Pengaruh Lama Perendaman Biji Nangka Dalam Natrium Metabisulfit Dan Cara Pengeringan Terhadap Kualitas Tepung Biji Nangka

Jackfruit seeds are the source of carbohydrate, protein and energy. Jackfruit seeds have pouch of high carbohydrate, so they have potential in making flour. This research has goal to know the influence of long submerging jackfruit seeds in natrium metabisulfit and the way in drying to the quality of jackfruit seeds flour. This research uses completing disordered plan, factorial pattern contains of 2 factors. The first is the long submerging jackfruit seeds in natrium metabisulfit 600 ppm (N) these are 3 hours (N1), 4 hours (N2), and 5 hours (N3). The second is the way in drying (P) which is use 70°C during 2,5 hours (P1) and sun rayduring 3-5 days (P2). The parameter used is the degree of carbohydrate and the quality of flour which are including the texture, the color, the aroma, and the capacity of receiving. The result of this research shows that the long factor in drying in natrium metabisulfit has influence on the degree of carbohydrate and not influence on the quality of flour which are including the texture, the color, the aroma, and the capacity of receiving. The way in drying has influence in the degree of carbohydrate, the color, the capacity of receiving and not influence in the texture and the aroma. The highest degree of carbohydrate can be found in long treating of drying jackfruit seeds in natrium metabisulfit during 3 hours with the oven 70°C in drying during 2,5 hours (N1P1)

Aktivitas Antioksidan dan Kualitas Organoleptik Kopi Bubuk Non Kafein dari Biji Pepaya dan Buah Nangka dengan Lama Penyangraian yang Berbeda

Generally coffee drink is a beverage produced from the processing of coffee beans. It’s containing high caffeine that if consumed in excessive amounts will adversely affect the health, because it have been decaffeination technology to reduce levels of caffeine in the coffee. But the technology was considered too expensive. The coffee drinks are made from papaya seeds combined with jackfruit be an alternative to decaffeinated coffee. This study aims to determine the organoleptic qualities (color, texture, flavour, taste) and antioxidant activity of coffee powder from a combination of papaya seed and jackfruit with different long roasting. This research method using a completely randomized design (CRD) with two factors. The first factor is papaya seeds compare with jackfruit (K) that 50g: 100g (K1), 75g: 75g (K2), and 100g: 50g (K3). The second factor is roasting duration 12 minutes (L1), 14 minutes (L2), and 16 minutes (L3). Testing of antioxidant activity with DPPH (1,1-diphenyl-2-picrylhydrazyl) by means of UV-Vis Spectrophotometer at a wavelength of 520 nm. The test results are the highest antioxidant activity in treatment K3L1 by 95.19% and the lowest in treatment K1L3 of 86.77%. Data were analyzed by analysis of variance SPSS two lanes (Two Way Anova) shows the influence of two factors on the quality of coffee products.
