Plant Bioactive Compounds in Pre- and Postharvest Management for Aflatoxins Reduction

et al. 2020

Aflatoxins (AFs) are secondary metabolites produced by Aspergillus spp., known for their hepatotoxic, carcinogenic, and mutagenic activity in humans and animals. AF contamination of staple food commodities is a global concern due to their toxicity and the economic losses they cause. Different strategies have been applied to reduce fungal contamination and AF production. Among them, the use of natural, plant-derived compounds is emerging as a promising strategy to be applied to control both Aspergillus spoilage and AF contamination in food and feed commodities in an integrated pre-and postharvest management. In particular, phenols, aldehydes, and terpenes extracted from medicinal plants, spices, or fruits have been studied in depth. They can be easily extracted, they are generally recognized as safe (GRAS), and they are foodgrade and act through a wide variety of mechanisms. This review investigated the main compounds with antifungal and anti-aflatoxigenic activity, also elucidating their physiological role and the different modes of action and synergies. Plant bioactive compounds are shown to be effective in modulating Aspergillus spp. contamination and AF production both in vitro and in vivo. Therefore, their application in pre-and postharvest management could represent an important tool to control aflatoxigenic fungi and to reduce AF contamination.

“…They originate from bacterial, fungal, plant, and marine animal sources [ 1 ]. They have a wide variety of applications in different sectors such as food, agricultural [ 2 ], pharmaceutical [ 3 ], packaging [ 4 ] application and cosmetics [ 5 ] and are often used as flavorings, beverages, repellents, fragrances as well as for their medicinal purposes [ 6 ]. Isolated natural products as pure compounds, plant extracts or essential oils have all been used for various applications over the years.…”

Nanosystems for the Encapsulation of Natural Products: The Case of Chitosan Biopolymer as a Matrix

et al. 2020

View full text Add to dashboard Cite

Chitosan is a cationic natural polysaccharide, which has emerged as an increasingly interesting biomaterialover the past few years. It constitutes a novel perspective in drug delivery systems and nanocarriers’ formulations due to its beneficial properties, including biocompatibility, biodegradability and low toxicity. The potentiality of chemical or enzymatic modifications of the biopolymer, as well as its complementary use with other polymers, further attract the scientific community, offering improved and combined properties in the final materials. As a result, chitosan has been extensively used as a matrix for the encapsulation of several valuable compounds. In this review article, the advantageous character of chitosan as a matrix for nanosystemsis presented, focusing on the encapsulation of natural products. A five-year literature review is attempted covering the use of chitosan and modified chitosan as matrices and coatings for the encapsulation of natural extracts, essential oils or pure naturally occurring bioactive compounds are discussed.

“…The average encapsulation efficiency of 60% was obtained under the optimized conditions and concentration (polymer solution with 1% w/v pectin, cross-linker with 0.5 w/v CaCl2). Since, the encapsulation improves the stability of an essential oil 39 , the obtained value of EE represents an attracting value from the industrial point of view. High encapsulation efficiencies of 87.6-90.6% for sunflower oil encapsulated by ionic gelation using pectin have been previously reported 40 .…”

The use pesticide is one of the indispensable means to combat mosquito borne diseases. However, the repeated use of synthetic pesticides has induced resistance in the vector pest along with undesirable impact on the environment. The biodegradability, non-persistent and user's safety are the root cause to prefer plant-derived pesticides to synthetic ones. The botanical based pesticides tend to degrade rapidly under the influence of several environmental factors. For the feasible application as pesticides, the plant products are formulated either as liquid or as purely solid. Despite well-established formulation technology in pesticide delivery, their handling trouble is being ignored. There is difficulty in liquid formulation of pesticide products, as they are prone to splashing and spillage, resulting in contamination, wastage and direct exposure to skin; whereas a solid formulation tends to produce dust. In the present work, cedarwood (Cedrus deodara) essential oil embedded pectin nanocapsules were produced. The nanocapsules were characterized according to their morphology, size, encapsulation efficiency and thermal stability. Furthermore, the nanocapsules were impregnated onto mini cotton tea bags to be employed as RTU (ready to use) formulation for treating the breeding sites of mosquitoes. The larvicidal activity of the bags treated with pectin-cedar wood nanocapsules was assessed against malaria vector, Anopheles culicifacies and 98% mortality was recorded till 4 weeks, this suggests its potential and hassle free applications in controlling mosquito vector. Global health threats, primarily due to mosquito borne diseases can devastate communities in social and economic terms and hinder development progress 1. Among the various vector borne diseases, malaria is the major public health issue, which transmits through the bite of Anopheles mosquitoes 2. According to the World Health Organization (WHO) 2019 report, malaria causes 228 million morbidity cases and 405,000 number of mortality 3. Anopheles culicifacies is alone accountable for 60-65% of the malaria burden 4. A Mosquito-borne disease remains a challenge since there is no vaccine, and further drug resistance is an increasing threat. Under these circumstances, vector control plays a vital role and often remains the only way to prevent disease outbreaks. The control of malaria vector, Anopheles, relies upon indoor residual spray (IRS) and insecticide treated nets (ITN) 5. Several other control tools have also been proposed including; nano pesticides, microbial pesticides (that are natural occurring bacteria, fungi and viruses) and pesticides of plant origin, which may act as repellents, oviposition deterrents and larvicides etc. 6,7. A new generation biotechnological tool in mosquito control program, based on genetically modified mosquitoes and sterile Insect Technique (SIT) is also being considered 7,8. Despite significant progress so far, further investigations are needed to determine if genetically modification based strategies can be an effective metho...
