从益生菌的使用状况出发,为研发新的益生菌酸奶产品提供依据。采用GNPD数据库分析国内市场上新品益生菌酸奶的益生菌添加种类,并通过选择性培养方式检测在售的几款益生菌酸奶产品中益生菌的含量。通过GNPD搜索到的61份新品益生菌酸奶中,添加嗜酸乳杆菌和双歧杆菌的分别占总量的52.5%和67.2%,且嗜酸乳杆菌和双歧杆菌组合添加的比例达到45.9%。对几款益生菌酸奶产品中益生菌含量进行检测,益生菌活菌含量在货架期内为106~108CFU/g。旨在加强对国内市场上现有益生菌酸奶产品的分析,本实验为国内首次对益生菌酸奶产品中益生菌菌种的应用状况进行分析,为益生菌酸奶的研发提供参考。 相似文献

Skin is the largest organ of the body and is constantly exposed to physical, chemical, bacterial, and fungal challenges. It is well known that probiotics are helpful for specific disorders and different clinical studies have indicated that probiotics have special effects in cutaneous apparatus directly or indirectly that can be considerable from versatile aspects. Probiotic bacteriotherapy can have great potential in preventing and treating the skin diseases including eczema, atopic dermatitis, acne, and allergic inflammation or in skin hypersensitivity, UV-induced skin damage, wound protection, and as a cosmetic product. The current paper comprehensively reviews the different health effects of probiotics on the skin. 相似文献

During the last 2–3 decades, attempts for improving the human health status, are focusing on ways for modulating the indigenous intestinal flora by live microbial adjuncts, now called “probiotics”. Comprising ca. 65% of the functional food world market, probiotics represent the major and still growing segment of this huge market, estimated to exceed a total volume of US $ 75 billion. The most typical active components of probiotic products are lactic acid bacteria, including bifidobacteria, lactobacilli and enterococci. Health claims related to probiotics are numerous, but include maintenance of normal/healthy intestinal flora and protection against infections, alleviation of lactose intolerance, and stimulation of the immune system. Strains with proven beneficial effects may be consumed in relatively high numbers in products, and are collectively called probiotics. In addition. bifidobacteria and lactobacilli, typical inhabitants of the human GIT, are considered beneficial, and may be stimulated by non-digestible food ingredients such as oligosaccharides, collectively called prebiotics. Probably aimed at the two “target regions” of the GIT, pre- and probiotics may be combined in a food product, called a synbiotic. Confirmed health claims are discussed and reference will be made to open questions and research challenges. 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

欧洲功能性食品的市场及销售情况 总被引:7,自引:0,他引:7
功能性食品的全球市场总额大约有33亿美元,欧洲市场大约有2亿美元,占欧洲食品市场交易额的不到1%。1999年,欧洲功能性日常食品的关键产品销售额大约为1.35亿美元。不少跨国食品公司的利润随着功能食品销售量的增长而增加。一小部分小型和中型公司在夹缝中生存或走仿制之路。营养学研究表明,功能性食品若要具有长期成功的市场必须依赖于产品的开发和销售。一般市场成功的因素(可口、便利、多样)在功能性食品销售中也有重要的作用。 相似文献
