Yu A.-N., Tang L.-P. (2016): Kinetics of non-enzymatic browning reaction from the l-ascorbic acid/l-cysteine model system. Czech J. Food Sci., 34: 503–510. The kinetics of the non-enzymatic browning reaction from l-ascorbic acid/l-cysteine model systems was investigated at 125–155°C for 10–120 min by measuring the loss of reactants and monitoring the brown colour development. The result showed ...

Browning is the result of appearance of dark colored pigments formed by enzymatic and non enzymatic reactions. In this review AA, first overview the biochemistry of browning and fruits response and protection, successively touch the topic in the lightly processed fruits. Non enzymatic reaction is mainly due to Maillard reaction compounds in which concentration of amino acid (nitrogen supply) an...

Alternate strategies for prevention of enzymatic browning of fruits and vegetables are required by food industries due to restrictions and several negative health attributes of sulphites, which are effective inhibitors of enzymatic browning reaction. These reactions result mostly from polyphenol oxidase (PPO). The present study was conducted to evaluate the antioxidant and PPO inhibitory potent...

Ascorbic acid and fructose react in an aqueous alkaline solution at temperature below 50°C in a Maillard-type reaction to from brown coloured end products. The kinetics of browning of alkaline solution of fructose in presence of ascorbic acid has been studied by measuring the absorbance of browning development in the reaction. The development of brown colour due to heating of either reducing su...

2 Introduction The reaction between sugars and amino groups was first described in 1908 by two Englishmen, Ling & Malting, who considered color formation in beer. In 1912 Louis-Camille Maillard described a browning reaction between reducing sugars and amino groups. Despite not being the first to report the reaction, Maillard was the first to realize the significance of the reaction in areas as ...

Glycation is the reaction between amino residues of proteins and carbonyl of reducing sugars. French Louis Camille Maillard discovers this reaction from the browning reaction by amino acid and sugar, and it is widely known for the food chemistry as the Maillard reaction. The hemoglobin A1c (HbA1c) measured all over the world as a marker of glycemic control is equivalent to the Amadori rearrange...
