Cellulose hydrogel was produced from pretreated oil palm empty fruit bunch fiber (EFB) that went through acid hydrolysis and thermal hydrolysis. The pretreated EFB was dissolved in LiOH/urea aqueous solution using the rapid dissolution method and was subjected to a crosslinking process with the aid of epichlorohydrin to form hydrogel. The effects of both hydrolyses’ time on average molecular we...

lipase from candida antarctica, fixed on macroporous acrylic resin, has been used for the intermediate production of mono- and diolein by hydrolysis of triolein. the effect of altering concentrations of triolein and glycerol and the function of the molecular sieve on the hydrolysis reaction of triolein were investigated. the highest hydrolysis yield was observed for the utmost concentration of ...

Swamp eel ( Monopterus albus ) processing produced byproducts such as heads that possess a high protein, carbohydrate, lipid, and energies content. were hydrolyzed (SEHPH) tested for their antibacterial activity against histamine-producing bacteria (HPB) to explore the potency. The hydrolysis was conducted by commercial papain enzyme PAYA (concentration 4%) with various times (0, 60, 120, 180 m...

Cholesterol with high levels in blood vessels can cause atherosclerosis, stroke, and sudden heart attack. Isolates soy protein have bioactive peptides that the potential as anticholesterol. This research aims to determine optimum conditions of hydrolysis characterize from isolate hydrolysates by bromelain enzyme. Hydrolysis optimization conducted using enzyme 0,2%; 0,5% (w/v) variation incubati...

Background and objectives For most of the application cereal materials, sample pretreatments are considered critical factors. Different (roasting amylase hydrolysis) prior to extraction were employed obtain oat protein (OP) from grains. The effect pretreatment on structure functional properties OPs was determined. Findings Analysis sodium dodecyl sulfate–polyacrylamide gel electrophoresis (SDS-...

Abstract Threadfin bream ( Nemipterus sp .) is a demersal fish that widely distributed in Indonesian waters. Protein content of 16.85% and fat 2.2%. High protein low-fat make potential as raw material for hydrolysate. The purpose this study was to determine the effect differences papain enzyme concentration, temperature, duration hydrolysis process on degree optimal time using Response Surface ...

The Lamuru fish (Caranx ignobilis) is mostly found in tropical waters of the indo-pacific region, namely Indonesia. It believed to contain collagen and this study aims isolate from its bone determine collagen’s antioxidant ?-glucosidase inhibitory activity. In our study, was extracted using acetic acid which hydrolyzed by collagenase enzyme Clostridium histolyticum at a temperature 37 °C, pH 7....
