Response surface optimization of acid modification on mung bean starch
ثبت نشده
چکیده
This research shows the dependence of number average degree of polymerization (DPn) of mung bean starch (MBS) on starch slurry concentration, acid/starch slurry ratio, time and temperature in acid modification process. Optimizing these factors to earn as low as possible DPn was evaluated by using the Response Surface Methodology (RSM) with reduced Central Composite Face-Centered (reduced CCF) model. Optimal result is DPn of 795.6 (y) with 29.76% starch slurry (x1), 4.9:1 acid/starch slurry ratio (x2), treating in 120 min of time (x3) and 47.2oC of temperature (x4). Pasting viscosity of MBS decreased after the treatment and DE (dextrose equivalent) was not detected.

Intake of Mung Bean Protein Isolate Reduces Plasma Triglyceride Level in Rats
Background: Mung bean is well known as a starch source, but the physiological effects of mung bean protein have received little attention. In this study, we isolated mung bean protein from de-starched mung bean solutions, and investigated its influence on lipid metabolism. Objective: The aim of this study is to clarify the influence of the lipid metabolism by consumption of mung bean protein is...

Objectives: This study aims to improve and expand the performance of carboxy methyl mung bean starch (CMMS) as a gelling agent and an oil-inwater (o/w) emulsion stabilizer via cross-linking reaction with dichloroacetic acid (DCA). Methods: Mung bean starch was carboxymethylated with chloroacetic acid and subsequently cross-linked with 0.1-10% DCA. Fifteen cross-linked carboxy methyl mung bean s...
متن کاملEffect of Heat-Moisture Treatment on the Formation and Properties of Resistant Starches From Mung Bean (Phaseolus radiatus) Starches
Mung bean starches were subjected to heat-moisture treatment (HMT) by different moisture contents (15%, 20%, 25%, 30% and 35%) at 120°C for 12h. The impact on the yields of resistant starch (RS), microstructure, physicochemical and functional properties was investigated. Compared to native starch, the RS content of heat-moisture treated starches increased significantly. The RS level of HMT-20 w...
متن کاملEvaluating the optimization of irradiation components of mung bean seeds with ultrasound for increased seedling vigor, using artificial neural network
Extended Abstract Introduction: A large number of experimental evidence indicates the positive effect of irradiating the seed with ultrasonic waves; so that irradiation causes the production of a more vigorous seedling. Conversely, inappropriate intensity and duration of irradiation can impose deleterious effects on seedlings by damaging the enzymatic activity. There are complex inter-and in...
متن کاملHydrolysis of granular starch at sub-gelatinization temperature using a mixture of amylolytic enzymes
Native granular starches (corn, cassava,mung bean, and sago) were hydrolyzed using amixture of alpha-amylase and glucoamylase at 35 ◦C for 24h. Hydrolyzed starches were analyzed for the degree of hydrolysis and for physicochemical and functional properties. Corn starch showed the highest degree of hydrolysis, as evidenced by the presence of distinct pores penetrating deep into the granules. Enz...
