Method for detecting sugar content in sugarcane juice

Abstract

The invention discloses the measurement method for the cane sugar. Its method includes the water solution of cane sugar, the reaction of Reducing Sugar and iron cyaniding potassium, second iron cyaniding the electric potential titration of the potassium. The method of the invention has to operate easily, measurement result stability credibility, the measurement variation coefficient of result is small, the error margin is small, but it is easy to carry out instrument to turn.

Description

Technical Field: [0001] The invention relates to a method for determining the sucrose content in sugarcane juice. Background technique: [0002] Sucrose is the most commonly used sweetener in the world. It has a wide range of uses in the food industry and is the most commonly used food additive. The production of sucrose mainly uses sugar cane and sugar beet as raw materials, the north is mainly sugar beet, and the south is mainly sugar cane. The level of sucrose content in sugarcane directly affects the interests of sugar companies. The promotion of quality-based pricing will not only improve the enthusiasm of sugarcane farmers to plant high-quality sugarcane, but also improve the production efficiency of sugar companies. Therefore, the determination of sucrose content in sugarcane juice It is of great significance. [0003] At present, the main detection methods of sucrose at home and abroad are: 1. Optical rotation method: The optical rotation method is currently the most comm...

[0003] At present, the detection methods of sucrose at home and abroad mainly include: 1. Optical rotation method: Optical rotation method is the most commonly used method for detecting sucrose at present. Optical rotation method, the error of the first optical rotation method is relatively large, and the second optical rotation method eliminates part of the error, and can measure more accurate sucrose content, but the operation of the optical rotation method is cumbersome, and basic lead acetate must be added to clarify the cane juice during the measurement, which is harmful to the environment and cannot be carried out. Determination of large quantities of samples; 2 near-infrared method: the near-infrared method uses the absorption of near-infrared rays by the measured object to analyze the sucrose composition. In foreign countries, such as Australia, Italy, France, Brazil and the United States, near-infrared analyzers have been used The rapid determination method of direct determination of sucrose, because the detector used in this method is relatively expensive, and a large amount of data collection is required, it is difficult to popularize and use this method. At present, this method is rarely used in my country; The photometric method has high requirements on the background and is easily interfered by other substances, so its practical application is less
