驴奶的消费广度和知名度与牛奶相比都比较低。但驴奶营养成分丰富,含有溶菌酶、多不饱和脂肪酸和矿物质元素硒等多种生物活性成分,因而具有多种生物活性和丰富的有益健康功能,例如低过敏性、抗菌活性、免疫调节活性和抗炎作用等。本文分析和讨论了驴奶中的化学成分的种类和含量,并总结了近几年关于驴奶功效的研究进展,以期能够为驴奶将来的研究方向和内容提供科学依据。 相似文献

鲜驴奶的保健功效研究 总被引:3,自引:0,他引:3
目的:研究鲜驴奶对小鼠免疫功能的影响;及鲜驴奶体外抑制结核杆菌生长作用.方法:应用环磷酰胺制备免疫低下小鼠模型,以不同剂量鲜驴奶作为受试物灌胃20d,研究鲜驴奶对小鼠脾脏及胸腺指数、抗体分泌细胞功能、血清溶血素水平、脾脏淋巴细胞转化功能等免疫指标的影响;按照<结核病诊断细菌学检验规程>以覆盖法研究鲜驴奶体外抑制结核杆菌生长作用.结果:鲜驴奶高剂量组可以增加血清溶血素含量并可提高小鼠脾细胞抗体分泌细胞功能;大剂量 (0.4、0.5ml)驴奶脂肪抑菌效果明显.结论:鲜驴奶对免疫力低下小鼠的免疫功能具有一定的增强作用;鲜驴奶脂肪在体外具有抑制结核杆菌生长的作用. 相似文献

本研究建立了一种基于内参基因的标准化实时聚合酶链式反应(real-time PCR)方法,能够定量检测混合掺假的灭菌乳中驴奶的含量。使用单拷贝核基因代替多拷贝线粒体基因,基于Ct值(驴特异性引物/内参引物)与驴奶含量的线性关系,对含量为5%~100% 的驴奶建立了标准曲线。该方法具有良好的线性相关(R2=0.9650)和较高的准确度,对含有20%、50%和80% 驴奶的模拟掺假样品进行定量分析,平均回收率为109.16%,平均CV值为4.68%。因此,该方法可以快速、准确地对驴奶进行定量,从而确定驴奶是否掺假以及掺假比例。

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

This paper presents the combined mid-term findings of the consumer research components of two EU Sixth Framework Programme integrated projects concerning meat, ProSafeBeef and Q-PorkChains. The consumer pillar of ProSafeBeef carried out eight focus group discussions in May 2008, in France, Germany, Spain and the UK. Q-PorkChains conducted a large-scale, web-based, consumer survey in January 2008 in Belgium, Denmark, Germany, Greece and Poland. The first project provides a set of qualitative data from a small cohort of focus groups and the second a set of quantitative data from a larger consumer sample. This paper draws together the main findings of both projects and provides a comprehensive overview of European citizens’ and consumers’ attitudes towards and preferences regarding beef and pork. In general, consumers consider meat to be a healthy and important component of the diet. Consumers support the development of technologies that can improve the health attributes of meat products and guarantee eating quality, but they have a negative view of what they see to be excessive manipulation and lack of naturalness in the production and processing of beef products. In the Q-PorkChains study consumer and citizen segments are identified and profiled. Consumer segments were built upon the frequency and variety of pork consumption. The citizen segments were built upon their attitudes towards pig production systems. Overall, the relationship between individuals’ views as citizens and their behaviour as consumers was found to be quite weak and did not appear to greatly or systematically influence meat-buying habits. Future studies in both projects will concentrate on consumers’ acceptance of innovative meat product concepts and products, with the aim of boosting consumer trust and invigorating the European beef and pork industries. 相似文献
