Method: Cold trap enrichment-GC/MS technology was used to determine the component. Result: The detection results showed that the levels of odorant concentrations from the main processing units were ranked in the order of: temperature sterilization device > oil-water separator > anaerobic fermenter > separation equipment > unloading area. Oxygenated organic compounds were the main components. Conclusion: Ethanol, hydrogen sulfide, dimethyl disulfide, ammonia, limonene were characteristic pollutants in the unloading areas and separation equipment;ethanol, methyl mercaptan, hydrogen sulfide, dimethyl disulfide, limonene were characteristic pollutants in the temperature sterilization device and oil-water separator;ethanol, hydrogen sulfide, dimethyl disulfide, p-diethylbenzene, limonene were characteristic pollutants in the anaerobic fermenter.展开更多

The comparison results between XRD, SEM, and EDS analyses of MAPs in the dried compost and synthesized MAPs confirm the formation of MAP crystals in the simulated food waste aerobic composting process. The analysis of the compost also indicates that the addition of all the three mixtures of Mg and P salts in the aerobic composting process can increase nitrogen conservation and decrease nitrogen loss because of the formation of MAPs. The mechanism of MAP formation was verified as the reaction of ammonium（NH4＋） with magnesium（Mg^2＋） and phosphate[HnPO4^（3-n） , n=0, 1, and 2）.展开更多

Dispersion of aqueous extracts of intact seed oil bodies (OBs) in water is a novel and interesting way of producing natural and oxidatively stable food emulsions with minimal use of synthetic antioxidants and emulsifiers. As there is growing interest in natural food emulsions containing unsaturated oils, we investigated whether the oxidative stability of canola OB emulsions could be further improved by subjecting canola seed to heat-treatment prior to oil body extraction. Oil-in-water (5%, w/w) emulsions of OBs extracted from canola seed before and after heat-treatment were considerably more resistant to oxidation than emulsions prepared from refined canola oil and Tween? 40 emulsifier. However, only small amounts (0.9% - 4.5% by weight) of the phenolic compounds present in canola seed were transferred to the OBs after aqueous extraction, and consequently there was no discernible effect on oxidative stability as a result of prior heat-treatment of the seed. Thus, in contrast to oil, there is no oxidative stability benefit to be gained by subjecting canola seed to heat-treatment prior to extraction of OBs.展开更多
