PEMANFAATAN GLISEROL DAN PATI SAGU SEBAGAI EDIBLE COATING PADA PENYIMPANAN JERUK SIAM MADU (Citrus nobilis)

Abstract

This study aims to determine the effect of adding glycerol and sago starch as edible coating on the quality of honey citrus fruits during storage and to determine the quality and freshness quality of siamese citrus honey after the addition of glycerol and sago starch as edible coatings on the quality of honey siam during storage . This study used a non-factorial Completely Randomized Design (RAL) arranged in factorial with 2 factors. Factor I: Comparison of glycerol, sago starch and distilled water. G0 = 0 ml glycerol concentration (control) + sago starch 10 gram + 500 ml distilled water, G1 = glycerol concentration 2ml + sago starch 10 gram + 500 ml distilled water, G2 = 4 ml glycerol concentration + sago starch 10 gram + aquades 500 ml, G3 = 6 ml glycerol + sago starch concentration 10 gram + 500 ml distilled water, G4 = 8 ml glycerol concentration + 10 sago starch + 500 ml distilled water. Factor II: Duration of storage (days). H0 = 0 days, H1 = 3 days, H2 = 6 days, H3 = 9 days, H4 = 12 days, H5 = 15 days. The results showed that the concentration of glycerol and starch of sago as edible coating on the quality of citrus honey during storage was significantly different from the weight loss with the concentration of glycerol = 8 ml at storage (15 days) which was 0.27%; and followed by Vitamin C significantly different from storage (12 days) with glycerol concentration = 0.06%, then total different acids were not significant at storage (15 days) with 0.02% glycerol concentration and different colors not significant with 1 ml glycerol concentration on storage (6 days) which is = 4.00%.

Effect of Formulation of Edible Coating Solution on Weight Loss of Kaempferia Galanga Peeled Tubers

“…Other researchers using lower glycerol, which is less than 2 %, reported that there was no effect of using edible coating in protecting the product from weight loss. This study differs from the results reported on the use of glycerol in edible films where it was reported that increasing the concentration of glycerol had no significant effect on the value of the water vapor transmission rate of edible films (Prasetyo & Laia, 2018). The low concentration of glycerol in the edible film is not effective in inhibiting the rate of water vapor transmission from the product.…”

Pengaruh Kitosan Sebagai Edible Coating Terhadap Mutu Fisik Dan Kimia Jeruk Rimau Gerga Lebong Selama Penyimpanan

“…Menurut Prasetyo & Laia (2018), peningkatan susut bobot disebabkan karena beberapa faktor seperti kehilangan gas CO2 hasil respirasi, sehingga buah mengalami kerusakan yang diakibatkan kehilangan air pada buah jeruk tanpa perlakuan, sehingga susut bobot dari hari ke hari semakin tinggi. Gardjito & Swasti (2014) juga menjelaskan bahwa proses transpirasi dapat menurunkan kualitas buah dengan terjadinya penurunan berat.…”
