牛初乳粉关键品质指标比较分析

Comparative Analysis of Key Quality Index in Bovine Colostrums Powder

对4种牛初乳粉的关键品质指标进行分析。结果表明:实验采集的3种市售牛初乳粉的关键品质指标均达到RHB602—2005《牛初乳粉行业标准》,S2号样品脂肪含量略超标。经含量测定与其产品的标签标示相比,除S2号样免疫球蛋白IgG含量有些差异外,其余均与标签标注相符。本研究自制的初乳粉IgG含量达到44.94%,远高于市售的初乳粉。

In this study, key quality index in four kinds of bovine colostrums powder from markets were analyzed.
