergy information. Participants rated each tool in terms of perceived convenience, usefulness and confidence. Principal Component Analysis indicated that convenience and usefulness loaded on one construct, namely functionality. The impact of information delivery tool and country on functionality and confidence was analysed with two repeated measures generalised linear models. The highest perceived functionality was found for the label. The electronic scanner was rated as the next most functional method to deliver information, followed by the booklet. Food allergic consumers were equally confident about using all three information delivery tools. The results have implications for developing new policies and legislation concerning information provision to food allergic consumers.     

Impact of nutritional claims on consumer preferences for bread with varied fiber and salt content

High consumption of bread provides a lot of salt, but it can also provide a lot of fiber to the diet. The use of labels on bread could encourage consumers to choose bread with improved nutritional value, i.e., with reduced salt and increased fiber content. The aim of the study was to explore the impact of the different nutritional information on preferences regarding bread (wheat plain roll) with reduced sodium content and bread enriched with fiber. The survey was carried out among a group of 330 adult consumers in 2015 in the southern part of Poland. The conjoint analysis design included four product attributes – two nutritional claims (“Low salt content” and “Source of dietary fiber”), fiber content, and salt content. The mean part-worth utilities of individual product attributes and the relative importance of attributes within the sample were calculated using SAS procedures. Next, cluster analysis, based on the individual utilities, was undertaken to identify groups (clusters) of consumers with similar preferences. Salt content had higher relative importance for the participants in comparison with both claims, while the relative importance of dietary fiber content was the lowest. The relative importance of both nutritional claims was almost equal, namely 25.5% for the fiber claim and 25.4% for the salt claim. The results of cluster analysis showed strong heterogeneity in consumer reactions to the attributes of the tested product. To conclude, providing information about the salt and fiber content of bread is necessary to encourage a healthy choice, but the claims placed on bread packaging seem to be insufficient as they contribute to the avoidance of the product. Increasing consumer awareness of nutrition claims of foods is required.
