Aplikasi Edible Coating Lidah Buaya (Aloe Vera L.) Dengan Penambahan Karagenan Terhadap Kualitas Buah Jambu Biji (Psidium Guajava L.)

Edible coating application serves to replace a layer of natural waxes lost due to post harvest handling. This study aims to determine the effect of concentration of carrageenan in edible coating solution of aloe vera on the quality of guava fruit during storage. This study used a completely randomized design, which consists of five treatments and three replications. The treatments were K0 (without addition of carrageenan), K1 (addition of carrageenan 0.1%), K2 (addition of carrageenan 0.2%), K3 (addition of carrageenan 0.3%), and K4 (addition of carrageenan 0.4%). Data were analyzed using analysis of variance followed by Duncan's New Multiple Range Test at 5% level. The results of variance showed that the addition of carrageenan concentration added in aloe vera edible coating applied to guava fruit of significantly affected the weight loss, hardness, total dissolved solids, vitamin C, and skin colour of guava fruit, but did not significantly affected the colour of flesh and flavour of guava fruit in hedonic. The best treatment of the parameters tested of guava fruit during storage was the treatment K4 with the addition 0.4% carrageenan. The treatment K4 had weight loss 7.30%, hardness 6.11 kg/f, total soluble solids 3.39obrix, and vitamin C 173.70 mg/100g. Hedonic sensory assessment of the skin colour of guava fruit had value 2.19 (like), colour of guava fruit flesh had value 2.01 (like), and flavour of guava fruit had value 2.10 (like).
