Owing to variations in protein content between human, cow, and goat milks, infant formula was formulated to be as similar as possible to human milk. In this study, goat and cow milk infant formulas were prepared by adding α-lactalbumin and it was directly compared to commercial infant formula protein digestion using growing rats. The nutritional value of these formulated diets was evaluated by estimating their proximate composition, the protein efficiency ratio (PER), corrected protein efficiency ratio (CPER), net protein ratio (NPR). The composition of the formulated diets indicated that satisfied legal nutrient content regulation and are within the range of recommended standards. The PER, CPER and NPR of formulated diets did not significantly (P>0.05) different and much closed to those of control. It was observed no significant difference due to milk type in the quality of protein. The protein quality of the formulated goat and cow infant formula were well comparable with those of commercial infant formula, the common infant diet over the world.","PeriodicalId":15746,"journal":{"name":"Journal of Food and Dairy Sciences","volume":"55 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78784530","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}

According to TEM and Zetasizer analysis, the size of Ch-SeNPs produced in the present study were ranged from 18 to 55 nm with average of 22 nm. Acrylamide treatment led to elevation of the studied biochemical parameters of liver including total protein, albumin, globulin, alkaline phosphatase, aspartate aminotransferase and alanine aminotransferase. Intake of Ch-SeNPs either 15 days prior to or simultaneously with the treatment with acrylamide led to enhance the biochemical parameters to be near the normal range. Same trend was obtained when rats were fed on sodium selenite, but Ch-SeNPs were more closely related to control group (untreated). The histopathological structure examination of rat liver emphasized the obtained biochemical results.The obtained results confirmed that, the intake of Ch-SeNPs 15 days before treatment by acrylamide had significant (< 0.05) protective effect against liver injury compared to the intake of these nanoparticles along with acrylamide.","PeriodicalId":15746,"journal":{"name":"Journal of Food and Dairy Sciences","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75357147","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}
