The safety of cereal-based baked goods can be compromised by acrylamide, a processing contaminant and class 2A carcinogen. One method to prevent acrylamide formation is by converting asparagine to aspartic acid using asparaginases. Four different asparaginases were tested using two dough incubation temperatures and dosages for oat, corn, and rice cookies. To evaluate the impact of asparaginases on product quality, color and texture were measured. Acrylamide was reduced by up to 97, 95, and 92% for oat, corn, and rice cookies, respectively, compared to the control. Asparaginase treatment resulted in minor changes in color and texture. There was a strong correlation between acrylamide concentrations in cookies and the free asparagine content of the flour. By minimizing the formation of acrylamide while maintaining product quality, the use of asparaginases offers a promising approach to enhancing food safety standards and protecting public health, potentially influencing regulatory guidelines and consumer preferences.
基于谷物的烘焙食品的安全性可能会受到丙烯酰胺的影响,丙烯酰胺是一种加工污染物和2A类致癌物。一种防止丙烯酰胺形成的方法是使用天冬酰胺酶将天冬酰胺转化为天冬氨酸。使用两种面团孵育温度和剂量,对燕麦、玉米和米饼干测试了四种不同的天冬酰胺酶。为了评估天冬酰胺酶对产品质量的影响,测量了颜色和质地。与对照相比,燕麦、玉米和米饼干中的丙烯酰胺分别减少了高达97%、95%和92%。天冬酰胺酶处理导致颜色和质地有轻微变化。饼干中的丙烯酰胺浓度与面粉中的游离天冬酰胺含量之间存在很强的相关性。通过在保持产品质量的同时尽量减少丙烯酰胺的形成,使用天冬酰胺酶为提高食品安全标准和保护公众健康提供了一种有前景的方法,可能会影响监管指南和消费者偏好。
