## 【Abstract】

Aims of this project are to develop regional network for the advanced utilization of residues from starch factories and achieving food safety using advanced science and technology. Cosmo Foods Co., Ltd. and Tokachi Foundation developed technology for potato peptide production from residues of the starch factories. Obihiro University has clarified that the potato peptide has favorable health functions related to lipid metabolism and anti-oxidative effect in animal experiments. Further, it has become successful in developing functional food containing potato peptide.

## 【Summary of the technology transfer】

Technological Impact

• Establishing extracting method of potato peptide from residues from starch factories

• Potato peptide is good as soy peptide and has favorable health functions

• Production of functional foods

## Market Impact

If this becomes successful there will be a good demand for functional foods produced from potato peptide in the market.

Market research in Japan

2007: 300,000,000 yen

2012: 1,000,000,000 yen - 1,500,000,000 yen

## ●Social Impact

Residues from starch factories are combusted using considerable amount of energy and it may pollute the environment. Therefore, it is believed that there may be a ripple effect of reduction of agriculture industrial waste for society.

## ●Special Features of the Collaboration

This project is funded by Cooperation of Innovative Technology and Advanced Research in the Evolutional Area (City Area) of the Ministry of Education, Culture, Sports, Science and Technology of Japan. The aim of this project is to develop value added functional food products from agricultural and livestock products in Tokachi area. By this project, it would develop a cooperate research network among research institutions and companies.

## Project Background

This project is the City Area Program of the Ministry of Education, Culture, Sports, Science and Technology of Japan. By this project, it would develop a cooperative research network among research institutions and companies.

## Funding History

This project is supported by a grant from Cooperation of Innovative Technology and Advanced Research in the Evolutionary Area (City Area) of the Ministry of Education, Culture, Sports, Science and Technology of Japan, 2005.
