Abstract

This research was conducted in order to determine observe and obtain the type of this solvent and extraction time to produce oil avocado seed with the highest antioxidant activity. The experimental design used in research was a factorial completely randomized design which consisted of two factors. The first factor was the type of solvent consisting of n-hexan, isopropyl alcohol, and petroleum ether. The second factor was the extraction time consisting of 1, 2, and 3 hours. The treatment was repeated twice to obtain 18 units of the experiment. Data were analyzed with analysis of variance, followed by Duncan test. The results show that the solvent of isopropyl alcohol and extraction time 2 hours resulted highest antioxidant activity with total carotenoids 140.27 ppm, total tocopherol 218.75 ppm, the antioxidant activity (carotene bleaching) 83.33%, the antioxidant activity (DPPH) 54.52% and yield 16.39%.

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

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

The aim of this research was to determine the potential of Lactobacillus rhamnosus A6 isolated from breast milk as a starter in the manufacture of yoghurt. The random design uses for the research with one factor treatment using different types of starter such as L. rhamnosus A6 as single starter, Streptococcus thermophilus and L. bulgaricus, L. rhamnosus A6 and L. bulgaricus, L. rhamnosus A6 and S. thermophilus, and L. rhamnosus A6 with S. thermophilus and L. bulgaricus. Milk was pasteurized at 80°C for 15 minutes and then added 6% starter culture according to the treatment. Each treatment was repeated 3 times to obtain 15 experimental units. The data obtained were analyzed by ANOVA and if there was any difference followed by Duncan test (DMRT). The best treatment was L. rhamnosus A6 with S. thermophilus and L. bulgaricus with good characteristic which content 3,16% protein; 3,74 x 106 CFU/ml total LAB; pH of 4,64; 0,53% total lactic acid; 408,3 mPas viscosity; color (white and like), aroma (acid and like), flavor (acid and like), texture (thick and like), and overall acceptance (like).

Abstract

Potentials of tabah bamboo shoots flour as source of prebiotics need to be explore by extracting and identifying its oligosaccharide contents, will provide complete information about bamboo tabah flour potentials. In processing tabah bamboo shoots obtained every 1000 grams of tabah bamboo shoots will be obtained ± 250 grams tabah bamboo shoots (edible part) dan will produce ± 10.08 grams of tabah bamboo shoot flour. Tabah bamboo shoots flour rendemen was ± 0.97%The extraction with 70% ethanol solvent has the highest yield (2.62%), followed by distilled water (1.28%), and ethyl acetate (0.92%).Observations made on the color and yield showed a difference, whereas the consistency of the extract did not difference.Extraction was conducted using 70% ethanol solvent, (polar), ethyl acetate (semi-polar), and distilled water. Qualitatively phytochemical analysis was conducted. The isolation of oligosaccharide was conducted using column chromatography, Thin Layer Chromatography (TLC) and High Performance Liquid Chromatography (HPLC). The phytochemical analysis of tabah bamboo shoots flour in 70% ethanol discovers that it contains steroid, tannin, and saponin, which are antibacterial compounds. The purification of the extract of tabah bamboo shoots flour yields two main oligosaccharide components: glucose, sucrose and raffinose.

Abstract

The objectives of this study were to determine the effect of germination time on protein digestibility, antioxidant activity and functional characteristics of kidney bean (Phaseolus vulgaris L.) sprouts flour and characteristic of kidney bean sprout biscuits. This study used Completely Randomized Design with three replications. This research was conducted with three stages were: a) Making kidney beans sprouts with germination time were 0, 24, 36, 48 and 60 hours. b). Making kidney bean sprouts flour and analysed of protein digestibility by in vitro analysis, antioxidant activity and functional properties of kidney bean sprouts flour. c). Making biscuit from kidney bean sprouts flour and analysed the characteristic of biscuit. The results showed that germination process increased protein digestibility, decreased IC 50% value, increased fat absorption capacity and water but decreased swelling volume and solubility. Protein digestibility ranges from 52.73% to 54.29%, antioxidant activity ranges from 26.33 to 24.77 (IC 50%). Oil absorption capacity ranges from 81.30 to 90.26%, water absorption capacity of flour ranges from 119.56 to 128.03%, swelling power ranges from 3.58 to 3.33 (g/g) and the solubility ranges from 25,86 to 30.11 (%). Based on statistical analysis, the best treatment was kidney bean sprouts with 48 hours of germination. This flour was selected for making biscuits. The best biscuits were obtained from the treatment of 40% wheat and 60% kidney bean sprouts flour with criteria were 2.86% of moisture content, 2.61% of ash content, 19.79% of fat, 8.03% of protein and 66.71% of carbohydrate.
