Storage of ‘Fuji’ apple fruit in a high CO2 (3 kPa) and low O2 (1.5 kPa) controlled atmosphere (CA) reduced firmness and titratable acidity (TA) loss during long term storage. This CA environment also induced development of internal CO2-injury (brown-heart) and slowed the disappearance of watercore. The symptoms of internal CO2-injury were first detected 15 days after CA establishment and the s...

OBJECTIVES To measure, in vitro, the pH and titratable acidity (TA) of various soft drinks and to assess the erosive effect of smoothies using an in situ model. METHOD The in vitro phase of this study included measuring the inherent pH of six different commercially available smoothies, diet coke, and citric acid 0.3% (positive control) using a pH meter. The TA was determined by titration with...

In the present study, we calibrated and validated thermal models to predict DOY date at which grape maturity index, potential alcohol/total acidity (PA/TA), reaches 0.75 (MS0.75), 1.0 (MS1), 1.5 (MS1.5), 2.0 (MS2) for two grapevine Portuguese varieties, Touriga Nacional (TN) Encruzado (EN), growing in Dão wine region, Portugal. Daily rates of forcing calculated with Sigmoid (SM) function Degree...

Orang drink is the most common flavoured consumed in Iraq and it can be found markets of all sizes provinces making them subjected to a wide range storage temperature time. In this work, effect time was studied on three different local brands Orange with Low-to-No nectar content; were packed Laminated Aseptic Cartons (LAC). Samples stored fixed controlled environment ranging between 10 ?C-50 ?C...

Phosphorus (P) is one of the most limiting nutrients for growth and development crops, important soil fertility managements, since it affects quality fruits. With hypothesis that different levels irrigation phosphorus fertilization interfere in physical physicochemical properties tomatoes, objective this experiment was to verify analyze behavior fruits’ responses. The conducted a greenhouse at ...

The aim of this study was to evaluate and compare potential different optical spectroscopic techniques for quality assessment apple juices. calibration partial least squares (PLS) regression models were developed optimized determination parameters juice non-destructively from the NIR spectra fruit or directly UV-VIS-NIR external validation performed using test sample set. Calibration based on c...

to prolong the storage life and quality of 'zafarany' peach, fruits were treated with uv-c irradiation with dosage of 1.435×10-4 wcm-2 with three time durations (0, 5 and 15 min) and as well immersion of fruits in 0 and 3% cacl2 solution. the experiment was carried out in a completely randomized design (factorial experiment) of four replications. fruits were harvested in commercial ma...

Changes in physicochemical traits, peel colour, and juice attributes of four blood orange cultivars (‘Moro’, ‘Tarocco’, ‘Sanguinello’, ‘Sanguine’) were evaluated during 180 days at 2 5 °C plus 20 for shelf life. ‘Tarocco’ had the lowest weight firmness losses both temperatures storage. Titratable acidity (TA) was higher than °C, with ‘Sanguinello’ showing highest TA, respectively. Juice content...

This study examined the effect of locule position and thawing duration on physicochemical nutritional characteristics intact cryo-frozen Musang King durian fruit. Cryo-frozen that had 5 locules was thawed for 2 18 hr, fruitlets each were analysed colour (L*, a*, b*, C*, h), firmness, soluble solids concentration (SSC), titratable acidity (TA), pH, ascorbic acid (AA), total phenolic content, fl...

effect of calcium chloride on tomato quality and shelf life of petoearly ch, koral and rio grand tomato cultivars were studied at the agricultural and natural resources research center of west azerbaijan, iran over 2002-2003. a calcium chloride solution in 0,0.5% and 1% concentrations was sprayed on the tomatoes three times. the fruit was harvested at the mature green stage and stored in cold s...
