Background: Even though iodine is not an essential micronutrient for the plant, it is very much needed for a person&#39;s mental and physical development. Due to the presence of negative charge on iodine it is highly susceptible to leaching. Further iodine is also highly prone to volatilization loss due to biochemical and physiochemical properties of soil leading to iodine deficiency. Agronomic biofortification of iodine is one of the ways to address iodine deficiency globally. Numerous studies have focused on the process by which plants absorb iodine from the soil, but there is still paucity of knowledge on stability of biofortified iodine in fruits.

Methods: In our work, we assessed iodine bioavailability (Cooking, soaking and digestion) in tomato fruit from different sources of chitosan and potassium iodate alone and combinations using main and residual crop trials. The field experiment was carried out in Thondamuthur block of Viraliyur village at Coimbatore district of Tamil Nadu in 2021. Potassium iodate and chitosan were applied in the form of soil, foliar, and chitosan iodate complex at different stages of plant growth. &nbsp;

Results: The results suggested that combination and potassium iodate and chitosan complex has increased the iodine stability in fruits of main crop and also retained the iodine in residual crop. As electrostatic interaction between chitosan and iodate prevents volatilization and gradually stabilizes the bioavailability of iodine in fruits. Our findings offer more details on iodine mobility and behaviour in fruits when it is used alone and combination with chitosan at different rates.

Background: Finger millet (Eleusine coracana) is recognized for its high nutritional value and potential as a staple food source across various regions. However, its widespread adoption is limited due to the presence of antinutritional factors which inhibits nutrient absorption.&nbsp; This study investigates the effect of sonication as an innovative processing technique on the finger millet malt&rsquo;s nutritional profile, antioxidant components and micronutrient bioaccessibility.&nbsp; 
&nbsp; 
Methods: During the hydration process, finger millet grains were subjected to different sonication treatments and optimized with the help of central composite design in design expert software. Parameters like Angle of Repose, water activity, water holding capacity, moisture content, color, calcium, iron and % of bioaccessibility of calcium and iron were analyzed using standard protocols. 
&nbsp; 
Result: Sonication treatment significantly improved the physical, nutritional and functional properties of finger millet malt. The angle of repose increased from 27.45&plusmn;0.95 to 35.52&plusmn;0.82, while water activity, water holding capacity (%) and moisture content (%) enhanced from 0.544&plusmn;0.00 to 0.596&plusmn;0.00, 201.36&plusmn;0.95 to 218.36&plusmn;1.96 and 7.27&plusmn;0.56 to 7.88&plusmn;0.48, respectively. Nutrient content showed remarkable enhancement, like calcium (mg/100 g) and iron (mg/100 g) from 323&plusmn;0.13 to 341&plusmn;0.45 and 3.73&plusmn;0.54 to 7.12&plusmn;0.22. Concurrently, antinutritional factors such as phenols (mg/100 g) and tannins (mg/100 g) decreased from 126.22 to 50.11 and 107.91 to 50.64, respectively, boosting mineral bioaccessibility. Calcium and iron bioaccessibility (%) improved from 0.51 to 36.54 and 1.92 to 58.26. Optimal conditions were observed at 18 min, 30&deg;C and 100% amplitude, making finger millet malt a superior and palatable food ingredient.
