Abstract

The by-product of fermented cocoa seeds could be fermented into cocoa vinegar. However, the product requires to be distilled to be purified. In this study, an experiment was conducted to determine the percentage in taking the best distillate to produce the best characteristics of cacao vinegar. The percentage was started from 30, 50, 70, and 90% (v/v). The best treatment was determined according to the total acids, acetic acid, total sugars, total soluble solids and pH and distillation time. The result showed that taking distillate volume affected the total acid, acetic acid, and distillation time, and did not affect the total soluble solids, total sugar and pH value. The best distillate preparation of distillate process of cacao vinegar was volume 90% (v/v) with total acid of 0,25 meq NaOH/g, 1,51% acetic acid, pH 2,96, total sugar 0,079%, total soluble solids 1,13oBrix, with a distillation time of 120,25 minutes.Keywords: cocoa, distillation, volume percentage, fermented vinegar

Abstract

The atms of this study were (1) to knowing the change of quality characteristics from destilated fermentation vinegar from pulp liquid waste of cocoa beans during storage dan (2) to determine shelf life of destilated fermentation vinegar from pulp liquid waste of cocoa beans using Accelerated shelf-life testing (ASLT) method with Arrhenius approach. The observed Parameters is temperature. The temperature is 30 °C , 40 °C and 50 °C. The Observed variable is acetic acid content, pH, total dissolved solids and absorbance. The result showed that acetic acid content had the greatest decrease in 50 °C temperature. This shows that acetic acid content are inversely proportional to temperature rise. While the content of pH, total dissolved solids and turbidity experienced the greatest increase in 50 °C temperature. This shows that pH, total dissolved solids and turbidity are proportional to the temperature rise. The results of the calculation showed that at a temperature of 20 °C, 30 °C, 40 °C and 50 °C has a shelf life of 226 days, 167 days, 126 days, 96 days andn 75 days.

Abstract

Cocoa bean husk is a waste of cocoa processing that is large enough and has not been used optimally. Cocoa bean husk can be used as a natural antioxidant by extracting the polyphenol compounds. This research aim to find out the effect of temperature and maceration time on the of cocoa bean husk extracts as a source of antioxidants and to determine the best temperature and time of maceration to produce cocoa bean husk extract as a source of antioxidants. This experiment used a factorial randomized block design with two factors. The first factor was maceration temperature consisting of 30±2?C, 40±2?C, dan 50±2?C. The second factor was maceration time consisting of 24, 36 and 48 hours. The data was analysed by analysis of variant and continued with the Tukey test. The results showed that maceration temperature had a very significant effect, while maceration time had a significant effect on yield, total phenolic, and antioxidant capacity. whereas the interaction between treatments had no significant effect on yield, total phenolic, and antioxidant capacity. The best treatment to produce cocoa bean husk extract as a source of antioxidants is to use a maceration temperature of 50±2?C and a maceration time of 48 hours with a yield characteristic of 2,77 percent, a total phenolic value of 72,35 mg GAE / g, and a capacity antioxidants amounting to 17,45 mg GAEAC / g, Keywords : cocoa bean husk, extraction, polyphenol, antioxidant.

Abstract

Cocoa vinegar is a fermented vinegar produced from a product of cocoa bean fermentation. The aims of this study were to determine quality change of cocoa vinegar during retention and determine its self-life by using Accelerated Shelf-Life Testing (ASLT) method by Arrhenius Equation Approach. This research was conducted by using one factor, and it was storage temperature treatment that consisting of 3 levels, 30, 40 and 50?C. Retention and observation start from 0 week until 16 weeks, with parameters that observe were acetic acid, pH, total suspended solid and turbidity. Cocoa vinegar has decreased quality during storage, at 30?C, 40?C and 50?C. During storage of the three temperatures, the temperature of 50?C suffered the most rapid deterioration with the characteristic of decreasing the acetic acid content by more than 50%, and the increase of pH, total suspended solid and turbidity on the 63rd day. Shelf life of cocoa vinegar by using the characteristic of acetic acid with linear regression equation y = -4624.x + 10.30 with R² = 0.999.at storage from temperature 10, 20, 30, 40, and 50?C respectively were 431 days (14.3 months). 246 days (8.20 months). 146 days (4.86 months). 89 days (2.96 months).and 56 days (1.86 months).

Abstract

Body scrub cream is a semi-solid dosage form containing one or more dissolved or dispersed medicinal ingredients in suitable base ingredients and serves to smooth the body's skin and remove damaged skin cells with the help of scrub material. Oyong fiber (Luffa acutangula) is used as a scrubber material that is natural, biodegradable and inexpensive. The aim of this study to know the effect of the addition of oyong fiber powder and stirring time to the characteristics of body scrub cream and to determine the percentage of the addition of oyong fiber powder and length of stirring to produce the best body scrub cream. This research uses factorial randomized block design with two factors. The first factor is the percentage of the addition of the Oyong fiber powder consisting of 3 levels namely 5, 7, 9 and 11% and the second factor is the stirring time consisting of 10, 15, and 20 minutes. Data were analyzed by analysis of variance and continued by Tukey's test. The results of the study showed that the addition loofah (Luffa acutangula) fiber powder addition and the stirring time very affected the pH, viscosity, spreadability power, adhesion power and overall acceptance of the body scrub cream. The interaction between the addition loofah (Luffa acutangula) fiber powder addition and the stirring time very affected the viscosity and the spreadability power. Addition of 9% of loofah (Luffa acutangula) fiber powder and 20 minutes of the stirring time was the best treatment for body scrub cream with characteristics as follows: pH 4.60, viscosity 37600 cp, homogeny, spreadability power 4.6 cm, adhesion power 9.88 seconds, separation ratio=1 and overall acceptance 5,90 (rather like to like).

Gracilaria sp. is one type of red algae containing phycoerytrin pigment. Phycoerytrin pigment can be used as a natural dye to replace synthesis dyes. Phycoerytrin is widely used as a natural dye for foods and cosmetics. The purpose of this research was 1) to determine the effect of variations pH buffer solution on the characteristics of red algae extract (Gracilaria sp.), 2) to determine the best pH buffer solution used to produce red algae extract (Gracilaria sp.). This study used a factorial Randomized Block Design with group variation of pH buffer. The treatment of materials with solvent variation of pH buffer consist of 8 level, namely: 3, 4, 5, 6, 7, 8, 9 and 10. Each treatment are grouped into two time-based implementation. The results showed that each treatment of pH buffer variation significantly affected the yield, the degree of phycoerytrin pigment, brightness (L *), redness (a *) and yellowish (b *). Buffer pH 7 produced the best extracts in red algae (Gracilaria sp.) with a yield of 0.6030%, pigment production 0.933 mg/g, brightness value 18.650 L *, redness value 24.470 a * and yellowish value 10.135 b *.

Abstract

Brem waste has sugar content of 12% and its starch content is 10.8%. Components contained in the brem waste are expected to be able to be used to produce Ca-citrate The purpose of this research was to find out the media’s initial pH effect and fermentation time on Ca-citrate production from brem waste by using Aspergillus niger ATCC 16404. The research was an experimental research using the randomized block design with the factorial experimentpattern that consists of two factors. The first factor was the media’s initial pH (3, 4, 5, and 6), and the second factor was the fermentation time (3, 5, and 7 days). The result showed that theinitial pH of medium fermentation affected the medium pH after fermentation and production of Ca-citrate, but it didn’t influence the total soluble solid of medium fermentation.Fermentation time influenced Ca-citrate production, final pH, and total soluble solid of fermentation medium. The fermentation with media’s initial pH of 5 and the fermentation for5 days was the best combination treatments to produce Ca-citrate which the production levelwas 5,35 ± 0,06 g/L.
