Purpose – Infant formula is the sole nutrition and food source for many infants. Information on the free amino acid (FAA) content of formulas, particularly those that are protein hydrolysate based, is limited, despite emerging evidence for the role of FAAs in regulating eating behaviour. The purpose of this paper is to measure levels of essential, semi-essential, and nonessential FAAs in commer...

BACKGROUND Microbial bioconversion of photosynthetic biomass is a promising approach to the generation of biofuels and other bioproducts. However, rapid, high-yield, and simple processes are essential for successful applications. Here, biomass from the rapidly growing photosynthetic marine cyanobacterium Synechococcus sp. PCC 7002 was fermented using yeast into bioethanol. RESULTS The cyanoba...

Ingestion of whey hydrolysate, casein, or soy protein isolate: effects on mixed muscle protein synthesis at rest and following resistance exercise in young men. J Appl Physiol 107: 987–992, 2009. First published July 9, 2009; doi:10.1152/japplphysiol.00076.2009.— This study was designed to compare the acute response of mixed muscle pro...

In this study, marine tunicate Styela clava hydrolysate was produced by an environment friendly and green technology, pressurized hot water hydrolysis (PHWH) at different temperatures (125–275 °C) and pressure 50 bar. A wide range of physico-chemical and bio-functional properties such as color, pH, protein content, total carbohydrate content, reducing sugar content, and radical scavenging activ...

BACKGROUND The production of value-added chemicals alongside biofuels from lignocellulosic hydrolysates is critical for developing economically viable biorefineries. Here, the production of propionic acid (PA), a potential building block for C3-based chemicals, from corn stover hydrolysate is investigated using the native PA-producing bacterium Propionibacterium acidipropionici. RESULTS A wid...

An investigation on antioxidative properties of different molecular weight fractions protein hydrolysate produced from Common carp (Cyprinus carpio) head

The expediency of processing whey is confirmed by the value its composition, amount raw materials, and possibility obtaining a wide range food products ingredients based on it. most appropriate technological method for reducing antigenicity proteins in industry enzymatic hydrolysis. work aims to study chemical composition properties hydrolysis cheese UF concentrate with enzyme preparations Prom...

Two fractions (50-K and permeate) from a proteolytic hydrolysate (degree of hydrolysis, DH=3.8 %) of wheat gluten were separated using ultrafiltration (UF) membrane with molecular mass cut-off of 50 kDa. The effects of the wheat gluten hydrolysate (WGH) and its UF fractions on the mixing behaviour and viscoelastic properties of wheat dough were presented. The WGH and its UF fractions modified t...

Calf thymus DNA was reacted with 1,2-epoxybutene (BDO) in phosphate buffered saline at 37 degrees C for 12 h. DNA was ethanol precipitated and hydrolyzed with 1 M HCl to release DNA bases. Adenine (A)-BDO and guanine (Gua)-BDO adducts were analyzed in the ethanol supernatant and DNA hydrolysate using LC/ESI MS/MS. Reaction of BDO with A resulted in the formation of seven A-BDO adducts with MH+ ...

In the present study, we investigated to the antioxidant and angiotensin I-converting enzyme (ACE) inhibitory activities of the northern shrimp (Pandalus borealis) by-products (PBB) hydrolysates prepared by enzymatic hydrolysis. The antioxidant and ACE inhibitory activities of five enzymatic hydrolysates (alcalase, protamex, flavourzyme, papain, and trypsin) of PBB were evaluated by the 2, 2′-a...
