In this study, the effectiveness of chitosan coating treatment to control weight loss and maintaining fruit quality of apricot was investigated. Fruits were coated with 0.25%, 0.5% and 0.75% chitosan as well as distilled water (control). Following treatments, fruits were stored at 0?C and 80 ? 2% relative humidity for 25 days. The weight loss, total soluble solids (TSS), titratable acidity (TA)...

BACKGROUND: Total phenolics content, antioxidant activity and cytotoxicity of the methanol extracts from leaf parts of 13 Korean traditional salad plants were investigated in order to determine their properties. RESULTS: The highest phenolics content (mg ferulic acid equivalents kg−1 dry weight (d.w.), omit one) was found in methanol extracts from Polygonum aviculare, at 293.7 ± 6.0, followed b...

The changes in total polyphenolics in elderberry (Sambucus nigra) following treatment with various doses of pulsed ultraviolet rays (UV) were investigated. Four pulsed UV durations (5, 10, 20, 30 seconds) at three energy dosages (4500, 6000, 11,000 J/m/pulse) were considered for the research. All treated elderberry fruits were incubated for 24 h at room temperature (25 ̊C) following treatment to...
