“…These techniques include chromatographic, immunochemical, and spectroscopic methods. Further these methods can be categorized into chemical analysis, biological identification, instrumental analysis, and immunoassays (Yan et al, 2020). Moreover, there are factors to be considered when selecting the quantifying method of aflatoxins such as specificity, sensitivity, reliability, and simplicity (Mahfuz et al, 2018).…”

“…The countries like ours have a high degree of aflatoxin exposure due to limited access to sophisticated analytical methods. The Association of Official Analytical Chemists (AOAC) and the European Committee for Standardization (ECS) have published nearly 50 different aflatoxin detection methods for food commodities (Yan et al, 2020). Nevertheless, to ensure the safeness of food and minimize aflatoxin-related sicknesses, the detection methods are required to be specific, sensitive, and also affordable.…”

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

2023

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.

“…In recent years, scientists and researchers from various countries have proposed many detection methods for AFB 1 in food [ 7 , 8 , 9 ]. In China, “Limits of Mycotoxins in Foods” (i.e., GB 2761-2017) stipulates that the limit value of AFB 1 in peanut oil and corn oil is 20 μg/kg, and the limit value of AFB 1 in other vegetable oils and fats is 10 μg/kg [ 10 ].…”

This study proposes a label-free rapid detection method for aflatoxin B1 (AFB1) in pressing peanut oil based on Raman spectroscopy technology combined with appropriate chemometric methods. A DXR laser Raman spectrometer was used to acquire the Raman spectra of the pressed peanut oil samples, and the obtained spectra were preprocessed by wavelet transform (WT) combined with adaptive iteratively reweighted penalized least squares (airPLS). The competitive adaptive reweighted sampling (CARS) method was used to optimize the characteristic bands of the Raman spectra pretreated by the WT + airPLS, and a partial least squares (PLS) detection model for the AFB1 content was established based on the features optimized. The results obtained showed that the root mean square error of prediction (RMSEP) and determination coefficient of prediction (RP2) of the optimal CARS-PLS model in the prediction set were 22.6 µg/kg and 0.99, respectively. The results demonstrate that the Raman spectroscopy combined with appropriate chemometrics can be used to quickly detect the safety of edible oil with high precision. The overall results can provide a technical basis and method reference for the design and development of the portable Raman spectroscopy system for the quality and safety detection of edible oil storage, and also provide a green tool for fast on-site analysis for regulatory authorities of edible oil and production enterprises of edible oil.

“…Using gold nanoparticles-antibody label, contamination of conjugate harmful aflatoxins causing impaired growth can be significantly reduced. Packaging with silver nanoparticles aluminium foils can be useful as it eventually becomes biofilms which allow conservation of the quality of spices, and they can be conserved and served to consumers with the same quality as they have at harvesting [1].…”

Horticulture is a branch of Agricultural science where it is defined as the science and art of cultivating and handling fruits, vegetables, ornamental plants and several plants having unique medicinal and aromatic values. Horticultural crops provide farmers with high income and have good export quality, but they have a concern about postharvest losses. Hence, increasing productivity and decreasing post-harvest losses by using scientific studies and techniques like biotechnology and nanotechnology could be the simplest possible solution to the above-mentioned problems. Using nanotechnology which is having the characteristics of nanoparticles is proven to be very useful in science and technological applications. Nanotechnology-based formulations increase the product quality and the shelf life of horticultural products and provide multiple ways of inhibiting the growth and development of microorganisms. It is precisely a new edible packaging coverage (film) that controls the exchange of gases and prevents damage from harmful rays such as ultraviolet radiation to a greater extent. Increasing strength by using nano biosensors for labeling products is considered a fundamental process to automated control of storage products. Postharvest rotting of vegetables is recognized to be an oxidative reaction and microbial deterioration as well. This review will address all such nanotechnology-based advancements for minimizing post-harvest losses of horticultural crops and enhancing the socio-economical progress of growers in particular.
