Effect of non
Non-enzymatic browning reactions have a considerable impact on the characteristics and quality of thermally processed malt One of the obvious negative consequences is the loss of nutritive value This loss is attributed to decrease of digestibility destruction and/ or biological inactivation of amino acids inhibition of proteolytic and glycolitic enzymes and interaction with metal ions (4 5
Enzymatic Browning
Enzymatic browning can be prevented by application of several methods These methods are mostly targeted to inactivate the enzyme and remove oxygen from the product Blanching is one of the most effective methods to control enzymatic browning It involves application of heat for short term to destroy the activity of the enzyme before freezing or storing fruits and vegetables Refrigeration

The Lack of Enzymic Browning in Wild Potato Species
The cause of this enzymatic browning of cut surfaces external bruising and bla~spot caused by internal bruising is well understood and is due to the oxidation of phenolic substrates sum as tyrosine and possibly mlorogenic acid by the enzyme polyphenol-oxidase to dark melanin pigments (MUNETA 1977 GRAY and HUGHES 1978) It is assumed that the enzyme and substrate are held separately in vivo

Accelerated glucose discoloration method
The non-enzymatic browning of glucose was investigated by accelerating the glucose degradation with or without heating glucose solutions for 1 h at 100C with different reagents Evaluation of the glucose degradation was performed using two types of glucose glucose A and glucose B in order to investigate the influence of the glucose manufacturing process on glucose discoloration
Effect of Ingredients on Non

Vitamin C Effect on Apple Browning
The non-enzymatic browning may have produced end products which also caused absorption at 420nm As ascorbic acid affects non-enzymatic browning the higher ascorbic acid concentration at 100 mg contributes to more non-enzymatic browning than that at 80 mg contributing to a slightly higher browning index [1] Evaluation
