  • Publication number: 20200399831
    Abstract: Disclosed in one aspect is a pickled vegetable-based edible packaging paper, the raw material of which is composed of the following components in parts by weight: 92-95 parts of a high dietary fiber-level pickled vegetable, a compounding thickener (0.6-0.8 parts of pectin, 0.6-0.8 parts of potato starch, and 0.2-0.4 parts of soy protein), and a compounding plasticizer (3-4 parts of sorbitol, and 0.5-1.5 parts of citral); and further disclosed in another aspect is a method for preparing a pickled vegetable-based edible packaging paper. The pickled vegetable paper of the present invention is a novel pickled vegetable-based product having both edible and practical functions, which product is rich in dietary fibers, retains the unique flavor and color of the pickled vegetable, has toughness and non-stickiness to teeth, and is soft and easy to process after being wetted.

  • Patent number: 10781165
    Abstract: Disclosed are a pH-responsive amphoteric surfactant N-lauryl-(?-alkyl)-?-aminopropionic acid and a preparation method and uses thereof. An alkylamine and a solvent are added to a three-necked flask, stirred for complete dissolution, slowly dropwise added with methyl ?-alkyl-acrylate and reacted at room temperature after the ice-water bath is removed. The reaction mixture is refluxed in water bath and evaporated under rotation to remove the solvent and the residual methyl ?-alkyl-acrylate to give N-lauryl-(?-alkyl)-?-aminopropionic acid. Then N-lauryl-(?-alkyl)-?-aminopropionic acid and water are added to a three-necked flask, slowly dropwise added with a sodium hydroxide solution and reacted in water bath to give a crude product, which is filtered and dried to give a purified surfactant sodium N-lauryl-(?-alkyl)-?-aminopropionate. This surfactant is suitable for the foamed acid system and its performance can be switched by adjusting pH due to pH sensitivity.
