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...

Biochemical analysis of amylose-extender (ae) mutant of rice (Oryza sativa) revealed that the mutation in the gene for starch-branching enzyme IIb (BEIIb) specifically altered the structure of amylopectin in the endosperm by reducing short chains with degree of polymerization of 17 or less, with the greatest decrease in chains with degree of polymerization of 8 to 12. The extent of such change ...

Starch was preirradiated with cobalt-60 and then allowed to react with mixtures of acrylamide and N,N,N-trimethylaminoethyl methacrylate methyl sulfate (TMAEMA' MS) in a water solution. The graft copolymers resulting were purified and characterized, and the influence of a number of irradiation and reaction variables on graft copolymer composition was determined. Although the reaction of irradia...

Fast-dissolving drug-delivery systems are considered advantageous over the existing conventional oral dosage forms like tablets, capsules, and syrups for being patient friendly. Buccal films are one such system responsible for systemic drug delivery at the desired site of action by avoiding hepatic first-pass metabolism. Metformin hydrochloride (Met), an antidiabetic drug, has poor bioavailabil...

Hydrocarbons are the organic contaminants that enter the environment through natural and anthropogenic processes. Microbial degradation of hydrocarbons is considered as cost effective treatment option. The mass transfer between hydrocarbons to catabolic microflora is highly influenced by its lower aqueous solubility that limits the biodegradation rates. Cyclodextrins with its interior hydrophob...

Mixtures of cereals and legumes result in products with higher content of high biological value proteins. The thermoplastic extrusion promotes the transformation of chemical, physical and nutritional characteristics of the food such as starch gelatinization and promotes the inactivation of anti-nutritional compounds and enzymes. This study aimed to develop products extruded using broken rice an...

BACKGROUND Dietary fibers contribute to health and physiology primarily via the fermentative actions of the host's gut microbiome. Physicochemical properties such as solubility, fermentability, viscosity, and gel-forming ability differ among fiber types and are known to affect metabolism. However, few studies have focused on how they influence the gut microbiome and how these interactions influ...

Given recent worldwide environmental concerns, biodegradability, antibacterial activity, and healing properties around the wound area are vital features that should be taken into consideration while preparing biomedical materials such as dressings. Some of available dressings present some major disadvantages. For example, low water vapor transmission rate (WVTR), inadequate exudates absorption,...

Durian (Durio zibethinus Murr.) is one of the authentic tropical fruits in Indonesia with a high popularity for consumption by public. Many local varieties are originating from North Sumatra, which Bintana variety as major cultivar Medan City. Like other fruits, durian seeds mostly neglected and disposed only wastes. It reported that starch content may be utilized converted into valuable produc...

Biopolymer films have an increasing share in the packaging material sector due to a number of advantages: availability, cheapness, easy processing, degradability, etc. On other hand, numerous methods been developed optimize their unfavorable properties (weaker mechanical characteristics, hydrophilicity, etc.). This paper examines influence synthesis method on starch-gelatin properties. The film...
