Quality evaluation standard for casing

The evaluation of the quality of the casing is a systematic project. The following "quality evaluation fourteen" can be more reasonable as the basis for the evaluation of inferior quality.
1. The barrier of the casing: the degree of its barrier to oxygen, water vapor and fragrance. Good barrier can provide long shelf-life and shelf life for sausages, avoid the return of sausages during the shelf life, and ensure that the freshness and aroma of sausages are not lost.
2. The structure of the casing is reasonable: the reasonable structural design of the casing can provide an ideal package for the sausage.
3, the strength of coating film: good mechanical strength can meet the requirements of all kinds of filling and typing machine, thus reducing the loss of casing membrane in the process of use.
4, the stability of shrinkage rate: the consistency of the same volume or the same batch of sausage shrinkage rate. If the shrinkage rate fluctuated more or less than that of the general assembly, the same size sausage will not be evenly distributed, which will cause a lot of trouble for boxing and sale.
5, the color uniformity of color casing, uniform color can give the appearance quality of sausage glory luster, its beautiful appearance, can attract the attention of consumers.
6. The opening of the casing is very important to the filling of the sausage. If the opening is not good, the casing and filling of the casing are more difficult, which will directly affect the working efficiency of the operating workers.
7, specifications: refers to the deviation of accuracy of casing diameter and thickness of the fold should be controlled in strict limits, specifications are not allowed to hand will cause the sausage uneven thickness, the thickness deviation is too large will result in performance degradation and sausage bending phenomenon.
8, the transparency of casing film: for transparent casing film, good diaphaneity is very important for high quality sausages. It can make consumers clearly see the meat texture of sausages, attract consumers' desire to buy, and enhance consumers' first impression of products.
9, soft hardness: good feeling will be easy for your use, after filling sausage for strong sensuality, soft mould ham, sausage can make the shape of sharp and smooth. On the other hand, the edges and corners are hard and easy to make the products out of water.
10, coating film brightness: the sausage is very bright and bright on the shelf, and it is very easy to attract customers.
11. The meat stickiness of the coat membrane:
(1) refers to the meat stickiness of the casing film, which can reduce the amount of water in the sausage, and prevent the taste of the sausage.
(2) refers to the degree of adhesion between the layers of the coating film, so that the structure of the casing is stable and the performance is stable.
12, the bonding effect between each layer: refers to the degree of adhesion between the layers of the coating film, so that the structure of the casing is stable and the performance is stable.
13, film roll evenness: reflect the uniformity of the thickness of the coating film, but can give a comprehensive evaluation of the product.
14, packaging seal: the outer package of the casing is tightly sealed on the one hand to prevent the casing from absorbing moisture. The box is sturdy and reliable, preventing the casing from being damaged and keeping the casing under very good protection.
The casing may be the last step of the sausage processing line for the processing of sausage, but it may cause a lot of trouble to ignore the importance of it. In the selection of casing, we must consider comprehensively. On the one hand, we should choose the good quality casing with good price performance, and on the other hand, choose the casing to meet the requirements of the sausage you produce. At the same time, we should pay attention to the use of the method, make the casing play its due role and bring you considerable economic benefits.
