摘要:

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RHB 602 — 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。

Abstract:

In this study, key quality index in four kinds of bovine colostrums powder from markets were analyzed. According to the RHB 602—2005, all tested products were fulfilled the new standard except sample 2 with exceeded fat content. The content indices were well matched with labels except sample 2 with small difference in IgG contents. Bovine colostrums powder from markets was more stable with guaranteed quality. Moreover, the content of IgG in bovine colostrums powder made in our laboratory was 44.94%, which was much more than that in four samples from markets.

Key words: bovine colostrums powder, quality criteria, immunoglobulin concentration
