1. Good taste, good transparency and simple production process.
2. Highly breathable and moisture permeability. Collagen casing has the ability to'breathe', allowing gas and water to penetrate during the smoking or cooking process without causing the loss of contents. Due to its special structure, the smoked spices can be fully inhaled into the sausage, and its fragrance is preserved in good condition (within the shelf life). The products packed in collagen casings can be fried and will not fall off during storage and cooking.
3. Thermal stability. The protein casing can always maintain the same size of the product during cooling and storage, and there will be no space bubbles, thereby ensuring product quality.
4. Good flexibility. Collagen casing has a certain degree of elasticity and can overfill 5-7% of the content.
5. Aesthetics. First, the natural shrinkage of the protein casing can ensure the smooth and beautiful surface of the sausage; secondly, the use of protein casing during quantitative enema can keep the product appearance neat and beautiful during the enema; third, the use of colored protein casing can improve the appearance of the final product.
