Abstract

South Kalimantan's pre-eminent cowpea, namely Nagara beans, needs to be improved, one of them being sprout flour. The purpose of this study was to (1) analyze the chemical and physicochemical properties of Nagara bean sprout flour on a small scale; (2) determining the best soaking and germination time on a small scale; and (3) comparing the chemical properties of Nagara bean sprout flour between small scale and scale up. The method used is making Nagara bean sprout on a small scale with an amount of 500 g, while on a scale up making sprout with an amount of 3000 g. Making sprouts on a small scale soaking for 12, 18, and 24 hours and germination for 24, 36, 42 and 48 hours. The germination for scale up is done with the best soaking and germination time of small-scale results, namely soaking for 12 hours and germination for 48 hours. The result is that soaking time only affects protein and carbohydrate content, whereas the interaction between soaking and germination time only affects the protein content of Nagara bean sprout flour. The best Nagara bean sprout flour is produced with a 12 hours soaking time and 48 hours germination time. Changes in the scale of the process of germination of Nagara bean sprout flour from small scale to scale up caused a decrease in levels of ash, protein and vitamin C content and an increase in levels of fat, carbohydrates, Fe, Ca, and vitamin E content.

Abstract

Kepok bananas are a fruit with a very fast ripening process when stored at room temperature.In this study, kepok bananas were packed with active packaging made from palm kernel shell activated charcoal, which was activated by 20% phosphoric acid in sachets to slow down the ripening process. This study was aimed to analyse the tendency of changes in the physical and chemical properties of kepok banana with active packaging made from palm kernel shell activated charcoal stored at room temperature and to determine the best active packaging that can extend the shelf life of kepok bananas. The old and ready-to-harvest kepok bananas were weighed as much as 350 g and packed with LDPE in the middle as primary packaging and foam net as secondary packaging. The kepok bananas packaging was added with 5 or 10 g of activated charcoal in the sachets packed with LDPE or tea bags. Kepok bananas with active packages were stored at 28 ± 2oC for 16 days and observed every two days in the form of weight loss, edible parts, moisture content, total dissolved solids, reducing sugar content, and total dissolved acid. The data were analyzed by regression order 2, order 3 or order 4 adjusted to the R2 value close to 1. The results showed that during storage the weight loss of kepok banana increased quadratically. The edible part changes followed the order 4 pattern, while the moisture content, total dissolved solids, reducing sugar content, and total dissolved acid followed the order 3 pattern. The best active packaging to extend the shelf life of kepok bananas was kepok bananas with 10 g of active charcoal in LDPE packaging.
