油茶籽粕鸭蛋去污除菌清洗剂应用效果的研究

目的 研究油茶籽粕去污除菌清洗剂的应用效果。方法 分别用人工污染鸭蛋和鲜鸭蛋为试验材料, 采用油茶籽粕鸭蛋去污除菌清洗剂(CX)、氧净洗液(YX)、自来水(SX)进行清洗处理, 比较其白度提高率、重量减轻率、除菌率和蛋新鲜度品质指标, 并以未加清洗处理作为对照(CK), 进行去污除菌效果的评价。 结果 CX清洗人工污染蛋的感官评分(88±3)分、白度提高率(18.59±0.18)%、重量减轻率(0.44±0.03)%, 菌落总数仅有(3.87±0.32) lg CFU/蛋壳(除菌率99%), 其去污除菌效果优于CK和SX清洗。CX清洗鲜鸭蛋, 其白度提高率(14.568±4.309)%, 重量减轻率(0.6112±0.0032)%, 洁蛋清洗水培养物的OD660为0.178±0.0054。清洗后的鸭蛋其保藏期内气室高度、哈夫值单位、蛋黄指数指标均优于YX、SX。结论 本研究所用的油茶籽粕鸭蛋去污除菌清洗剂清洁效果强, 保鲜力度高, 可延长鸭蛋的货架期

Research on application effect of oil tea seed meal duck egg decontamination sterilization cleaning agent

Objective To study on application effect of camellia oleifera seed meal duck egg decontamination sterilization cleaning agent. Methods Artificial contaminated duck eggs and fresh duck eggs were used as experimental materials. Camellia oleifera seed meal duck egg decontamination cleaning agent(CX), oxygen cleaning solution(YX) and tap water(SX) were used for cleaning. The whiteness improvement rate, weight reduction rate, bactericidal rate and egg freshness quality index were compared, and the decontamination effect was evaluated with unwashed treatment as control(CK). Results The sensory score of CX cleaning artificially contaminated eggs was 88±3, the whiteness improvement rate was (18.59±0.18)%, the weight loss rate was (0.44±0.03)%, and the total number of colonies was only (3.87±0.32) lg CFU/egg (99% sterilization rate). Its decontamination and sterilization effect was better than CK and SX cleaning.When fresh duck eggs were cleaned by CX, the whiteness increased by (14.568±4.309)%, the weight loss rate was 0.6112±0.0032%, and the OD660 of egg cleaning water culture was 0.178±0.0054. After cleaned by CX, the height of air chamber, Huff unit and egg yolk index of duck eggs were better than those of YX, SX during the preservation period. Conclusion The cleaning agent for cleaning duck eggs with Camellia oleifera seed meal has strong cleaning effect and high freshness, which can prolong the shelf life of duck eggs.
