Abstract

This study aims to determine the level of concentration of calcium chloride and vacuum air on the quality of tomatoes. Post-harvest handling of tomatoes was done by giving treatment concentration of calcium chloride solution different (0, 6, 9, 12%) and determined the best treatment then treated with vacuum air (430, 540, 650, and 760 mm Hg). Observations were made of the color, hardness and weight loss. The results showed that the use of calcium chloride with vacuum air significant effect on the value of color, hardness and changes in fruit weight. The use of calcium chloride with a concentration of 12% is the best, because it can maintain the color values of 6.02%, 7.76% hardness, and can press the fruit weight loss of 1.04%. The level of vacuum air 430 mm Hg can maintain the color values of 6.79 and can reduce fruit weight loss of 2.95%.

Abstract

Manggo (Mangifera indica) seed is one of the high yield carbohydrate source and can be functioned both as food and as an alternative food source. Processing of mango seed into flour can not only improve food diversification but also can made it to be classified as high valued commodities. In addition flour made from mango seed are meant to reduce the number of spoiled seed as well as discarded seed, and it can also be used as basic ingreditent for various processed product. This research was aimed both to study and to know the nutritional content two types of mango seed flours. A Completely Randomized Experimental Design (CRD) with types of mango seed as treatment was applied. The levels of the treatment including “Madu” mango seed flour and “Arummanis” mango seed flour. Observed variables were moisture, ash, carbohydrate, protein, colour and aroma. Result showed that flour made from different type of mango seed had difference multitional content. Flour from “Madu” mango seed had the moisture, ash, carbohydrate, and protein content of 15.00, 1.06, 48.11, and 3.48%, respectively. Whereas flour from “Arummanis” seed had the respected values of 12.34, 0.97, 52.74, and 3.40%, consectively. The colour of the flour was found to be white (2.75) and it had the aroma of mango imparted (2.71).

Abstract

Snake fruit (Salaca edulis Reinw) has a taste of sweet and sour, with a strong astringent edge. Snake fruit can be processed into chips in order to prolong its shelf life. Fruit chips processed with vacuum frying technology does not compromise the form, taste, colour, and aroma of the native fruits. However, in an effort to obtain crisp and tasteful snake fruit chips, the temperature of the vacuum frying process should be adjusted accordingly. Results showed the frying temperature of 70°C resulted in the chips which had Vitamin C, total acidity, and moisture contents of 0.11 mg, 16.05%, and 12.74%, respectively. When chips were fried with 80°C, the resulting product had a Vitamin C of 0.12 mg, total acidity of 16.14%, and moisture of 14.02%. Whereas chips with lower Vitamin C, total acidity, and moisture contents of 0.09 mg, 8,54%, and 6.01%, subsequently resulted from frying with 90°C. Keywords: chips, snake fruits, vacuum frying
