Cocoa Black Tea Flavor Protein Bar Satiety and Storage Period Accelerated Experimental Research
A high protein cocoa black tea-flavored protein bar with various high-quality proteins was used as the research object to test its satiety and shelf stability.The results showed that the overall satiety trend was similar,and the peak of satiety was reached at 30 min.The scores of the three indicators were consistent among women,and eating cocoa black tea flavored protein bars on an empty stomach could maintain a sense of satiety for 3.5 hours,which was better than that of white bread,while the scores of men on the three indicators were different,which may be related to body mass index,eating habits and other factors,but all showed that the feeling of satiety was better than that of white bread at 1.5 hours and 2 hours.The shelf-life stability test used the ASLT method to accelerate the shelf-life test to predict the shelf-life of protein bars.Under the conditions of 40 ℃,50 ℃ and 75％relative humidity,the shelf life was predicted by sensory indicators.The results showed that the sensory evaluation index of protein bars was acceptable when stored at 40 ℃ and 75％relative humidity for 80 days and 50 ℃ and 75％relative humidity for 25 days,and it was inferred that the shelflife of the product was about 15 months under the storage conditions of 25 ℃.
