Abstract

Cassava is one of the Indonesian local commodities. Cassava contains a high amount of starch which can be used as an alternative to gelatin in making marshmallow. This study aimed to analyze: 1) the enzymatic process of starch modification using α-amylase, 2) the effect of incubation time and enzyme concentration on the yield of maltodextrin which close to gelatin, and 3) to utilization of cassava starch maltodextrin as an ingredient of marshmallow product. The result showed that application of marshmallow gelatin substitution using cassava starch has been done. There were three ways of cassava starch hydrolysis, one of them is enzymatic hydrolysis using α-amylase which produces of maltodextrin. This enzyme was an endoamylase that cleaves the α-1,4 glycosidic linkage of the amylose or amylopectin chain. Besides, Bacillus amyloliquefaciens was one of the microbes that can produce α-amylase with good thermostability, about 100-110°C. The exact enzyme concentration and incubation time of starch hydrolysis could produce maltodextrin optimally. However, maltodextrin as a foaming agent and the prevention of crystalline formation had functional properties that approach gelatin, so it can be concluded that maltodextrin was developed further as an alternative to the use of gelatin in marshmallow products.

Abstract

This research aims to study gelatinization profile and physical properties of ripe and overripe canistel flour. Data statistically analyzed using the independent sample T-tes. Analyzed of the chemical properties of canistel fruits include water content, starch content, and sugar content, while analyzed canistel flour includes gelatinization profile, shape and size of starch granules with color test. The results of the analyzed showed that the water content and sugar content of ripe canistel fruit is higher than those of overripe canistel fruit, while the lower starch content. The total starch and amylose content of ripe canistel flour is higher than that of overripe flour. Analyzed the results of gelatinization profile ripe canistel flour has a peak viscosity, final viscosity, and  higher gelatinization temperature than the finished canistel flour and the gelatinization faster time. Analysis of the physical properties of the color parameters of canistel flour produces the reddish yellow color, while of the shape and size of the canistel flour starch granule shape that are round with size ranges between 2-7 µm.Keywords: Canistel fruit, canistel flour, gelatization profile.
