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.
大量关注集中在食用鱼油显然具有的各种健康益处上。鱼油在食品中的添加越来越普遍,各种各样的产品正在市场上销售。然而,鱼油作为食品中的功能性营养成分的使用受到其氧化敏感性的限制。在本研究中,尝试通过加入鱼油微胶囊来开发富含鱼油的饼干作为健康休闲食品。鱼油的微胶囊化通过喷雾干燥完成。使用市售牛奶与鱼油形成微尺寸复合物。鱼明胶/麦芽糊精用作包封的壁材。为制备饼干,以三种形式添加鱼油(即原样鱼油、水包油乳液和鱼油微胶囊)。不添加鱼油制备的饼干用作对照。对饼干的物理、化学和感官特性进行了评估。微胶囊化显著(P < 0.05)降低了饼干中的脂质氧化。饼干的感官评价显示总体可接受性存在显著(P < 0.05)差异。本研究结果表明,通过乳化和微胶囊化将鱼油加入饼干中的可能性,这可能增加ω-3脂肪酸的摄入量以获得营养益处。
