Significance and Functions of Biosensors. Abstract The food industry has inappropriate techniques for process and quality control and requires techniques that can provide information on the physical and chemical properties of food quickly and affordably. Food applications mostly focus on the identification of contaminants, with a few significant analytes, such as sugars, alcohols, amino acids, flavors, and sweeteners, as exceptions. Biosensors can bring about an analytical revolution to address the problems facing the food and agriculture industries. Potential applications for biosensors inc ..read more

Bactericidal efficacy and mechanism. Abstract Here, the bactericidal efficacy and mechanism of action of the combination of alkaline electrolyzed water (AlEW) and acidic electrolyzed water (AcEW) on Pseudomonas aeruginosa biofilm were investigated, in comparison with single AcEW or AlEW treatment. The mature P. aeruginosa biofilm was formed at 120 h of cultivation. The number of bacteria in the P. aeruginosa biofilm decreased by 7.87 and 2.51 Lg CFU/mL after single AcEW and single AlEW treatment for 8 min, while the sterilization rate reached 92.2% and 33.1%, respectively. The group of AcEW ..read more

Heavy metals contaminated vegetables consumption and their risk assessment Abstract Human health is the biggest issue with consumption of contaminated vegetables and water. This study aimed to quantify heavy metals in soil, irrigation water, and vegetables in five urban and peri-urban area of Delhi. Under this study, vegetable crops, i.e. spinach, tomato, carrot, potato, onion and mustard were selected and soil, water and vegetable samples were analyzed for five toxic heavy metals, i.e. As, Cd, Cr, Hg, and Pb. Result showed that in irrigation water samples, Cd crossed the WHO/FAO permissible ..read more

This study presented evidence of the biofunctional and biosafety properties of goat milk proteins peptides. Abstract Goat milk and protein hydrolysate peptides have generated significant interest due to their diverse range of biological functions. To produce these peptides, casein (CP), and whey proteins (WP) were partially purified from goat milk and subsequently hydrolyzed with gastrointestinal endopeptidases such as pepsin, trypsin, and α-chymotrypsin based on in silico selection to achieve gastrointestinal stable peptides. The hydrolysates were characterized using various techniques, inc ..read more

This paper investigates how the rise in ambient temperature designed according to climate change affects the attachment levels of Escherichia coli O157:H7, O104:H4 and O26 on cress leaves. This study revealed that temperature increase designed according to climate change did not cause any significant change in persistence of pathogens studied here on leaf tissue. However, the bacterial load on the leaves was above infectious dose for humans and established pathogen load on cress leaves did not show any reduction with washing. Abstract Climate change and its worldwide effects are undeniable ..read more

Antimicrobial activity and mechanism of MLEO. Abstract As the interest in “natural” and “safe” products grows, the use of natural products instead of synthetic preservatives to combat food spoilage and poisoning caused by microorganisms during processing and storage has become a prioritized option. The present research evaluated the antibacterial activity of the Mentha longifolia L. essential oil (MLEO) against several pathogenic bacteria, and the mechanism of action against methicillin-resistant Staphylococcus aureus (MRSA). Gas Chromatography Quadrupole Time-of-Flight Mass Spectrometry (GC ..read more

This study uses probiotic Bifidobacterium breve as an active ingredient in an edible film. This paper provides information on the optimized concentration of sodium caseinate for the development of the probiotic-edible film. The desirable physicochemical properties, high viability, and antibacterial properties against three common food pathogens displayed by the sodium alginate-B. breve edible films may enable their future use as bioactive packaging for food products. Abstract The addition of probiotic bacteria creates added value to food products wrapped with edible film. Hence, this study a ..read more

This study demonstrated that the incorporation of air, carbon dioxide (CO2), and nitrogen (N2) ultrafine bubbles (UFB) in chlorine and peracetic acid antimicrobial (AM) solutions resulted in increased log reductions (0.4–1.5 logs) of fresh and aged Listeria monocytogenes biofilms on polypropylene (PP) and stainless steel (SS) surfaces, whereas incorporation of CO2 UFB in AM solutions resulted in ~1 log greater reductions of fresh and aged L. monocytogenes biofilms on silicone (S) surfaces compared with AM solutions without UFB. Abstract Ultrafine bubbles (UFB) are a novel concept that has th ..read more
