abstract: acidophilus milk after preparation, with the defined characteristics of ph, titratable acidity and viable counts of lb. acidophilus, was kept at the refrigerator (5 °c) and changes of above mentioned parameters were evaluated during 21 days at 7-day intervals. the obtained results showed that the titratable acidity of product significantly (p≤0.05) increased over storage period, demon...

The changes in some physicochemical properties, sugar, organic acid and volatile compound contents fresh Verdani grape (Vitis vinifera L.) juice (FGJ) were evaluated the production of its traditional molasses (pekmez). After production, total soluble solid (TSS), titratable acidity (TA), glucose, fructose, malic, citric succinic concentrations increased (P

Peaches are one of the most popular fruits around globe. Selecting optimum harvesting maturity for peaches is crucial in assuring high-quality fruits. This study a model determining ideal harvest time robot harvester. Our was carried out over two years on ‘Mihong’ during days after full bloom (DAFB) 71 to 90 2021 and DAFB 64 84 2022 select optimal index through quality survey. The fruit size, s...

The objective of this study was to evaluate the quality strawberries distributed in global markets. We obtained from Egypt, Mexico, Republic Korea, Spain, and United States America (US) being sold Singapore, compared them with Japanese (cv. Benihoppe) using instrumental analysis sensory evaluation. Sensory evaluation conducted by Singaporean assessors. results showed that Egypt were relatively ...

S.P.L. Sgrensen not only introduced the p H concept, but in his classical paper from 1909 “Enzymstudien 11” he also described in great detail the colorimetric as well as the potentiometric methods for p H measurement, and he pointed out that two kinds of acidity must be distinguished: Actual acidity and titratable acidity. Previous to Sgrensen the acidity of a solution was usually determined by...

Abstract The objective of this study was to determine the relationship among dry matter content (DMC) and maturity indexes at harvest quality ‘Gala’ apples after storage. Apple fruit four strains produced on two rootstocks three growing regions were used for experiments 1 2. For all experiments, assessed one day stored removal from storage plus seven days 22 °C. experiment 1, harvested weekly a...

effect of different fruit position on postharvest quality of f1 hybrid redfleshed watermelon hi-u 16 was examined. in this study only one main vine was trained and maintained. the plants were allowed to set three fruits naturally at the first (8th - 11th nodes), second (13th - 16th nodes) and third (18th - 21th nodes) position. fruits were harvested at 35 days after anthesis. fruit weight, diam...

Fruit ripening in response to treatments with propylene, 1-methycyclopropene (1-MCP), and low temperature was characterized in 'Sanuki Gold' kiwifruit, Actinidia chinensis Planch. Propylene treatment immediately induced rapid fruit softening, increased AC-PG (polygalacturonase) and AC-EXP (expansin) mRNA accumulation, and stimulated an increase in the soluble solid concentration (SSC) and a dec...
