The actual status of production, management and export of 96 traditional food processing companies which supported by the government in Kyungpook province were investigated. Governmental support contributed to the increase of farmhouse income, employment and depreciation of agricultural products a bit, but it was supported mostly to unexperienced party. Technologies for food processing developed in institute and college were little. 42 percent of packaging design was developed by service commission, but the agency was very limited. Total export price in 1996 was 2.3 billion Won, but it was decreased in 1997. The responce to the prospect of traditional food processing work, 37.5 percent replied that this work can bring up as exportable product, but ambiguious response was a little. To settle a weakness of farming food processing work, the establishment of special marketing comapny was required and this company should accomplish marketing advertizing and exporting business.

This study was performed to determine chemical compositions of dried persimmons stored with plastic film at low temperature and the effect of film packaging on dried persimmons during storage. The moisture contents of dried persimmons were 30 to 36% and alcohol contents were 264 to 318 mg/100g and acetaldehyde contents were 25 to 40mg/100g. Total lipid contents of dried persimmon were 626 to 869mg/100g and oleic, palmitic, linolenic, and palmitoleic acid were major fatty acids in total lipids. Major amino acids were glutamic acid, arginine, cystine and aspartic acid. From the result of storage experiment, non-packed group was that hardness was high as decreased in moisture content. In case of film packed groups stored at 5, self life was longer than non-packed and packed groups stored at room temperature. But, it need to develop available packing material and storage method.

This study was conducted to understand the characteristics of fruit softening during ripening which causes deep loses in quality of horticultural products during storage and marketing process after harvest. The changes of cell wall components during ripening was investigated. The climacteric rise was between 42 and 49 days after anthesis and then decreased. Ethylene evolution was similar to respiration. The hardness of fruit decreased markedly at this climacteric period and significances of textural parameters among the ripening periods were recognized but the significance between 50 and 55 days after anthesis was not. Sugar components of cell wall polysaccharides were uronic acid, galactose, glucose, arabinose, xylose, rhamnose, mannose and fucose. The contents of arabinose and mannose in alcohol-insoluble solids fraction increased, but other sugars were not changed. In cell wall fraction, the contents of uronic acid, galactose, glucose and arabinose were comparatively high, but galactose, arabinose and ironic acid were decreased markedly during ripening. ironic acid occupied above 75% of total monosaccharide in pectin fraction and decreased markedly during ripening. In acid-soluble hemicellulose fraction, the contents of uronic acid, glucose, galactose and rhamnose were high and they decreased from 50 days after anthesis. The contents of glucose and xylose were high in a alkali-soluble hemicellulose fraction and they decreased markedly at 55days after anthesis.
