Abstract: The sausage has a unique flavor and a long history of production. It is a popular meat product. Because sausages are rich in protein, fat and other ingredients, the storage conditions are more demanding. At present, sausages on the market are often in soft plastic packaging. According to the soft plastic packaging of sausages, this article describes the current product standards that can be referenced for sausage packaging. In combination with the product characteristics of sausages, it is proposed that the daily control of sausage packaging quality should be The performance of the key monitoring and the corresponding inspection indicators have certain reference value for the purchase of packaging materials for sausages and similar products, the admission of packaging materials, and the daily packaging quality monitoring.

Sausage is made by grounding the meat of livestock and poultry and other animals into the casing membrane. Its production history can be traced back to about the period of the Southern and Northern Dynasties. It is an ancient meat preservation technology. The content of protein, fat, vitamins, etc. in sausages is high, and there should be good preservation conditions. With the rapid development of modern transportation and transportation technologies, the sales and consumption of specialty foods in different parts of the country are no longer confined to local production. Instead, they are characterized by longer circulation and wider distribution. Sausages are no exception. The packaging technology and packaging materials put forward higher requirements. If the performance of sausage packaging materials is poor, it is easy to increase the packaging, bagging, and mouldiness of sausages during the transportation, sales, and even production of sausages. Therefore, the improvement of quality monitoring of packaging materials will reduce the quality of sausages. The probability has an important role.

1 , the standard situation
At present, the common sausage packaging materials in the market are plastic composite film soft plastic packaging. The product standards that can be referenced in such packaging include:
GB / T 10004-2008 "plastic composite packaging films, bags dry lamination, extrusion lamination" GB / T 28117-2011 "multilayer coextruded film for food packaging, bags" QB / T 1871-1993 "biaxially stretched Nylon ( BOPA ) / Low Density Polyethylene ( LDPE ) Composite Membrane, Bag" BB/T 0041-2007 "General Rules for Multi-Layer Co- Extrusion Barrier Membrane for Packaging " GB 9687-1988 "Hygienic Standard for Polyethylene Molded Products for Food Packaging" GB 9688-1988 Hygienic Standards for Polypropylene Molded Products for Food Packaging2 , the key quality performance
(1) Barrier properties
Oxygen barrier properties in the environment: If the package material is poor in the oxygen barrier to the environment, it can easily cause the proliferation of residual microorganisms in sausages, resulting in sausages with mildew, bagging, and other quality problems. Oxygen barrier properties of sausage packaging The oxygen permeability of the packaging material can be tested and verified by barrier type testing equipment such as the VAC-V2 differential pressure gas permeation instrument.

(2) Physical and mechanical properties
Sealing performance: If the sealing performance of the package is poor, the gas in the external environment will penetrate the inside of the package, reducing the effect of the vacuum packaging on the quality of the sausage, causing the oxidative deterioration of the sausage, and the problem of rising bags. It can be verified by two indicators : heat seal strength performance and sealing performance ( negative pressure method ) of package materials . The related test instruments are XLW(M) intelligent electronic tensile testing machine and MFY-01 sealing testing device .

Flexibility: To prevent package material from poor flexibility, affecting the vacuum effect of packaging. Can, anti Charpy impact energy test was carried out by elongation and tensile elastic modulus-validation, testing equipment respectively associated XLW (M) intelligent electronic tensile testing machine, FIT-01 Film impact tester. Smoothness: Prevents slippage of package materials, resulting in problems such as slipping during pumping, unsmooth drawing, or difficulty opening when filling the contents. Smoothness of sausage packaging The MXD-02 coefficient of friction tester can be used to verify the friction coefficient of the packaging material. Thickness uniformity: verified by a thickness test to prevent material properties from affecting the properties of the package. Can use CHY-CB thickness gauge for testing.

(3) Sanitary performance
Residual amount of organic solvent: For dry composite film packaging or printed packaging, if there is a large amount of residual organic solvent in the packaging, the residual organic solvent will slowly penetrate the sausage during the long-term contact with the sausage, resulting in sausage production. Odor, and affect the health of consumers. It can be verified by residual solvent test. The relevant test instrument is GC-7800 gas chromatograph.To strengthen the daily monitoring of packaging quality and strictly control the quality of packaging materials can effectively prevent sausage quality problems caused by poor package quality or poor compatibility between the use of packaging materials and packaged sausages.
