The Basmati rice name is like Champaign, geography exclusive. Basmati rice can grow in specific districts of India and Pakistan. The prices of Basmati rice are about 3X higher than long grain. It creates a good motivation to blend (mix) lower-cost varieties or lower grades rice to maximize seller profit. Food companies are at the end of the supply chain starting from the farmer, trader, processing, packing, and logistics companies may be exposed to a higher financial and regulatory risk. Food companies produce the final product, closer to the consumer demanding taste and consistency, and exposed to FDA regulations. The current manual inspection to identify non-Basmati rice is not sufficient. According to the government of India, a precooked milled Basmati rice length must be at least 6.61 mm and width of 2mm. One method is to handpick 10-20 kernels from a sample and measure the length and width of each kernel with the caliper and calculate the average values, the other method is to put 15 kernels in a row, measure the total length, and dived by 15 to calculate the average length. Same with the width measurement. A sample of 20 g has about 1,200 kernels so practically and statistically these outdated methods cannot provide accurate information and indication on blending level and use the results as evidence and for communication with the seller normally based overseas.
