A ban, a split verdict, and a health concern
Rapeseed-mustard oil (hereafter 'mustard oil') is the third-largest edible oil consumed in India. Two executive and judicial decisions on mustard oil — one from 2021 and another from 2024 — have major public health implications, but have hardly received the public attention and scrutiny they deserve. In the first decision, the Food Safety and Standards Authority of India (FSSAI) prohibited the manufacturing and sale of blended mustard oil in India, effective from June 8, 2021. As per Indian food safety laws, selling an edible oil mixed with another edible oil is permitted, provided the proportion of an oil blended with another oil is within 20%. Reports suggest that FSSAI's ban decision was aimed at preventing the adulteration of mustard oil and boosting domestic mustard crop output. In the second, the Supreme Court ruled on July 23, 2024, against approval granted by the Central government for the environmental release of India's indigenously developed genetically modified (GM) mustard named Dhara Mustard Hybrid-11 (DMH-11). A major ground on which one of the two judges pronounced a judgment against DMH-11 was the insufficient assessment of the impact on human health of DMH-11. A common policy goal behind these two decisions was to protect the health of Indian mustard oil consumers. However, a closer look at the facts shows that this goal cannot be fully achieved through these two decisions. Erucic acid The mustard oil extracted from the Indian mustard crop contains high levels of a unique fatty acid called erucic acid (40% to 54% of total fatty acid). This is significantly higher than the internationally accepted level of <5%. Mustard oil containing high erucic acid is considered undesirable for human consumption, particularly in advanced countries such as the U.S., Canada, and Europe. Lab experiments demonstrated that animals fed with high erucic acid-containing mustard oil suffered from heart diseases, retarded growth, premature tissue death, and adverse changes to the liver, kidney, skeletal muscle, and adrenal glands. Though there is no conclusive evidence of a similar health impacts on humans, the stigma of the high erucic acid in mustard oil prevails in advanced economies. In those countries, the erucic acid content of mustard oil is strictly controlled by using canola oil for culinary purposes. Canola crop (oil), developed by Canada, contains less than 2% erucic acid content. Edible oil blending Due to unfavourable climatic conditions, India has not succeeded in developing a high-yielding canola-quality mustard crop. Hence, the easiest way to reduce the high erucic acid content in mustard oil is to blend it with other edible oils. Several scientific studies have proved the lower presence of erucic acid in blended mustard oil. Also, since blended mustard oil is rich in unsaturated fatty acid, consuming it lowers LDL cholesterol and increases HDL cholesterol. One primary concern with edible oil blending is adulteration with artificial flavours and poisonous substances. A nationwide survey by FSSAI in August 2020 found that 24.21% of the 4,461 edible oil samples collected did not meet the quality parameters criteria. A maximum number of adulteration and contamination was found in mustard oil. Instead of a ban, the sale of blended mustard oil can be allowed but in packaged/branded form with an explicit declaration regarding the oils that have been blended. The share of branded edible oil consumed in India is less than 30%. Strict implementation of the food safety and standards laws and strengthening of food safety infrastructure are also essential in preventing adulteration. Since health is a State subject, the food safety administration at the State level has to play a vital role in this regard. As per industry sources, the proportion of other oils blended with mustard oil in India ranges from 5% to 50%. Though this does not conform with the law, which allows blending up to 20%, it has the unintended positive consequence of reducing the erucic acid content. Hence, the sale of blended mustard oil should not be banned entirely. GM mustard Alternatively, the erucic acid content in Indian mustard oil can be reduced by cultivating the indigenous GM mustard crop DMH-11, which, apart from higher yield, has a lower erucic acid content (30-35%) compared to the traditional Indian mustard crops (40-54%). As a result, the oil extracted from DMH–11 requires a lower quantity of other edible oils for blending to reduce erucic acid content. This, in turn, helps to reduce the imports of other edible oils. India is the world's largest importer of edible oils. Its edible oil import bill is pegged at $20.56 billion by NITI Aayog. Therefore, the erucic acid-reducing property of DMH–11 and the associated health and economic benefits (in terms of reduced edible oil imports) need to be factored in by all the stakeholders while deciding on the approval of the GM mustard crop. The development of the indigenous DMH-11 with a lower erucic acid content is by no means a notable achievement by Indian genetic scientists. After years of research, Canada and Europe have successfully introduced low-erucic acid traits into their rapeseed cultivars. Hence, plant breeding programmes aimed at reducing the erucic acid content in the mustard crop to an internationally accepted level of <5% should be given top priority in India's indigenous GM mustard crop development programmes.

Nano-sulphur can boost India's mustard yields by 20-30%: TERI scientist
Field research by TERI shows nano-sulphur can push mustard yield by 25-30 per cent similar to genetically modified DMH-11 trials but by using conventional varieties Sanjeeb Mukherjee New Delhi Listen to This Article Can extensive use of nano-sulphur address India's persistent problem of low oilseeds yields—a major barrier to self-sufficiency? Scientists at The Energy and Resources Institute (TERI) believe so. Sulphur is one of the essential soil nutrients, after nitrogen, phosphorus, and potassium. TERI scientists claim that a key difference between their nano-sulphur formulation and other nano products such as nano urea and nano diammonium phosphate (DAP) is that their product is completely green, developed using biological agents like plant growth-promoting bacteria that release enzymes and metabolites. These enzymes and metabolites facilitate the conversion of bulk material into nanoparticles.
