Abstract

Liquid sugar is a sweetener that is widely used in the food industry. Apart from starch, liquid sugar can be produced from cellulose hydrolysis by using cellulase enzymes. This study aims to obtain the best concentration of cellulase enzymes in the production of cellulose liquid sugar in the skin of red dragon fruit. The production of liquid sugar uses the method of hydrolysing enzymes of different concentrations (1%,2%,3%). The results showed that there was no significant influence on the characteristics of liquid sugars resulting from the addition of three different enzyme concentrations. The observed characteristics are total sugar content, water, ash content, viscosity and color. Enzyme concentration of 3% is the best liquid sugar based on observations of total sugar content and color.

Abstract

Keribang tubers are a prospective local food and can be used as food for claims and food diversification. Anthocyanins from keribang tubers can be processed into food products, one of them is made into jam. Jam is a food product with a gel consistency, therefore a thickening agent such as Carboxyl Methyl Cellulose (CMC) is needed. The purpose of this study was to determine the effect of adding CMC and heating time as well as the best combination to the physicochemical characteristics of keribang tuber jam. This research design used a Randomized Block Design (RAK) with two treatment factors, consisting of 3 treatments of CMC (0.5%; 0.75%; and 1%) and 2 treatments of heating time (15 minutes and 20 minutes), with 4 replications. Parameters observed were water content, total polyphenols, total dissolved solids, antioxidant activity, smearing power, and organoleptic tests. The best treatment was tested using the effectiveness index test. The results showed that CMC concentration treatment and heating time did not significantly affect the water content, total dissolved solids content, antioxidant activity, and spread ability, but significant on the total polyphenol content value in keribang tubers jam. The organoleptic test showed that the panelists preferred the keribang tubers jam with a CMC concentration of 0.5% and a heating time of 15 minutes in terms of color and texture. Based on the effectiveness index test, the best treatment for keribang tubers jam was 1% CMC concentration and 20 minutes of heating time
