荷斯坦牛奶和水牛奶不同配比对奶酪品质的影响

Effects of Different Proportions of Holstein Milk and Buffalo Milk on Cheese Quality

[目的]我国奶酪行业发展迅速,但奶酪仍存在成本较高、不能满足消费者口味等问题。[方法]本研究将荷斯坦牛奶和水牛奶按适当比例混合制作营养价值更高、口感更好、成本更低的奶酪,为相关产业开发新产品提供参考。试验将荷斯坦牛奶和水牛奶按1︰0(对照组)、9︰1、7︰1、5︰1、3︰1配比混合制作马苏里拉奶酪,测定产率、进行奶酪感官评价。[结果]荷斯坦牛奶和水牛奶配比为3︰1时口感、气味、滋味、弹性、色泽均显著低于其他组奶酪,荷斯坦牛奶和水牛奶配比为1︰0、9︰1、7︰1的奶酪之间无显著差异。荷斯坦牛奶和水牛奶配比为5︰1的奶酪产率显著高于其他组(P<0.05)。荷斯坦牛奶和水牛奶配比为1︰0、3︰1时奶酪成本显著高于其他组(P<0.05)。[结论]荷斯坦牛奶和水牛奶配比为5︰1时奶酪最适宜,具有高产率、低成本优点,为畜产品加工提供新思路。

[Objective]China's cheese industry is developing rapidly,but cheese still has some problems,such as high cost and can't meet the taste of consumers.[Methods]In this study,Holstein milk and buffalo milk were mixed in appropriate proportion to produce cheese with higher nutritional value,better taste and lower cost,which provided reference for related industries to develop new products.Mozzarella cheese was made by mixing Holstein milk and buffalo milk according to 1:0(control group),9:1,7:1,5:1,3:1 ratio.The yield was determined and the cheese sensory evaluation was conducted.[Result]The taste,odor,taste,elasticity and color of Holstein milk and buffalo milk with the ratio of 3:1 was significantly lower than those of other groups,but there was no significant difference between Holstein milk and buffalo milk with the ratio of 1:0,9:1 and 7:1.The cheese yield of Holstein milk and buffalo milk ratio 5:1 was significantly higher than that of other groups(P<0.05).When the ratio of Holstein milk and buffalo milk was 1:0 and 3:1,the cheese cost was significantly higher than that of other groups(P<0.05).[Conclusion]Cheese is most suitable when the ratio of Holstein milk and buffalo milk is 5:1,which has the advantages of high yield and low cost,providing a new idea for livestock product processing.
