“…Better maintenance of phenolic compounds and vitamin C and delayed browning and oxidation on fresh-cut apples treated by PL only support this claim. Similar results can be found in the study [ 54 ].…”

Mycotoxins cause adverse effects on human health. Therefore, it is of the utmost importance to confront them, particularly in agriculture and food systems. Non-thermal plasma, electron beam radiation, and pulsed light are possible novel non-thermal technologies offering promising results in degrading mycotoxins with potential for practical applications. In this paper, the available publications are reviewed—some of them report efficiency of more than 90%, sometimes almost 100%. The mechanisms of action, advantages, efficacy, limitations, and undesirable effects are reviewed and discussed. The first foretastes of plasma and electron beam application in the industry are in the developing stages, while pulsed light has not been employed in large-scale application yet.

“…In another study [ 54 ], a pilot-scale PL applicator was used to treat 5 mL samples of a peanut oil of 10 mm thick. Results showed 48, 56, and 78% aflatoxin reduction for 400, 600, and 800 s exposure times, respectively.…”

“…However, there is a limitation in using this method due to the high temperature generated during the irradiation. The results showed that the oil's temperature increased from 26°C to 220°C during the 10-min temperature-controlled pulsed light treatment [29]. The high temperature reduced the oil quality by elevating the peroxide value, acid value and percentage of free fatty acid in the oil after 400 s irradiation.…”

This study aimed to evaluate the quality of aflatoxin B1-detoxified unrefined groundnut oils. Detoxification of aflatoxin B1 (AFB1) in unrefined groundnut oils was performed by ultraviolet light-emitting diodes (UV-LED) irradiation. Ten samples of unrefined groundnut oils were subjected to UV-LED treatment before the measurements of AFB1 content, fatty acid compositions and chemical properties. The 20-min treatment reduced AFB1 content by 99%. Both acid and peroxide values of the oil samples showed little changes after the samples were treated with UV-LED irradiation. GC-MS results showed that 21 types of fatty acid were detected in the untreated oil samples. Minor changes in the levels of fatty acid were also observed after the 20-min treatment. The results proved that UV-LED irradiation effectively reduced AFB1 content in the unrefined groundnut oils and maintained the oil quality. It is a promising strategy for detoxification of AFB1 in groundnut oil.

Both a*(rednessgreenness) and b* (yellowness-blueness) values increased with time while the L* (lightness) value did not seem to be influenced by the treatments (Abuagela et al, 2018). Therefore, the application of pulsed light can be recommended as a propitious technology to detoxify aflatoxincontaminated edible oils on a mass scale.…”

Aflatoxin Occurrence, Contamination, Detection, and Decontamination with Special Emphasis on Coconut Oil: A Review

2023

View full text Add to dashboard Cite

Purpose: Coconut oil is one of the commonest and profusely used plant oils in Asian cuisine. Many studies are being carried out aiming at preventing/eliminating potential aflatoxin contamination of the oil or its products along the value chain. The present review analytically provides an overview of aflatoxin occurrence, contamination, detection, and decontamination of vegetable oils with special emphasis on coconut oil.Research Method: Findings and conclusions of studies related to aflatoxins, that are published in authentic sources were reviewed and presented in a chronological manner. Based on the information, current detection and decontamination methods for aflatoxins in edible plant oils were demonstrated.Findings: Complete decontamination of aflatoxins from edible oils seemed impossible, but reducing the accumulated concentrations below the permissible levels seemed possible. The use of chemical agents like alkalis, the most commonly practiced method on a commercial scale, adversely affects human health and the environment. UV irradiation is a promising physical decontamination method of oil with aflatoxins and combining UV irradiation with other potential methods such as the use of adsorbents showed an enhanced efficacy. However, further studies are required to ensure the effective and safe use of biological methods in aflatoxin-contaminated edible oils. Research Limitations:Research gaps in the application of biological decontamination methods in edible oils especially in coconut oil were found.Originality/ Value: This paper critically and aimfully analyzes the relevant information with a view to find gaps thereby showing new directions for applied research to assess nutritional, sensory, and quality attributes in the oils and value-added products, subjected to biological treatments.
