The use of protein hydrolysates for the development of new food products requires their prior characterization including the determination of the degree of hydrolysis (DH) and the distribution of pept...
Maillard Reaction (MR) is a complicated non-enzymatic browning which can happen in many kinds of food, processed products such as breweries, dairy products and sugar products. Studies have done in ord...
HPLC with amperometric detection was used to evaluate the reducing power of 23 beers and aqueous extracts of 17 barley malts. While brew pale malts were only slightly higher in electrochemical reducin...
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...
Taking into account the impact of monitoring food adulteration on the quality of food products, the aim of this study was to use polymerase chain reaction technology to detect possible adulteration of...
Based on the known approaches and published mathematical models, as well as on theoretical consideration using our experimental data, the integrated approach to mathematical modelling of atrazine bi...
An aqueous ribose-cysteine model system, heated at 140°C under supercritical carbon dioxide (SC-CO2) and supercritical nitrogen (SC-N2), was investigated with emphasis on the formation of volatile com...
利用木瓜蛋白酶对酪蛋白水解,并对所得到的水解物进行类蛋白反应修饰,制备高活性抗氧化肽。以水解物的游离氨基含量变化为响应值,利用响应面分析法对类蛋白反应条件进行优化,得到适宜条件为:酶添加量为500U/g,温度30℃,底物质量分数50%,反应时间5.6h。毛细管电泳分析确认,水解物经类蛋白反应修饰后肽分子组成发生变化。抗氧化活性分析结果表明,所制备的3个修饰产物对3种自由基的清除能力显著提高。
We devised a simple and efficient method of preparing chromosomal DNA from Gram-positive bacteria for use as a template in PCR, which consists of achromopeptidase treatment followed by Chelex 100 trea...
Maillard reaction occurs extensively in food systems and in vivo. In an intermediate Maillard reaction of proteins with glucose, 3-deoxyglucosone (3DG) was generated from Amadori compounds in an early...
Effect of direct current on soymilk coagulation was studied to establish a new processing method for food. Soymilk was treated with direct electric current (60 mA) in an anode chamber. The treated soy...
To obtain basic information on the effect of the dissociation of L-ascorbic acid (AsA) on its radical scavenging ability, 1,1-diphenyl-2-picrylhydrazyl (DPPH) was used in both homogeneous and heteroge...
The browning reaction in barley products after boiling or steaming is undesirable in human food. We estimated the degree of browning reaction—the browning index (BI)—by the difference in the Hunter’s ...
The effect of the combination of heating and pressurization on Maillard reaction was investigated using a model solution of glucose and glycine, and a white sauce. The apparent browning rates were cal...
Black tea accounts for almost 80% of the world’s tea production and is the most important source of polyphenol in the world. However, little has been known about the chemistry of black tea polyphenols...
