Food additive polyvinyl alcohol detection

Polyvinyl alcohol is an organic compound with good mechanical properties (such as adhesion, water solubility, film-forming properties, emulsifying properties), as well as excellent chemical resistance (such as oil resistance, solvent resistance, etc.). It is commonly used in the manufacturing of polyvinyl acetals, gasoline resistant pipelines, and vinylon synthetic fibers, fabric treatment agents, emulsifiers, paper coatings, adhesives, adhesives, and adhesives

Plastic polyvinyl alcohol material testing:

Plastic polyvinyl alcohol material testing can mainly be carried out in accordance with the GB/T 12010-2008 series of standards. There are a total of 8 standards in the GB/T 12010-2008 series, which mainly regulate the performance testing of plastic polyvinyl alcohol materials. The performance testing items of plastic polyvinyl alcohol materials mainly include volatile content, sodium acetate content, ash content, viscosity, pH value, particle size, sodium hydroxide content, average degree of polymerization, transparency, etc

Testing of polyvinyl alcohol as a food additive:

As a food additive, polyvinyl alcohol can be tested according to the mandatory national standard GB 31630-2014 "National Food Safety Standard for Food Additives - polyvinyl alcohol". The testing items specified in GB 31630-2014 mainly include color, state, drying loss, burning residue, water insoluble substances, particle size, methanol and methyl acetate, acid value, hydrolysis degree, esterification value, viscosity, lead content, etc
