CONTENT AND COMPOSITION OF SUGARS AND ORGANIC ACIDS IN STRAWBERRIES, GROWN IN THE RIGHT-BANK FOREST- STEPPE ZONE OF UKRAINE

Garden strawberry is a valuable berry crop in Ukraine, the harmonious taste of its berries depends on ratio sugars and organic acids. Among factors affecting quantitative qualitative composition acids berries, area cultivation pomological variety are distinguished. The article presents results studies Dukat, Honey Polka varieties grown Right-Bank Forest-Steppe zone Ukraine for content using methods high-performance liquid chromatography an Agilent Technologies chromatograph (model 1100) carbohydrate chromatographic column size 7,8×300 mm, "Supelcogel-C610H". It was found that sugar during research period ranged from 5.0 to 8.6%. Berries were distinguished by significantly higher level – reducing according average data, 4.9-7.7%. investigated varieties, had lowest minimum amount 3.2%. mass fraction fructose 2.1-4.4%, which 42.0-51.1% sum sugars, while glucose 1.1-3.5% (22.0-40.7%) small sucrose - 0.3-1.3, 6.0-15.1% total berries. According dispersion analysis, no significant influence found. three fluctuated within limits 0.9-1.4% depended maximum Dukat 1.4%. Organic strawberries represented citric malic with dominance acid 57.0-68.1% content. A noted variety, Ducat apple acid. sugar-acid index all studied exceeded value 5.3, made it possible determine as sweet sour. In lower due high
