The results showed that the Sids-40 cultivar was the highest yield, bulb weight, and bulb diameter after curing. Also, Chinese and Sids-40 cultivars achieved the highest values of cloves weight/ bulb. While Balady cultivar was recorded the highest values of cloves number. Balady cultivar was scored lower values of sprouting and decay percentages than Chinese and Sids-40 cultivars. The chemical analysis of different garlic cultivars, edible coating treatments, and different cold storage periods were studied. The obtained results were indicated that the Chinese cultivar had the highest moisture content followed by the Sids-40 cultivar. While the lowest moisture content was recorded by Balady cultivar, meanwhile, it was recorded the highest amount of carbohydrate, fat, and ash, respectively. On the other hand, Sids-40 had the highest value of protein content. According to the results of garlic cultivars, combined with the effects of different cold storage periods and edible coating treatmentsmaintained quality attributes and shelf life of peeled garlic cloves compared with the control sample. Based on our results, some of the functional compounds of garlic were also influenced by storage period, garlic cultivars, and edible coating treatments and they had a positive effect on the keeping of all physicochemical and microbial quality parameters for a longer storage period reached to 270 days. It was noticed that treatment No. (3) was the most effective treatment until the end of cold storage periods for all garlic cultivars especially, Balady cultivar. Moreover, results suggested that the treatment (Chitosan + Carrageenan in addition to potassium sorbate) at cold storage conditions could be a promising treatment for extending the storage period and maintaining postharvest quality of peeled garlic cloves especially, for Balady and Sids-40 cultivars.","PeriodicalId":90815,"journal":{"name":"Current science international","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69657496","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}
