Abstract:

In order to improve the utilization rate of crab by-products, reduce environmental pollution, and enrich the source of calcium intake in human body, crab shell powder was added in the sausage production process. Firstly, the single factor experiment was conducted to investigate the effects of the addition mass fraction of white pepper, crab shell powder, corn starch and salt on the sensory scores of the sausage. Then, the response surface experiment was conducted to determine the optimal formulation of the crab flavor sausage. Finally, the difference in quality between the added and unadded crab shell powder was investigated in terms of sensory scores, texture, color, moisture, protein, fat, calcium, flavor (odor, taste), and digestibility. The results showed that the best sensory score was obtained with the addition mass fraction of 0.5% white pepper, 2.1% crab shell powder, 5.8% corn starch and 1.7% salt. After the addition of crab shell powder, the a*value and b* value of the sausage increased, and the hardness and chewiness increased, indicating that the addition of crab shell powder could effectively improve the color and texture of the sausage; the calcium content, DPPH radical scavenging rate, ABTS+radical scavenging rate, and Fe2+ chelating rate were 4.99, 2.14, 1.78, and 1.86 times higher than those of the sausage without the addition of crab shell powder, respectively, indicating that the addition of crab shell powder could enhance the calcium content and the antioxidant ability effectively. The E-nose and E-tongue showed that the crab shell powder had the effect of giving unique odor and taste to the sausage, and the digestion simulation tests of the stomach and small intestine showed that the addition of crab shell powder had no obvious effect on the digestibility. In conclusion, the crab flavor sausage improves the sensory and nutritional value of the product, gives a unique flavor, improves the utilization rate of crab by-products, and has a good market prospect.
