Arthrospira platensis, commonly known as Spirulina, is a photosynthetic filamentous cyanobacterium (blue–green microalga) that has been utilized food source since ancient times. More recently, it gained significant popularity dietary supplement due to its rich content of micro- and macro-nutrients. Of particular interest water soluble phycobiliprotein derived from Spirulina phycocyanin C (C-PC), which stands out the most abundant protein in this cyanobacterium. C-PC fluorescent protein, with...

Abstract Wheat germ oil (WGO) is a specialty product with very high nutritional value. The chemical composition of both commercial and pilot scale supercritical carbon dioxide (SC‐CO 2 ) processed WGO was examined. This study showed that methods used for extraction refining did not have significant effect on the fatty acid oil. SC‐CO extracted had higher tocopherol content than commercially hexane phospholipid low indicating method could eliminate degumming step from edible processes....

Herb consumption in United States has grown significantly over the last twenty years. A review of overall herb imports into U.S. shows that oregano import is largest quantity and dollar value. Thymol carvacrol are two major compounds essential oil obtained from Mexican oregano. These special interest due to their antioxidant antimicrobial properties. In this study, effect moisture on growth (Lippia berlandieri Schauer) its thymol composition was examined greenhouse tests. The crop yield...

Microencapsulation improves oxidative stability and shelf life of fish oil. Spray freeze drying are widely used to produce microcapsules. Newer spray-nozzles utilize multiple fluid channels allowing for mixing wall core materials at the point atomization. Sonic energy has also been employed as a means The objective this study was examine effect nozzle type design on oil encapsulation efficiency microcapsule properties. A total 3 types, pressure with 1 liquid channel, 2 channels, sonic...

Policosanol (PC) is the common name for a mixture of high molecular weight (20−36 carbon) aliphatic primary alcohols, which are constituents plant epicuticular waxes. Wheat germ oil has been reported to improve human physical fitness, and this effect attributed its PC, specifically octacosanol (OC) content. Although PC composition wheat leaves studied extensively, information on content grain fractions scarce. The objective study was examine contents compositions 31 varieties grown in...

ABSTRACT: Supercritical carbon dioxide (SC–CO 2 ) fractionation technique was evaluated as an alternative process for reducing the free‐fatty‐acid (FFA) content and minimizing phytosterol loss of rice bran oil (RBO) during process. The effects pressure (20.5 to 32.0 MPa) temperature (45 80 °C) isothermal operation column on composition resultant fractions were examined. Low‐pressure high‐temperature conditions found be favorable triglycerides (TG) losses FFA removal from crude RBO. Rice with...

ABSTRACT Lipid composition of supercritical CO 2 (SC‐CO ) extracts, residual oil in muscle and changes sarcoplasmic proteins after extraction Atlantic mackerel were characterized. Dehydration the to 10.2% (w/w) resulted high yield with minimum protein content composition. Sarcoplasmic fish following SC‐CO treatment was lower than that original muscles at all moisture levels (3.8–64%, w/w). Analysis by capillary electrophoresis indicated aggregation low molecular weight during extraction....

Abstract Biofuels derived from microalgae are considered a viable alternative energy resource that eliminates the major drawbacks associated with biofuels produced land crops. Strain selection is critical factor for success of microalgal production systems. This study evaluates Picochlorum oklahomensis (PO) as potential microalga strain biofuel and bioproduct applications. Nannochloropsis oculata (NO) was included in well‐studied reference biomass properties suitable commercial Growth...

Abstract The potential use of supercritical (SC)‐CO 2 /ethanol mixture for the extraction and fractionation phospholipids (PL) from flaked canola seeds, meal, acetone insolubles (AI) was investigated. PL possible when ethanol used as a cosolvent in SC‐CO . recovery 20.8% achieved flakes were extracted at 70°C 55.2 MPa with /10% EtOH after iol removal neat Soaking meal prior to /EtOH increased 30.4%. content extracts decreasing triglyceride concentration feed material increasing amounts added...

This study examined the chemical composition and antioxidant properties of extracts obtained from two byproduct streams generated at a commercial pecan nut shelling operation. Byproduct stream F contained more meat pieces packing material than S, consisting mainly hard outer shell pieces. Samples Native variety nuts were processed using subcritical, sonication aided microwave heating, water as solvent. Ferric reducing capacity (FRAP), Total Phenolic Content (TPC),...

Microalgae-based renewable energy, industrial chemicals, and food have received great attention during the last decade. This review article highlights versatility of algal biomass as a feedstock for producing various commodities high-value products, including aromatic hydrocarbons lipids within biorefinery systems. Lipid content composition cultivated in media, specifically wastewater streams generated at agricultural production facilities, are reviewed. Technical chemical aspects conversion...

ABSTRACT Canola flakes obtained before and after conventional cooking were extracted with supercritical carbon dioxide (SC‐CO 2 ) at 35–75°C 20.7–62.0 MPa. Moisture content was adjusted to 12.7–42.5% (w/w, moisture‐and oil‐free basis). of residual extraction monitored. Amount extract recovered increased increasing temperature pressure, except 20.7 MPa pressure it decreased indicating a crossover the solubility isotherms. Some water co‐extracted canola oil. Free fatty acid (FFA) concentration...
