This research aimed to assess consumers' knowledge, perception, and practical understanding of food labels. A validated, structured questionnaire was employed for data collection. Data were collected from 1238 respondents covering all eight administrative divisions of Bangladesh using a nonrandomized convenience sampling method. Linear regression analyses were conducted to establish the relationship between demographic attributes and respondents' practical understanding of food labels. The majority of participants (52.5%) actively read food labels when purchasing a product for the first time. Food labels are regarded as “very important” by 56.2% of respondents and “important” by 35.7% of respondents. Label information is prioritized to highlight the importance of clear production and expiration dates (70%), followed by nutritional composition (56.7%) and source of raw material (52.5%). Despite this, over half of the participants demonstrated a limited practical understanding of the nutritional components on labels. The results of our linear regression analysis suggest that individuals within the age range of 18–28, belonging to Muslim communities, residing in the Dhaka and Khulna divisions, being higher educated, possessing a good understanding of nutrition, and being acquainted with the food safety agency of Bangladesh tend to exhibit a greater degree of practical knowledge regarding food labeling when compared to their counterparts. The study emphasizes the importance of clearer label information, particularly for nutritional value, and calls for targeted educational programs to improve consumer understanding of food labels, with a focus on older age groups and expanded educational efforts. 相似文献

The need for accurate nutrition labeling on food products has never been greater. Obesity has assumed near-epidemic levels in both industrialized and emerging nations in recent years, and governments and consumer groups around the world are looking for ways to improve the nutritional choices for their citizenry while simultaneously balancing their freedom of choice through the use of nutrition labeling. Despite increasingly aggressive efforts by government and industry organizations to raise consumer awareness, though, many consumers either do not consult nutrition labels or they are not in a position to interpret the information on these labels accurately. To gain some fresh insights into nutrition labeling practices worldwide, this paper provides a review of the relevant peer-reviewed, scholarly, and government literature to describe regulations enacted to date, evolving and future trends, and the likely impact of food product labels. In this regard, the paper highlights similarities and discrepancies that exist, identifies gaps, and gives directions for the future. 相似文献

Abstract: The effect of sensory and extrinsic attributes on consumer intentions to purchase the Japanese traditional fermented soybean product natto was evaluated using conjoint analysis. Six attributes with 2 levels each were chosen and manipulated: price (high compared with low), the country of origin of the soybeans (domestic compared with imported), stickiness (strong compared with moderate), smell (rich compared with moderate), attached seasonings (attached compared with no attached seasonings), and the environmental friendliness of the packaging (high compared with low). A fractional factorial design was applied and 8 hypothetical product labels were produced. A sample of 479 Japanese housewives ranked these product labels based on their purchase intentions. Overall purchase intention was affected by country of origin, attached seasonings, and price; those attributes accounted for 81.0%, while the sensory attributes of the product accounted for 19.0% of purchase intents. In order to estimate market segments for the natto products based on consumer preference, a cluster analysis was performed. It identified 4 segments of consumers: 1 oriented to attached seasonings, another conscious of the price, and the other 2 oriented to origins. The behavioral and demographic characteristics of the respondents had a limited influence on segment membership. Practical Application: This research was conducted to understand how consumers valuate various sensory and nonsensory product attributes based on their assessment of the overall product in the case of Japanese fermented soy product (natto). The data of this research would be of great importance both in understanding consumer behavior and in designing strategies for product development. 相似文献

Nutrition is recognized as one of the leading factors influencing the growing incidence of noncommunicable diseases. Despite society experiencing a global rise in obesity, specific populations remain at risk of nutrient deficiencies. The food industry can use health claims to inform consumers about the health benefits of foods through labeling and the broader promotion of specific food products. As health claims are carefully regulated in many countries, their use is limited due to considerable investments required to fulfill the regulatory requirement. Although health claims represent a driving force for innovation in the food industry, the risk of misleading of consumers need to be avoided. The health claim scientific substantiation process must be efficient and transparent in order to meet the needs of companies in the global market, but should be based on strong scientific evidence and plausible mechanisms of actions, to ensure highest level of consumer protection. The objective of this review is to compare the possibilities for using health claims on foods in the European Union, the USA, Canada, and Australia and New Zealand. In particular, we focused on differences in the classification of claims, on the scientific substantiation processes and requirements for health claims use on foods in the selected regions. Reduction of disease risk (RDR) claims are associated with relatively similar procedures and conditions for use, whereas several notable differences were identified for other types of claims. In all cases, RDR claims must be approved prior their introduction to the market, and only a few such claims have been authorized. Much greater differences were observed concerning other types of claims. 相似文献

ABSTRACT: The objective of this study was to utilize a multiobjective optimization technique for the thermal sterilization of packaged foods. The multiobjective optimization approach used in this study is based on the optimization of well-known aggregating functions by an adaptive random search algorithm. The applicability of the proposed approach was illustrated by solving widely used multiobjective test problems taken from the literature. The numerical results obtained for the multiobjective test problems and for the thermal processing problem show that the proposed approach can be effectively used for solving multiobjective optimization problems arising in the food engineering field. 相似文献

Previous studies demonstrated that variability in oral processing behaviors impacts bolus properties and consequently texture and flavor perception. However, most studies followed a prescribed mastication protocol during the products’ sensory evaluations. A better understanding of how variability in habitual eating behavior impacts sensory perception of foods is needed. The aim of this study was to investigate the effect of habitual eating speed (slow vs. fast eaters) on dynamic sensory perception of composite foods. Habitual oral processing behavior of different composite foods was quantified in 105 participants. Participants were divided in fast (n = 53) and slow (n = 52) eaters using a median split. Three formulations of strawberry jams varying in viscosity and sugar content (High Sugar/Low Pectin [Control], High Sugar/High Pectin, Low Sugar/Low Pectin) were used. Composite foods were prepared by spreading jams on breads. Dynamics of dominant sensory attributes of strawberry jams presented with and without breads were evaluated using Temporal Dominance of Sensations (TDS). Dynamic sensory perception of jams and jam–bread combinations differed only slightly for short periods of time between habitual slow and fast eaters. The addition of breads to jams reduced especially the ability of the fast eaters to discriminate between jams differing in formulation. Slow eaters discriminated between different formulations of jams better than fast eaters, regardless of whether jams were presented alone or in combination with breads. We conclude that differences in habitual eating speed between consumers lead to small differences in dynamic sensory perception and discrimination ability of composite foods. 相似文献

BACKGROUND: In the current context of growing consumer demand for foodstuffs that are healthy and safe and that are obtained in a manner respectful to the welfare of animals, the analysis of consumer preferences towards attributes of this type takes on particular importance. These trends are especially clear in the case of the consumption of eggs because of their strong negative association with cholesterol levels and their extremely intensive systems of production. The introduction of variants that are more in harmony with current consumer demands represents an interesting market alternative. RESULTS: The present study was aimed at investigating the preferences of Spanish consumers for these alternative types of egg that are entering the market. The survey was conducted with 361 consumers from October 2007 to March 2008. The conjoint analysis allowed us to estimate the relative importance of the main attributes that affect consumer preferences for eggs and to distinguish segments of consumers with similar preference profiles. CONCLUSION: It was found that price is the most important attribute determining consumer preferences, followed by the hens' feed and their rearing conditions. It was also found that only some groups of consumers are willing to pay the premium necessary for alternative methods of production. Copyright © 2010 Society of Chemical Industry 相似文献

Avoiding too much sugar is an accepted dietary guidance throughout the world. The U.S. Nutrition Facts panel includes information on total sugars in foods. A focus on added sugars is linked to the concept of discretionary calories and decreasing consumption of added sugars or free sugars as a means to assist a consumer to identify foods that are nutrient‐dense. On March 14, 2014, the U.S. Food and Drug Administration proposed that including “added sugars” declaration on the Nutrition Facts panel would be another tool to help consumers reduce excessive discretionary calorie intake from added sugars. Through deductive reasoning, labeling added sugars is one tactic to potentially curb the obesity epidemic in the United States. This review discusses the functions of sugar in food and shows that the methods used to replace added sugars in foods can result in no reduction in calorie content or improvement in nutrient density. Without clear benefit to the consumer for added sugars labeling, this review highlights the complex business obstacles, costs, and consumer confusion resulting from the proposed rule. 相似文献

European regulations mandate that only substantiated and approved statements can be used as nutrition- and health-related claims in food marketing. A thorough understanding of consumer perceptions of these approved claims is needed to assess their impact on both the purchase intention of functional foods and the development of innovative functional food concepts. In this paper, a conceptual framework on the European consumers’ perception of nutrition and health claims on these functional foods is proposed. Through a literature review, common independent variables are structured, and an analysis of these variables shows that nutrition and health claims are mostly only perceived positive by specific target consumers (who need the product, accept the ingredient, understand the benefit, and trust the brand). These consumers indicate that the products with substantiated and approved claims help them in reaching overall health goals. This increased expectation in functional efficacy may mediate an increase in repurchase intent, overall liking, and the amount consumers are willing to spend. Other consumers, however, may have adverse reactions towards nutrition and health claims on functional foods. Implications for the consumer and the industry are discussed. 相似文献

Numerous examples of next-generation plant-based foods, such as meat, seafood, egg, and dairy analogs, are commercially available. These products are usually designed to have physicochemical properties, sensory attributes, and functional behaviors that match those of the animal-sourced products they are designed to replace. However, there has been concern about the potential negative impacts of these foods on human nutrition and health. In particular, many of these products have been criticized for being ultraprocessed foods that contain numerous ingredients and are manufactured using harsh processing operations. In this article, the concept of ultraprocessed foods is introduced and its relevance to describe the properties of next-generation plant-based foods is discussed. Most commercial plant-based meat, seafood, egg, and dairy analogs currently available do fall into this category, and so can be classified as ultraprocessed plant-based (UPB) foods. The nutrient content, digestibility, bioavailability, and gut microbiome effects of UPB foods are compared to those of animal-based foods, and the potential consequences of any differences on human health are discussed. Some commercial UPB foods would not be considered healthy based on their nutrient profiles, especially those plant-based cheeses that contain low levels of protein and high levels of fat, starch, and salt. However, it is argued that UPB foods can be designed to have good nutritional profiles and beneficial health effects. Finally, areas where further research are still needed to create a more healthy and sustainable food supply are discussed. 相似文献
