Effects of γ-irradiation (1.0-10 kGy) on trypsin, chymotrypsin, and R-amylase inhibitors of soybean and Moringa peregrina seeds on tannin of sorghum, gossypol of cottonseed, and in vitro digestibility of soybean were investigated. A dose of 10.0 kGy caused decreases in trypsin (by 34.9%) and chymotrypsin (by 71.4%) inhibitor activities in soybean defatted flour, whereas its in vitro digestibility increased from 79.8 to 84.2%. The R-amylase inhibitor activity of Al-Yassar (M. peregrina) was decreased by 43.6 and 47.8% upon treatment of 7.0 and 10.0 kGy, respectively. Doses of 10.0 and 7.0 kGy significantly reduced the tannin content in Shahlla sorghum but not in Hemaira sorghum. Total and free gossypol contents were slightly reduced by irradiation.

“…Consequently glandless cottonseed accounts for less than 0.5% of the total crop in the world. A number of methods have been developed for removing gossypol from cottonseed including solvent extraction of free gossypol (Damaty and Hudson, 1975;Canella and Sodini, 1977;Cherry and Gray, 1981;Rahma and Narasingo Rao, 1984), ferrous sulfate treatment (Tabatabai et al, 2002;Barraza et al, 1991), calcium hydroxide treatment (Nagalakshmi et al, 2002;2003), microbial fermentation (Wu and Chen, 1989;Shi et al, 1998) and so on. These methods play an important role in detoxification of CSM, but the reduction of gossypol using solvent system suffers from the difficulty of totally removing residual solvents which have potentially harmful effects, as adversely affect the flavor.…”

Abstract:The objective of this work was to investigate the effect of six individual strains of fungi on the reduction of gossypol levels and nutritional value during solid substrate fermentation of cottonseed meal (CSM). Six groups of disinfected CSM substrate were incubated for 48 h after inoculation with either of the fungi C. capsuligena ZD-1, C. tropicalis ZD-3, S. cerevisae ZD-5, A. terricola ZD-6, A. oryzae ZD-7, or A. niger ZD-8. One not inoculated group (substrate) was used as a control. Levels of initial and final free gossypol (FG), crude protein (CP), amino acids (AA) and in vitro digestibility were assayed. The experiment was done in triplicate.The experimental results indicated that microbial fermentation could greatly decrease (P<0.05) FG levels in CSM. The detoxification efficiency differed between the species of microorganisms applied. From the perspective of reducing CSM potential toxicity, C. tropicalis ZD-3 was most successful followed by S. cerevisae ZD-5 and A. niger ZD-8. They could reduce FG levels of CSM to 29.8, 63.07 and 81.50 mg/kg based on DM (dry matter), respectively, and their detoxification rates were 94.57%, 88.51% and 85.16%, respectively. If crude protein, amino acids content and their in vitro digestibility were also taken into account, A. niger ZD-8 may be the best choice. The CP content of CSM substrate fermented by C. tropicalis ZD-3 and A. niger ZD-8 were improved by 10.76% and 22.24%; the TAA (total amino acids) contents were increased by 7.06% and 11.46%, and the EAA (essential amino acids) were raised by 7.77% and 12.64%, respectively. Especially, the levels of methionine, lysine and threonine were improved greatly (P<0.05). The in vitro CP digestibility of CSM fermented by C. tropicalis ZD-3 and A. niger ZD-8 was improved by 13.42% and 18.22%, the TAA were increased by 17.75% and 22.88%, and the EAA by 16.61% and 21.01%, respectively. In addition, the in vitro digestibility of methionine, lysine and threonine was also improved greatly (P<0.05).

“…The detoxification of gossypol is done by physical, chemical or biological treatments such as solvent extraction of oil during trituration, supplementation with amino acids or vitamins and plant improvement work to obtain "glandless" varieties (Diaw et al, 2011). In oil mills, solvent extraction of cottonseeds oils is commonly used (Damaty and Hudson, 1975;Canella and Sodini, 1977;Cherry and Gray, 1981;Rahma and Rao, 1984) and can be grades ranging from 0.03 to 0.14% free gossypol and 1.09 to 1.16% bound gossypol (Proctor et al, 1968;Vix et al, 1971;Yu et al, 1993). Thus, gossypol can be removed from the oil by solvent extraction after extraction of the oil from the seeds, either mechanically or with solvents (Brink and Achigan-Dako, 2012).…”

Edible oils are widely consumed foods. These oils come from various animal materials raw and vegetable products. Edible oils are prone to many contaminants. Contaminants can be found at all levels from oilseed production to conservation through refining processes and end up in oils. The contaminants origin may be of endogenous or exogenous. These are water, phosphorus, non-visible insoluble compounds, free fatty acids, residual hexane, benzo [a] pyrene, pesticides, dioxins, mycotoxins, mineral oils, cargo residues, minerals such as iron, copper, lead, gossypol, many primary and secondary oxidation products, etc. To eliminate or limit these compounds having a nuisance or toxicity for the consumer, it is allowed the refining of oils (chemical, physical or enzymatic). In addition, the regulatory limits of anti-nutritional factors in edible oils have been set in order to obtain quality oils and to guarantee the health of consumer living in developing country. This results in analytical methods developed for quantitative and qualitative evaluation of oils intended for human consumption. Contribution/Originality: This study on the contaminants of edible oils contributes to knowledge the sanitary consumption of these oils and their analytical methods. Previously, the contaminants in the oils did not experience infatuation. Our study focuses on pesticides, mycotoxins and gossypol which are anti-nutritional factors present in edible oils widely consumed.
