One collagenase (CLS1^®) and two proteases (Proleather FG-F^® and Protease N^®) were used to deskin the peritoneal membrane of catfish nuggets. The factors were used in a full factorial experiment design: enzyme solution concentration (0.2, 0.3, and 0.4% by weight), temperature of enzyme solution (30, 37, and 44°C), and immersion time (10, 15, and 20 min). Contour plots showed that the enzyme Proleather FG-F^® maximized whiteness of catfish nuggets at 40–44°C for 15–19 min. Treatment of the enzyme Proleather FG-F^® at 0.2% for 15 min had the highest yield (103.4%) at 44°C. Enzymatic skinning has potential in removing the peritoneal membrane from catfish nuggets, improving color (whiteness), and yield.  相似文献

石油价格的不断上涨,给花卉生产者在冬季的生产增加了相当大的成本。为了降低燃油成本而获得最大的利润,他们只能尽量降低温室内的温度,但是,温度降低后对于花卉的生长、发育的影响却少有研究。前几年,美国密歇根州立大学的有关人员开始研究温度和光照对广泛应用的四种花坛花卉  相似文献
