STOCKHOLM, SWEDEN — Perten’s Rapid Visco Analyzer (RVA) method for determining the gelatinization temperature for milled rice flour has been approved by AACCI.
Gelatinization temperature (GT) is commonly measured to assess rice cooking and processing potential. A faster method using a small quantity of sample has been desired for some time as traditional methods of estimating rice GT using the amylograph and differential scanning calorimetry (DSC) are time-consuming and, in the case of the amylograph, require large quantities of samples — not well suited to rice breeding requirements.
The RVA is a cooking, stirring viscometer with ramped temperature and variable shear capability. It is commonly used in laboratories to measure the pasting properties of rice and provides the advantages of speed, ease of use, and small sample size requirements. In parallel testing with the traditional methods, the new RVA method also provided more precise results.
In 2022-23, the International Grains Council’s July report anticipates worldwide wheat production to reach 770 million tonnes, down from 781 million tonnes in 2021-22, with 195 million tonnes available for trade.
Most wheat production comes from a handful of countries and even fewer are major exporters, according to the Food and Agriculture Organization (FAO) of the United Nations. Here’s a look at the top 10 wheat-producing countries worldwide, based on total yield in tonnes from 2000-2020 with 2022-23 production and consumption projections.
