Basmati Rice - which ones are less adulterated
12 brands of rice DNA tested
Quality score of each brand based on lab tests
The highest overall test scores went for Golden Harvest and Lal Qila (92/100 each). It was followed by Patanjali (89/100), Tilda (88/100) and Asbah and India Gate ( 87/100 each). The lowest rankings were for Fortune (62/100) and Kohinoor (63/100). Rest of the brands were rated in between: Daawat (84/100), Organic Tattva (82/100), Aeroplane (81/100) and Heritage (76/100).
While Golden Harvest (Rs 130/kg) and Lal Qilla (Rs 150/kg) were adjudged as top quality, Patanjali was adjudged as best value for money being pieced at Rs 125 per kg.
DNA Tests
DNA testing is mainly used to determine if parent is biologically related to the child. Similarly DNA (deoxyribonucleic acid) test was conducted to determine purity of basmati rice. The test can detect adulteration of non-basmati rice. Presence of inferior varieties of rice is considered as adulteration. The admixture of common rice in basmati rice should not exceed limits prescribed in Agmark. This criteria had a weightage of 25/100 in Consumer Voice ranking. Only Golden Harvest and Lal Qilla scored full marks (25/25) as pure basmati as they had no trace of any other variety. All other brands were contaminated with a share of non basmati rice varying from a low of 2.8 per cent (Patanjali ) to a high of 36.6 per cent (Kohinoor).
Physiochemical , sensory and safety tests conducted
Sixteen different tests were conducted to measure different physiochemical characteristics including quality of grains, energy and nutrition content, uric acid and aflatoxins among others. Safety tests included test for lead and arsenic as well as 37 pesticides. All the brands were within safe limits. ‘Organic Tattva’ contained pretilachlor pesticide which demolished its claim of being organic.
Sensory tests were conducted by an expert panel. Rice was boiled and experts assigned scores out of 12 based on fragrance/ aroma, appearance, size of kernel, colour, texture and taste. Tilda got highest score of 10.49/12 while Heritage got the lowest of 7.8/12. Brands were also scored for packing, marking and net weight.
Consumer Voice tested 12 leading brands of basmati rice on the above-mentioned parameters as well as other key quality determinants. A crucial aspect of the test was DNA analysis of the samples to detect adulteration with non-basmati rice. Other key parameters included grain length/ breadth ratio, average precooked grain length and elongation ratio. Samples were also checked for presence of broken or fragmented grains, damaged/discoloured grains, chalky grains, green grains, other grains, moisture, uric acid, aflatoxins and foreign matter (such as dust and stones). A major health-related parameter was presence of heavy metals (lead and arsenic) as well as pesticide residues. more

Most brands have multiple varieties within the category of basmati rice, with different rates. It will be useful to know which variety of each brand was tested. more

Good analysis. But public is interested to know which variety of Basmati Rice is not fit for consumption due to adulteration. Which all can lead to slow & steady germination of disease and thus shorten the life span of consumers. more

Thanks for the good effort. Another issue would be that duplicate packs under the top brand. How do we check that? more
