【 摘 要 】

Papain enzyme and carboxyl methyl cellulosa was used in tofu production as coagulant and thickener. Papain enzyme is a protease enzyme that can break proteins. Papain enzymeuseful as coagulant to replace acid and base coagulant. The goal of this study is to observe papain enzyme as coagulant and carboxyl methyl cellulose as thickener to increase characteristic of tofu. Tofu is from soy milk has been pasteurized at 70 °C with the addition of papain enzyme and carboxyl methly cellulose. The concenration of papain enzyme is varied such as 200, 400, 800, and 1000 ppm. After Temperature reachs at 90 °C, carboxyl methyl cellulosa is added in soy milk to produce tofu. This study focuses on introducing papain enzyme as coagulant as well as investigating its potential in improving tofu making process productivity. Further the present work attempts to determine the synergistic effect of combining CMC/enzyme in tofu characteristic. This research was conducted with soy milk pasteurized at 70 °C with increasing papain enzyme. Protein from tofu was determined by using Spectrophotometer UV-VIS Shimadzu UV-1800 type. The highest protein concentration of the papain enzyme was found in 1000 ppm with CMC concentration of 0.6% w/v and based on organoleptic tests that the adding CMC and enzyme papain does not effect the taste, smell, texture and color of tofu. The taste of tofu produced is similar to the taste of tofu in the market.
