Abstract

In Indonesia, grapes (Vitis vinifera L.) are widely planted in lowland areas with production of 11,905 tons per year in 2020 and continues to increase. Grapes that rot easily must be processed into various products even though grapes are not one of the fruit commodities with large production in Indonesia. However, according to 2020 data, Indonesia imported around 70,000 tons of grapes. The content of fresh grapes in 100 grams is 69 kcal energy, 88% water content, 1% fiber, 18.1 grams carbohydrates, 0.72 grams protein, 0.16 grams fat and rich in antioxidants. The abundant content of grapes makes this plant have the potential to be processed into a functional food product, namely grape vinegar. Wine vinegar has been studied to have antioxidant and antimicrobial effects. The purpose of writing this review is to determine differences in fermentation conditions and inoculum concentrations for making wine vinegar. The method used is searching for articles in the form of national and international journals in Google Scholar and ScienceDirect with the keywords inoculum, vinegar, wine and fermentation. The review results obtained show that differences in fermentation conditions (pH, time, oxygen) and inoculum concentration can have an effect on the product. The fermentation conditions are acidic, with oxygen and the length of time is appropriate to the microbes used. The inoculum concentration used is 5-15% or up to 20%. The conclusion of this review is that differences in fermentation conditions and inoculum concentrations in vinegar production have an effect on wine vinegar products.

Abstract

Packaging technology in the form of starch-based edible film has been widely discovered and developed at present, one of which is Edible Film Pati Garut. Arrowroot starch has a starch content of 98.1% and is classified as high. The addition of aloe vera gel is known to inhibit the transfer of CO2 and O2 gases and contains many functional components that are able to inhibit damage to a product so it is hoped that it can improve the physical characteristics of the resulting film. This research aims to determine the effect of adding arrowroot starch and aloe vera gel on the characteristics of edible films, to determine the effect of differences in arrowroot starch concentrations on film characteristics, to determine the effect of differences in aloe vera gel concentrations on film characteristics and to determine the best treatment for adding arrowroot starch concentrations and aloe vera gel concentration on physical characteristics. This research used a factorial Randomized Group Design (RAK) method with 2 factors. The first factor is the concentration of arrowroot starch (A) (4%, 5% and 6%) and the second factor is the concentration of aloe vera gel (B) (3%, 4% and 5%) to obtain 9 treatment combinations with 3 repetitions. . The parameters observed included thickness analysis, transparency. The results of the study showed that there was no interaction between arrowroot starch concentration and aloe vera gel concentration on physical characteristics. The addition of arrowroot starch concentration has a significant effect on the thickness and transparency values. The addition of aloe vera gel concentration has a significant effect on the thickness and transparency values. The best treatment in this study was the A3B3 treatment (6% arrowroot starch concentration and 5% aloe vera gel) with an average value What was obtained was a thickness of 0.17 mm and a transparency of 2.162 (A546 mm).
