Abstract

Tomato is one of the food commodities that have the potential to be developed as probiotic drinks. This research aims to identify the effect of skimmed milk concentration on the characteristics of fermented tomato juice and to identify the proper concentration of skimmed milk in producing fermented tomato juice with the best characteristics. Fermentation of tomato juice used Lactobacillus rhamnosus SKG34 as isolates. The research was designed using Completely Randomized Design (CRD) with concentration of skimmed milk as treatment (0%, 2%, 4%, 6%, 8%, 10%). The data were analyzed by ANOVA and if the treatment affected the variable, then proceed with the Duncan test. The results showed that skimmed milk concentration had a significant effect on total LAB, total acid, pH, hedonic of color and skoring test (color, sour taste and sweet taste). The concentration of 4% skimmed milk produceded the best characteristic of fermented tomato juice with total LAB 1.04 x 1012 CFU/ml, total sugar 6.02%, total acid 1.49%, pH 4.01, preferred orange color, preferred aroma, preferred sour and slightly sweet taste, and preferred overall acceptance.

Abstract

This study aims to determine the effect of yeast concentration on the characteristics of corn tempeh and to determine the concentration of yeast to produce corn tempeh with the best characteristics. This study used a completely randomized design (CRD) with yeast concentration treatment consisting of 5 levels: 0.2%, 0.4%, 0.6%, 0.8%, 1%. The treatment was repeated 3 times to obtain 15 units of experiment. The data obtained were analyzed by analysed by variance and if the treatment had an effect on the observed variables, it was continued with Duncan's Multiple Range Test (DMRT). The concentration of yeast in the making of corn tempeh has a very significant effect on water content, ash content, protein content, fat content, carbohydrate content, aroma, color, taste, texture, and overall acceptance. The yeast concentration of 0.8% produced corn tempeh with the best characteristics, namely: water content 65.6%, ash content 0.05%, fat content 6.91%, protein content 9.57%, carbohydrate content 17.9%, color , taste, aroma, texture, overall acceptance was very like, the color is white, the texture is compact and the aroma and taste are typical of tempeh.

Abstract

This research aims to identify the effect of fermentation time with Lactobacillus rhamnosus MY2 isolate on the characteristics of peanut milk and determine the right fermentation time to produce fermented peanut milk with the best characteristics. This research used a completely randomized design (CRD) with variations in fermentation time which consisted of 3, 6, 9, 12, and 15 hours. The treatment was repeated 3 times to produce 15 experimental units. The data obtained were analyzed using the analysis of variance (ANOVA) method and if the treatment had a significant effect (P<0.05) on the observed variables, then continued with Duncan New Multiple Range Test (DNMRT). The results showed that the treatment of fermentation time had a significant effect on the pH, total LAB, total acid, the value of preference for aroma and taste, the value of score for sour taste and viscosity, and overall acceptance but had no significant effect on protein content, fat content, the value of preference for color and texture of fermented peanut milk. The 6 hours fermentation time produce the best characteristics of fermented peanut milk with criteria pH 5.43, total LAB 8.52 Log CFU/ml, total acid 0.13%, protein content 3.27%, fat content 22.78%, the color, aroma, sour taste, texture, and overall acceptability was liked.

Abstract

The research was conducted with the aims to determine the effect of mold concentration with Rhizopus oligosporus DP02 Bali on the characteristic of pigeon peas tempeh and to determine the appropriate yeast concentration to produce tempeh with the best characteristic. The experimental design that used in this research was a completely randomized design with the treatment consisting of 5 levels of mold concentration, namely: 1%, 2%, 3%, 4%, and 5%. Each treatment was repeated 3 times to obtain 15 experimental units. The data were analyzed by analysis of variance and if there was a significant effect, the Duncan Multiple Range Test were perfomed. The results showed the yeast concentration had a significant effect on water content, ash content, protein content, fat content, carbohydrate content, crude fiber content, color (hedonic and scoring test), taste (hedonic test), texture (hedonic and scoring test), and overall acceptance (hedonic test) and had no effect on the aroma (hedonic test). The result show that the tempeh with a concentration of 5% yeast resulting the best tempeh characteristic with the criteria of 62.64% water content, 0.69% ash content, 9.66% protein content, 3.31% fat content, 23.70% carbohydrate content, 11.13% crude fiber content, color sensory test, aroma, taste, texture, overall acceptance are liked.

Abstract

The research was conducted with the aims to determine the effect of yeast concentration with Rhizopus oligosporus DP02 Bali on the characteristics of green bean tempeh and to determine the righ yeast concentration to produce green bean tempeh with the best characteristic. The research used completely randomized design with yeast concentration consisting of 5 different levels as the treatment, namely 1%, 1,5%, 2%, 2,5%, and 3%. Each levels was repeated 3 times to obtain 15 experimental units. The data were analyzed using ANOVA, and if there was a significant effect, the Duncan Multiple Range Test were perfomed. The results showed that the treatment had a significant effect on the green bean tempeh water content, ash content, protein content, fat content, carbohydrate content, curd fiber content, aroma, taste, texture, color, and overall acceptance. Yeast concentration of 3% produced the green bean tempeh with the best characteristics with water content of 54.17%, ash content of 0.60% , protein content of 8.22%, fat content of 2.53%, carbohydrate content of 33.79%, curd fiber content of 9.48%, and characteristics of color was liked, taste was liked, texture was liked, and overall acceptance was liked.
