以红枣粉、奶粉为主要原料,通过单因素和正交试验相结合,以离心沉淀率为评价指标确定红枣奶饮料中稳定剂最佳配比;在此基础上,采用模糊数学综合评价法确定红枣奶饮料最佳配方。结果表明,最佳稳定剂配比为黄原胶0.25%、单硬脂酸甘油酯0.15%、瓜尔豆胶0.15%。在此最佳稳定剂条件下,离心沉淀率最低为3.08%;红枣奶饮料的最佳配方为红枣粉8%、奶粉4%、蔗糖2%。在此最佳配方条件下,感官评分为91.53分,风味独特,组织状态良好,质量指标符合相关国标,具有广阔的市场前景。 相似文献

Owing to their health benefits, probiotics and prebiotics are nowadays widely used in yogurts and fermented milks, which are leader products of functional foods worldwide. The world market for functional foods has grown rapidly in the last three decades, with an estimated size in 2003 of ca US$ 33 billion, while the European market estimation exceeded US$ 2 billion in the same year. However, the production of probiotics and prebiotics at industrial scale faces several challenges, including the search for economical and abundant raw materials for prebiotic production, the low-cost production of probiotics and the improvement of probiotic viability after storage or during the manufacturing process of the functional food. In this review, functional foods based on probiotics and prebiotics are introduced as a key biotechnological field with tremendous potential for innovation. A concise state of the art addressing the fundamentals and challenges for the development of new probiotic- and prebiotic-based foods is presented, the niches for future research being clearly identified and discussed. 相似文献
