1、 Product introduction of rapid viscometer RVA rapid-20
Introduction to fast viscosity analyzer
Rapid visco analyzer rapid-20, RVA, with high sensitivity and accuracy, 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
The rapid viscometer 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 rapid viscometer RVA rapid-20 is a domestic rapid viscometer, which is similar to Brabender Brabender viscometer, perten wave fast viscometer RVA 4500
Landing value tester, Newport Australia; The test RVA spectra of RVA rapid viscometer 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 degree analyzer, activity measurement and saccharification force measurement instrument
At present, the rapid viscometer rva-20 analysis method has been accepted as a 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、 Application field of rapid viscometer RVA rapid-20
1
Rapid viscometer RVA rapid-20 is used in the field of 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
The rapid viscometer can also provide a rapid and simple screening method for wheat breeding

1) Rapid viscometer RVA rapid-20 is applied to the research of wheat and rice hybridization and breeding
2) Rapid viscometer RVA rapid-20 is applied to the research of grain germination damage and climate damage
3) Application of rapid viscometer RVA rapid-20 in storage of barley, wheat and rice
4) Rapid viscometer RVA rapid-20 was applied to the effects of growth type and nitrogen application level on the RVA spectrum characteristics of Japonica rice starch;
5) Rapid viscometer RVA rapid-20 was used to study the effects of sowing date and location on Starch RVA spectrum characteristics of different ecological types of Japonica rice;
6) RVA rapid-20 was used to study the variation of starch characteristics of wheat varieties and its relationship with noodle quality;
7) RVA rapid-20 was used to study the synthesis dynamics of sucrose and grain starch in winter wheat flag leaves and their related enzyme activities;
8) RVA rapid-20 is used to evaluate the quality of rice
The ripening degree of precooked rice can be analyzed by using RVA rapid-20
The gelatinization analysis program showed that when the degree of gel was changed and the rice reached a good state, there were still a considerable amount of substances that were not gel
The storage life also affects the texture of rice
Fresh rice is sticky, while 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) Rapid viscometer RVA rapid-20 is applied to the determination of damaged starch content in wheat flour (& alpha; - Method GB / T 9826-2008)
Damaged starch is produced due to mechanical damage of starch particles in Wheat during grinding
Damaged starch analyzer / damaged starch tester and RVA rapid viscometer 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

Application of rapid viscometer in starch field
1) RVA rapid-20 is applied to natural starch or modified starch, and the complete gelatinization characteristic test can be completed in only 13 minutes; Rapid viscosity analyzer (RVA) in modified starch (acidic, oxidized, crosslinked, substituted starch), & alpha- Application of activity, storage life of barley and rice and prediction of food quality such as noodles, steamed bread and bread;
2) RVA rapid-20 is used in the manufacture of high viscosity substituted and crosslinked food starch, deformed starch and modified starch;
3) Rapid viscometer RVA rapid-20 was applied to study the relationship between Starch RVA spectrum characteristics and edible quality of Japonica rice;
4) Rapid viscometer RVA rapid-20 was applied to the relationship between Starch RVA spectrum characteristics and eating quality of Two-line Japonica Hybrid Rice in North China;
5) Rapid viscometer RVA rapid-20 was used to study the resource quality characters of Japonica Rice with low amylose content and low protein content;
6) Rapid viscometer RVA rapid-20 was applied to rapid identification of starch viscosity characteristics of early indica rice with different apparent amylose content by RVA spectrum;
7)  Rapid viscometer RVA rapid-20 is used for & alpha- Evaluation of enzymatic hydrolysis effect;
8) Rapid viscometer RVA rapid-20 was used to detect the adulteration of five kinds of edible starch;

10) RVA rapid-20 modified starch refers to the use of physical, chemical or enzymatic treatment to introduce new functional groups into starch molecules or change the size of starch molecules and the properties of starch particles in order to improve the properties of starch and expand its application range (  e
g
  gelatinization temperature, thermal viscosity and its stability, freeze-thaw stability, gel force, film-forming property, transparency, etc
