What are the common sweets?

A disaccharide formed by the condensation of two sugar molecules through a а glycoside bond. It is the main component of maltose. Made from malt containing amylase acting on starch. Used as a nutrient and also used to prepare culture medium.

From a chemical point of view, maltose (or maltose) is a chemical term and belongs to disaccharide. It is a white needle-like crystal. However, the common maltose is not crystallized, and because sucrose is added during cooking, the white maltose turns golden yellow, which increases its color and fragrance.

Maltose is also called glutinous rice sugar.

It is made of wheat and glutinous rice, sweet and delicious, rich in nutrition, and has the effect of invigorating stomach and promoting digestion. It is a kind of food suitable for all ages.

The production of maltose is roughly divided into the following steps: first, soak wheat, let it germinate to three or four centimeters long, and take its buds and chop them for later use. Then clean the glutinous rice, pour it into the pot, stew it, stir it evenly with the broken malt, and ferment it for 3-4 hours until it becomes juice. Then the filtered juice is boiled into paste with strong fire, and amber candy is obtained after cooling. Heat it when eating, and then use all kinds of sweets.

Stir out two sticks and pull the candy as silvery as Lamian Noodles.

1. In nature, maltose mainly exists in germinated grains, especially malt, hence the name. Under the action of starch invertase, starch is hydrolyzed to maltose, and maltose is hydrolyzed to two molecules of glucose.

Maltose can be made into crystals and used as a sweetener, but the sweetness is only 1/3 of sucrose. Maltose is a cheap nutritious food, which is easily digested and absorbed by human body.

Maltose has aldehyde groups in its molecular structure, which is reducing and a reducing sugar. Therefore, it can react with silver ammonia solution through silver mirror, or it can react with newly made basic copper hydroxide to generate brick red precipitate. It can hydrolyze to produce two molecules of glucose under certain conditions.

Second,

Colorless or white crystals, thick syrup. The crystalline maltose of one molecule of water melts and decomposes at 102 ~ 103℃. Soluble in water, slightly soluble in ethanol. The reduced disaccharide reacts with aldehyde group to produce silver mirror reaction.

Should, also can use Bancroft reagent (with copper sulfate, sodium carbonate or caustic soda, sodium citrate and other solutions) * * heating to generate brick red cuprous oxide precipitate. It can make bromine water fade and be oxidized into maltogenic acid. Heating in dilute acid or α -glucose

Hydrolyzed into 2 molecules of glucose by glucosidase. Used as food, nutrition, etc. It is made by hydrolysis of starch, which is usually made by mixing enzymes in malt with starch paste and fermenting at a suitable temperature.

maple sugar

sugar

Acer, also known as sugar maple, is a tall deciduous tree. It is 40 meters high, 40- 100cm in diameter and 500 years old. The trunk contains the most starch and turns into sucrose in winter. In warm weather, sucrose will turn into sweet juice. As in a book

When drilling a hole, the sap will flow out continuously. Sugar made from boiled tree juice is called maple syrup or maple syrup. Maple sugar is rich in minerals and organic acids, and its calorie is lower than that of sucrose, fructose and corn sugar, but it contains calcium, magnesium and organic acids.

But it is much higher than other sugars, which can supplement the weak constitution with unbalanced nutrition. The sweetness of maple sugar is not as high as honey, and the sugar content is about 66% (the sugar content of honey is about 79%-8 1%, and the sugar content is as high as 99.4%).

Classification of Canadian maple syrup:

Canadian item number 1 AA color: golden color: light fragrance

The production season is in early March, and it is maple syrup condensed from the earliest harvested sap.

Because of its light taste, it is very suitable for children, the elderly and post-illness patients, especially those with heart disease and diabetes.

Canada No 1 A, color: golden brown taste: aromatic.

The production season is around the middle of March, and the maple syrup is harvested.

Friends who like the special traditional flavor of maple sugar, this grade will be your best choice. It will definitely join your dinner table and become your indispensable partner every day. Try to use it instead of sugar when drinking coffee, tea and cooking. I believe you will find that it can change your poor health and bring you unexpected results.

Canada second amber, color: light brown taste: aromatic.

Maple syrup made at the end of the harvest season in early April.

It has a strong maple fragrance, and people who like strong maple syrup believe that its unique and unforgettable taste will never live up to your choice. Dessert used for cooking cookies and cakes is an indispensable seasoning helper. Canada's famous international maple syrup and maple syrup ice cream use this grade as the protagonist.

The strong taste (Canada No.3 is deeper) is sometimes called amber grade in Canada No.3. Color: Brown Taste: Maple syrup is made at the end of April, the last harvest season of the year, with special fragrance and strong production season.

This is a special maple syrup for cooking, which is characterized by caramel-like taste. Mainly because of its strong smell, it is widely used in cooking, baking and some special food condiments. In Europe, the United States and Japan, it is also used as a spice to make a popular maple sugar-flavored cigarette.

Every year from May to August, maple trees store starch in their roots to prepare nutrients for the next year. When the snow and ice melt in early spring, the starch stored in the roots of maple trees begins to be converted into sugar, which is also the season when maple sugar workers begin to collect sap and make maple sugar. Maple sugar season is very short, generally from mid-March to mid-April, only about six weeks before and after.

maple

The production of sugar is also very simple, that is, the maple sugar is heated to evaporate the water in the sap bit by bit, and finally a slightly thick maple syrup is formed, usually

40 kg maple juice can only process 1 kg maple syrup. Only maple trees over 40 years old or more than 25 cm in diameter will produce useful juice. For the healthy growth of maple, the amount of juice taken should not exceed the total amount.

5%。 So maple sugar is very expensive.

This sugary maple is different from other maples. It is yellow in autumn, while other maples are red.

Zongzi sugar

Zongzi is one of the earliest candies in China. It is mainly made of rose, maltose and pine nuts with sucrose.

Its shape is like a triangular zongzi, hence the name zongzi sugar. Jiaozi sugar is hard, transparent and shiny. You can clearly see that roses and pine nuts are evenly scattered in the sugar, just like beautiful crystal stones. Sweet and delicious, with the fragrance of pine nuts and roses. Due to the influence of climate, it is not suitable for production in summer.

Raw material formula sucrose, pine nuts, dried roses, liquid glucose, vinegar essence.

manufacturing method

1 Cooking sugar is the same as peanut candy.

Pine nuts and roses must be roasted, otherwise they can't be used, so as to avoid the resurgence of pine nuts and roses. It is easy to turn sugar into sand by pouring sugar paste.

3. After the sugar is cooled and boiled to 160℃, pour it on a cooling table filled with tap water, sprinkle pine nuts and dried roses on the sugar paste while it is hot, and fold it back and forth with a scraper. When the sugar paste is folded and cooled, the water evaporates continuously, and the sugar paste gradually condenses into soft candy.

4 Integer: Quickly organize manpower and speed. Put the fudge on the counter, divide it into small pieces, and knead the sugar into round strips (keep the room temperature).

5 cut sugar: cut sugar with scissors. When cutting sugar, you should pay attention to turning it over every time. Cut sugar is triangular from any side, and now it is produced by machine. You can also cut out triangles.

6 packaging: the sugar is fully cooled and then packaged to avoid sticking sugar easily.

Quality standard color: light yellow brown, transparent and shiny.

Form; Triangle, no broken edges and short corners, 240 ~ 250 pieces per kilogram.

Osmanthus sugar

This kind of sugar, formerly known as "foreign sugar" in our city, is a traditional seasonal specialty in our city. In ancient times, there was a folk song "Taoyuan wine, sugar in the city, fried dough sticks in the river." Long-handled fried dough sticks are purely exaggerated, but Taoyuan famous wine and Qiao's "foreign sugar" are worthy of the name.

Shi Jiao's "foreign sugar" originated in the late Ming and early Qing Dynasties, and its predecessor was the tube sugar in Taoyuan Township.

this

That kind of sugar is for the county magistrate and Jun Fu, and it is a tribute to the palace. All products are listed as "best products" and won prizes. Since then, they have gained a great reputation and their sales scope has become wider and wider. And together with Hong Kong businessmen who buy oil and timber, they export to foreign countries. "foreign

Sugar "also got its name. Later, with the development of history, the production method and quality of "foreign sugar" continued to improve, and "foreign sugar" evolved into sweet-scented osmanthus sugar, which was twice rated as a national high-quality product.

Won the silver medal.

Sweet-scented osmanthus sugar is fried with rice soaked in oil, and sweet-scented osmanthus with white sugar as the core sugar. The firepower is appropriate, the hemp is evenly spread, and the branches are neat. Osmanthus fragrans used for making must be fresh and fragrant. When it is in full bloom, pick the flowers from the tree. Add white sugar and seal it, and it becomes the raw material of heart candy. Sweet-scented osmanthus sugar is very strict in the choice of sweet-scented osmanthus, and its production is also very elegant.

Sweet-scented osmanthus sugar is one of the specialties of Taoyuan, which enjoys a good reputation at home and abroad.

starch sugar

profit

Sugar, including maltose, glucose, fructose syrup, etc. Starch sugar is made from starch grains and potatoes by acid method, acid enzyme method or enzyme method. Starch sugar has a long history in China, which began in 500 AD.

For many years, sugar has been mentioned in Qi Yao Ming Shu, and the method of making sugar from rice has been described in detail. The production and consumption of sugar in China has long been dominated by sucrose, supplemented by starch sugar, which has been strongly supported and popularized by the state in recent years.

Starch sugar. By the end of the ninth five-year plan, due to the technological progress of starch sugar industry, the output and quality were improved and the material consumption was reduced; With the intensive and large-scale operation of enterprises, the cost of starch sugar products has decreased and the starch sugar market has gradually expanded.

Big, become an important supplement to the sugar market. Starch sugar has a wide range of consumption areas and a large consumption. It is a pillar product of starch deep processing. It has been widely used in many industries such as food, medicine and paper making for a long time. In recent years, along with

With the deep processing of corn, the development of food industry, the progress of biotechnology such as enzyme preparation and the change of people's consumption structure, China's starch sugar industry has made remarkable development, towards multi-variety, personalization, specialization and scale development.

Exhibition, the output increased substantially, and the variety structure improved day by day.

In 2005, the output of starch sugar reached 4.2 million tons and the output value reached 9.24 billion yuan. China ranks second in the world in starch sugar production after the United States. Starch sugar industry is one of the important ways of agricultural industrialization and grain deep processing. Therefore, starch sugar industry plays an important role in China's national economic development.

toffee

Toffee is a western-style candy made of brown sugar or molasses and cream. It is made by boiling molasses brown sugar until it is very thick, and then stirring the substance by hand or machine until the candy becomes shiny and can maintain a solid shape.
