Pyrolysis of sunflower seed hulls for obtaining bio-oils
(Elsevier, 2014-12-04)
Bio-oils from pyrolysis of as received sunflower seed hulls (SSH), hulls previously washed with acid (SSHA) and hulls submitted to a mushroom enzymatic attack (BSSH) were analyzed. The concentration of lignin, hemicellulose ...
Changes in quality and composition of sunflower oil during enzymatic degumming process
(Elsevier Science, 2014-02-14)
The objective of this study was to examine the effect of the enzymatic degumming process on composition of crude sunflower oil. To analyze the crude and degummed oils, different parameters were determined. Phosphorous ...
Effects of whey protein concentrate on shelf life of cookies using corn and sunflower oils
(Science Publishing Group, 2014-07)
The objective of this work was to study the effect of whey protein concentrate (WPC) on shelf life of cookies using corn and sunflower oils as fat source. Wheat flour was partially replaced by WPC with levels of 5, 7.5, ...
Tocopherol oil concentration in field-grown sunflower is accounted for by oil weight per seed
(Springer, 2004-12)
Tocopherols are natural antioxidants that increase the stability of fat-containing foods and perform important biological activities. Significant variations (389 to 1873 μg g oil-1) in the total tocopherol concentration ...
Performance of Green Solvents in the Extraction of Sunflower Oil from Enzyme-Treated Collets
(Wiley VCH Verlag, 2021-01-01)
The main goal of this work is to evaluate the extraction of sunflower oil from enzyme-treated collets using ethanol and isopropanol (IPA) as solvents. The sunflower collets are pretreated with the multienzyme complex ...
Chemical Characterization of Oils and Meals from Wild Sunflower (Helianthus petiolaris Nutt)
(Springer, 2004-12)
Chemical characterizations of oils and meals from the wild sunflower species Helianthus petiolaris Nutt and their comparison with those from cultivated sunflower (H. annuus) were performed. Seeds from indigenous populations ...
Antioxidant Activity of Essential Oils Extracted from Aloysia triphylla and Minthostachys mollis that Improve the Oxidative Stability of Sunflower Oil under Accelerated Storage Conditions
(Wiley VCH Verlag, 2018-08)
This research determined the antioxidant properties of the essential oils from Aloysia triphylla (AT) and Minthostachys mollis (MM), their antioxidant activity in sunflower oil during accelerated storage (60 °C), and how ...
Temperature-dependent diffusion coefficient of oil from different sunflower seeds during extraction with hexane
(Elsevier, 2011-07-17)
Oil extraction from confectionery, oilseed and wild sunflower seeds with n-hexane was investigated by laboratory tests carried out in a stirred batch extractor at several temperatures (40, 50 and 60 °C). The rates of ...
Partial hydrogenation of sunflower oil: Use of edible modifiers of the cis/trans-selectivity
(Elsevier Science, 2009-02)
The partial hydrogenation of sunflower oil with minimum trans-isomer formation is studied, using a Pd/γ-alumina catalyst modified with promoters apt for human consumption: ethyl benzoate and magnesium glycinate. It was ...
