Abstract

Chemical, physical, and microbiological damage of fruits and vegetables can occur during the transportation process. The percentage of damage can reach 30-50% if the treatment during transportation is not carried out properly. The research objective was to determine the quality changes in tomatoes after transportation simulation based on the arrangement of the fruit in cardboard packaging. The treatment in this research is tomato arrangement patterns: the face centered cubic (FCC) arrangement, the traditional arrangement and the jumble (farmer) arrangement. The research begins with a transportation simulation using a vibrating table in a vertical direction, using a frequency range of 3.9 Hz and an amplitude of 5.2 cm. The simulation is carried out in 1 hour. After the simulation at the 1st hour, amount of mechanical damage (bruising) on ​​every package was carried out. The results showed that the pattern of arranging tomatoes in cardboard packaging that gave the least damage was the FCC arrangement pattern. The FCC pattern only causes shrinkage of 0.11% and the smallest amount of mechanical damage (bruising) is 0.64%.

Abstract

Fresh-cut rambutan products not only have to look fresh, but must have sensory properties (aroma, taste, texture, and visual appeal) similar to fresh products, they must also be safe, healthy and nutritious. So it is necessary to characterize the quality, especially vitamin C from fresh-cut rambutan products which are vacuum packed and stored at frozen temperatures. The purpose of this study was to determine the effect of frozen storage on changes in vitamin C in minimally processed rambutan. The material used in this study was fresh rambutan fruit, Si Kuning variety, obtained from rambutan collectors in Tengguli Village, Sajad District, Sambas Regency. The fruit used is fruit at the ripe stage. The level of vitamin C at the beginning of storage was 14.0772%. The observed peeled rambutan was stored at -15 oC for 20 days, vacuum packed and without vacuum. The results of testing for vitamin C levels were carried out on the 20th day of storage. The level of vitamin C of rambutan after 20 days of storage which was stored at -15 oC decreased drastically when compared to the vitamin C content on day 0. The percentage of loss of vitamin C reached 60% in vacuum packaged rambutan, and the proportion decreased by 70% in non-vacuum packed rambutan.

Abstract

The aim of this study was to obtain a combination of blanching temperature and time in making candied jackfruit. Randomized factorial was used as research design within two factors, namely blanching temperature (80oC, 85oC, and 90oC) and blanching time (2, 3, and 4 minutes). The quality test of candied dried jackfruit includes organoleptic test of the hedonic scale scoring method namely taste, color, aroma, and texture. Chemical tests include water content, sugar content, and yield. The best treatment is a combination of 90oC blanching temperature and 4 minutes blanching time, which produces a product with a water content of 40.91%, a sugar content of 73.72%, even for yield raised up to 35.51%. Taste, color, aroma, and texture parameters did not show any real effect. Based on the results of the business feasibility analysis, it is found that the processing of the candied jackfruit processing industry is feasible to be cultivated on a small industrial scale.

Abstract

Nata de coco is made from raw coconut water which is fermented using the Acetobacter xylinum bacteria. This product has the characteristics of a white color, a thickness of approximately 1-2 cm and a chewy texture like a gel. The largest content in nata de coco is fiber known as bacterial cellulose. In addition to requiring sugar as a carbon source, making nata de coco also requires a source of nitrogen to activate the extracellular enzymes of the Acetobacter xylinum bacteria in the manufacture of nata cellulose. Sources of nitogen used in the manufacture of nata de coco generally use inorganic nitrogen sources, which in their development have caused many pros and cons, especially with regard to food safety issues when this product is consumed as a beverage. This study aims to obtain the best alternative nitrogen source and concentration in making nata de coco. The experimental design used in this study was nested randomized design with 2 factors as the first factor, the type of nitrogen source, while the second factor was the concentration of the nitrogen source in the first factor. The types of nitrogen sources used as the first factor were tofu industrial wastewater, green bean sprouts and Azolla microphylla, while the second factor was the concentration of nitrogen sources consisting of 4 levels, namely 0.5%, 1%, 1.5% and 2%. The parameters observed in this study were thickness of nata de coco, weight of nata de coco, crude fiber of nata de coco, number of Acetobacter xylinum cells in the nata de coco layer. The results showed that organic nitrogen sources (tofu, sprouts and Azolla microphylla liquid waste can be an alternative substitute for inorganic nitrogen sources (urea, ZA and ammonium sulfate) which have been commonly used in making nata. The highest quality nata de coco is produced from the treatment of organic nitrogen sources. sprouts with a concentration of 1.5% with a thickness of 2.83 cm, a weight of 279.33 grams, a crude fiber content of 4.14% and the number of Acetobacter xylinum cells in the cellulose layer 0.4 x 107 cells / ml.
