One of them is nano-dipeptide soap made from industrial by-products and its making presented by the Nano Materials Institute of the State Academy of Sciences to the national nano sci-tech exhibition-2017 held late in October.

Meanwhile, scientists of the Fermentation Research Institute under the Food and Consumer Goods Research Institute created a new technology for making ferments to produce fermented soybean powder.

They confirmed sci-tech indices to all the production processes ranging from liquid culture to drying, so as to lay a firm foundation for mass-producing fermented soybean.
