In the current study, the relationships between functional properties and average molecular weight (AMW) of collagen hydrolysates from Spanish mackerel (Scomberomorous niphonius) skin were researched. Seven hydrolysate fractions (5.04 ≤ AMW ≤ 47.82 kDa) from collagen of Spanish mackerel skin were obtained through the processes of acid extraction, proteolysis, and fractionation using gel filtrat...

OBJECTIVE Evaluation of the efficacy and safety of a food supplement made of collagen hydrolysate 1200 mg/day versus placebo during 6 months, in subjects with joint pain at the lower or upper limbs or at the lumbar spine. DESIGN Comparative double-blind randomized multicenter study in parallel groups. SETTING 200 patients of both genders of at least 50 years old with joint pain assessed as ...

Zhang Y., Zhao X.-H. (2013): Properties of casein hydrolysate as affected by plastein reaction in ethanol-water medium. Czech J. Food Sci., 31: 559–567. Casein hydrolysate with in vitro ACE-inhibitory activity of 44.4% at 0.3 mg/ml was generated from casein by Alcalase and modified by the Alcalase-catalysed plastein reaction in an ethanol-water medium. Eight treated hydrolysates were prepared u...

This work evaluates the possibility of applying enzymatic beech wood (Fagus sylvatica) hydrolysate as a feedstock for Chlorella sorokiniana growth, and fatty acid and pigment production. Beech wood solids were pretreated with NaOH at high temperature to partially remove xylose and Klason lignin, and enable production of glucose during subsequent enzymatic hydrolysis. Neutralized wood enzymatic ...

BACKGROUND Lignocellulosic biomass has long been recognized as a potential sustainable source of sugars for biofuels. However, many physicochemical structural and compositional factors inhibit the enzymatic digestibility of the lignocellulosic biomass. In this study, efficient pretreatment method of rice straw (RS) was developed and the RS hydrolysate was applied in the cultivation of microalga...

BACKGROUND The use of lignocellulosic constituents in biotechnological processes requires a selective separation of the main fractions (cellulose, hemicellulose and lignin). During diluted acid hydrolysis for hemicellulose extraction, several toxic compounds are formed by the degradation of sugars and lignin, which have ability to inhibit microbial metabolism. Thus, the use of a detoxification ...

26 Dietary collagen hydrolysate has been hypothesized to improve skin barrier function. To 27 investigate the effect of long-term collagen hydrolysate administration on the skin, we 28 evaluated stratum corneum water content and skin elasticity in intrinsically aged mice. 29 Female hairless mice were fed a control diet or a collagen hydrolysate-containing diet for 30 12 weeks. Stratum corneum w...

Modulating α-amylase enzyme activity with bioactive peptides of protein hydrolysate is one of a viable strategy in the management of diabetes through the control of postprandial glucose level. In this study, four proteolytic enzymes (pepsin, neutrase, alcalase and trypsin) were used to investigate the in vitro α-amylase inhibition of dried laver seaweed (Porphyra species) protein hydrolysates. ...

Wheat straw hemicellulosic hydrolysate was used for xylitol bioproduction. The use of a xylose-containing medium to grow the inoculum did not favor the production of xylitol in the hydrolysate, which was submitted to a previous detoxification treatment with 2.5% activated charcoal for optimized removal of inhibitory compounds.
