Enrichment of sunflower oil with β‐carotene from carrots: Maximization and thermodynamic parameters of the β‐carotene extraction and oil characterization

Catechins were extracted from black shada, white shada seeds and waste of squeezed grape by mixed each sample with distilled water(1:10), with ethyl acetate(1:1) v/v. Detection of active compounds in the extracts done using IR technique β-carotene bleaching test and peroxide value(POV). Results showed that the black grape seed and the waste of squeezed grape have high antioxidant activity( 64 and 52 g/k grespectively), in comparison with BHT, while it was lower than PG which were 48 and 41.6g/kg compared with PG. On the other hand white grape seed extraction was in the middle between obvious two extractions and was 48 and 36g/kg in comparative with BHT and PG respectively. Peroxide value was determined in sunflower oil for 14 days at 65oc, and showed that these extractions have antioxidant activity and similar to butylated hydroxyl toluene BHT and propyl galate PG.

Sorbaria tomentosa,, commonly known as “Berre” is native to Himalaya and Hindukush range in Pakistan. Qualitative phytochemical screening as well as quantitative antioxidant potential of its ethanolic extract was evaluated. Antioxidant potential of the extract was determined using standard methods like DPPH, FRAP, total phenolics, total flavonoids, ABTS radical cation scavenging assay and β-carotene linoleic acid emulsion system. Cu(II) and Zn(II) chelates of ,,Sorbaria tomentosa,, were also prepared and their antioxidant potential was compared with the extract as well as with synthetic antioxidants (BHT and BHA). It was observed that ,,Sorbaria tomentosa,, is a good source of natural antioxidant that worked efficiently compared to respective chelates. Keeping in view less efficiency of chelated extracts, stabilization studies of sunflower oil were conducted with ethanolic extract (250, 500, 1000 ppm) of ,,Sorbaria tomentosa,,. Various parameters like PV, FFA and IV were estimated to evaluate stabilization of oil. ,,Sorbaria tomentosa,, extract (1000 ppm) showed almost same role during stabilization like BHA at ambient condition during a storage period of 45 days.

Deodorized Oils

The technological parameters, namely temperature and duration of β-carotene extraction process from the biomass of filamentous fungus Blakeslea trispora with vegetable oils of various fatty acid compositions and with various contents of natural antioxidants (refined deodorized sunflower, viso-oleic sunflower, corn and sesame) have been investigated. Statistical models of dependences of β-carotene, as well as analytical numbers, characterizing the content of free fatty acids (acid number) and primary products of lipid oxidation (peroxide number) content, in oil extracts of the specified refined deodorized oils, from temperature and extraction duration have been built. Rational parameters of β-carotene extraction from Blakeslea trispora biomass with selected extractants (refined deodorized sunflower, high oleic sunflower, corn and sesame oils) have been determined for the extracts technological properties control. It has been proven that the use of these refined deodorized oils as extractants practically does not affect the content of the target product in oil extracts of biomass, but it does affect the analytical numbers of extracts characterizing the content of free fatty acids, peroxides and hydroperoxides. The highest content of free fatty acids in β-carotene containing biomass extraction with sunflower oil has been observed. The minimum content of free fatty acids in extracts with corn and sesame oils using has been be achieved. The highest content of primary products of lipid oxidation (peroxides and hydroperoxides) during β-carotene containing biomass extraction by sunflower oil has been observed. The minimum content of free fatty acids in extracts with sesame oil using has been achieved. It is possible to predict β-carotene content, as well as acid and peroxide numbers of oil extracts from biomass in specified refined deodorized oils, depending on temperature and extraction process duration using the obtained approximation dependences.
