Abstract

Cocoa is a leading commodity in the Special Region of Yogyakarta that needs to be developed. In Nglanggeran, Patuk, Gunungkidul, stands the Agricultural Technology Park (ATP) based on cocoa comodities that needs to be supported by postharvest technology studies including packaging and storage of cocoa beans to be able to produce quality and safe processed chocolate. The purpose of this study is to find out added value of cocoa beans with and without the addition of Lactobacillus plantarum HL 15 starter and packaging during storage. This research was conducted in January - December 2018 in the Ngudi Raharjo II Farmer Group, Plosokerep, Patuk, Gunung Kidul. The experimental design used was factorial completely randomized design 2 replications, with the first factor being the type of fermented cocoa beans (B), consisting of: fermented cocoa beans with starter L. plantarum HL. 15 (B1) and fermented cocoa beans by farmers (without starter) (B2) and the second factor type of packaging (K), consisting of: PP plastic in vacuum (K1), PP plastic without vacuum (K2) Plastic container (K3), PP plastic + vacuum + plastic container (K4). Nylon sack (farmer control) (K5). The result is an increase in added value from the highest to the lowest is IDR 2,675/kg (K4B1), IDR 2,375/kg (K2B1), IDR 2,025/kg (K1B1), IDR 1,725 /kg (K3B1), IDR 1,350/kg (K3B2) , Rp. 1,100 /kg (K2B2) and (K1B2), Rp. 1,050/kg (K2B2), Rp. 475/kg (K5B1), and Rp. 100/kg (K5B2). Keywords: fermented cocoa beans, added value, packaging

Abstract

Goat's milk has a complete nutritional content, but so far it has not been favored because of goaty flavor which comes from short and medium chain fatty acids such as caproic acid, caprylic acid and capric acid. Processing milk into fermented milk like kefir is one method of processing milk that is useful to increase the nutritional value of milk and eliminate goaty flavor. The aim of this study is to know the effect of the use of kefir granule and sucrose levels on the sensory properties of PE goat’s milk kefir. The ingredients used are PE goat's milk, kefir granules, sucrose, aquadest. The Completely Randomized Design with six treatments is used in this study. Organoleptic test were using a hedonic scale. The treatments were arranged as follows: A1B1 (5% kefir granules 5%, 0% sucrose); A1B2 (5% kefir granules, 5% sucrose); A1B3 (5% kefir granules, 10% sucrose); A2B1 (10% kefir granules, 0% sucrose; A2B2 (10% kefir granules, 5% sucrose) and A2B3 (10% kefir granules, 10% sucrose). The results of this study indicate that the treatment of kefir granules (5 and 10%) and sucrose (0.5, and 10%) have a significant effect on aroma, thickness, taste and overall acceptance, but not significantly different of color. The use of 5% kefir granule and sucrose 10 % levels (A1B3) is the preferred kefir. Keywords: Kefir granules, sucrose, sensory properties, suc
