研究了籼米为基质的脂肪替代品的制备工艺。通过单因素试验研究了耐高温α-淀粉酶添加量、籼米粉目数和水解时间对产品DE值的影响,并通过正交试验确定了制备籼米为基质的脂肪替代品的最佳工艺条件:酶添加量4.0 U/g米粉,水解时间30 min,籼米粉目数100目。制备的产品DE值3.0左右,干燥后产品为白色粉状物。利用提取脂肪替代品后的沉淀继续制备DE值13~17的麦芽糊精,工艺条件为:酶添加量40.0 U/g米粉,水解时间40 min。最后,添加质量分数6%的脂肪替代品和9%的麦芽糊精复配出的速溶咖啡口感最佳。 相似文献

为满足消费者对健康饮食的要求和未来食品供应的可持续性,植物基肉类替代品被广泛开发,具有广阔的市场发展前景。用植物基复合脂肪模拟物代替肉制品中的脂肪,可以减少食物中的脂肪,对消费者的健康有益。本文主要综述了各种胶体对植物基复合脂肪模拟物性质的影响,以便为其在肉制品行业中的应用提供更多的理论支持。多糖类胶体的添加可以提高脂肪模拟物的持水能力,增加肉制品的多汁感;蛋白类胶体可以提高脂肪模拟物的营养特性和弹性,增强咀嚼感和产品质地。此外,通过整理近年来国内外对植物基脂肪模拟物的研究,对植物基脂肪模拟物在肉制品的应用进行了分类和较全面的总结,并基于此阐述了植物基脂肪模拟物对肉制品质量的影响。在肉制品中添加植物基复合脂肪模拟物可以提高肉制品的保水性,在有效地模拟动物脂肪并且不影响产品感官特性的同时延长肉制品的保质期。最后,阐述了块状复合脂肪模拟物开发存在的一些问题和挑战以及潜在的解决方案,为植物替代肉类市场的预期扩张开辟了新的研究方向。 相似文献

脂肪是重要的食品组分,但脂肪的过度摄入会对人体健康产生多种不利的影响,导致肥胖和各种慢性疾病的发生。近年来,随着消费者已经认识到长期高热量饮食的危害,低脂低热量的健康饮食已经成为保障居民身体健康的重要手段。简单的去除脂肪虽能降低食物热量,但会造成食品品质的下降。为解决这一矛盾,学者致力于研究开发脂肪模拟物来代替脂肪,降低食物热量,同时保持食物较好的口感。在众多的脂肪模拟物中,基于碳水化合物的脂肪模拟物因安全性高,成本低,相容性好等优势已经成为最重要的脂肪模拟物。本文总结了脂肪模拟物的发展、分类、特点和基本脂肪模拟机制,重点介绍了碳水化合物基脂肪模拟物模拟脂肪口感的作用机制、影响风味特性的机制和发挥低热量作用的机制,阐述了以淀粉、菊粉、麦芽糊精、纤维素等为基质制备的低热量脂肪模拟物在食品中应用情况,总结了脂肪模拟物的几种制备方法,最后提出了未来发展的建议。 相似文献

脂肪替代品在烘焙行业中的研究进展 总被引:2,自引:0,他引:2
用脂肪替代品替代烘焙产品中的脂肪,可维持食物本身的美味且减少脂肪含量,有利于消费者的健康,具有广阔的市场前景。为了给脂肪替代品在烘焙行业中的应用提供更多的理论支持,该文讨论了脂肪的形式及其在烘焙产品质构和感官品质方面的作用,并从脂肪替代物(olestra和salatrim)、脂肪模拟物(淀粉、改性淀粉、麦芽糖糊精、聚葡萄糖、胶体、纤维素和蛋白质)和复合型脂肪替代物3个方面对国内外低脂烘焙产品特点以及应用进行总结分析,最后对烘焙产品中脂肪替代品的发展方向进行了展望。 相似文献

Americans are becoming more health conscious in their food choices and many are interested in reducing dietary fat intake. Fat replacers can affect meat flavor both by adding flavors of their own, by reducing the original aroma-generating substrate (fat) and by altering release of aroma compounds. When fat is removed from meat, water is generally added to replace it. Water-binding compounds can be added to prevent the added water from cooking out or evaporating and to prevent patty shrinkage. Fat replacers are generally classified by their composition: protein-based replacers including whey, soy and collagen, lipid-based substances such as soy lecithin which function as emulsifiers maintaining the fat that is retained distributed in the product, and carbohydrate-based substances including flours (wheat, soy, oat), starches (potato, modified corn starch, tapioca) and gums (carrageenan, xanthin). Duplication of the characteristics contributed by fat often requires a combination of replacers to address juiciness and texture (firmness) without negatively impacting flavor. 相似文献

Fat replacers are used to alleviate functional and sensory deficits in whipped cream caused by fat reduction. Of all known fat replacers, proteins have shown the most effective ability to replace fat due to their nutritional attributes and functional properties. Recently, several protein-based fat replacers were investigated, but among all of them, the use of milk proteins and modified proteins, especially their complex with polysaccharides presented promising results. Therefore, due to the growing interest in this field, this review focussed on the mechanism for fat replacement with proteins and their complexes, and the characteristics of low-fat whipped cream affected by these proteins, and finally considered the challenges and perspectives in the future. 相似文献

Cheeses with 60% reduced fat were prepared with three fat mimetics and viscoelasticity was studied. Storage and loss moduli of low-fat cheeses made with a carbohydrate-based fat mimetic were greater (p < 0.05) than those of low-fat cheeses made with two protein-based fat mimetics or low-fat control cheese, but smaller (p < 0.05) than the storage and loss moduli of full-fat cheese. A six-element Kelvin model properly predicted the creep compliance for the full-fat cheese and the low-fat cheeses made with or without fat mimetics. Low-fat cheese made with a carbohydrate-based fat mimetic had a network structure more similar to full-fat cheese than the low-fat control or samples made with protein-based fat mimetics. 相似文献
