Mitigation of multiple pesticide residues in green bell pepper using natural extracts as an emerging trend in pesticide decontamination using GC–MS/MS Renuka Venkatachalapathy, Maria Jenita Peter, Lalitha Priya Udhyasooriyan, Sukumar Muthusamy Journal of Food Process Engineering, 2024 The main objective of this work is to assess the effect of natural extracts and its characterization for the mitigation of multiple pesticide residues in green bell pepper. In this study, four plant extracts such as Acacia concinna, Albizia amara, Tamarindus indica, and Azadirachta indica have been used to mitigate the six pesticides present in green bell pepper and its phytochemical constituents were analyzed using gas chromatography coupled to triple quadrupole tandem mass spectrometry (GC–MS/MS). In addition to that, the method for the quantification of six pesticide residues in green bell pepper using GC–MS/MS was validated according to SANTE/11312/2021 guidelines. The extracts of Acacia concinna, Albizia amara, Tamarindus indica, and Azadirachta indica were showed effective mitigation for selected pesticides. The phytochemical compounds present in plant extracts were correlated with its effect on the mitigation of multiple pesticide residues. The T. indica showed better pesticide mitigation efficiency when compared to A. indica, A. amara, and A. concinna, respectively. The plant extracts showed higher mitigation efficiency for organophosphorous pesticides than the synthetic pyrethroids. The nutritional and sensorial properties of green bell pepper were highly retained after pesticide decontamination using plant extracts. The results of this work indicated the application of plant extracts for the mitigation of multiple pesticides in green bell pepper by household and commercial processing units. This study addressed the balance between food safety and food quality.Practical ApplicationsPesticide contamination in vegetables is one of the major global food safety issues and it poses potent threat to human health. Pesticide decontamination is always a challenging task due to the unpredictability of types and levels of pesticides and the presences of multiple pesticides in contaminated vegetables. Washing of vegetables with water is the common procedure followed by both household and commercial units. However, washing of vegetables only with water is not enough to reduce the multiple pesticides residues to safe levels. The washing of vegetables with chemical solutions and other thermal and non‐thermal processing could result in toxic byproduct formation based on the types of pesticides present in contaminated sample. Hence, in this study, the plant extracts were characterized for its efficiency on the mitigation of multiple pesticide residues in vegetables has been analyzed by Gas Chromatography—Triple Quadrupole Tandem Mass Spectrometry and the method has been validated according to SANTE/11312/2021 guidelines. The phytochemical compounds of the plant extracts could be correlated with the effective multiple pesticide decontamination efficiency and the plant extracts were found to retain the physicochemical properties of vegetables during washing. The results of this study showed that the selected plant extracts could enhance the food safety without compromising food quality. The results of this study could be useful for the formulation of vegetables cleaning solutions for the effective mitigation of multiple pesticide residues.
Development of bacterial inactivation model and evaluation of shelf life extension of Littopenaeus vannamei using blue LED illumination Lalithapriya Udayasoorian, Mariajenita Peter, Renuka Venkatachalapathy, Palpandi Raja Ramachandran, Sukumar Muthusamy Journal of Food Process Engineering, 2023 Pacific white shrimps pre‐inoculated with bacterial culture were subjected to blue LED illumination at 4°C and 15°C. Mathematical modeling of bacterial inactivation from 0 to 48 h of illumination revealed that Hom and Weibull model represent the best fit. Shelf life analysis of shrimps illuminated with 1075.68 J/cm2 (I1), 2151.36 J/cm2 (I2), 3227.04 J/cm2 (I3), 4302.72 J/cm2 (I4) dosages at 4°C revealed that reduced counts for pH, trimethylamine, hypoxanthine, total plate count, psychrotrophic bacterial count and weight loss % were observed in I4 samples, whereas TBARS, color and texture were retained better in I1 and I2 samples. Bioelectrical impedance analysis (BIA) revealed that lower internal component change percentage of 7.35 and 14.85 was observed in I1 and I2 samples. Microscopic examination of shrimp muscle disclosed increased disintegration of myofibrillar structures in I4 and I3 samples. Illumination dosage ≤2200 J/cm2 extended the shrimp shelf life to 45 days at 4°C and 15 days at 15°C without changing the quality.Practical ApplicationThe demand for quality seafood products and concern for the safety aspects leads to the development of innovative preservation method. The impact of blue LED illumination on L. vannamei shrimps depicted significant increase shelf‐life and retention of quality parameters. Inactivation kinetics of LED illumination on shrimps depicted that Weibull and HOM model resulted best fit based on the R2 and AIC values helps in process scale‐up and operation at industrial level. Successful implementation of these illumination system as a processing equipment or in cold supply chain transport vessels will help the exporters to reduce the losses and conventional processing cost. It can also be employed in portable refrigerators, freezer boxes, storage shelves and ware houses with slight modifications in designs aspects to extend the shelflife of the seafood without losing its organoleptic properties. Further, it aids in effective export performance and extended distribution of shrimps in domestic market.
Characterization of an effective drug carrier system for improved oxidative and thermal stability of essential fatty acids: a review Maria Jenita Peter, Udayasoorian Lalithapriya, Renuka Venkatachalapathy, Muthusamy Sukumar International Journal of Food Properties, 2022 Essential fatty acids play an important role in promoting brain development, decreasing the incidence of cardiovascular diseases, and reducing inflammation. However, they are inherently unstable and susceptible to oxidative deterioration due to two or more double bonds in their structure. Delivery systems have been developed to provide effective encapsulation and protection for sensitive fatty acids, thus fulfilling their health benefits. Emulsion-based microencapsulation is one of the most promising techniques for the delivery of omega 3 & 6 fatty acids. The emulsion composition and structure, as well as the storage conditions are regarded as key factors to influence the shelf life and stability of emulsions. To maximize the resistance of these fatty acids in emulsions against oxidation, emulsion structure design was particularly highlighted, and different methods for tailoring emulsion structure were developed. The current work was focused on the careful design of emulsion structure to improve the oxidative stability and shelf life of fatty acids (FAs). Different types of carrier systems, formulations, including conventional emulsions, multilayer emulsions, gelled emulsions, pickering emulsions, and structures designs are discussed, and their protective effect for FAs are with regard to food fortification is also conferred, particularly the role of interfacial structure in emulsions is emphasized. The effects of emulsifiers and its modification methods on the interfacial structure are presented to improve further the stability of FAs during storage.
Removal of pesticides from strawberries using plant extracts and assessed by gas chromatography-triple quadrupole mass spectrometry Venkatachalapathy Renuka, Anoop Chandra Indira Ramachandran, PackirisamyAzhagu Saravana Babu, Somnath Das, Maria Jenita Peter, Lalitha Priya Udhyasooriyan, Karthikeyan Senthilnathan, Muthusamy Sukumar International Journal of Environmental Analytical Chemistry, 2022 The extensive application of pesticides on fruits and vegetables during cultivation leads to potential risk to the environment and human health. The pesticide decontamination in fruits and vegetables is an essential step in food safety. In this study, the extracts of Tamarindus indica (TIE) and Azadirachta indica (AIE) were investigated for its effect on the removal of synthetic pyrethroids and organophosphate pesticides in strawberries. The pesticide removal was done by washing the contaminated strawberries with TIE and AIE at various concentrations (2%, 4%, 6% and 8%) with three different soaking times (5, 10 and 15 min). The pesticide residues in strawberries were quantified by the modified QuEChERS extraction method followed by gas chromatography with triple quadrupole mass spectrometry (GC-MS/MS). The method validation for determination of five pesticide residues in strawberry has been done in accordance with European Union guidelines. In method validation, the recovery values obtained for three fortification levels were found to be 75% to 95%. The analytical results showed that the higher removal level was obtained for malathion (67%) followed by dimethoate (66%), cypermethrin (64%), chlorpyrifos (64%) and deltamethrin (62%) during washing with 6% TIE for 15 min. The nutritional properties of strawberries were not significantly changed during washing with TIE and AIE. The current study showed the potential application of plant extracts for the removal of pesticides from fruits that leads to consumer protection from the health risk of pesticides by reducing its dietary exposure.
Effective removal of organophosphorus pesticide residues in tomatoes using natural extracts Renuka Venkatachalapathy, Indira Ramachandran Anoop Chandra, Somnath Das, Basheer Vajiha Aafrin, Udhyasooriyan Lalitha Priya, Maria Jenita Peter, Senthilnathan Karthikeyan, Muthusamy Sukumar Journal of Food Process Engineering, 2020 The reduction efficiency of the extracts of Albizia amara and Acacia concinna against most widely used organophosphorus pesticides such as dimethoate, malathion, dichlorvos, and chlorpyrifos on tomato samples was investigated. The pesticide residues were quantified by gas chromatography with triple quadrupole mass spectrometer (GC‐MS/MS). The maximum reduction efficiency was achieved from the samples treated with 8% A. concinna extract on dichlorvos (87%) and dimethoate (84%) followed by 6% A. amara on malathion (83%) and chlorpyrifos (64%) and comparatively higher than water wash and it shows the reduction of only 14–38% for 15 min. The sensorial property and lycopene content of tomato samples were assessed and these plant extracts showed no significant effects on color, texture, and lycopene content after washing treatment. These phytochemical rich plant extracts exhibited greater reduction ability against pesticide residues without changing the nutritional and sensorial characteristics of the treated tomato samples. The current study may be a platform for formulating a cost‐effective, safe, and natural cleanser for the effective removal of pesticide residues in fruits and vegetables. PRACTICAL APPLICATIONS: Presence of multiple pesticide residues in fruits and vegetables is a worldwide problem in food safety. Particularly, tomatoes are most often consumed without cooking, hence it is essential to estimate the pesticide reduction efficiency of the common washing procedure. Washing of tomatoes with chemical solutions to remove pesticide residues leads to additional chemical exposure. Therefore, the reduction efficiency of natural plant extracts such as Albizia amara and Acacia concinna on four pesticides (dimethoate, malathion, dichlorvos, and chlorpyrifos) was studied. The method for the analysis of pesticide using GC‐MS/MS was validated according to SANTE 11813/2017 to detect the pesticide residues in tomatoes after each washing treatment. This study showed that the natural extracts could be a good tool for the removal of multipesticide residues effectively from the tomatoes without compromising its nutritional and sensory properties. The pesticide decontamination with plant extracts was effective, economic and safe for household and commercial applications.
Investigation of Natural Extracts and Sodium Bisulfite Impact on Thermal Signals and Physicochemical Compositions of Litopenaeus vannamei during Chilled Storage Udayasoorian Lalithapriya, Peter Mariajenita, V. Renuka, Kasirajan Sudharsan, S. Karthikeyan, Meenakshisundaram Sivarajan, D. Murugan, Muthusamy Sukumar Journal of Aquatic Food Product Technology, 2019 This research work evaluates the impact of 1.2% pomegranate peel extract (Pp) (Punica granatum), 0.1% grapefruit seed (Gfs) (Citrus paradisi) extract, and synthetic preservative 1.25% sodium bisulfite on shelf life extension of Litopenaeus vannamei stored at 4 and 15°C. The application of isothermal titration calorimetry (ITC) for comparison of the extracts and chemical preservative on shrimp quality retention based on the overall heat production by microbial and enzymatic degradation was addressed. The occurrence of probable bioactive responsible for antimicrobial and antioxidant activity components in the extracts was examined through gas chromatography-mass spectrometry (GCMS). At 4°C, Pp-treated shrimps resulted in 6.73 logCFU/g, 6.93 logCFU/g, 5.31 mgN/100 g, and 0.58 mgMDA/kg for aerobic plate count, psychrotrophic bacterial count, trimethylamine, and thiobarbituric-acid reactive substance, respectively, on the 15th day. At 15°C, Pp-coated shrimps retained quality until day 4. Isothermal calorimetric analysis resulted in a rapid and sharp peak for fresh samples, whereas there was broad and delayed peak for shrimp treated with Pp and sodium bisulfite. These observations prove that Pp counterpart the chemical preservative and outperform Gfs on shrimp quality retention. Results also indicate that isothermal calorimetry can be a useful technique for shelf life predictions and comparative evaluation of extract impact on shrimp quality retention.
