As the levels of chitosan, propylene glycol-1,2 and glycerol increased, the hardness, consistency and cohesiveness of the hydrophilic gels increased, while the dissipation capacity decreased. Gels based on methylcellulose and chitosan, compared to formulations containing polyvinylpyrrolidone, have a higher rate of loss of volatile compounds, higher pH values for 1,2-propylene glycol formulation and higher texture parameters. The tested hydrogels have good rheological properties, allowing extrusion from the tube and spreading on the skin.","PeriodicalId":44461,"journal":{"name":"Progress on Chemistry and Application of Chitin and its Derivatives","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2018-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46659345","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dependences on the change of moisture and fat-retaining power (MRP, FRP) and effective viscosity (η) on the above-mentioned parameters were investigated.\u0000The parameters of micronising were validated: the speed of rotation of the knives (υ) was 2500 rpm, the processing time (τ) was 60 s, υ was 3000 rpm, and τ was 50 s; also, the mass fraction of chitosan derivatives was 0.06%, which ensures the production of meat-and-vegetable emulsions of high quality.","PeriodicalId":44461,"journal":{"name":"Progress on Chemistry and Application of Chitin and its Derivatives","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2018-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48182590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
