Esameldin Bashir Mohamed Kabbashi, Salah Eldeen Abbas Ali, Nawal Abdelgayoum Abdelrahman.

The Aflatoxins are fungal toxins and products of Aspergillus flavus and A. niger. They include B aflatoxins (B1, the most potent hepatocarcinogen known, and B2) which are produced by both species and aflatoxins G (G1 and G2) that are produced by A. niger and aflatoxin M1 and Q1 metabolites of B1 and aflatoxin M2 metabolite of Aflatoxin B2. Since the discovery of aflatoxins in 1960, after an outbreak of a disease of unknown etiology of turkey in England, the scientific approach towards these toxins concentrated on the protective measures and control of the incidence of these carcinogens either.
Objective: This study aimed at coming out with a remedy and curing for elimination of aflatoxin B1 in peanut paste. The importance of this stemmed from the fact that aflatoxin occurrence is rather inevitable considering all the advancements in the protective measures.
Methods: However, since the incidence of these toxins is rather unavoidable countable attempts were done on the treatment of these toxins in food and feed stuffs. Accordingly this fact persuaded testing some easy and familiar culinary approaches to mitigate and/ or perhaps diminish the presence of aflatoxin B1 (AFLB1) in the commonly consumed peanut (Arachis hypogaea L.) paste. Lime juice, in two doses (12.5 and 25 ml/ g), was applied to 25 g peanut paste contained AFLB1 (7.53 ppb) and stored for 1, 3 and 7 days. The test material was then analyzed for AFLB1 using aflatest® HPLC column of Vicam® of Waters corporation and HPLC Shimatzu® brand.
Results: The collected data of the test samples reflected a reduction in AFLB1, due to the doses of 12.5 and 25 ml lime juice, of 11% and 31%, respectively (for one day storage), 54% and 66%, respectively (for 3 days storage), and 74% and 92% (for 7 days storage). Conclusions: These results are encouraging for use of lime juice as a treatment for aflatoxin B1 wherever applicable.

Key words: Aflatoxin B1, Lime Juice, Peanut Paste, Treatment.
