Maltose is made of crystal, as Sweeteners
But, sugar sweet reached only 1/3. Maltose is a cheap, nutritious food, easy digestion and absorption by the body.
Malt dust Related food
It is made of glutinous rice and wheat, sweet and delicious, nutrient rich, with Jianweixiaoshi and other effects, is the ages of food.
Maltose production period
Prebiotics and probiotics in food industry in recent years, is actually a maltose Isomaltooligosaccharides
With this, a lot of food nutrients such as vitamin V9, Yake candy
Mengniu milk, probiotic, Yeyuanfang
Plus, excellent malt sub yuan children nutrition probiotic tablets and so on, and take the concept was not a small success in the market.
Malt dust Production method
The production of maltose is divided into the following steps: firstly, wheat germination after soaking allowed up to three or four cm long, the bud chopped. Wash the glutinous rice and then poured into the pot and cook with chopped malt stir and let it ferment for 3~4 hours, until the conversion of the sap. Then filter out the juice into a paste with the fire suffering, after cooling into amber
Like candy. Edible when it is heated, and then two sticks to stir up, such as Hand-Pulled Noodle
Like the candy you can pull to the silver white.
A, maltose in the domestic workshop can be produced, main manufacturing method:
1 materials. Choose dry, clean, free of impurities (wheat or barley), corn (or rice), and non rotten sweet potato as raw material deterioration. Ratio of wheat and other raw materials for 1:10, namely 1 kg of wheat (or barley), with 10 kilograms of corn (or rice) and sweet potato etc.. The corn to be crushed into the size of millet, sweet potato dregs to be crushed into shape, but not crushed into powder.
2 bud. The wheat wheat or barley grain washed into the barrel or Wagang, soaked in water. Soak water, cooling water for summer and winter with warm water. The fruit is soaked for 24 hours after the fish into the baskets, with warm water shower shoots two or three times a day, the water temperature should not exceed 30 DEG C. After 3 days, 4 days, two to grow grain leaf wrapped heart, cut it into pieces, and more broken is better.
3 cooking. The broken corn or rice washed, soaked in water for 4 hours and 6 hours, until after the water swelling, picked up the drain, a rice cooker or
The steamer, with 100 broken corn or rice steamed to C without hard core, remove the spreading in bamboo, cooled to 40 C and 50 C.
4 fermentation. Will cool the broken corn or rice, mix chopped malt or barley malt fermentation, 5 hours, 6 hours, and then into the bag, the bag fastened.
Press 5. The bag is placed in a press or homemade juicer, squeeze juice, which is maltose.
6 concentrated. Fried juice after heating boiled, can be condensed into a certain concentration, when the moisture content is less than 18% can be kept in a cool dry place for 1 years. The water is less than 15% can be kept in a cool dry place for some time.
Two, in nature, mainly maltose in the germinated grains, especially barley malt, it was this name. In the role of starch converting enzyme, starch hydrolysis reaction, formation of maltose is it the hydrolysis reaction, generating two sub glucose.

Malt dust Nutritional knowledge
Maltose Knowledge Description: maltose is a carbohydrate food rice, barley, millet or corn and other food made from fermented. Sweet little, can increase the varieties of color and flavor dishes throughout the country are produced. There are two kinds of hard and soft, soft yellowish brown thick liquid, sticky glue, jelly; hard candy by mixing those lines, mixed air solidified, porous yellow white sugar cakes, known as white cerealose. In order to better glue medicinal jelly. Maltose is a double sugar, white crystal, soluble in water. Sweet but not sucrose, spleen, cough, the food is all ages.
Maltose nutritional analysis: maltose lungs, Sheng Jin, to dry; can be used to treat deficiency fatigue, cold abdominal pain, lung deficiency, asthma symptoms such as cough for a long time.
Supplementary information: maltose maltose (Malt sugar) is a gramineous plant barley (Hordeum vulgare L.) germination, amylase starch storage of decomposition of the disaccharide. Is the main raw material of sweet food.
The market sells maltose, alias "caramel". Not only is a mixture of maltose, glucose and maltose, including, dextrin (Dextrin).
Malt sugar for the crowd: the general population can eat, eat in patients with diabetes mellitus.
Therapeutic effect: maltose malt sugar sweet, tepid,
Has the effect of strengthening the spleen and stomach, lungs and cough,
Can be used to treat deficiency fatigue, cold abdominal pain, lung deficiency, asthma symptoms such as cough for a long time.
Maltose practice guidance: preparation of maltose:
1 the starch is heated into a paste with water, cold to 60 degrees;
2 plus malt (containing glycosylated alcohol factor), to maintain this temperature for about 1 hours;
3 boil into reheat.
Malt dust The relevant customs
Shandong Yimeng area small people: twenty-three days after the customs Small
That is almost new year's dress rehearsal". That evening the family kitchen king, from dusk firecrackers rang, with guns to King kitchen paper like incineration, which is called the king of heaven ceremony. Maltose is rectangular or melon shaped block size. Stick with the legend Kitchen God
The mouth, he went to heaven will not report to the jade family in bad. Now more you enjoy.
Malt sugar as a snack,
It's golden luster, soft and smooth, rich clay is the cause of its popularity. Maltose in ancient times known as "Yee. Analytical Dictionary of Characters
"Yi:" Bo meters also fried".
Maltose is two sugar, white crystal, soluble in water, rather than gold Qiemo
Sugar sweet than sucrose crystallization, weak. A reducing sugar, and yeast fermentation into alcohol
, dilute sulfuric acid and heat, into glucose, are often used as medicine. Ingredients
iron Production method
Only the cane juice heated into the gel, then add malt and Rice noodles cook for one hour is, but in the process it is easy to stir will not stick to the bottom. Food law
Maltose burger malt confection method diversification, basically as long as want to have this food:
Net food, food is also one of the most. such as Candy
Can squeeze into the needle cylinder, diet is quite interesting.
Production of maltose burger, net food is another popular food, often street snacks, preparation for:
To use chopsticks rolled up amount of maltose,
With two pieces of clip edible soda cake.
As food ingredients, such as desserts.
Add coconut food, and maltose clip cake.
BBQ, like honey use.
Add meat food production. Medical value
With the edible value of maltose, also has its therapeutic efficacy, it is warm and sweet, water dissolved into glucose, as a medical camp
Can be used as nourishment, beauty, spleen qi, lungs and cough, relieving pain, nourishing viscera, Chufan, constipation and other appetizers, the spleen and stomach weakness, shortness of breath, loss of appetite, cold abdominal pain, Lung dryness cough
Cough less sputum, sore throat. But in the weak, digestive capacity, body heat, body fat and sick is to be used with caution, because maltose will help wet heat, it is easy to abdominal distension. Maltose anecdote Syringes maltose
In 2005, China circulation a syringes maltose, needle filled with maltose syrup, just a squeeze, it is shot out of syrup. Because the price is cheap (each about 1.8 yuan -3.0 yuan), coupled with new and interesting, popular pupils favored. But the extension of a problem with "needle source", some people doubt the needle is medical waste, now most of them have disappeared. With easy sugar
The children spend less, eat maltose, they take the plastic toys to sell sugar exchange to eat this, easy sugar also appeared in the world to take a variety of useful waste, with business people exchange, traders will sell goods after finishing in order to make profits. This is the unique way of sale of maltose!
Malt dust Isomaltooligosaccharides
As everyone knows, maltose is two glucose molecules to alpha -1, connect the 4 glucosidic disaccharides, Isomaltose
(Isomaltose) is the two glucose molecules to alpha -1, connect the 6 glucosidic disaccharides. The molecular conformation is different, so different from the maltose and isomaltose called. Usually, maltose easily by yeast fermentation, isomaltose was yeast fermentation, isomaltose oligosaccharide is non fermented. Isomaltooligosaccharide can effectively promote the body of beneficial bacteria Bifidobacterium growth and reproduction, it is also known as the "bifidus factor", referred to as "bifidusfactor". After years of clinical and practical application showed that Bifidobacterium has many health functions, as Bifidobacterium promoting factor of Isomaltooligosaccharide naturally attracted people's attention. The nature of low poly isomaltose to very little The free state
There, but as Amylopectin
Or polysaccharide component in some fermented foods such as soy sauce, Yellow Wine or enzymatic glucose syrup in small amounts. Maltose industry using starch as an enzyme needed for the production of Isomaltooligosaccharide as raw material, the enzyme Alpha glucosidase
Aka. Glucose medium Transferase
, referred to as alpha glucosidase. It can cut the maltose and malt oligosaccharide in the molecular structure of -1 alpha, 6 glycosidic bond, which can be dissociated from a glucose residue transfer to another molecule of glucose or maltose or malt Three sugar
Other molecules in the alpha -1, 6, the formation of maltose and isomaltose three sugar, ISO Four malt sugar
Etc.. Isomaltooligosaccharides vibration sieve, sieve properties of Isomaltooligosaccharides oligo isomaltose powder machine is introduced as follows:
The white granulated sugar sweetness is 100, the following Isomaltooligosaccharides with sugar sweetness contrast (20 DEG C, and 10% sucrose solution): kinds of sugar sugar 100 high sweetness fructose
Pulp 165 glucose 70 maltose 40 sorbitol
65 Isomaltooligosaccharide syrup 1MO-50052 Isomaltooligosaccharide syrup 1MO-90042 Hight Maltose
ISO 40 oligo maltose syrup (powder) taste good, can be used to replace part of sugar, improve food flavor, reduce the sweetness.
Isomaltooligosaccharide syrup with the same concentration of sucrose solution viscosity is very close to food processing than maltose is easy to operate, no adverse effects for candy, cakes and other food structure and characteristics.
Three Heat resistance
Acid resistance, Isomaltooligosaccharide heat resistance, acid resistance is excellent. The concentration of 50% syrup decomposition long time heating is not under 120 DEG C, PH3. Applied to beverages, canned food and high temperature or low PH foods can keep the original characteristics and functions.
4 and prevent moisture The aging of starch
Isomaltooligosaccharides with moisture, the moisture evaporates, maintain moisture and quality for all kinds of food has better effect, and can inhibit the formation of crystallization of sucrose and glucose. Bread, dessert with starch as the main food, often a little store shall harden, while adding Isomaltooligosaccharide can prevent the starch aging, prolong the retention time of food.
5 color of Isomaltooligosaccharide sugar molecules for reduction of gene and protein or Amino acid
Total heat will occur Maillard reaction and produce varying shades of brown coloring, coloring degree is related with the concentration of sugar, and variety, and total heat protein or amino acid PH, heating temperature and time. So, by Isomaltooligosaccharide processing of various foods should be taken into account with the above factors.
Six Water activity
Isomaltooligosaccharides water activity: in the concentration of 75%, 25 C 0.75. Close to sucrose, for conversion to replace part of sugar cane in food in the formula is quite convenient.
Seven freezing point
Lower the freezing point of Isomaltooligosaccharide and sucrose decreased close to freezing temperature is higher than that of fructose. For cold drinks, make the product soft and delicious. 8, the fermentation of Isomaltooligosaccharide and yeast Lactobacillus
Cannot use the sugar. Added to bread, fermented milk (yogurt), yeast, lactic acid bacteria will not be lost and its characteristics using residues in food, promote the growth of bifidobacterium. Especially the normal lactic acid bacteria in fermented milk does not interfere with the fermentation.
9 anti dental caries
Of Isomaltooligosaccharides anti caries sex is good, not easy to be Tooth decay
Pathogenic variation Streptococcus
(Streptococcusmutant) fermentation, so acid produced less teeth is not easily corroded, and it can also use sucrose and sucrose, blocking is not easy to be caused by the interaction of Streptococcus mutans water insoluble High polymer
Dextran, decay inhibition of sucrose. Isomaltooligosaccharide Panose
(Panose) were formed to hinder the effect is extremely obvious. Dental caries is China's most common diseases of children, protect children's oral hygiene, prevention of dental diseases, with Isomaltooligosaccharide instead of sugar production, not easy to dental caries in the food and beverage is a very valuable work, hope to cause attention health, health food industry.
10 safety Isomaltooligosaccharides maximum no Action
The weight above 2g/kg. For Isomaltooligosaccharide Powdered sugar
The mouse, oral administration and the acute toxicity of LD50 4g/kg weight above, and low toxicity of sucrose (LD50 29.8/kg weight) and maltose (LD50 26.7/kg weight) are compared, it is extremely safe. Add the sugar in drinking water, 1 years free mice intake, daily intake for isomaltose 2.7-5.0g/kg weight, after long-term feeding test, blood test and autopsy results without any abnormal phenomenon, with abnormal chromosome variation test and regression test of bacterial cells, without any variation of the original. So, Isomaltooligosaccharides are sweeteners high security.
