Drying Accelerators to Enhance Processing and Properties: Ethanol, Isopropanol, Acetone and Acetic Acid as Pre-treatments to Convective Drying of Pumpkin
ABSTRACT Different drying accelerators were studied to improve vegetable drying: acetone (AC), ethanol (ET), isopropanol (ISO) and acetic acid (AA). Pre-treatments were performed by immersion of pumpkin cylinders. Convective ...
Starch modification by ozone: Correlating molecular structure and gel properties in different starch sources
ABSTRACT Cassava, corn and potato starches were subjected to ozone processing under the same conditions, in order to allow comparisons. The molecular structure was evaluated using two chromatographic analyses: high-performance ...
Biodegradable foam tray based on starches isolated from different Peruvian species
ABSTRACT Starch was isolated from three Andean-native crops — arracacha (Arracacia xanthorrhiza), oca (Oxalis tuberosa), and sweet potato (Ipomoea batatas) — for use as a raw material for the production of foam trays. The ...
Use of fumaric acid to control pH and inhibit malolactic fermentation in wines
(Taylor & Francis, 2019-11-07)
ABSTRACT Fumaric acid is an additive allowed by the Codex Alimentarius and under evaluation by the International Organisation of Vine and Wine (OIV) that can be used for wine acidification but also to inhibit malolactic ...
Impact of pre-drying and frying time on physical properties and sensorial acceptability of fried potato chips
ABSTRACT In this work the effects of pre-drying and frying time on colour, oil, texture and sensorial acceptability (overall liking) of potato chips were evaluated. Potato chips were pre-dried for 0, 10, 20 and 30 min at ...
Thermal stability of anthocyanins in grape skin extracts from red winemaking residues
ABSTRACT The stability of anthocyanins in extracts from red grape skins after applying dehydration temperatures of 40 °C and 150 °C was evaluated. Two fractions of red grape skins: unfermented fresh grape skins (F) and ...

RESUMEN El presente trabajo tuvo como objetivo caracterizar física, funcional y estructuralmentemente los almidones extraídos de cinco variedades de papas nativas (Solanum tuberosum) var. Andígena: Águila (AG), Bretaña ...
Effect of metabolic inhibitors on the alcoholic fermentation: tolerant yeasts
RESUMEN El objetivo de este trabajo fue evaluar el efecto de diferentes inhibidores metabólicos sobre la fermentación alcohólica por dos cepas de Saccharomyces cerevisiae: 7VA y AWRI796. Estos inhibidores se producen ...
The addition of sugarcane bagasse and asparagus peel enhances the properties of sweet potato starch foams
(David Shires, 2019-02-11)
ABSTRACT The agro-industrial wastes, sugarcane bagasse (SB) and asparagus peel (AP), were used to enhance the properties of biodegradable foam trays based on sweet potato starch-based foam trays (starch/SB and starch/AP ...
