Bamboo shoot preservation for enhancing its business potential and local economy: a review

Bamboo shoot as food has been used in traditional ways by the tribal community the world over. For enhancing its business potential, research on various aspects of bamboo shoot as food is being carried out in Japan, Taiwan, Thailand, and Asian countries and several products are available in the market. Bamboo shoots are used as a delicacy in human food, are a good source of dietary fiber, low in fat and calories. The research studies included in this review paper focus on post-harvest preservation of bamboo shoot. In view of the seasonal availability of bamboo shoot, the post-harvest preservation system for handling cynogenic toxicity in raw shoot while keeping nutrients intact and enhancement of shelf life of the value added products assume great significance for the business potential of this natural product. A yardstick of assessing the "Shelf life-Quality Matrix" developed in this review paper would give a new perspective of quality control in case of preservation of bamboo shoot. Also, knowledge gaps identified in this paper would give impetus to new academic and R&D activities, in turn generating an innovative job profile in the food industry as well as rural entrepreneurship.

Factors affecting the water holding capacity of red meat products: a review of recent research advances

The water holding capacity of meat products is a very important quality attribute which has an influence on product yield, which in turn has economic implications, but is also important in terms of eating quality. A number of pre-and post-mortem factors influence the water holding capacity (WHC) of meat. During the growth and development of meat animals, genotype and animal diet are important due to their direct influence on muscle characteristics. In the immediate pre-slaughter period, stresses on the animal such as fasting, and different stunning methods are likely to influence meat WHC. In the post-slaughter period chilling, ageing, injecting non-meat ingredients, as well as tumbling have important influences on WHC. Furthermore, cooking and cooling procedures for the final meat products can also affect the WHC of the product, in particular the cooking and the cooling methods, the heating and the cooling rate, the cooking temperature, and the endpoint temperature. This paper provides an overview of recent research on important intrinsic and extrinsic factors that affect the WHC of beef, pork, and lamb products, and reveals explanations and solutions to some of the critical problems related to WHC and product quality.

Food processing by high hydrostatic pressure

The use of high hydrostatic pressures (HHP) for food processing is finding increased application within the food industry. One of the advantages of this technology is that because it does not use heat, sensory, and nutritional attributes of the product remain virtually unaffected, thus yielding products with better quality than those processed traditional methods. HHP have the ability to inactivate microorganisms as well as enzymes responsible for shortening the life of a product. In addition to lengthening the shelf-life of food products, HHP can modify functional properties of components such as proteins, which in turn can lead to the development of new products. Equipment for large-scale production of HHP processed products are commercially available nowadays. Guacamole, sliced ham, oysters, and fruit juices are some of the products currently available on the market. HHP technology is one of the most promising nonthermal processes.

IMPROVING THE QUALITY AND SHELF LIFE OF TURKISH ALMOND PASTE

Almond paste is an economically valuable product produced from almonds, sugar and a small amount of water. Oxidative rancidity and oil separation are the major problems that are encountered in the paste products affecting the shelf life. Another problem appears to be drying on the surface of the product resulting in poor consumer acceptability. In this study, the formulation of product was altered by adding a commercial stabilizer, antioxidant mixture and maltose syrup to prevent undesirable quality changes during storage at 4C and 30C. Peroxide value, free fatty acid and Rancimat analysis showed that the addition of antioxidant mixture prevented oxidation effectively and improved sensory scores significantly ( P ≤  0.05). Although stabilizer addition had a detrimental effect on the textural properties, samples that have maltose had high sensory scores. The results showed that incorporation of maltose syrup and antioxidant may improve the texture and shelf life of almond paste.

PRACTICAL APPLICATIONS

The available literature on almond paste is mainly focused on the microbiological quality of the product and the prevention of spoilage reactions by modifying packaging materials. However, there is no report on the optimization of the composition to extend the shelf life of almond paste. Turkish almond paste, a healthy and expensive dessert, is a specialty product that is manufactured by using traditional grinding equipment. However, the limited shelf life of this product decreases its export potential resulting in economical losses. Therefore, improved shelf life and quality of the product is of importance from the economical point of view. In our study, we aimed to improve the quality and shelf life of Turkish almond paste by modifying its formulation in order to minimize the undesirable changes that occur during storage.     

Launching Products Towards the Right Target

Abstract

The textile and apparel industries are under constant pressure to develop and introduce new products; product development is a cornerstone in the survival strategy of any company in these industries. Yet, the development cycles are lengthy and usually require several feedback loops, often showing a mismatch of product properties, cost, and requirements.

Other assembly-oriented industries have successfully used managerial tools to integrate the product development process with marketing, product costing, and procurement functions. This paper discusses the use of product development tools (e.g. quality–function–deployment matrix) and target costing as an integrated approach for the textile and apparel industries. With the help of a case study it is shown how this integrated approach can reduce product development cycle time by focusing technical research, and how to incorporate desirable features in the new product design to gain customer satisfaction.

The integrated approach facilitates the development of new products that are competitively priced and earn projected profits in a target market niche.     

From salad to bowl: The role of sensory analysis in product experience research

Methods originally developed for the sensory evaluation of foods are increasingly being applied to other product categories, ranging from personal care products to car interiors and air conditioning units. Furthermore, because an increasing number of food products tend to be available in packages from which they can be consumed directly, the sensory properties of packages have become an integral part of consumers’ food experiences and require thorough investigation. In addition, food consumption in everyday life takes place within a physical, social, and cultural context. This asks for a reconsideration of the role of sensory analysis in the product development process. To seduce consumers in highly saturated markets, products should not only provide good quality and be appealing, but they should offer interesting and engaging experiences. Therefore, research on sensory evaluation needs to be linked to research on product aesthetics, product meaning, and product emotions. Capturing the entire consumer experience requires an integral approach, in which research approaches from various academic fields are combined and integrated. For this approach to succeed in industrial companies, many different departments will need to work together in close cooperation.     

Using a consumer-driven rapid product navigation process to develop an optimal product

There are many different approaches to product optimization, each with its own strengths and limitations. To address some of these limitations, a unique, consumer-driven approach was developed to rapidly navigate a path through a qualitative product space (QPS) to reach the product that best meets the product sensory criteria, rather than having to evaluate all products in the design and build models to determine the optimum as in classic design of experiments. During this rapid product navigation (RPN) process, consumers participate in a unique form of qualitative discussion groups, during which prototypes are evaluated and discussed in-depth, with the group’s response to each prototype determining the next prototype to be presented. This adaptive, stimulus–response process is a listening and learning approach rather than a modeling approach and provides a deeper understanding of not only what the best product is, but also why it is the best. Due to the strong partnership required between the product researcher and product development, the business also gains a deeper understanding of consumer language and key design elements, which then feeds back into future product development projects. It is also possible to identify potential consumer segments that may not be obvious from traditional sensory evaluation and ensure that the resulting product design meets the product sensory requirements for the intended audience. This approach to developing the optimal product has demonstrated multiple successes, cutting product development time from 18–24 months to less than 6 months.

Assessment of the long-term stability of retort pouch foods to support extended duration spaceflight

To determine the suitability of retort processed foods to support long-duration spaceflight, a series of 36-mo accelerated shelf life studies were performed on 13 representative retort pouch products. Combined sensory evaluations, physical properties assessments, and nutritional analyses were employed to determine shelf life endpoints for these foods, which were either observed during the analysis or extrapolated via mathematical projection. Data obtained through analysis of these 13 products were later used to estimate the shelf life values of all retort-processed spaceflight foods. In general, the major determinants of shelf life appear to be the development of off-flavor and off-color in products over time. These changes were assumed to be the result of Maillard and oxidation reactions, which can be initiated or accelerated as a result of the retort process and product formulation. Meat products and other vegetable entrées are projected to maintain their quality the longest, between 2 and 8 y, without refrigeration. Fruit and dessert products (1.5 to 5 y), dairy products (2.5 to 3.25 y), and starches, vegetable, and soup products (1 to 4 y) follow. Aside from considerable losses in B and C vitamin content, nutritional value of most products was maintained throughout shelf life. Fortification of storage-labile vitamins was proposed as a countermeasure to ensure long-term nutritive value of these products. The use of nonthermal sterilization technologies was also recommended, as a means to improve initial quality of these products and extend their shelf life for use in long-duration missions. Data obtained also emphasize the importance of low temperature storage in maintaining product quality. PRACTICAL APPLICATION: Retort sterilized pouch products are garnering increased commercial acceptance, largely due to their improved convenience and quality over metal-canned products. Assessment of the long-term stability of these products with ambient storage can identify potential areas for improvement, and ultimately increase consumer satisfaction with these technologies.
