Fortified Rice Kernels Testing

Fortified rice kernels are rice grains enriched with a mix of vitamins and minerals to address micronutrient deficiencies, particularly in populations that rely heavily on rice as a staple food. These kernels are produced through a process called extrusion, which involves blending a nutrient mixture with rice flour and shaping the blend into rice-like kernels. Once produced, the fortified kernels are mixed with regular rice at a ratio of 0.5-2%. This method is considered the most robust for rice fortification and can be applied to any rice variety. The fortified rice kernels can also be customized in terms of shape, size, and colour to create food products with broad appeal.

Micronutrients deficiencies can lead to a range of health problems, including anaemia, impaired immune function, and developmental delays in children. Fortification of rice with essential micronutrients is a cost-effective and sustainable way to improve the nutritional status of populations, and it has been endorsed by organizations such as the World Health Organization (WHO) and the United Nations International Children's Emergency Fund (UNICEF).

Types of fortified rice kernels

There are different types of fortified rice kernels available, depending on the specific micronutrients added and the intended target population. Here are some examples:

Type of Fortified Rice	Key Micronutrient(s)	Benefits
Iron-fortified rice	Iron	Healthy red blood cells and cognitive development
Zinc-fortified rice	Zinc	Immune function and growth and development
Vitamin A-fortified rice	Vitamin A	Vision, immune function, and growth and development
Multiple micronutrient-fortified rice	Iron, Zinc, Vitamins A, B1, B3, B6, B12	Comprehensive approach to addressing multiple micronutrient deficiencies

Consumer Acceptance Testing
Acceptance and Satisfaction	Conduct trials with target populations	Surveys and feedback collection from consumers regarding taste, texture, and overall satisfaction
Regulatory Compliance
Compliance	Ensure compliance with local and international food safety and fortification standards	Review and align with regulations such as Codex Alimentarius, FDA, EFSA guidelines

Market overview

The market growth can be attributed to the increasing demand for nutrient-rich foods, rising awareness about the importance of a healthy diet, and a growing prevalence of micronutrient deficiencies worldwide. New technologies to produce fortified rice products and the investments made by governments and private players in research and development as factors driving the market growth. Overall, the fortified rice market is expected to experience a CAGR of 6.3% during the forecast period 2022-2027 and reach a market size of $28.4 billion by 2027.

According to the FSSAI, a scientific panel is developing standards for fortified rice kernels (FRKs) to ensure quality and blending efficiency. Rice can be fortified using dusting, coating, or extrusion technology, with extrusion being the preferred method. The Food Fortification Resource Centre (FFRC) provides testing parameters for labs using FSSAI validated methods for testing of fortified rice. The standards that have been put in place by FSSAI for fortified rice are

S.No.	Nutrient	Level of Fortification per Kg
1	Iron (a) Ferric pyrophosphate (b) Sodium Iron (III) Ethylene diamine tetra Acetate,Trihydrate (Sodium federate-Na Fe EDTA)	20 mg
2	Folic acid	1300 µg
3	Vitamin B12 cyanocobalamine hydroxycobalamine	10 µg
