Abstract

A great deal of attention has been focused on the various health benefits apparently associated with consumption of fish oil. The incorporation of fish oils in food products is becoming increasingly widespread and a large variety of products is being marketed. However, the use of fish oil as functional nutritional ingredients in foods has been limited by its oxidative susceptibility. In the present study, attempts were made to develop fish oil fortified cookies as healthy snack foods by incorporating fish oil microencapsulate. Microencapsulation of fish oil was done by spray drying. Commercially available milk was used to form micro sized complexes with fish oil. Fish gelatin/maltodextrin were used as a wall material for encapsulation. Fish oil was added in three forms (fish oil as such, fish oil-in-water emulsion and fish oil microencapsulate) for the preparation of cookies. Cookies prepared without incorporating fish oil was served as control. The physical, chemical and sensory attributes of cookies were evaluated. Encapsulation significantly (P < 0.05) decreased lipid oxidation in the cookies. The sensory evaluation of cookies showed significant (P < 0.05) difference in the overall acceptability. Results from this study, demonstrated the possibility of fish oil incorporation into cookies through emulsification and microencapsulation which may increase the intake of omega-3 fatty acids for nutritional benefits.

加入鱼油胶囊对饼干理化和感官特性的影响

食用鱼油对健康的各种益处显然受到了广泛关注。在食品中添加鱼油的做法越来越普遍，市场上也出现了大量不同的鱼油产品。然而，鱼油作为功能性营养配料在食品中的使用却受到其易氧化性的限制。本研究尝试通过加入鱼油微胶囊来开发鱼油强化饼干，作为健康的休闲食品。鱼油的微胶囊化是通过喷雾干燥法完成的。市售牛奶被用来与鱼油形成微小尺寸的复合物。鱼明胶/麦芽糊精被用作封装的壁材。鱼油以三种形式（鱼油本身、鱼油水乳剂和鱼油微胶囊）添加到饼干中。未添加鱼油的饼干作为对照。对饼干的物理、化学和感官属性进行了评估。胶囊化效果明显（P

期刊介绍： The Journal of Food Science and Technology (JFST) is the official publication of the Association of Food Scientists and Technologists of India (AFSTI). This monthly publishes peer-reviewed research papers and reviews in all branches of science, technology, packaging and engineering of foods and food products. Special emphasis is given to fundamental and applied research findings that have potential for enhancing product quality, extend shelf life of fresh and processed food products and improve process efficiency. Critical reviews on new perspectives in food handling and processing, innovative and emerging technologies and trends and future research in food products and food industry byproducts are also welcome. The journal also publishes book reviews relevant to all aspects of food science, technology and engineering.
