Abstract

This study aims to determine the effect of skim additional on the characteristics and the amount of the right skim additional of cow milk dadih made in wuluh bamboo (Schizostachyum bluneiness) tubes. The completely randomized design with 5 levels of skim addition treatment were : 4%, 6%, 8%, 10% and 12%. The treatment was repeated 3 times for obtain 15 experimental units. The data were analyzed by variance, and the significant effect of the treatment was followed by Duncan. The additional of skim has effect to yield, water content, pH, total acid, total microbes, total lactic acid bacteria (LAB) and has effect to scoring test of aroma, taste and overall acceptance by hedonic test, but doesn’t significantly affect scoring test of color and texture. The addition of 10% skim produces the best characteritics with yield 65,31%, water content 63,72%, pH 5,50, total lactic acid 1,31%, total bacterial colony 4,38 x 109CFU/g, total lactic acid bacteria (LAB) 3,42 x 109 CFU/g, color cream, typical aroma of fermented milk, solid texture, sour taste and rather dislike on overall acceptance. Keywords : cow milk dadih, skim milk, wuluh bamboo.

Abstract

This study was aimed to determine the effect of wheat flour comparison with red bean sprout flour on the characteristics of pancakes and to determine the exact concentration of red bean sprout flour that was able to produce pancakes with the best characteristics. This study used a randomized block design with the ratio of flour and red bean sprouts (100%: 0%, 60%: 40%, 50%: 50%, 40%: 60%, 30%: 70%), repeated three times to obtain 15 units of experiment. The data obtained were then analyzed by variants and if there was any effect on the treatment, then continued with Duncan test. The variables observed were moisture content, ash content, protein content, fat content, carbohydrate levels, coarse fiber content, and sensory characteristics. The results showed that the addition of red bean sprout effected moisture content, ash content, protein content, fat content, carbohydrate content, crude fiber content, colour, aroma, taste, texture, and overall acceptance of pancake. The best characteristic of pancake substitution was 50% wheat flour and 50% red bean sprout flour that produced moisture content 36.14%, ash content 1.86%, fat content 24.15%, protein content 8.31%, carbohydrate content 29.53 %, crude fiber content 16.81%, light brown colour (liked), typical aroma of red beans (liked), soft texture (liked), flavour of red beans (liked), and overall acceptance (liked).

Abstract

Lactobacillus sp. F213 (LbF213) is a lactic acid bacteria (LAB) that has the potential as a probiotic because it can provide health effects for those who consume it, so it is necessary to make efforts to increase the application of LbF213 in the field of food processing. This study aims to determine the effect of sucrose concentration on the characteristics of fermented soursop juice with LbF213 isolates and get the right concentration of sucrose to produce fermented soursop juice with the best characteristics. The experimental design used was Randomized Block Design with sucrose treatment of 0%, 3%, 6%, 9%, and 12%. Each treatment was repeated 3 times to obtain 15 experimental units. LAB total was analyzed descriptively and the other variables were analyzed by ANOVA and if there was an influence between treatments continued with Duncan test. The results showed that sucrose treatment affected total sugar, taste (hedonic), sour taste and sweet taste (score), overall acceptance (hedonic). The 6% sucrose treatment produced the best fermented soursop juice with a total LAB 1,27 x 1010 cfu/ml, total sugar 12.91%, total acid 1.57%, pH 3.83, color and aroma rather liked, with a slight taste sour and rather sweet liked, and overall acceptance liked. Keywords: fruit juice, lactobacillus sp. F213, sucrose concentration.
