Long-term refrigeration method of fresh breast milk

The invention discloses a long-term refrigeration method of fresh breast milk, and belongs to the field of food preservation. The method comprises the followings steps: an emulsifying agent is added into the breast milk, and a homogenizing means is adopted to assist the refrigerator in refrigerating the breast milk; the four indexes of the acid odor, the pH value, the titratable acidity and the free fatty acid during the breast milk refrigeration period are respectively determined, and the results show that when the breast milk refrigerated by the method is used for more than 3 days, the fatty acid related indexes are mutated, the deterioration delay rates of all the indexes are more than 40%, and the average delay rate is more than 70%. Therefore, the breast milk refrigeration time can be prolonged to more than 3 days, and a novel method which is simple to operate and low in cost is provided for preservation of fresh breast milk. 本发明公开了一种新鲜母乳的长期冷藏方法，属于食品保鲜领域。本发明向母乳中添加乳化剂并采用均质手段辅助冰箱冷藏母乳。分别测定了母乳冷藏期间酸臭味、pH、可滴定酸
