Abstract

The aim of this research is to make a formula of RUTF using combination of green pea and peanut as the base ingridients. By using this combination, it is expected that this product will have precise energy and protein content with good taste for children. Randomized block design was used and sensoric properties were analysed to get best formulation in term of nutrition content and sensoric properties. The eksperiment, there were ratio of peanut and green pea in that 6 formulations are 80:20,70:30,60:40,40;60,30:70, and 20:80. Data from statistical analysis showed that there is no significant difference in nutrition content and sensoric properties between 6 formulations (p>0.05). Selection of best formulation among these 6 formulations was done using effectitivity method. Using that method, RUTF which contains green pea and peanut with 6:4 ratio is the best product.

Abstract

This study aims to determine the characteristics of waste cooking oil in Denpasar to be known the quality of waste cooking oil so that utilization is not for consumption again but processed into non-food products with the appropriate preliminary treatment. The population in this research is all waste cooking oil produced in Denpasar city. Determination of research sample was done by using purposive sampling method with some consideration such as (1)Choice of hotel and restaurant with average occupancy above 70%/year, (2) Street food vendors and street snack vendors with daily proccess using 10 L cooking oil a day. So that obtained 21 samples of waste cooking oil from the three sources of sampling. The observed variables are water content, peroxide number and free fatty acid. The results showed that waste cooking oil which has the highest water content from the street food vendor amount 0,40%, while the lowest from hotel/restaurant amount 0,09%. The highest peroxide rate were obtained on street snack vendors amount 13,27 MeqO2/1000 while the lowest were hotel/restaurant amount 12,76 MeqO2/1000. The highest free fatty acids were obtained by street food vendor amount 0,35%, while the lowest from hotel/restaurant amount 0,19%.

Abstract

To reduce dependence on wheat flour were utilizing Indonesia local products. Taro tuber as a potential source of dietary fiber but protein quality is low. An alternative to improve protein quality is by the addition of tempeh flour. Flakes from taro flour and tempeh flour is expected to be an alternative food to ensure adequate intake of dietary fiber and protein. To analyze the effect of taro flour and tempeh flour addition on water content and organoleptic quality of flakes.The study of flakes using Complete Random Design, with two factor and each treatment combination was repeated 3 times. They were wheat flour:taro flour:tempeh flour (20%:65%:15%); (20%:50%:30%) and (20%:35%:45%). Statistical analyzed of water content used Anova One Ways and organoleptic test used Friedman test. Flakes with 20% wheat flour, 65% taro flour, and 15% tempeh flour have a lowest water content 4,2%, but was still bellow standart specified by SNI and had a significant effect (0,00 < ? 0,01) on water content. Taro and tempeh flour on flakes had significant effect on aroma (0,038 < ? 0,05), taste (0,00 < ? 0,05), and, texture (0,00 < ? 0,05) but had no effect on colour (0,07 < ? 0,05). Colour, aroma, taste and texture of flakes the most preferred on 20% wheat flour, 65% taro flour, and 15% tempeh flour. Best proportion of the organoleptic quality that is in the proportion of 20% wheat flour, taro flour 65% and 15% tempeh flour. It is advisable to pay attention to the proportion of the addition of taro flour and soybean flour in order to get the moisture content and good organoleptic quality.

Abstract

Limited functional characteristic of taro starch cause limited application on food product. It is a reason for physical modification of starch with autoclaving-cooling method intended to improve physical, chemical and functional characteristics of taro starch to broaden its usage on food industry and to increase its added value as functional food. In this research, taro starch modification was done with autoclaving-cooling method through modification cycles consisting of without cycle, one cycle, and two cycles. The results indicated that the best treatment is two-cycle autoclaving-cooling modification with swelling power of 8.28 g/g, solubility of 3.77%, amylose of 29.96%, resistant starch of 4.38% and no viscosity peak, but increase in viscosity continuously occur during heating till cooling of 3133.33 cp.

Abstract

Liquid pulp by-product of fermentation of cocoa beans can be processed into cocoa vinegar. Cocoa vinegar as a new food product needs to be determined its shelf life. The objectives of this study were: (1) to know the stability of cacao vinegar distillate products during storage, and (2) to determine the shelf life of cocoa vinegar distillate using Accelerated Shelf-Life Testing (ASLT) method based on Arrhenius approach for determination of expired period of product. In this study, the storage of cocoa vinegar distillate for 10 weeks at three different temperatures, namely: 28oC, 40oC, and 50oC, and each experiment was done twice repeated. Weekly observations were done on the characteristic parameter of cocoa vinegar distillate. The results obtained show that: (1) during storage there is a decrease in acetic acid concentration, but an increase in pH, TSS and clarity value (OD600) of cocoa vinegar distillate; (2) the determination of shelf life is based on pH characteristics with equation of Ln k = -2217.2 (1/T) + 5.1875, which shelf life at temperatures: 10oC, 20oC, 28oC, 40oC, and 50oC respectively: 35.28 weeks (8.23 months), 27.01 weeks (6.30 months), 22.09 weeks (5.15 months), 16.65 weeks (3.89 months), and 13.37 weeks (3.12 months). The data of shelf life may be used to specify the expiration period, which must be included in the packaging label.

Abstract

Decaffeination is a process for reduction of caffeine content in coffee beans. This study is aimed to find out the effects of papaya’s sap (Carica papaya L.) addition on the caffeine content of robusta coffee and to know the concentration of papaya’s sap addition that could produce decaffeinated coffee according to the requirements. This study used a Completely Randomized Design (CRD), with five levels of papaya’s sap concentration namely 0%, 1.5%, 3%, 4.5%, and 6%, and 3 repetitions, so that obtained 15 experimental units. The results of the study showed that the use of papaya’s sap affected caffeine content of robusta coffee. Addition of 6% papaya’s sap produced decaffeinated coffee according to the requirements, with the caffeine content of 0.24%, moisture content of 11.34%, ash content of 0.07%, and protein content of 9.72%.

Abstract

Edible films is a thin layer packaged which produced from biopolymers and food-grade additives which is biodegradable in consumtion and environment. Sweet potato starch is one of many hydrocolloid which can be made as the material of edible film. Glycerol added in the formulation of edible film as a plasticizer to increase the characteristic of edible film. The purpose of this research is to determine glycerol concentration which it had best physic and chemist characteristics of edible film. The method of this research was completely randomized design with four grade of glycerol concentration there are 10%, 15%, 20% and 25% (v/b starch) which repeated four times. There are many parameters which analyzed in this research there are moisture content, thickness, water vapor transmission rate (WVTR), elongation and tensile strength. Data was analyzed with ANOVA and continued with Duncan’s (?=5%). The result of the research are increasing the glycerol concentration were influence amount of water moisture, thickness, elongation and tensile strength, but it is not influence the amount of water vapour transmission rate edible film. Best characteristic of edible film shown in formulation 10% (v/b starch) glycerol with amount of water moisture 12,50%, thickness 0,06 mm, WVTR 1,79 g/m2, elongation 8,75% and tensile strength 0,75 MPa.
