1、 Starch gelatinization analyzer RVA , Product introduction
Introduction to fast viscosity analyzer
Rapid visco analyzer;, RVA has high sensitivity and accuracy, which is the choice for detecting low viscosity samples
It can be widely used to determine the gelatinization characteristics of grain, gelatinization degree analyzer, activity measurement, saccharifying power measurement, germination damage, gelatinization degree analysis of modified starch and other indicators
Starch gelatinization analyzer can be applied to the testing of low viscosity samples such as starch, non starch (colloid, protein) and soy sauce food, and the research of high viscosity samples such as expanded food, candy, chocolate, deformed cross-linked starch and so on

Shanghai Baosheng starch gelatinization analyzer RVA , ， It is a domestic starch gelatinization analyzer, Brabender Brabender viscometer, perten botton starch gelatinization analyzer RVA 4500
Landing value tester, Newport Australia; The RVA spectra of starch gelatinization analyzer are well comparable, and the amount of RVA sample is small and the requirements for operating environmental conditions are simple
It is very suitable for the research related to the change of material viscosity, especially the research of grain gelatinization characteristics, gelatinization analyzer, activity determination and saccharification force tester
At present, the analysis method of starch gelatinization analyzer has been accepted as the standard analysis method by the international grain Association (ICC), the American Association of Agricultural Chemistry (AACC), the Australian Institute of Chemistry (Raci) and the grain Association of the people's Republic of China (CNAGS)
It is an effective analysis tool used to analyze and test grains, grain processed products and starch gelatinization characteristics
What is RVA?
RVA is the abbreviation of rapid visco analyzer
It is an instrument used to test the viscosity and change of samples
The reasonable design makes it possible to quickly heat or cool the sample or keep the sample temperature constant, so that users can choose the test conditions according to the purpose of the test
RVA is an effective analysis tool used to analyze and test Cereals, cereal processed products and starch gelatinization characteristics
In various countries, more and more scientists have used it to study the process quality characteristics of grain raw materials and the effects of various additives and processing technologies on the quality of grain products or other processed products

2、 Starch gelatinization analyzer RVA , application area
1
Starch gelatinization analyzer RVA , It is used in grain breeding and cultivation
Using RVA to measure the mass of wheat flour is similar to the method used by Brabender viscometer
The gelatinization characteristics of wheat flour determined by RVA can study the correlation of different flour on the edible quality of steamed bread, bread and noodles
Starch gelatinization analyzer can also be used for Wheat Breeding The work provides a fast and simple screening method

1) Starch gelatinization analyzer RVA , It is applied to the research of wheat and rice hybridization and breeding
2) Starch gelatinization analyzer RVA , It is applied to the research of grain germination damage and climate damage
3) Starch gelatinization analyzer RVA , It is applied to the storage of barley, wheat and rice
4）  Starch gelatinization analyzer RVA , It was applied to the effects of growth type and nitrogen application level on Starch RVA spectrum characteristics of Japonica rice;
5) Starch gelatinization analyzer RVA , It was applied to the effects of sowing date and location on Starch RVA spectrum characteristics of different ecological types of Japonica rice;
6) Starch gelatinization analyzer RVA , It was applied to the study of starch characteristic variation of wheat varieties and its relationship with noodle quality;
7) Starch gelatinization analyzer RVA , It was used to study the synthesis dynamics of sucrose and grain starch in winter wheat flag leaves and the related enzyme activities;
8) Starch gelatinization analyzer RVA , The starch gelatinization analyzer can be used to analyze the ripening degree of precooked rice
Gelatinization analyzer The results showed that there were still quite a few when the degree of gel was changed to make the rice reach a good state   An amount of non gelatinized substance is present
Storage life also affects the texture of rice, fresh The rice is sticky, and the aging process makes the rice taste dry, hard and loose
These changes can be monitored by RVA, and the peak viscosity and retrogradation value can be used to reflect the effect of aging

9) Starch gelatinization analyzer RVA , Applied to the determination of damaged starch content in wheat flour (& alpha; - Method GB / T 9826-2008), the starch particles in wheat are mechanically damaged during grinding to produce damaged starch
Damaged starch analyzer / damaged starch analyzer and RVA starch gelatinization analyzer can detect the quality of wheat flour, the germination power, germination rate and germination potential of barley, which are different from other seeds

10) Study on the interaction between protein and starch during aging of Indica Rice by rapid viscosity analyzer
