Oil portion of Tenebrio molitor (yellow mealworm) and Acheta domesticus (house cricket) were examined and it was investigated how the physicochemical properties of the oils changed with High Hydrostatic Pressure Assisted Extraction (HHP-E) and conventional solvent extraction (CE) with hexane. The effect of HHP-E at 500 MPa and 30 and 40 degrees C for 15 min on the properties of oils was compared with the CE. Following the extraction of oil, fatty acid composition, peroxide value, crystallization and melting points, total phenolic content and antioxidant activities were determined. Oil yield was found in the range of 22.75-24.22% for mealworm and 16.17-18.09% for cricket with significant amount of Omega-3 and Omega-6 fatty acids. Fatty acid composition of insect oils was significantly affected from HHP-E and extraction temperature (p < 0.05). The difference between crystallization and melting point of mealworm were found to be higher than cricket (p < 0.05). HHP-E insect oil had desirable characteristics to be used as a food ingredient.

Detoxification of Groundnut Cake Naturally Contaminated with Aflatoxin B-1 Using Rhodococcus erythropolis in Shake Flask Bioreactors Dogan, Onay Burak; ÖNAL ULUSOY, BARAN; Bozoglu, Faruk; Sagdicoglu-Celep, Adviye Gulcin; Çekmecelioğlu, Deniz (Springer Science and Business Media LLC, 2017-04-01) 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 A degrees C of temperature, pH 7, 100 mL of cult...
Effect of pH, flow rate and concentration on the sorption of Pb and Cd on montmorillonite: I. Experimental Altin, O; Ozbelge, OH; Doğu, Timur (Wiley, 1999-12-01) Continuous column adsorption of lead (Pb) and cadmium (Cd) was studied using pH adjustment and calcium-saturated montmorillonite in a short stainless steel column. Changing either pH or flow rate, while keeping inlet concentration of the ions constant, led to considerable changes in effluent concentrations and breakthrough curves (BTCs). At low pH values (2-4), H+ ions competed strongly with lead and cadmium ions; at intermediate pH (4-6), ionic size played the major role in adsorption and ion exchange and ...
Effects of minerals on steam distillation during thermal heavy-oil recovery: An experimental investigation Osgouei, Yashar Tavakkoli; Parlaktuna, Mahmut (Informa UK Limited, 2018-01-01) An experimental study was carried out to investigate the role of various clay and non-clay minerals present in reservoir formations on steam distillation process. Dead oil samples (100 g) of two heavy oil reservoirs with 30 g of water and 10 g of crushed rock mixed with different clay minerals were kept under steam pressure with 150, 200, and 250 degrees C in a batch autoclave reactor for a period of 40 hours, and the results were compared with respect to the changes in the density, viscosity and chemical c...
KINETICS OF WINE SPOILAGE BY ACETIC-ACID BACTERIA KOSEBALABAN, F; OZILGEN, M (Wiley, 1992-01-01) Acid production in wines inoculated with acetic acid bacteria from vinegar was studied at 15-degrees-C, 20-degrees-C, 25-degrees-C and 30-degrees-C and simulated with kinetic models. Results indicated that major wine spoilage did not occur during the growth of the microorganisms, but during their extended presence at high concentrations during the stationary and death phases. Acetophilic species were observed to resist death, which is in agreement with the mechanism suggested by Kittelmann et al.9 for the d...
Effects of nickel, chromium and initial feed concentration on the batch growth of a microbial consortium developed from sewage Gökçay, CELAL FERDİ; Dilek, Filiz Bengü (Informa UK Limited, 1991-01-01) Effects of nickel, chromium and substrate concentration on the microbial growth of acclimatized and unacclimatized microbes of sewage origin were studied in batch cultures at a constant temperature of 25 °C, at pH 7.0. A synthetic medium supplemented with Ni(II) (5 and 10 mgl‐1) or Cr(VI) (1 and 50 mgl‐1) or with their combinations and at various feed concentrations (650, 975, 1300 mgl‐1) was employed to investigate the effects on the specific growth rate (μm) of the microbial culture. The experimental resu...
