Abstract To evaluate the feasibility of acidified sodium benzoate (NaB) as alternative washing solutions of fresh produce, the survival of inoculated pathogens, the background molds and yeasts counts, and quality parameters were compared during 4 and 21 °C storage of cherry tomatoes washed with 3000 ppm NaB at pH 2.0, 200 ppm free chlorine at pH 6.5, water adjusted to pH 2.0, and distilled water. The acidified NaB solution was the most effective in reducing the population of Escherichia coli O15...

Abstract Caffeic acid phenethyl ester (CAPE) is a natural compound with anticancer activities but has low water solubility. In this work, sucrose fatty acid ester (SFAE) was used to nanoencapsulate CAPE in aqueous propylene glycol (PG) with a temperature-cycle method by heating at 90 °C for 20 min and cooling to 21 °C, followed by additional heating at 90 °C for 5 min and cooling to 21 °C. A higher amount of PG facilitated encapsulation with up to 0.1%w/w CAPE in 1.0% w/w SFAE. Additional 0.3%w/...

Caffeic acid phenethyl ester (CAPE) has high cytotoxicity against various cancer cells but has low water solubility and poor bioavailability. The objective of this work was to study a fully-dilutable oil-in-water microemulsion as a delivery vehicle of CAPE and the impacts on cellular uptake and expression of relevant proteins. Up to 3.30% w/w CAPE was dissolved in the microemulsion with droplets smaller than 20 nm and stable in 180 days. CAPE in the microemulsion had the significantly increased ...

Abstract Concerns about undesirable by-products from chlorine sanitation of fresh produce and the limited efficacy with the presence of organic matter, have led to studies on alternative washing solutions. The aim of this study was to evaluate the antibacterial activities of acidified sodium benzoate (NaB) solutions against Escherichia coli O157:H7, Salmonella enterica and Listeria monocytogenes in growth medium and on cherry tomatoes. Experimentally, the minimum inhibitory concentrations (MICs)...

Abstract Listeria monocytogenes is a Gram-positive opportunistic human pathogen and it remains a significant cause of foodborne illnesses. A variety of natural and synthetic compounds have been studied to inhibit the growth of L. monocytogenes in foods. Antimicrobial combinations with synergistic antilisterial properties can reduce the dose of each antimicrobial, which can be further enhanced by chelating compounds. Therefore, the objective of this study was to determine antilisterial properties...

The self-emulsification of oils containing dissolved solutes is not only an intriguing phenomenon but is also of practical interest in the delivery of agricultural chemicals and drugs. Herein, a facile one-step self-emulsification of eugenol with tunable release rates of encapsulated lipophilic compounds was enabled simply by gently mixing eugenol with modified rice proteins (MRPs). Due to binding with eugenol by hydrophobic interactions lowering the oil/water interfacial tension, MRPs underwent...

Abstract Microemulsions are suitable for simultaneous delivery of flavour oils and lipophilic bioactive compounds in transparent beverages. In the present study, the feasibility of delivering β-carotene in microemulsions formulated with peppermint oil and a blend of Tween® 20 and various amounts of sunflower lecithin was investigated. The poorly water- and oil-soluble β-carotene was dissolved in the transparent microemulsions that had particles smaller than 10 nm and were stable during ambient s...
