The influence of the composition and method preparation gelatinized starch compositions on their relative viscosity is studied. activation energy viscous flow developed formulations was determined. change in polymer dressing from time to

The purpose of this study was to assess the properties of resistant starch (RS) III prepared from elephant foot yam starch using pullulanase enzyme. Native and gelatinized starches were subjected to enzymatic hydrolysis (pullulanase, 40 U/g per 10h), autoclaved (121°C/30 min), stored under refrigeration (4°C/24h) and then lyophilized. After preparation of resistant starch III, the morphological...

microencapsulation as one of the most modern methods has remarkable effects on probiotic survival. in this study lactobacillus casei (atcc 39392) and bifidobacterium bifidum (atcc 29521) were encapsulated using calcium alginate-gelatinized starch, chitosan coating and inulin via emulsion technique, and were incubated in simulated gastric juice (along with pepsin, ph=1.5) and simulated intestina...

The effects of sucrose on the physical properties of cassava starch aqueous systems were investigated at varied concentrations of cassava starch (5-15% w/w) and sucrose (0-40% w/w). The peak viscosity and the final viscosity during a gelatinization-retrogradation cycle were determined based on a Rapid Visco Analyzer (RVA) test. Sucrose generally increased the viscosity values, while such increm...

Flour and starch isolated from the tubers of Scirpus grossus were investigated for their physicochemical properties and starch digestibility. The flour was extracted using two different processes namely peeled and unpeeled processes. Proximate analysis revealed that the flours from both processes contain considerably high total starch, more than 80%, which indicate their potential use as starch...

Cassava starch is a main renewable bio-resource with low price and mass production in Guangxi, China. It was used as carbon source in growing Xanthomonas campestris pv. campestris 8004 (Xcc 8004) for xanthan gum production in this study. The xanthan gum yield of gelatinized cassava starch was higher than that of raw cassava starch; the maximal reducing sugar and amylase activity reached 14.30 g...

The effect of gelatinization of dietary starch (wheat, corn and potato) on the distribution of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase along the small intestine of rats was studied in villus and crypt cell populations isolated by graduated scraping. Gelatinized starch preferentially stimulated jejunal reductase activity in both villus and crypt cells and consequently retained ...

Bio-degradable cassava starch-based adhesives were produced from chemically gelatinized starch formulations. The varying combinations of process parameters applied include: concentration gelatinization modifier, mass % borax/starch, and temperature reaction mixture. physico-chemical for characterizing the adhesive samples viscosity, density, pH bonding strength. effects variation on quality ass...

An important application of starch grafted with copolymers from unsaturated organic acids is the use as water absorbent. Although much research has been published in recent years, the kinetics of water absorption and the swelling behavior of starch based superabsorbents are relatively unexplored. Also, water retention under mechanical strain is usually not reported. Cassava starch was used sinc...
