热激修饰瑞士乳杆菌对Cheddar干酪成熟的影响（Effects of Heat-shock Lactobacillus helveticus on Cheddar Cheese Ripening）
热激 修饰性菌株 瑞士乳杆菌
2009/11/3
研究了瑞士乳杆菌Lactobacillus helveticus6024经热激修饰后，与干酪成熟相关的生化性质变化及其对Cheddar干酪成熟的影响。结果表明：瑞士乳杆菌经70℃、10 s的热激处理后，在10%脱脂乳中经32℃、6 h培养后，其产酸能力仅为6.4%，而与干酪成熟密切相关的平均氨肽酶活力，仍有约25%的保留。热激处理后的菌株加入到干酪中对其组分没有显著影响，但对干酪可溶氮水平有不...
