The Saskatoon Colostrum Company Ltd. (SCCL) plans to develop a shelf-stable liquid colostrum product that will be used to supplement or replace maternal colostrum for newborn calves. Significant challenges are microbial contamination and physical separation of the cream and protein rich phases upon storage. While the problem with microbes can be addressed by irradiation, the proposed research proposal will investigate the feasibility of producing a stable dispersion of colostrum with a minimum shelf life (no phase separation) of 1 year at room temperature. In the proposed project, colostrum phase separation will be prevented by developing a highly stable dispersion with extremely small fat globules. Liquid colostrum will be mixed with small molecule emulsifiers (SME) and subjected to high-pressure homogenization. The SME will reduce the

萨斯卡通初乳有限公司（SCCL）计划开发一种货架稳定的液体初乳产品，用于补充或替代新生小牛的母体初乳。显著的挑战是微生物污染和储存时奶油和富含蛋白质的相的物理分离。虽然微生物的问题可以通过辐照来解决，但拟议的研究提案将研究在室温下生产稳定的初乳分散体的可行性，其最低保质期（无相分离）为1年。在拟议的项目中，将通过开发具有极小脂肪球的高度稳定的分散体来防止初乳相分离。将液体初乳与小分子乳化剂（SME）混合，并进行高压均质。中小企业将减少
