Abstract

Sweat potato can be processed to be several of food products. One of the products is sweat potato syrup, especially violet sweat potato which is including pigment anthocyanine. The objective of research was to know the effect of sugar concentration and carboxy methyl cellulosa (CMC) on the characteristic of sweat potato syrup. The experiment used randomized Complete design (RAL) with factorial block consist of sugar concentration 50, 60, 70 and 80% and adding carboxy methyl cellulose, 0, 0,5, 1,0 and 1,5%. Result of research showed that the adding of sugar concentration 60 percent and carboxy methyl cellulosa 1,5 percent produce the best characteristic of sweat potato syrup with criteria such as total soluble solid 75,60 % brix, viscosity 11,66 cp, vitamin C 0,44 mg/100g, anthocyanine content 11,15 mg/100g and total of fungi 50 Cfu/ml. All of characteristic as well as according to Indonesian standardization code (SNI-01- 3544-1994).

Abstract

Wine is ethanol fermented production by Saccaromyces cereviceae on the severely sugar of grape fruit and other some fruit. Wine was involved cluster of alcoholic’s drink of B classification in Indonesian Standardization code with range alcoholics 5 to 20% which is consideration by the Indonesian Healthy Ministry. The research was aimed to know the effect of starter concentration on ethanol production and wine characteristic of several sweat potato. The experiment used factorial design consist of starter concentration 5%, 10% and 15% while several of sweat potato such as white color sweat potato, yellow color sweat potato and purple color sweat potato. Result of research showed that white color sweat potato and adding 15% starter produced the total of ethanol 16,65% v/v, While the sensory tested indicated that purple color sweat potato and 15 % starter produced the best characterization of wine with the criteria purple colorizes, specific odor and flavor were accepted by panelist. The treatment is also supported by 15 % starter to produce wine with the criteria purple colorizes, specific odor and flavor and all accepted by panelist. The treatment is also supported by pH 3,42, TSS 6,05% brix, total of acetic acid 0,0825% b/v, total of anthocynine 22,92 mg/100g, ethanol content 10,90%, total of fungi 2,20x104cfu/ml. All of the characteristic of wine as well as according to the Indonesian standardization code (SNI-01-4018- 1996). Panelist tested showed that wine preferred
