In fruits and vegetables, browning occurs due to the oxidation of polyphenols. Oxidative browning is catalysed by polyphenol oxidase (PPO; monophenol, dihydroxyphenyl alanine:oxygen oxidoreductase; EC.1.14.18.1). When fresh products are damaged oxidative browning occurs, and this is an economic problem for producers and consumers. Polyphenoloxidase, which is a copper-containing enzyme, catalyse...

Rapid color degradation during processing and storage is a limitation when using strawberry puree (SP). This work aimed to use image analysis coupled with two machine learning algorithms: ordinary least squares (OLS) artificial neural networks (ANNs), predict anthocyanin content (AC) in frozen SP its at –18°C for 120 days. When applying the OLS regression model, unsatisfactory AC prediction val...

Oxidation processes in milk and yogurt during the shelf life can result in an alteration of protein and lipid constituents. Therefore, the antioxidant properties of yogurt in standard conditions of preservation were evaluated. Total phenols, free radical scavenger activity, degree of lipid peroxidation, and protein oxidation were determined in plain and skim yogurts with or without fruit puree....

Spray-drying, which has been used for commercial production of functional ingredients from several fruits and vegetables, has not yet been studied for sweetpotato processing. Thus, the objective was to determine the effects of viscosity reduction of sweetpotato puree with alpha-amylase, maltodextrin (MD) addition, and inlet air temperature on the physicochemical characteristics of spray-dried s...

The research carried out to evaluate effects of quince rootstocks [Quince Province BA29 (BA29), Quince A(QA), C (MC)], pear cultivars, and years on fruit quality yield efficiency in the 2020-2021. highest weight was obtained from (196.02 g), lowest MC (158.09 g). In cultivars ‘Abate Fetel’ (210.85 ‘Santa Maria’ (156.73 number fruits (17.06 pieces tree-1), per tree (3.13 kg hectare (5982.8 ha-1)...

This study was carried out to evaluation of the effects on pruning weight (kg plant-1), cumulative per plant and hectare ha-1) 3 quince rootstocks [Quince BA29 (BA29), Quince A (QA), C (MC)] pear clonal (Fox11, OHxF333, Farold 40) seedling grafted with 4 standard cultivars (‘Abate Fetel’, ‘Deveci’, ‘Santa Maria’, ‘Williams’) between 2019-2021 years. Rootstocks, cultivars, research years their i...
