Kinetics of Non-Enzymatic Browning Reaction from the l-Ascorbic Acid/l-Cysteine Model System
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 ...
متن کاملTopical L-ascorbic acid: percutaneous absorption studies.
BACKGROUND Reactive oxygen species generated by ultraviolet light result in photocarcinogenic and photoaging changes in the skin. Antioxidants protect skin from these insults. OBJECTIVE This study defines formulation characteristics for delivering L-ascorbic acid into the skin to supplement the skin's natural antioxidant reservoir. METHODS L-ascorbic acid or its derivatives were applied to ...
متن کاملInfluence of vegetable amino acids and oils supplementation of on Chlorella vulgaris amino acid profile
The aim of the present research is to investigate the profile of amino acid of Chlorella vulgaris supplemented with some plant amino acid and oil extracts. The bioactive oil and amino acid from four Iranian medicinal plants, namely Oliveria decumbens, Thymus kotschyanus, Trachyspermum ammi, and Zataria multiflora were obtained. The LC-MS / MS analysis demonstrated that the major amino acids com...
متن کاملEffect of L-cysteine, Potassium Metabisulfite, Ascorbic Acid and Citric Acid on Inhibition of Enzymatic Browning in Longan
The effect of different anti-browning agents on partially purified longan polyphenol oxidase (PPO) activity was investigated by spectrophotometry, using catechol as a phenolic substrate. For this purpose, L-cysteine, potassium metabisulfite, ascorbic acid, and citric acid were used to inhibit the activity of longan PPO at different concentrations (0-10 mM). Lcysteine was found to be the most po...
متن کاملKinetic behaviour of ascorbic acid - fructose browning reaction in alkaline medium
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...
