The aim of this study was to investigate the effectiveness of ultrasound as a conservation method for the inactivation of Escherichia coli inoculated into cactus pear juices (green and purple). Total soluble solids, pH, titratable acidity, and the kinetics of E. coli in cactus pear juices treated by ultrasound (60%, 70%, 80% and 90% amplitude levels for 1, 3 and 5min) were evaluated over 5 days...

The purpose of the study was to compare basic fruit chemical composition of four highbush blueberry cultivars: ‘Spartan’, ‘Bluecrop’, ‘Jersey’ and ‘Blueray’. The plants were grown on plantation near Szczecin in the years 2001 – 2003. Basic chemical composition of fruit including total ash, crude fibre, total nitrogen, soluble solids, titratable acidity, dry weight and total polyphenol content w...

Abstract The objective of this study was to assess the effects post-bloom (PB) or preharvest (PH) treatments ‘Braeburn’ apple trees with prohexadione-calcium (ProCa; 300 mg L-1), an inhibitor gibberellins biosynthesis, GA4+7 (300 L-1) on fruit quality at harvest and after storage (four months 0±0.5 oC, followed by five days shelf life). PB started 15 full bloom, one application every week six a...

The objective of this study was to evaluate irrigation levels in tomato crops, using economical beds with mulch. A randomized block design within a split-plot had run 2 x 5 factorial treatment scheme structure, four replications. plots were the five (50, 75, 100, 125, and 150%) crop Evapotranspiration (ETc), subplots two varieties RASTEIRO RIO GRANDE (RR) (Lycopersicon lycopersicum) CALINE IPA-...

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 objective of this study was to determine important chemical characteristics of a full-strength liquid smoke, Code 10-Poly, and three refined liquid smoke products (AM-3, AM-10 and 1291) commercially available (Kerry Ingredients and Flavors, Monterey, TN). The pH of the products were significantly different (P < 0.05) and ranged from 2.3 (Code 10-Poly) to 5.7 (1291). The pH was inversely cor...

The current paper presents the coating of harvested strawberries with edible nanoparticles Chitosan. NPs were formed by application ultrasonic waves on an acidic solution chitosan. In a one-step process created and subsequent to their formation they deposited surface. shelf life coated was compared deposition same amount non-sonicated chitosan, i.e., individual chitosan molecules fruit. charact...

mango (mangifera indica l.) production is on the rise in various subtropical zones throughout the world. the cultivation of this fruit tree is feasible along the coast of granada, where some 1,500 ha are presently grown. in 2006, the eu exported 118 thousand tonnes of mangoes at a value of 131 million euros. this study was conducted to assess the physico-chemical quality characteristics of some...

Five strawberry (Fragaria × ananassa Duch.) cultivars were grown in Queensland, Australia to determine whether higher temperatures affect production. Transplants planted on 29 April and data collected growth, marketable yield, fruit weight the incidence of small less than 12 g until 28 October. Additional soluble solids content (SSC) titratable acidity (TA) from 16 September Minimum 2 °C 4 long...
