Abstract

Penelitian ini bertujuan untuk mengembangkan produk ganula ubi kayu dengan suplementasi tepung kecambah kedelai. Dari analisis ragam didapatkan hasil bahwa granula ubi kayu yang disuplementasi dengan tepung kecambah kedelai 10 persen, 15 persen, dan 20 persen memiliki nilai kesukaan yang tidak berbeda nyata dalam hal rasa, warna, aroma dan tekstur. Granula ubi kayu yang diberi perlakuan penambahan Na2S20s 0,0 persen dan lama sangrai 20 menit serta penambahan Na2S205 0,1 persen dan lamasangrai30 menit memiliki nilai kesukaantertinggi dibandingkan perlakuan yang lain untuk atribut rasa. Dalam hal atribut tekstur, nasi ubi kayu dengan penambahan Na2S20s 0,0 persen dan variasi lama sangrai 30 menit memiliki nilai kesukaan terbaik dibandingkan dengan perlakuan yang lain. Berdasarkan hasil uji pembobotan, produk terbaik adalah granula ubi kayu yang diberi perlakuan suplementasi tepung kecambah kedelai 20 persen tanpa penambahan Na2S20s dan lama sangrai 20 menit. Produk granula ubi kayu terbaik memiliki densitas kambasebesar 0,62 g/ml, kadarair5,95persen, kadarprotein 11,31 persen, kadar lemak 0,87 persen, kadarabu 3,04persen,kadar karbohidrat 78,83 persen, kadar pati 45,21 persen, kadarserat 2,50 persen, daya rehidrasi 3,76g air/g, dan kadar HCN 12,30 ppm.The objective of this research is to develop a cassava granule product supplemented with soy sprout flour. Byusing the analysis of variance, itis found that the supplementation of soy sprout flour at the rate of 10percent, 15percent and20 percent do notcause anydifferences in terms of color, texture, aroma, and taste ofthe products. Cassava granules bleached bythe addition of0.0percent of Na2S20s and roasted for 20 minutes, and the addition of 0.1 percent of Na2S20s and roasted for 30 minutes have the highest score of taste among the other products. For the texture attribute, cassava granules treated bythe addition of 0.0 percent of Na2S205 and roasted for 30 minutes have the highest score.Based on the weighted method, it is found that the bestproduct is produced bythe supplementation of 20percent ofsoy sprout flour, without the addition ofNa2S20d and roasting for 20 minutes. The product had the following characteristics: bulk density of0.62 g/ml, and the contents ofmoisture, protein,fat, ash, carbohydrate, starch, and fiber are 5.95, 11.31, 0.87, 3.04, 78.83, 45.21, and 2.50 percent respectively. The rehydration rate is 3.76 g water/g, with the content of 12.30 ppm of HCN.

Abstract

Penelitian ini bertujuan untuk menentukan umur simpan produk granula ubi kayu dengan menggunakan model isoterm sorpsi air dan pendekatan kadar air kritis. Kurva isoterm sorpsi produk granula ubi kayu berbentuk sigmoid. Uji ketepatan model persamaan kurva isoterm sorpsi menunjukkan bahwa model Henderson paling tepat menggambarkan kurva isoterm sorpsi granula ubi kayu. Granula ubi kayu memiliki kadar air awal 4,92 persen (bk) dan kadar air kritis 15,24 persen (bk). Hasil perhitungan menunjukkan bahwa granula ubi kayu yang dikemas dalam LDPE, MDPE dan PP pada RH 95 persen mempunyai umur simpan masing-masing 256 hari (8.5 bulan), 427 hari (14 bulan), dan 693 hari (23 bulan).The objective of this research was to predict the shelf life of cassava granule using moisturesorption isotherm model based on critical moisture approach. The sorption isotherm curve of the product showed to be sigmoidal. The Herderson model was found to be the best-fit for the product The product had an initial moisture content of 4.92 percents (db) dan a critical moisture content of 15.2 4percents (db). Based on calculations, the shelf life of cassava granules packaged in LDPE, MDPE, PP and stored at relative humidity of 95 percents, had shelf lives of 256 days (8.5 months), 427 days (14 months), and 693 days (23 months) respectively
