BACKGROUND Total phenolic content (TPC) and antioxidant activity (AA) assays in microplates save resources time, therefore they can be useful to overcome the fact that conventional methods are time-consuming, labour intensive use large amounts of reagents. An intra-laboratory validation Folin–Ciocalteu microplate method measure TPC 2,2-diphenyl-1-picrylhydrazyl (DPPH) AA was performed compared with spectrophotometric methods. RESULTS To compare methods, confidence intervals a linear...

Hybrid and plant-based products are an emerging trend in food science. This study aimed to develop three patty prototypes (meat, hybrid, plant-based) enhanced with vegetable fat replacement broccoli extract using a soy allergen-free protein matrix treated high hydrostatic pressure (HHP) sous vide cooking create sustainable nutritious burger alternatives. The samples were evaluated for microbiological safety, proximal composition, physicochemical properties, sensory characteristics, carbon...

ABSTRACT The thin-layer drying behaviour of vegetable wastes (as a mix lettuce and cauliflower leaves) from wholesale market for temperature range 50-150°C was determined. Drying this material found to take part only in the falling-rate period. experimental data were fitted simple exponential model Page model. Both models have good prediction capability, Effective diffusion coefficient varied 6.03*10-9to 3.15*10-8m3/s with an activation energy 19.82 kJ/mol. dependence effective expressed by...

Worldwide, tomato production is estimated at 180 million tons per year, which generates a byproduct with highly variable characteristics and volumes. According to the principles of circular economy, semi-industrial method for integral use as an ingredient in bakery industry proposed. Using two different dehydration processes (convection or freeze-drying), formed by peels seeds was stabilized ground into flours that were used ingredients focaccia-type flatbread elaboration through wheat flour...

Natural plant extracts have emerged as a potential alternative to sulphites in minimally processed potatoes. The aim of this study was evaluate the inhibitory capacity various on potato polyphenol oxidase (pPPO) and optimize extraction conditions for preventing browning fresh-cut potatoes (cv. Monalisa). Fifteen aqueous were characterized by their total phenolic content (TPC), antioxidant activity (AA) pPPO. Clove extract showed highest TPC AA among all extracts. Garlic, green tea wheat bran...

The effects of non-thermal, high-hydrostatic-pressure processing (HPP) and its combination with sous vide cooking technique (HPP-SVCOOK) on physicochemical traits veal patties elaborated top sirloin caps (Biceps femoris) derived from local Pyrenean bullocks, were investigated. subjected to 13 treatment combinations three HPP pressures (350, 475, or 600 MPa) for 5, 10, 15 min, followed by 20 subsequent SVCOOK at temperatures (55, 60 65 °C). Significant changes in color texture parameters...

Lycopene is usually extracted from the by-product of tomato industry using organic solvents (OS) in combination with a physical technique. An emerging technique high-pressure processing (HPP). This study aims to find method by applying green solvent (edible vegetable oils) an HPP-assisted solid-liquid extraction. Three dosages (10%, 20%, and 40%, w/v) were tested OS, sunflower oil (RSO), extra-virgin olive (EVOO). recovery increased ratio oil, particularly when EVOO. In another stage study,...

Abstract Research on the management of broccoli crop residues and surpluses is critical for improving agricultural practices, optimizing food industrial manufacture, contributing to better human nutrition. The objective this study was obtain novel ingredients based these a wide range applications in industry. effect air-drying (60 °C or 80 °C) applied field (broccoli stalks), mimicking conditions, compared with dehydration by freeze-drying same whole plant). Thus, different flours were...

Abstract Equilibrium Moisture Content (EMC) data for medium rough rice grain, Lido variety were obtained by equilibrating samples at different Relative Humidities (ERH) and Temperatures. The employed models to fit the GAB, modified Chung-Pfost, Halsey, Modified Henderson, Oswin. evaluated using standard error of moisture content, mean relative (%P) model correlation coefficient r2. GAB indirect regression described EMC best, however its parameters lacked physical meaning. Chung-Pfost...

Andean blackberries are highly perishable due to their susceptibility water loss, softening, mechanical injuries, and postharvest diseases. In this study, the antimicrobial efficacy of gaseous ozone against spoilage (mesophiles, psychrotrophs, yeasts molds) pathogenic (E. coli, S. enterica, B. cinerea) microorganisms was evaluated during 10 days storage at 6 ± 1 °C. Respiration rate mass loss were also determined. Ozone applied prior 0.4, 0.5, 0.6, 0.7 ppm, for 3 min. The best results...

ABSTRACT The moisture sorption isotherms of dried vegetable wastes (based on green leaves and fruits) from wholesale market were determined at 25, 40, 60 90°C by the static gravimetric method. Experimental data fit using several mathematical models. G.A.B. Halsey model gave minimum mean square error. parameters related with temperature Arrhenius expressions.
