Sucrose chemical formula: C?H?O?

Sucrose to ethanol undergoes the following process:

1, the decomposition of sucrose, to obtain glucose and fructose;

2, glucose decomposition in cytoplasmic matrix and pyruvic acid;

3, it must be in the cytoplasmic matrix of plant cells in order to pyruvic acid to ethanol, and the release of carbon dioxide.

Sucrose is a disaccharide (glucose + fructose), white crystals, with spin, but no variable spin. Easily hydrolyzed by acid, hydrolysis produces equal amounts of D-glucose and D-fructose. It is not reducing. Caramel formed by fermentation can be used as a color enhancer for soy sauce.

Sucrose is the main product of photosynthesis, widely distributed in the plant body, especially sugar beet, sugar cane and fruit in the content is very high. Sucrose is the main form of sugar storage, accumulation and transportation in plants.

The raw materials for sucrose are mainly sugar cane (Saccharum?spp.) and sugar beet (Beta vulgaris). The sugar cane or sugar beet is crushed with a machine, the sugar juice is collected, filtered and treated with lime to remove impurities, and then bleached with sulfur dioxide; the treated sugar juice is boiled, the sunken impurities are pumped away, and the foam that floats to the surface is scraped away, and then the fire is extinguished to wait for the sugar syrup to crystallize into sucrose.

History

Sugar production began in Lingnan in the first century or so. In the early Eastern Han Dynasty, Yang Fu, a native of Guangdong, wrote the "Record of Foreign Objects", which recorded that sugar cane juice was made into "syrupy molasses", which was then crystallized into a solid cane sugar called "stone honey".

The Tang Dynasty sugar and sugar cane began to spread to the north. Tang Dynasty monks often use sugar in medicine, and sugar water bath, to China's Arab and Persian merchants also a large number of sugar flavoring. However, sugar was still not commonly used by the general public. The New Book of Tang records that Emperor Tang Taizong sent an envoy to Magadha (India) to get the method of boiling sugar, indicating that Indian sugar refining was introduced to China during the Tang Dynasty.

In the early Northern Song Dynasty, the three Buddha Qi and the Great Food and other countries tributes to white sugar. Song Dynasty appeared the world's first sugarcane sugar refining monograph "Sugar Cream Spectrum". Sugar production in the Song Dynasty became an important industry, a wide range of sugar products, there are fragrant candy, lion sugar, flower sugar, gum teeth sugar, sesame sugar, hammer sugar, prune sugar and so on.

Italian traveler Marco Polo's "Travels" recounts the sugar industry in Wugan, China, began to do not know how to refine like the sugar produced in the Babylonian region as exquisite, and then the Great Khan got from the Babylonian region of the people taught to use tree ash refined sugar technology.

Ming Song Yingxing's "Tiangongkaiwu," Volume VI, "Ganxiao," a detailed account of the method of making white sugar and rock sugar.
