Sorption isotherms and thermodynamic analysis of seed fruits used to obtain vegetable oil
(2015-01-01)
Sorption isotherms of papaya, melon and grape seeds were determined and thermodynamic properties compared. The experiments were carried out at different temperature using the gravimetric method. The Henderson and GAB models ...

Effect of grape seed extract (Vitis labrusca L.) on soybean oil under thermal oxidation
(2017-01-01)
Purpose: This study aims to evaluate the effect of grape seed extract on the thermal oxidation of soybean oil. Design/methodology/approach: Four treatments were used: soybean oil (SO), butylhydroxytoluene (BHT), antioxidant ...
Synthesis and thermal study of polymers from soybean, sunflower, and grape seed maleinated oil
(2017-10-01)
This paper presents the synthesis of some polymers from maleinated vegetable oils (soybean, sunflower, and grape seed) and glycerol. First, all the vegetable oils were previously maleinated with maleic anhydride, then, the ...
Aproveitamento de resíduo de vitivinicultura a partir da extração e aplicação do óleo de semente de uva
(Universidade Tecnológica Federal do ParanáFrancisco BeltraoBrasilEngenharia QuímicaUTFPR, 2019-07-05)
The vitiviniculture is expressive in the south region of Brazil, and has gained field in all corners of the country. This activity result in an amount of residue of an average of 210 thousand tons per year, and of these ...
Towards integral utilization of grape pomace from winemaking process: A review
(Pergamon-Elsevier Science Ltd, 2017-07)
Grape is the main fruit crop in several countries. Although many grape-based food products can be found in the market, studies have shown that around 75% of the world grape production is destined for the wine industry. ...
Enzymatic synthesis of structured lipids from grape seed (Vitis vinifera L.) oil in associated packed bed reactors
(2020-01-01)
Triacylglycerols (TAGs) can be modified to increase the absorption of fatty acids, prevent obesity, and treat fat malabsorption disorders and metabolic diseases. Medium–long–medium (MLM)-type TAGs, which contain medium-chain ...
