sucrose is the most common food and sugar, also used in citric acid, caramel, invert sugar, transparent soap. Sucrose can inhibit the growth of bacteria at high concentration, and can be used as a tablet excipient for preservatives and antioxidants. In 1980, the world production of raw sugar was 87.1 million t, including 52 million t of sucrose and 35 million t of beet sugar. Sucrose from sugar cane and sugar beet is limited by the natural conditions of slow development, the world's sugar deficiency is more serious. In addition, various special needs have promoted the research and development of new sweeteners, and many natural sweeteners and synthetic sweeteners have been found. Reagent sucrose is used for the determination of 1-naphthol, and also for the separation of calcium and magnesium and the preparation of biological medium.
can be widely used in food, cosmetics, medicine, but also for analytical testing of standards.
used as standard for organic elemental analysis
reagent sucrose is used for the determination of 1-naphthol, and also for the separation of calcium and magnesium and the preparation of biological medium. Cell culture grade was used for sucrose gradient purification of Virus and protein. Plant cell culture grade is used for cryoprotection in plant cells. Molecular biology grade isobaric Centrifugation Methods for discontinuous sucrose density gradients, such as: isolation of mRNA from membrane bound ribosomes.
Multi-substance preservation solution and auxiliary solution
biological medium. Separation of calcium and magnesium. Determination of 1-naphthol. Masking agent for Complexometric titration of boron. Standards for the determination of carbon, hydrogen and oxygen by organic microanalysis.
production method sucrose comes in large amounts from cane sugar and sugar beet, sugar cane contains about 15-20% sucrose and sugar beet 10-17%. Various other fruits, seeds, leaves, flowers, roots also have different content. The sugar cane is squeezed out or the sugar beet slices are extracted with water, and the lime clarification method or the sulfurous acid saturation method is used to remove the impurities in the sugar juice. After filtration, the filtrate is concentrated in vacuum, recrystallization and separation of crude sugar, and then by decolorization, recrystallization and refined sugar.
obtained by clarification, evaporation and crystallization of sugar cane or sugar beet after pressing or Diafiltration.
