“…Also, Dollear et al (14) reported that ariatoxins in prepress solvent-extracted peanut meal were extracted by acetone and water (90: 10). Gardner et al (15) significantly reduced the aflatoxins in cottonseed and peanut flakes by extracting with a ternary solvent composed of acetone-hexane-water (54:44:2). It has also been demonstrated that ethanol and water (80:20) and the ethanolwater azeotrope (95:5) were effective in extracting ariatoxins from prepress solvent-extracted cottonseed and peanut meals (16).…”

“…Data .from the laboratory extraction work (13,14) on acetone and water (90: 10), 2-propanol and water (80:20), and the azeotrope of 2-propanol and water (87.7:12.3), were used for larger scale extractions. The equipment used was a stainless steel basket type extractor, 20 cm square and 60 cm in length (15), equipped with an external spiral steam coil and insulation to provide and maintain heat. A 20-mesh screen near the bottom retained the meal, and the top was fitted with a cover to retard evaporation and cooling.…”

and Summary Solvent extraction of agricultural products has been suggested as an effective means of removing aflatoxins from mold‐damaged commodities. The use of various polar solvents such as the azeotrope of acetone‐hexane‐water and of 2‐propanol‐water, aqueous acetone, and aqueous ethanol has been reported in the literature. This paper examines the overall aspects of solvent extraction, in particular the use of the azeotrope of 2‐propanol‐water, to remove aflatoxins from prepress solvent extracted cottonseed meal.

“…Physical methods include separation by solvent extraction [2][3][4] and adsorption to solid toxin binders such as aluminosilicates, activated carbon and some special polymers [5]. Physical removal is also achieved by electromagnetic waves such as gamma rays [6,7], solar radiation, and microwave heating [8].…”

Degradation of aflatoxin B 1 in groundnut cake, a residue after oil extraction, by Rhodococcus erythropolis was optimized using response surface methodology. The bacterium was first grown in synthetic medium to determine optimal growth conditions using the combination of the Plackett-Burman and Box-Behnken methods and consequently aflatoxin B 1 in groundnut cake slurry was degraded under varying culture conditions. Optimal growth conditions were found as 22.5°C of temperature, pH 7, 100 mL of culture volume in 500 mL flasks, 1 % (v/v) of inoculum size, 135 rpm of agitation speed, 5 g/L of glucose and 5 g/L of peptone concentration according to analysis of the Box-Behnken design. Optimal detoxification conditions were found as 27.4 % (w/v) of solid concentration, 4.88 % (v/v) of inoculum size and 24 h of incubation time by Box-Behnken response surface optimization. Maximum detoxification level was predicted as 92.2 % by the constructed model while the experimental counterpart was 87.3 %. The suggested culture conditions have the potential to decrease aflatoxin B 1 from 200 lg/kg to below 20 lg/kg, the regulatory limit, in feed materials.

“…ACETONE is an excellent solvent for vegetable oil and has been used for the extraction of cottonseed oil in Italy for many years (Vaccarino, 1961). It has also been suggested for use in combination with hexane and water to extract gossypol (Gastrack et al, 1965) and aflatoxin (Gardner et al, 1968) from cottonseed. Acetone can be produced from vegetable resources by fermentation (Weizmann and Hamlyn, 1920) and ha's potential as an alternate to the petroleum-based hexane, if the continued availability and/or low cost of hexane becomes questionable (Hron et al, 1982).…”

Dclintered cottonseed was hulled and flaked. Moisture-adjusted cooked and uncooked samples were either dried or left undried, and all samples were then Soxhlet-extracted with acetone for five hours and desolvcntized. Sensory testing of gruels prepared from the meals indicated that if free moisture was not present during acetone extraction, catty odors were not found in extracted meals. Gas chromatographic analyses of acetone extracted meals showed concentrations of 0.3 ppm mesityl oxide and 0.7 ppm diacctonc alcohol, believed to bc catty odor precursors, in a catty-odorless meal, whereas concentrations of 1.6 ppm and 0.8 ppm, respectively, were found in a product with a catty odor.
