Physical and Chemical PropertiesThere are two kinds of α-type and β-type, the former melting point 108 ℃,[α]D20=+173 °; The latter melting point 102~103 ℃,[Α] D20 was 130.4 °. Reductive (capable of reducing the Ferrin solution). Sweetness is about 30% of sucrose, sweet mild. The ability to prevent oxidation of vitamin C is greater than that of other sugars. The antibacterial ability was stronger than that of sucrose (the inhibitory concentration of sucrose was more than 60%, maltose was more than 40%), and it was not easy to Browning.

D-MALTOSE - Introduction

There is an aldehyde group reaction, a silver mirror reaction can occur, and it can also be co-heated with Ban's reagent (prepared with copper sulfate, sodium carbonate or caustic soda, sodium citrate and other solutions) to generate brick red cuprous oxide precipitate.

D-MALTOSE - Reference Information

NIST chemical information information provided by: webbook.nist.gov (external link)
properties a viscous slightly transparent liquid, without visible impurities, light yellow to brown yellow, with the normal odor of sugar, pure taste, no smell.
Introduction sugar is based on sorghum, rice, barley, millet, corn and other starchy grains as raw materials, after fermentation saccharification made of food, also known as "," glue. Mainly containing maltose, and contains vitamin B and iron. There are soft and hard, the soft is yellow-brown viscous liquid; The hard is soft sugar after stirring, mixed with air and solidified, which is a porous yellow-white sugar block. Soft sugar is preferred for medicinal use. Sweet, warm. Can make up for the emergency, moistening the lungs and relieving cough, detoxification. Dissolve the drink, into the soup, the pharynx, or into the candy. Damp heat in spleen and stomach, moderate nausea and vomiting were not suitable. [Performance] sweet, warm. Can make up for the emergency, moistening the lungs and relieving cough, detoxification.
Use sugar for spleen and stomach weakness, acute Abdominal Pain; Lung dryness Cough, sore throat.
sweetener; Moisture absorbent. More for low sweetness of food, although the sweetness is reduced, but the concentration is unchanged, it can inhibit the reproduction of microorganisms and achieve the purpose of long-term preservation. The use of its moisture absorption can prevent the crystallization of candy, but also can improve the food structure, so that long-term keep soft, also applies to the natural fruit juice sweetening.
nutritive sweetener.
can be used to analyze test controls.
scientific research and experiment. There are aldehyde groups in the molecular structure of maltose, which is a reducing sugar. Therefore, it can react with silver ammonia solution by silver mirror, and can also react with new Alkaline copper hydroxide to generate brick red precipitate. Two molecules of glucose can be produced by hydrolysis under certain conditions. Used as biological medium, polysulfide Determination Agent, analytical chemistry Colorimetric Determination of standard Brown high maltose syrup in addition to cold drinks and baked goods are widely used, it is also widely used in medicine and health food. The low osmotic pressure of high maltose can be used instead of glucose for the infusion of patients, and the intravenous infusion of pure maltose is not easy to cause the increase of blood sugar. Because maltose syrup can penetrate into the body of the fetus, it can be used to protect the fetus of pregnant women at risk. In traditional Chinese medicine, high maltose syrup can fill the deficiency of the lung, the indications of the deficiency of Abdominal Pain, lung dryness Cough and so on.
maltose has an aldehyde group in its molecular structure, which is a reducing sugar. Therefore, it can react with silver ammonia solution by silver mirror, and can also react with new Alkaline copper hydroxide to generate brick red precipitate. Can be hydrolyzed under certain conditions to produce two molecules of glucose used as biological medium, polysulfide assay, analytical chemistry Colorimetric Determination of standard Brown.
preparation method is a sweet product prepared by using rice and other cereals as raw materials and the action of malt saccharification enzymes. Later, the gradual use of starch instead of rice production of sugar, the big is the era began to use activated carbon decolorization production of refined sugar. After the development of Europe and the United States with acid saccharification method to produce sugar, its flavor and heat resistance (boiling temperature) is better than the malt method. Japan also has a powder sugar production process is the use of spray drying method of dehydration of sugar powder.
production method with grain and potato starch as raw material, through enzymatic or acid hydrolysis method, liquid glucose and fructose syrup, etc.
starch is used as raw material, firstly liquefied by amylase, and then saccharified by β-amylase. The purity can reach more than 97%. Generally used barley malt (containing amylase) on the role of starch, dextrin and maltose (about 1/3) mixture, called Sugar.
