Nanotechnologies for Active and Intelligent Food Packaging: Opportunities and Risks

2017

This chapter focuses on providing a comprehensive review on the current development of nanotechnology in the field of active and intelligent packaging for food. Systems devoted to intelligent food packaging require easy-to-read, cheap, robust, and safe systems that are able to provide on time information. Food and Drug Administration (FDA) considers that evaluations of safety, effectiveness, public health impact, or regulatory status of nanotechnology products should consider any unique properties and behaviors that the application of nanotechnology may impart. The lack of regulatory support providing standardized risk assessments of engineered nanomaterials (ENM) through integration of haz…

Integrated Strategies to Improve the Quality of Wheat End-Products: Optimization of Processes and Development of Functional Food

Strategie integrate per il miglioramento qualitativo di prodotti da forno a base di grano: ottimizzazione dei processi produttivi e sviluppo di alimenti funzionali. Sono state sviluppate tecnologie applicate ai prodotti da forno per il miglioramento dei processi produttivi e lo studio di alimenti funzionali. In particolare è stato condotto uno studio su trattamenti sanitizzanti al fine di ridurre le contaminazioni microbiche (soprattutto lieviti) sul prodotto finito. E’ stata proposta una soluzione a base di perossido e argento colloidale in confronto con soluzioni fenoliche OPP. Il monitoraggio, biennale, è stato svolto nelle celle di lievitazione e raffreddamento del prodotto finito (pane…

In vitro Antifungal Activity of Biopolymeric Foam Activated with Carvacrol

2020

Background: Active packaging represents a defining strategy to improve food quality and safety of the packaged foods. This study aimed to evaluate the in vitro ability of commercial biopolymeric foams, namely Mater-Bi (MB), activated with 20% of carvacrol, to develop a completely biodegradable and compostable packaging to inhibit the growth of spoilage and pathogenic yeasts.
 Methods: MB foams, with and without carvacrol, were produced by melt mixing and the foaming process was performed in a laboratory press. The antifungal activity of foams containing carvacrol was tested applying the disk diffusion method. Statistical analysis was done using XLStat software version 7.5.2 for Excel.&…

Test procedures for obtaining representative extracts suitable for reliable in vitro toxicity assessment of paper and board intended for food contact.

2009

International audience; This paper describes the use of a suite of extraction procedures applicable to the assessment of the in vitro toxicity of paper/board samples intended for food-contact applications. The sample is extracted with ethanol, water, or exposed to modified polyphenylene oxide (Tenax) for fatty, non-fatty and dry food applications, respectively. The water extracts are directly suitable for safety assessment using in vitro bioassays. The ethanol extracts of the paper/board and of the exposed Tenax require pre-concentration to give acceptable sensitivity. This is because the in vitro bioassays can tolerate only a small percentage of added organic solvent before the solvent its…

Safety Evaluation of Food contact paper and board using Chemical Tests and in vitro Bioassays-The role of known and unknown substances

2010

International audience; In vitro toxicological tests has have been proposed as an approach to complement the chemical safety assessment of food contact materials, particularly those with a complex or unknown chemical composition such as paper and board. An EU 5th framework program project “BIOSAFEPAPER – Application of bioassays for safety assessment of paper and board for food contact” specially focused on the application of biotests to paper and board. The project included both chemical characterization and toxicological testing of a representative number of paper and board extracts prepared according to the proposed end use (wet, fatty and dry food contact). Among the concerns addressed …

Antimicrobial additives for poly(lactic acid) materials and their applications: current state and perspectives

2018

Poly(lactic acid)-based antimicrobial materials received considerable attention as promising systems to control microbial growth. The remarkable physicochemical properties of PLA such as renewability, biodegradability, and US Food and Drug Administration (FDA) approval for clinical use open up interesting perspectives for application in food packaging and biomedical materials. Nowadays, there is an increasing consumer demands for fresh, high-quality, and natural foods packaged with environmentally friendly materials that prolong the shelf life. The incorporation of antimicrobial agents into PLA-based polymers is likely to lead to the next generation of packaging materials. The development o…

Halloysite nanotubes loaded with peppermint essential oil as filler for functional biopolymer film

2016

Abstract The purpose of this paper is to show how a functional bionanocomposite film with both antioxidant and antimicrobial activities was successfully prepared by the filling of a pectin matrix with modified Halloysite nanotubes (HNT) containing the essential peppermint oil (PO). Firstly, HNT surfaces were functionalized with cucurbit[6]uril (CB[6]) molecules with the aim to enhance the affinity of the nanofiller towards PO, which was estimated by means of HPLC experiments. The HNT/CB[6] hybrid was characterized by several methods (thermogravimetry, FT-IR spectroscopy and scanning electron microscopy) highlighting the influence of the supramolecular interactions on the composition, therma…
