中文摘要: 以猪里脊肉为原料,分别接种0.02%商业发酵剂THM-17(木糖葡萄球菌、戊糖片球菌)、VHI-41(木糖葡萄球菌、戊糖片球菌、植物乳杆菌)、PROMIX-5(木糖葡萄球菌、类植物乳杆菌、清酒乳杆菌)和WBX-43(木糖葡萄球菌、肉葡萄球菌)制成4组猪肉脯,以未发酵型猪肉脯为对照组,采用排序检验法对样品进行感官评定并测定其pH值、红度值a*、水分活度和水分含量,筛选适宜生产发酵猪肉脯的发酵剂。结果表明,发酵能够显著影响猪肉脯的pH值进而影响其组织状态、色泽和口感,改善产品品质。发酵剂PROMIX-5制成的产品组织状态最好,WBX-43和PROMIX-5促进产品发色作用效果,红度值达到22和25,VHI-41制成的猪肉脯pH值最低(4.8),不适宜用于生产猪肉脯。添加0.02%发酵剂WBX-43或PROMIX-5制成的猪肉脯在外观、风味和色泽方面均优于传统工艺猪肉脯。
Abstract:Dried minced pork slices were made from pork tenderloin by four kinds of commercial fermentation agents,included 0.02% THM-17 (Staphylococcus xylose,Pentose phosphate),VHI-41(Staphylococcus xylose,Pentose phosphate,Lactobacillus plantarum),PROMIX-5 (Staphylococcus xylose,Lactobacillus paraplantarum,Lactobacillus sake)and WBX-43(Staphylococcus xylose,Staphylococcus aureus),and the dried minced pork slices were made as control group without any fermentation.The sensory evaluation of the samples was carried out by sequencing test,and the pH values,redness values a*,water activity and water content were determined.The results showed that the fermentation could significantly affect the pH value of dried minced pork slices,and further affect its tissue state,color and taste.The fermentation could significantly improve product quality.The tissue state of the product made from the fermentation agent PROMIX-5 was the best.WBX-43 and PROMIX-5 could promote the effect of product color,and the redness value reached 22 and 25,and the pH value of dried minced pork slices made from VHI-41 was the lowest(4.8),which was not suitable for the production of dried minced pork slices.In this study,the appearance,flavor and color of dried minced pork slices made by adding 0.02% fermenting agent WBX-43 or PROMIX-5 were better than those of traditional dried minced pork slices.
