Abstract

The aim of this research was to determine the effect of etanol vapor on the quality and the shelf life of Barangan Banana. Three different volumes of ethanol, namely 0 ml, 3 ml and 6 ml, were trapped in the 5 gram carrageenan placed in the tea sachets. The sachet was then put on the basal of styrofoam tray on which 3 fruits were placed and then wraped by streching film LDPE. Control fruits or un-treated fruits were also provided as comparison. The result showed that the ethanol vapor treatments significantly reduced the intensity of spoilage, the change color of fruit surface, vitamin C and total acidity compared to the control fruits. The ethanol vapor was also able to give better preferences of panelists on the color and flavor of the aril, as well as the overall performances of the fruits compared to the controls. Of the various ethanoltreatments, the shelf life of the 15th day with 6 ml of ethanol per package creates the best vapor to inhibit the rate of damage, change quality, and increase liking for panelists.

Abstract

This study aimd to determine the effect of temperature and drying time on the chemical and sensory characteristics of Tabah bamboo leaf tea. This study was designed using a Completely Randomized Design (CRD) with two factors, namely the drying temperature factor (50oC and60oC) and the drying time factor (1 hour, 2 hours, and 3 hours). The treatment was repeated three times to obtain 18 experimental units. The parameters observed were water content, pH, totalacid, total phenol, color, aroma, taste, and overall acceptance tested organoleptically. The results showed that the interaction of temperature and duration of drying of Tabah bamboo tea leaves had a significantly different effect on water content, pH, total acid, total phenol, color, overall reception, but did not have a significantly different effect on aroma and taste. The best treatment was water content 6.881%, pH 6.6, total acid 0.73%, total phenol 84.01 mg/100g, color 4.33, aroma 4.47, taste 4.27 and overall acceptance 4.47.

Abstract

Bamboo “Tabah” is one of the bamboo variety of which finds only in Bali island. "Tabah" bamboo leaves have the potential to be developed as raw materials for making tea that can produce drinks with various benefits. If utilized optimally, "Tabah" bamboo leaves can be processed as a product that will provide an advantage. This study aims to determine the effect of steam blanching and drying process on the activity ofwater content, pH, total acid, total phenol, and organoleptic " Tabah" bamboo leaf tea. "Tabah" bamboo leaves are treated with steam blanching time with a variation of time, namely for 10 minutes, 15 minutes and 20 minutes. After steam blanching, the "Tabah" bamboo leaves are dried using an oven with variations in the drying temperature of 50°C, 60°C and 70°C. The research method used was an experimental method with a completely randomized design (CRD) factorial pattern consisting of two factors and repeated three times. The first factor is the steam blanching time and the second factor is the drying temperature. The results showed that the best combination of treatments based on the overall acceptance of hedonic tests produced on “Tabah” bamboo leaf tea is the treatment of 15 minutes steam blanching time with a drying temperature of 60°C (W2S2) which produces 7.03% water content for SNI water content 8%, pH value 6.40, total acid value 0.94%, total phenol content 54.95mg/100g , color scoring test 4.47, aroma scoring test 4.87, taste scoring test 4.60 and overall acceptance hedonic test 4,67.

Abstract

Mangosteen is one of the horticultural products that easily damages and has a relatively short shelf-life. The abilities of the mixed of APSA 80 and sesame (Sesamun indicum L.) with different concentrations as coting materials to maintain the quality and extend the self-life of mangosteen fruits were tested during storage. The main objective was to find the best mixed showed that the mixed concentrations of 0.06% APSA 80 and 0.5 % sesame oil, as well as the mixed concentrations of 0.06% APSA 80 and 1.0 % sesame oil were the best coating materials to maintain quality concentrations of the APSA 80 and Sesame oil as coating material for mangosteen fruits. Sesame oil is known to be the most resistant to rancidity because it contains natural antioxidants and high oleic acid. APSA 80 is as a spreader and gluing the mixed material and as an emulsifier. The experimental design used in this study was a Completely Randomized Design with three factors, namely the concentration of APSA 80 (0%, 0.03%, and 0.06%), the concentration of sesame oil (0%, 0.5%, 1%) and storage temperatures (28 ± 2oC and 10 ± 1oC). The result and extend the self-life ofmangosteen fruits. The both formulations of the coatings maintain the self life for 25 days at where the colorsof the arils were snowy white, the color of skin surfaces were redish purple, and the pericarps were not yet hardenings.

Abstract

The purpose of this study was to determine the effect of ethanol vapor treatment on the quality and shelf life of Siamese citrus fruits at room temperature. This study used a Completely Randomized Design (CRD) with 3 different volumes of ethanol; 0 ml, 3ml, and 6 each were trapped in 5 grams of carrageenan which had been 10 ml of distilled water and put into a tea sachet. Sachets are then placed on styrofoam bases where there are 5 Siamese oranges, then covered with LDPE stretch film plastic. Siamese citrus fruit without treatment or control is provided as a comparison. The fruit is then stored at room temperature (28 ± 20). Weight loss, damage intensity, vitamin C, total acid, total dissolved solids, color, hardness, and organoleptic tests were observed during storage. The results showed that the general ethanol steam treatment had a significant effect in reducing the level of damage, weight loss slowed the rate of change in hardness, skincolor, total dissolved solids and vitamin C compared to controls. Similarly ethanol vapor is able to provide a higher panelist preference for color, taste, aroma and overall appearance compared to controls. From the various treatment volumes of ethanol 6 ml ethanol packaging creates the best vapor to slow down the rate of damage, change the quality, reduce shrinkage and increase the preference of panelists.
