随着消费者购买力的增长，以及消费者选择食品能力的增加，消费者对食品的要求已不仅仅局限于营养的供给。尽管价格对主导消费者选择起决定性作用，但是很多消费者还是乐意多付钱来选购更健康的食品。此外，消费者需要无害的食品。鸡蛋业有更多发展前景，不仅在于营养补充品和功能性食品上，还在于非食用的鸡蛋产品。根据适当的性能判定指标，仔细研究成本和对于生产者与消费者的益处多方面因素，来作出符合经济效益的正确决策。 相似文献

牛奶是深受广大消费者喜爱的一种营养食品之一,营养价值高,易于消化,其中牛奶的乳脂率是评定牛奶质量的重要指标,其乳脂率的高低受到多种因素的影响,其中包括遗传因素、环境因素、营养因素、饲养管理因素以及疾病因素等,提高牛奶的乳脂率是提高牛奶质量,从而提高奶牛养殖经济效益,促进奶牛养殖业蓬勃发展的重要手段。因此,需要分析影响牛奶乳脂率的原因,并采取综合性的措施和方法以提高奶牛乳脂率。 相似文献

A consumer questionnaire conducted with the purpose of ascertaining the acceptability of goat milk and related products in Japan was carried out on 345 guarantees of Nippon Veterinary and Life Science University in December 2006. 275 effective responses (79%) representing middle class urban households were returned. The results revealed that (1) 30% of respondents have experienced drinking goat milk and only 10% are aware of the current retail situation of goat milk and related products; (2) over 70% of goat milk drinkers raised goats by hand at some point in their past and their first experience drinking goat milk was in infancy; (3) those with experience in drinking goat milk expressed a vague evaluation and minimal understanding of drinking goat milk; (4) respondents who were inexperienced goat milk drinkers expressed a strong desire to taste and a weak desire to purchase goat milk; (5) respondents expressed low recognition regarding retailed goat milk products, but those who had already purchased goat milk products expressed a high evaluation and strong desire to purchase these products again; and (6) recognition of goat milk characteristics is low, but those with high recognition also rate goat milk highly. Goats are perceived as being 'mild and familiar.' It is necessary for those who manage goat husbandry to present goat milk and related product tasting opportunities to consumers. The key point is to make the functional differences between cow and goat milk clear and present the advantages of goat milk at the fore of this promotion. Goat milk should not be promoted merely as a drink that is similar to cow milk, but must be positioned as a functional drink or health food in order to expand the Japanese goat milk market. 相似文献

German consumers trust the safety and the quality of milk and milk products. Compared with other animal products, e. g. meat and meat products, their confidence is justified in so far as milk and milk products cause only few foodborne diseases in Germany, although 80 percent of all German cows develop at least one case of mastitis per lactation. Due to financial reasons, more and more German dairy farmers are forced to initiate a time-saving rationalization of their workflow. Therefore, automatic milking systems (AMS) are used increasingly, even though the costs of purchase result in a slow pick-up in sales. Moreover, AMS do not comply with legal requirements. Thus, an additional regular, the so called "catalogue of measures", had to be enacted to ensure the hygienic harmlessness of milk produced by AMS. This is the first time, that udder health at individual cow level was related to milk quality beyond merely clinical signs. Together with technical innovations for an improved health monitoring at cow and herd level as well as the implementation of quality assurance programs based on prevention, this improvement offers good prospects to produce not only a hygienically harmless, but also a physiologically composed milk and therefore a qualitatively high-grade milk from healthy cows. Being the vehicle of the most recent improvements in technology, AMS do have the potential to make a crucial contribution to this development. 相似文献

The udder health of dairy cows is necessary in order to serve the consumer with milk and milk products of perfect quality and sound hygiene. Also in districts where the dairy industry is less developed a better udder health can be obtained when certain hygiene rules are carried out in connection with simple diagnostic and therapeutic measurements. 相似文献

猕猴桃奶豆腐加工工艺及配方研究 总被引：1，自引：0，他引：1
开发一种新型的适合大众口味的高营养奶制品。以山羊奶为主要原料,以适量的猕猴桃汁和白砂糖等作为辅料,通过工艺改进和配方优化,加工一种新型山羊奶制品。得出猕猴桃奶豆腐的加工工艺为:原料乳(制作奶皮子后的脱脂乳)→杀菌→添加发酵剂→自然凝乳→切割→排乳清→升温搅拌→保温搅拌→静置→排乳清→切碎→压榨→成形→冷藏。配方为:鲜羊奶75%,猕猴桃汁17%,白砂糖8%,再加入少量的甜味剂和调味剂。研制的猕猴桃奶豆腐既有羊奶的乳香、猕猴桃的酸甜,同时更富于其更全面的营养物质。 相似文献
