The possibility of long storage of the salty semifinished fern Matteuccia struthiopteris ordinary, obtained by dry salting with high concentration of salt is studied. The dynamics of the chemical composition and quality indicators is investigated. The optimum periods of storage of the semifinished products prepared using different technological modes are defined. Positive influence of short-term scalding of raw materials before salting, essentially reducing autolytic activity of tissue enzymes and quantity of microorganisms in raw materials is noted. It is established that within the first six months of storage the quality of the semifinished product continued to correspond to the necessary requirements. A longer storage of the fern salted without preliminary scalding leads to essential decrease in quality and food value, while the semifinished product obtained with preliminary thermal processing, is stored within twelve months without essential deterioration.

DYNAMICS OF THE BASIC FOOD SUBSTANCES OF THE WILD-GROWING AND CULTIVATED FROZEN BLACKBERRY DURING STORAGE
In the article the results of research on dynamics of the basic food substances of the frozen wild and cultivated blackberry (moisture, sugars, organic acids, anthocians and pectinaceous substances) in the course of storage are presented. It is revealed that with different forms and pomologic grades of blackberry the trends of the processes are almost identical, the quantity of sugars gradually decreases during the whole period of storage, the hydrolysis of sucrose and pectinaceous substances takes place which involves the changes in organoleptic characteristics. High provision of the investigated blackberry with phenolic compounds namely anthocians, characteristic of the given berries, is marked. By the results of the research the conclusion is drawn that the more the provision of blackberry with solids, mainly sugars, and the less free moisture, the safer the original content is
Optimum conditions and keeping periods for canned pickled mushrooms are substantiated, taking into account the changes in their chemical composition, microbiological parameters, toxicological safety. The research of the changes in the carbohydrate content, nitrogen compounds, microbiological and sensory characteristics of canned pickled sub-sour and distinctly sour tubular and lamellar mushrooms of the highest and first class quality was carried out. It was shown that in the process of long-term storage the above stated changes were due, primarily, to the temperature of storage and concentration of acetic acid. Recommended conditions of sterilization allow to retain high nutritional quality of the tinned foods, bring about stability for their keeping in refrigerators and in unregulated environment, with the exception of sub-sour canned food, which are to be stored in special conditions.
