| 摘 要： | 对不同品种水牛乳进行为期一年的随机抽样测定,分析水牛乳冰点值与季节以及各主要理化性质间的相关性。结果表明,尼里-拉菲水牛乳一年中冰点均值范围为-0.536~-0.528℃之间;麽拉水牛乳为-0.537~-0.528℃之间;三品种杂交水牛乳为-0.543~-0.531℃之间;一代杂交水牛乳为-0.548~-0.533℃之间,各品种水牛乳冰点均值最低值出现在7、8月份,水牛乳的冰点值与水牛乳滴定酸度、蛋白质、脂肪、总固形物、乳糖+灰分总量存在Pearson极显著负相关性(p<0.01),与水牛乳水分含量存在Pearson极显著正相关性(p<0.01),与水牛乳中的体细胞数无显著相关性(p>0.05)。

| Abstract: | Buffalo milk was randomly sampled for a year to study the correlation between freezing point and physic-chemical properties. The results showed that the average range of freezing point value of four breeds buffalo milk was found,the nili-ravi was -0.536~-0.528℃,murrah was -0.537~-0.528℃,three-way cross breed was -0.543~-0.531℃,two-way first filial generation was-0.548~-0.533℃. Freezing point value was the lowest in July and August in a year. The significant negative correlation was found between acidity,protein,fat,total solids,totle content of lactose with ash and freezing point value(p<0.01),significant positive correlation was found between moisture and freezing point value(p<0.01),no significant correlation between somatic cells count and freezing point(p>0.05). |
