Product Details

Rapid Visco Analyzer Rapid-20, RVA high sensitivity and accuracy, isthe choice for detecting low viscosity samples.It can be widely usedfor the determination of gelatinization characteristics,gelatinization analyzer, amylase activity determination,saccharification power determination, germination damage,gelatinization degree analysis of modified starch and otherindicators.Fast viscometer can be used in low viscosity samples suchas starch, non-starch (colloid, protein), sauce food test, highviscosity samples such as puffed food, candy, chocolate, deformedcrosslinked starch and other fields researchShanghai SAN bao quickly viscometer RVA Rapid - 20, for the domesticRapid viscometer, and Brabender blah bend viscometer, Perten wavefast RVA viscosity instrument 4500, landing numerical tester,Australia, Newport, Rapid viscosity of RVA testing RVA profile hasgood comparability, And RVA sample consumption is small, therequirements of the operating environmental conditions are simple,very suitable for the change of material viscosity related research,especially the gelatinization characteristics of grain,gelatinization degree analyzer, amylase activity measurement,saccharification force measurement instrument.Current Rapid viscometer RVA Rapid - 20 analysis method has been theinternational grains council (ICC), the American society ofagricultural chemical (AACC), Australia (RACI) chemical researchinstitute and the People's Republic of China food association (CNAGS)accepted as standard analysis method, It is an effective analyticaltool used to analyze and test the gelatinization characteristics ofgrains, grain processing products and starch.

What is RVA?

RVA is short for Rapid Visco Analyser.It is an instrument used totest the viscosity of a sample and its change.Reasonable designallows it to quickly heat or cool the sample or keep the sampletemperature constant, so as to facilitate the user to choose the testconditions according to the purpose of the test.RVA is an effectiveanalytical tool used to analyze and test the gelatinizationcharacteristics of grains, grain processed products and starch.Inmany countries around the world, more and more scientists have usedRVA to study the process quality characteristics of food rawmaterials and the effects of various additives and processingprocesses on the quality of food products or other processedproducts.

Structural characteristics

Rapid viscometer RVA Rapid-20 application field

1. Rapid viscometer RVA Rapid-20 is used in the field of grain

breeding and cultivation

The RVA is used to measure the quality of wheat flour, similar to themethod used in the Brabender viscometer.By measuring gelatinizationcharacteristics of wheat flour with RVA, the correlation betweenifferent flour and the change of edible quality of steamed bread,bread and noodles can be studied.The use of rapid viscometer can alsoprovide a quick and simple screening method for wheat breeding.

1) The Rapid viscometer RVA Rapid-20 has been applied to the researchof wheat and rice hybridization and breeding

2) The Rapid viscometer RVA Rapid-20 is applied to the research ofgrain germination damage and climate damage

3) The Rapid viscometer RVA Rapid-20 is applied to the storageresearch of barley, wheat and rice

4) Effects of Rapid viscometer RVA Rapid-20 applied to growth typeand nitrogen application level on starch RVA spectrum characteristicsof japonica rice;

5) Effects of RVA Rapid-20 on starch RVA spectrum characteristics ofjaponica rice with different ecological types when applied to sowingdate and location;

6) Study on the variation of starch characteristics and itsrelationship with noodle quality of wheat cultivars with RVA Rapid-20;

7) The Rapid viscometer RVA Rapid-20 was applied to study thesynthesis dynamics of sucrose and grain starch in flag leaves ofwinter wheat and the related enzyme activities;

8) Rapid viscometer RVA Rapid-20 is applied to rice qualityevaluation, using the rapid viscometer can analyze the degree ofmaturation of pre-cooked rice.Gelatinization analysis program showsthat when the degree of gelation is changed to make the rice reachthe best state, there is still a considerable amount of ungelatinizedsubstance.Age also affects the texture of the rice, with fresh ricebeing stickier and aging making it dry, hard and loose. These changescan be monitored using RVA, which can reflect the effect of aging bypeak viscosity and recovery value.

9) The Rapid viscometer RVA Rapid-20 was applied to determine thecontent of damaged starch in wheat flour (α-amylase method GB/T9826-2008). The damaged starch in wheat was caused by mechanicaldamage in the grinding process.Damaged starch analyzer/damaged starchtester and RVA rapid viscometer can detect wheat flour quality,germination power, germination rate, germination potential and otherseeds are not the same.

10) Study on the interaction between protein and starch in the agingprocess of indica rice characterized by rapid viscosity analyzer.
