In addition, the study will also conduct sensory tests of color, suppleness and aroma. This research method applies a factorial Complete Randomized Design (RAL) involving two main factors. The first factor is the concentration of basil extract solution (K), which has three levels (K1:10%, K2:20%, and K3:30%). The second factor is the duration of immersion (L), which also has three levels (L1: 30 minutes, L2: 60 minutes, and L3: 90 minutes). Each variation of the treatment was repeated three times, and tests were carried out on formalin content, protein levels, and sensory tests covering aspects such as color, texture, and aroma.

One effective approach to maintain product quality is by using edible coating, and in this case, alginate-based edible coating has been employed. The alginate-based edible coating exhibits a deficiency in terms of its inadequate mechanical properties. The addition of starch could improve the mechanical properties of alginate-based edible coating. Jackfruit seed starch has the potential to valorize as a cost-effective source of starch. Jackfruit seed flour has unique starch characteristics related to acid resistance, thermal properties, and mechanical properties when compared with starch from other sources. This study aims to optimize the concentration of alginate and jackfruit seed flour in the preparation of tomato edible coating using Response Surface Methodology (RSM). The effect of alginate concentration (1-2% b/v) and jackfruit seed flour concentration (1-2% b/v) on mass loss (%) and color difference (ΔE) were investigated. The optimum condition was obtained at an alginate concentration of 1.5% b/v and jackfruit seed flour concentration of 1.0% b/v with the resulting tomato quality value of mass loss of 5.43% and color difference (ΔE) of 0.70.","PeriodicalId":511781,"journal":{"name":"Jurnal Teknologi Hasil Pertanian","volume":" 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141129908","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}
