Purpose: This study examined the influence of the consumption values on the attitudes and purchase intentions of consumers towards gluten-free products and compared consumption values, attitudes and purchase intentions according to the degree of health consciousness of the consumer. Methods: The data was collected from July 20, 2016 to August 2, 2016 through a questionnaire survey from three hundred and six consumers who had knowledge of gluten-free products. The data was analyzed by factor analysis, reliability analysis, multiple regression analysis, and an independent sample t-test using the SPSS program. Results: The regression results showed that the exploratory value (p<0.01) had a negative influence on the attitudes, and the functional value (p<0.001) and emotional value (p<0.001) had a positive influence on the consumers' attitudes. In addition, the attitudes (p<0.001) toward gluten-free products had a positive influence on the purchase intentions. Finally, the high health consciousness group answered with a significantly higher score on the consumption values, attitudes and purchase intentions than the lower group. Conclusion: These results highlight the causal relationship among consumption values, attitudes, and purchase intentions of consumers towards gluten-free products, and can provide a basic understanding of gluten free products regarding both marketing strategy and consumers' needs. The potential implications for gluten-free products manufacturers, limitations and future research directions are also discussed.

Camel milk has a significant and pivotal role in the diet of people residing in semi-arid and arid regions. Ever since ancient times, marketing of camel milk has remained insignificant due to nonexistence of processing amenities in the camel nurturing areas, hence the utilization of unprocessed camel milk has continuously remained limited at family level by the nomads. Due to the superior medicinal values and health promoting effects, incredible growth in the demand of camel milk and dairy products have been noticed all over the world during last two decades. Such emergence has led dairy industry to provide diversified camel dairy products to the consumers with superior nutritional and functional qualities. In contrast to bovine, very few food products derived from camel milk are available in the present market. With the advancements in food processing interventions, a wide range of dairy and non-dairy products could be obtained from camel milk, including milk powder, cheese, yogurt, ice cream, and even chocolate. In some regions, camel milk is used for traditional dishes such as fermented milk, camel milk tea, or as a base for soups and stews. Current review highlights the processing opportunities regarding the transformation of camel milk into various dairy products via decreasing the inherent functionality that could be achieved by optimization of processing conditions and alteration of chemical composition by using fortification method. Additionally, future research directions could be devised to improve the product quality.

Since Stewartia koreana leaves are registered with the Food and Drug Administration as edible herbal materials, they are used in the development of functional foods, cosmetics, and medicines. In this study, we established an analysis method that can simultaneously analyze two indicators, hyperoside (quercetin 3-O-galactoside) and isoquercitrin (quercetin 3-O-glucoside) contained in the leaves of S. koreana using HPLC-DAD. In accordance with the Ministry of Food and Drug Safety's health functional food guidelines, the analysis method was verified for specificity, accuracy, precision, limit of quantification, and linearity. The analysis method established in this study showed more than 0.9989 of the correlation coefficient values (r²) for the calibration. The total recovery rates of isoquercitrin and hyperoside were 100.55 and 98.87% with 0.14-0.78 and 0.47-0.67% of the relative standard deviation, respectively. Therefore, it was suggested that the new analytical method would be applied to standardize raw materials and high value-added products originated from the leaves of the S. koreana in the future.

The beneficial effects of fruits, vegetables, and beverages on human health have been attributed to their antioxidant activities. Therefore, antioxidant activity of food products is recognized as one of the important parameters in determining their functional values. Until now, antioxidant activity has been measured by various chemical and biological methods; however, many factors confound the reliability and reproducibility of measurements of antioxidant activity of food. In vitro methods may provide a useful indication of antioxidant activity but their results may not translate to the human biological system, while in vivo tests are difficult to carry out due to the intricate processes of uptake, cellular transportation, and metabolism of individual antioxidant components. Therefore, as long as these limitations exist, our best option is to measure the antioxidant activity in food directly. This review briefly summarizes currently available methods for the measurement of antioxidant activity in food and examines their respective validity.

Spirulina is known to be more useful abroad than in Korea because it contains more protein than Chlorella, the same microalgae. In the past, sources of animal protein were diverse, but since it takes a long time to receive protein along with environmental pollution, we thought that spirulina could attract attention as a new protein source. In this study, application cases were analyzed in foods in the fields of acorn cake, tofu, dumpling skin, fish cake, white bread, pound cake, salad dressing, and yogurt and so on. As a result of centrally analyzing antioxidant and sensory evaluation, it was confirmed that the results were effective enough to develop products in tofu, dumpling skin, fish cake, and pound cake. It is thought that development of food in other fields will be possible if an additive amount that can match the consumer's preference is found by supplementing the mixing ratio. If it is used as a main raw material for existing food rather than as a raw material for health functional food, consumer preference can increase and quality can be further improved, and it can be suggested as a good alternative for an aging society.

Structured lipids are lipids in which the composition and/or positional distribution of fatty acids have been chemically or enzymatically modified from their natural biosynthetic form. Because structured lipids have desired nutritional, physicochemical, textural or physiological properties for applications in processed foods, functional foods, or nutraceuticals, many research activities have been aimed at their commercialization. The enzymatic production of structured lipids using lipases as the biocatalysts has a big potential in the future market due to the specificity or selectivity of the lipases. This article introduced some examples of specialty structured lipids that have been enzymatically produced and have been utilized as commercialized products. The commercialized products include medium- and long-chain triacylglycerols, human milk fat substitutes, cocoa butter equivalents, trans-free plastic fats, low-calorie fats/oils, and health-beneficial fatty acid-rich oils.
