Abstract

Meatballs are processed meat products with a short shelf life because they are easily damaged, which is less than 8 hours at room temperature. To overcome this problem, meatball producers often take an alternative by adding harmful preservatives such as borax and formalin. Technological advances can provide solutions, namely packaging that can be eaten and made from processed products from substitute packaging that is difficult to increase or harm the body, namely edible film. The use of starch-based packaging with the addition of antimicrobial compounds, namely Allicin from chives extract is a good alternative to increase the durability and quality of meatballs during storage.This study aims to reduce the use of plastic packaging and extend the life of meatballs by using edible film packaging. This study used a RAKwhich was composed of 2 factors and each consisted of 3 levels. The first factor was the concentration of cassava starch (1 %, 2 %, and 3 % w/v) while the second factor was the concentration of chives extract (3 %, 5 %, and 7 % v/v) into the edible coating    as an antimicrobial packaging for meatballs. The results showed that the characteristics of theedible film were influenced by the concentration of starch and chives extract. The best meatballs, namely 3 % starch coated meatballs and 7 % chives extract, obtained quality active edible films and increased the shelf life of meatballs at room temperature for 48 hours (6x longer than meatballs without coating ) which are safe for consumers. These results indicate that the application of alicin from chives extract as an edible coating    has a tensile strength value (0.71 MPa), elongation (41.50 %), WVTR (3.65 g/m2/24hours), thickness (0.24 mm), zone of inhibition (3.29 mm), and was effective in controlling the microbiological growth of meatballs.

Abstract

This paper aims to determine the effect of different types of fermentation containers. Fermentation of cocoa beans can be done using several types of fermentation containers such as fermentation boxes, bamboo baskets and styrofoam. Each type of container will produce different types of fermentation containers will influence changes in temperature and pH profiles during the cocoa bean fermentation process.    In this discussion we will discuss the influence of different types of fermentation containers used on the quality of the cocoa beans produced, so that this study can provide information regarding the influence of the type of fermentation container used on the success and quality of the cocoa beans. The method used is to review several previous articles using Google School and draw conclusionsUsing wooden boxes as fermentation media will produce more optimal temperature and pH than other container types because they have insulating properties. The duration of the length of the cocoa bean fermentation process will affect the result of the moisture content of the fermented cocoa beans. The longer the cocoa fermentation process, the lower the dried cocoa beans' moisture content. Limit The maximum moisture content of cocoa beans, according to SNI, is 7.5%. The total phenolic value of fermented cocoa beans is influenced by several differences, namely differences in fruit varieties, fruit maturity levels, fermentation processes, drying, and roasting or roasting.
