Abstract

The purpose of this research was to know the effect of germination time of millet (Panicum milliaceum) on the characteristics of flakes and to know the right germination time of millet on the characteristics of flakes. The experimental design used was completely randomized design with the germination time of millet treatment, namely 24 hours (T1), 48 hours (T2), 72 hours (T3), 96 hours (T4), and 120 hours (T5). The treatment was repeated 3 repetitions then obtained 15 units of the experiment, the data obtained from the result were analyzed by variance and if the treatment had an effect on the variable then continued with Duncan test. The results showed that the germination of millet had significant effect to water content, ash content, protein content, fat content, crude fiber content, tannin content, taste level (hedonic test), and overall acceptance of flakes. 120 hours germination time of millet had the best characteristics with water content 1,36%, ash content 2,65%, protein content 9,93%, fat content 7,86%, carbohydrate content 78,20%, crude fiber content 5,93, tannin content 0,31%, color liked, flavor liked, texture crispy and liked, taste liked and overall acceptance liked.

Abstract

The purposes of this research were to know the effect of the using of  seaweed Eucheuma spinosum and the best concentration as a filler to the chemical, physical and sensory ice cream. The Randomized Block Design (RBD) were used to evaluate the research with five treatments of E. spinosum concentration such as: 0, 5, 10, 15 dan 20% and three replications to obtain 15 units experiment. The variables measured were fat, protein, ash, crude fiber content, melting resistance, aroma, texture, color, flavor and overall acceptance. The data were analyzed by SPSS 17th version and if there was impact on the treatments, it would be followed by Duncan Multiple Range Test (DMRT). The results showed that E. spinosum were significantly effect to the chemical, physical and sensory ice cream. It could be concluded that the best result was obtained by using 10% of E. spinosum with the characteristics of 12,39% fat, 2,42% protein, 0,59% ash, 18,34% crude fiber, melting resistance of 367 seconds or 6 minutes 12 seconds, colour 4,1 (yellowish white), texture 3,5 (soft), aroma 3,9 (typical little milk), taste 5,5 (like) and 5,6 overall acceptance (like).

Abstract

The purpose of this research was to know the viability of Lactobacillus plantarum FNCC-0027 in apple juice with different varieties. This research is an experimental research. Viability data of L.plantarum FNCC-0027 on apple juice of Manalagi variety, Anna, and Romebeauty was described. Data from the analysis before and after fermentation by L.plantarum FNCC-0027 on each apple juice tested using paired T Test at a = 5%. The total of LAB from the three apple varieties decreased from 105 CFU/ml to 104 CFU/ml with a decrease by 1 log CFU/ml. The addition of L.plantarum FNCC-0027 gave a significant effect in total of sugar, total of acidity, and pH of three apple varieties. Anna's apple juice has the lowest decrease of total LAB after 48 hours fermentation with the final result is 0,63 x 104 CFU/ml, total of sugar 0,95%, total of acidity 0,44%, and pH 3,55%. Keywords : Lactobacillus plantarum FNCC-0027, variety of apple juice, LAB viability

Abstract

The objective of this research was to observe the effect of grape skin waste on the characteristic of jelly drink and to determine the appropiate treatment that produces jelly drink with the best characteristics. Data was analyzed using completely randomized design (CRD) with five levels such as 100g of grape skin waste, 200g of grape skin waste, 300g of grape skin waste, 400g of grape skin waste, and 500g of grape skin waste. Data were analyzed with analysis of variance and continued with Duncan’s Multiple Range Test. The result showed that the effect of each treatment gave significant effect to total phenol, vitamin C, anthocyanin, antioxidant activity and gave significant effect to characteristic of color, aroma, taste, and overall acceptance. The best treatment to produce jelly drink was 500g of grape skin waste, that gave average value total phenol 83.64 mg GAE/100g, vitamin C 35.92 mg/100g, anthocyanin 3.90 mg/100g, IC50 3872.36 ppm, color dark purple, aroma very typical grape, and texture slightly chewy, taste and overall acceptance was liked.

This study aims to determine the effect of wheat flour ratio with corn sprouts flour on the characteristics of flakes produced and the exact composition of wheat flour with corn sprouts flour that is able to produce flakes with the best characteristics. The experimental design used was Completely Randomized Design with treatment factor that is the comparative treatment of flour with corn sprouts flour which consist of 5 levels: 50%:50%; 40%:60%; 30%:70%; 20%:80%; 10%:90%. The treatment was repeated 3 times to obtain 15 units of experiment. The data obtained were analyzed by variance and if the treatment had an effect on the observed variable then continued with Duncan test. The comparison of wheat flour with corn sprout flour significantly affected water content, ash content, fat content, protein content, carbohydrate content, coarse fiber content, tensile strength, color (hedonic test), aroma (hedonic test), texture (hedonic test and scoring ), taste (hedonic test) as well as overall acceptance (hedonic test) flakes.

Abstract

This research aims to identify the effect of adding purple sweet potato flour to the characteristics of health-promoting yogurt and to identify the right concentration of purple sweet potato flour to produce health-promoting yogurt with the best characteristics. This research used a Randomized Block Design (RBD) of the addition of purple sweet potato flour with the concentration of 0%, 2%, 4%, 6%, 8%. Each treatment was repeated 3 times, resulting in 15 experimental units. The data were then Analyzed of Variance (ANOVA) method and if the treatment had an effect on the variable, the Duncan Multiple Range Test (DMRT) were performed. The results showed purple sweet potato flour has significant effect to lactic acid total, pH, antioxidant activity, color, texture, and taste of health-promoting yogurt and did not significantly affect LAB total, hedonic taste, aroma, and overall acceptance. The addition of 8% purple sweet potato flour resulted in the best characteristic under the following criteria: 1.23% of lactic acid total, 3.73 of pH, 90.33% of antioxidant activity, 13.19 log CFU/ml of LAB total, pink color and indefferent color, thick texture rather like, sour taste rather like, flavor and overall acceptance rather like.
