[Green] "Tangerine by-products" that I used to pay for.Presenting a Resource Model

A model was proposed to resource citrus by-products that had been discarded for money.

The Rural Development Administration said it has developed a base technology that increases drying efficiency and maximizes functional ingredient extraction for industrialization of high value-added materials of citrus by-products.

In Korea, tangerine by-products are generated between 50,000 and 70,000 tons every year, and it is estimated that the processing cost is 1.5 to 2 billion won per year.

Citrus by-products are rich in flavonoid ingredients such as Hesperidine and Narirutin, which are effective in antioxidants and anti-inflammatory, so they are highly valuable as functional materials.

However, there was a limit to material industrialization due to the difficulty of materialization processes such as drying due to high sugar and moisture.

Researchers at the Rural Development Administration said, "Cold to increase the drying efficiency of citrus by-products?"After thawing, it was treated with enzymes and alcohol, and established a technology for hot air drying.

This is a useful technology that dries to 12% moisture level compared to hot air drying (50-54%) alone.

In addition, as a result of applying citrus by-products-derived functional ingredient extraction technology, 40% of alcohol and ultrasound were repeatedly treated to obtain the most functional substances (hesperidin, nalirutin).

The Rural Development Administration plans to transfer technology to industries that manufacture food, cosmetics, and pet food and distribute citrus by-products materialization technology to the site.
