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 Alternative postharvest sanitizers to chlorine are of increasing interest for many organic growers and consumers. An emulsion of clove bud oil (CBO; 0.2 and 0.5%) or thyme oil (0.2 and 0.5%) was evaluated as a sanitizer for produce washing against a five-serovar cocktail of Salmonella on snacking peppers and compared for antimicrobial efficacy with sodium hypochlorite (200 ppm). To further evaluate these compounds, the sanitation efficacy of an emulsion was examined after the addition o...

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/...

Abstract A low-cost, convenient and organic solvent-free approach was investigated to nanoencapsulate curcumin (CCM) in myofibrillar proteins (MPs) as a potential strategy to improve the oxidative stability of marinated meat products. The encapsulation was enabled by shifting CCM–MP mixture to pH 12 and then pH 7 at different ionic strengths. Stable CCM–MP nanocomplexes were formed at 0.3, 0.6 and 0.9 mol/L NaCl, resulting from the exposure of hydrophobic residues of MPs at alkaline pH to bind w...

Biocompatible materials with ice recrystallization inhibition (IRI) activity have potential applications in several fields. Emerging studies have associated the IRI activity of antifreeze proteins/glycoproteins and several mimics of synthetic materials with a facially amphipathic structure. Nanocelluloses are a new family of renewable materials that demonstrate amphiphilicity. Herein the IRI activity of cellulose nanocrystals (CNCs) and 2, 2, 6, 6-tetramethylpiperidine-1-oxyl oxidized cellulose ...

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 Fabrication of stable aqueous foams is significant to various food and non-food applications. In the present study, we report aqueous foams with a volume maintained for 14 days after whipping suspensions with intercalated montmorillonite (MMT) platelets coated with sodium caseinate (NaCas). Intercalating MMT preheated at 60 °C for 1 h with room temperature NaCas solution resulted in a good extent of intercalated and exfoliated MMT platelets coated with NaCas. The high extent of MMT inte...

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)...

A pH-cycle method based on preparing an alkaline solution of zein followed by neutralization with an acid can be used to prepare zein nanoparticles. In the present work, partial alkaline hydrolysis of propylene glycol alginate (PGA) to a lower pH was studied to prepare binary zein–PGA nanocomplexes and ternary complexes with additional sodium caseinate (NaCas). 0.5% or more PGA was sufficient to reduce the pH to 7.5 or lower, eliminating the need for titration, and resulted in simultaneous nanoc...
