Millets are widely recognized for their nutritional significance; however, the methods emp.oyed for their p.ocessing are currently lacking. This article p.imarily focuses on the advanced technologies and p.ogressions in millet dehulling and p.lishing. These technologies op.rate based on the fundamental p.incip.es of comp.ession-shearing, abrasion-friction, and centrifugal-imp.ct forces. p.ocessing of millets can be challenging because of the p.ysical characteristics and tight attachment of hull and bran to the endosp.rm. However, several dehullers have been designed to solve this p.oblem for different kinds of millets. In addition, the nutritional and anti-nutritional characteristics undergo alterations due to both dehulling and p.lishing p.ocesses. These alterations are thoroughly examined and discussed in this article. Sp.cifically, anti-nutrients such as tannins and p.ytate are p.edominantly found in the outer p.ricarp.of the grain and exp.rience a reduction after undergoing dehulling and p.lishing. The nutritional p.op.rties are also subjected to a reduction; however, this reduction can be mitigated by subjecting the grains to certain p.etreatments before dehulling and p.lishing. These treatments serve to enhance dehulling efficiency and nutrient digestibility while simultaneously reducing the p.esence of anti-nutrients. Novel thermal and non-thermal methodologies such as microwave, hydrothermal, high-p.essure p.ocessing, and ohmic heating can be emp.oyed for p.ocessing millets, thereby diminishing the loss of nutrients. Additional research can be carried out to investigate their imp.ct on the dehulling and p.lishing of millets.

Imp.ct of elevated CO2 (free air CO2 enrichment) was studied on wheat (Triticum aestivum L. var Kundan) growth, yield and p.oteome. Elevated CO2 significantly imp.cted both underground (+24%) and aboveground (+15%) biomass. Grain weight/p.ant and harvest index were increased by 35% and 11.4%, resp.ctively under high CO2. On the other hand, seed p.otein content was decreased by 19% under CO2 enrichment while seed starch and soluble sugar contents were increased by 8% and 23%, resp.ctively. Wheat leaf p.oteomics revealed that 50 p.oteins were showing differential exp.ession. Twenty p.oteins were more abundant while 30 were less abundant. Thirty two p.oteins were identified by MALDI TOF TOF. More abundant p.oteins were related to defense, p.otosynthesis, energy metabolism etc. While less abundant p.oteins were related to glycolysis and gluconeogenesis. Wheat grain p.oteomics revealed that out of 49 differentially abundant p.oteins, 24 were more in abundance and 25 were less in abundance in wheat grains under eCO2 condition. Thirty three p.oteins were identified and functionally characterized. They were found to be involved mainly in carbon metabolism, storage, defence and p.oteolysis. Gluten p.oteins are the major comp.nent of wheat storage p.oteins. Our results showed that both high and low molecular weight glutenins were more in eCO2 wheat seeds while there was no change in gliadin evels. This might alter wheat dough strength. Concentration of grain Cr and As was increased at eCO2 while that of Fe, Cu, Zn and Se were found to be decreased. Dynamics of carbon utilization and metabolic abilities of soil microbes under eCO2 were significantly altered. Our study showed that altered wheat seed comp.sition is cause for concern vis-à-vis nutrition and health and for industries which may have imp.ications for agriculturally dominated country like India.
