1. Maltol has three main methods:
1. The extraction of maltol from natural products is found in the decomposition solution of wheat and soybean and the roasting of barley, and also in some fir trees and deciduous pines. In 1986, the United States extracted malt alcohol from wood vinegar using extraction crystallization. In 1970, the United States used chloroform to extract maltol from larch bark. The Japanese extract from the leaf of the incense leaf or extract from its steam distillation. The wood tar derived from wood distillation can also be separated into maltol.
2. The parent of the semi-synthetic method is glucose, which is equivalent to the dehydration product of 3- ketone – glucose. Starch with yellow aspergillus fermentation, the fermentation liquor of kojic acid, classics into kojic acid under the catalytic oxidation with air (oxygen) into a stuffy acid, and then under the 225 ℃ decarboxylation coking with acid. In the alkaline condition, the pyrogallic acid reacts with the formaldehyde to produce hydroxymaltol. The maltol was then reduced with hydrochloric acid and zinc powder. After distillation or sublimation, recrystallization in chloroform, the finished product of malt alcohol. It can be made from kooic acid, and it can be formed by dioxic acid and benzyl chloride, and then it is oxidized by manganese dioxide to sulfuric acid ether, and then the benzyl group is produced by sulfuric acid.
This product is synthesized from furfural extract of agricultural products, and has more than 88% biological activity. It is a kind of widely used fragrance, which can also be used for sweetening, aroma synthesis, fragrance improvement and determination of incense. It has the effect of reducing acid, suppressing bitterness, going to the fishy and stimulating. This product is easy to dissolve in hot water, ethanol, glycerin and chloroform, mainly used for food fragrance, daily fragrance and tobacco flavor, photosensitive materials, preservatives and skin care products. One portion of maltol is substituted for four coumarins.
