Some of the current challenges faced by the food industry deal with the natural ripening process and the short shelf-life of fresh and minimally processed products. The loss of vitamins and minerals, lipid oxidation, enzymatic browning, and growth of microorganisms have been the main issues for many years within the innovation and improvement of food packaging, which seeks to preserve and protect the product until its consumption. Most of the conventional packaging are petroleum-derived plastics, which after product consumption becomes a major concern due to environmental damage provoked by their difficult degradation. In this sense, many researchers have shown interest in edible films and coatings, which represent an environmentally friendly alternative for food packaging. To date, chitosan (CS) is among the most common materials in the formulation of these biodegradable packaging together with polysaccharides, proteins, and lipids. The good film-forming and biological properties (i.e., antimicrobial, antifungal, and antiviral) of CS have fostered its usage in food packaging. Therefore, the goal of this paper is to collect and discuss the latest development works (over the last five years) aimed at using CS in the manufacture of edible films and coatings for food preservation. Particular attention has been devoted to relevant findings in the field, together with the novel preparation protocols of such biodegradable packaging. Finally, recent trends in new concepts of composite films and coatings are also addressed.

Propolis (bee glue) is a sticky resinous material applied by honey bees Apis mellifera L. as a building material in their hives and as a defensive substance against infections. Propolis has been used as a remedy in traditional medicine systems all over the world, mainly to treat wounds and burns, sore throat, stomach ulcer, etc. Modern science has confirmed the antimicrobial and antiviral action of propolis, and has discovered numerous other beneficial pharmacological properties of bee glue: immunomodulating, anti-inflammatory, antiobesity, antitumor, and many others. For this reason, significant number of products containing propolis have been developed and commercialised: medical devices, over-the-counter preparations, health foods and beverages, cosmetics. This review is not dealing with propolis applications in improvement and protection of human health. Instead, it is focused on some new and promising areas of propolis use and innovative propolis containing products, emerging in the last few years: improving growth performance of livestock, food preservation, food packaging, textile materials for biomedical application, etc.

In Africa, the importance of NTFPs in the livelihood security is well recognized and these products represent vital sources of income for poor population. However, the sales chain of Marantaceae leaves is informal in Gbado-Lite and there is no information available on this sector for the promotion of the sale of NTFPs at the local level to reduce poverty and protect the environment as well as to conserve biodiversity. This survey shows that mostly female (55%) carries out the sale of Marantaceae leaves in Gbado-Lite. Among traders, 37.5% are illiterate, 32.5%, 20% and 10% have a secondary, primary and university education respectively. Regarding the marital status, 52.5% of respondents are divorced, 25% are widows and 22.5% are married. While 40% of respondents are unemployed, 30% are farmers while housewives and pupils account for 17.5% and 12.5% respectively. Our respondents know seven other non-woody forest products. These include: Mushrooms (27.5%), Caterpillars (22.5%), Marantaceae leaves (20%), honey (17.5%), snails and game (5% each) and vines (2.5%). Marantaceae leaves are first used for food packaging (47.5%), food preservation (35%), building material (10%). The forest accounts for 52% of the total harvesting habitat of Marantaceae leaves. It is followed by fallow (25%), fields (15%) savannah (8%) respectively. This sale allows the schooling for children (27.5%); health care (20%); food purchase (17%); beverage purchase (12.5%). The majority of respondents believe that these leaves are not well managed after use and therefore pollute the environment because of the lack of a waste collection structure. Yet, they are biodegradable and should be used to make compost for crops in Gbado-Lite.

AbstractAntimicrobial packaging is one of the most promising active packaging systems. Antimicrobial packaging is the packaging system that is able to kill or inhibit spoilage and pathogenic microorganisms that are contaminating foods. A tremendous effort has been made over the last decade to develop and test films with antimicrobial properties to improve food safety and shelf life. For food preservation, chitosan films are very effective. Chitosan has widely been used in antimicrobial films, to provide edible protective coating, dipping and spraying for the food products due to its antimicrobial properties. Chitosan can be formed into fibers, films, gels, sponges, beads or nanoparticles. Chitosan films have been used as a packaging material for the quality preservation of a variety of food. Chitosan has great potential for a wide range of applications due to its biodegradability, biocompatibility, antimicrobial activity, non-toxicity and versatile chemical and physical properties. The present review outlines the preparation and antimicrobial activity of chitosan based films.

Abstract Lactic acid bacteria (LAB) have acted in food fermentations through the ages due to their safety and resilience to specific harsh conditions of high salinity or low pH present in food and gut where they live. Their interaction with human technological development started in food but goes beyond, as some LAB contribute to the health of humans and animals as probiotics. The stress tolerance of LAB also makes them excellent, robust industrial microorganisms for production of lactic acid and other chemicals. The lactic acid market has had a high growth rate in the last decade mainly due to expansion of poly-lactide production. Poly-lactides are biocompatible, thermostable and biodegradable polymers of lactic acid, suitable for use in food packaging or in medicine, as scaffolds, implants or delivery systems. The ability of LAB to grow on complex waste substrates but efficiently produce selected isomers of lactic acid has positioned them at the core of bio-based packaging production, and this field is expected to grow in the future. Therefore, LAB are important for food - for preservation, flavour and packaging, but also beyond food – as probiotics, paraprobiotics and postbiotics. Recent trends in these fields of LAB application are analysed in this work.

Over the years, there has been an effort to extend food shelf life so as to reduce global food waste. The use of natural biodegradable materials in production procedures is more and more adopted nowadays in order to achieve cyclic economy targets and improve environmental and human health indexes. Active packaging is the latest trend for food preservation. In this work, polystyrene was mixed with natural NaMt, OrgNaMt montmorillonite, and oregano essential oil to develop a new packaging film. Strength, oxygen and water-vapour permeation, blending and homogeneity, and antimicrobial and antioxidant activity were measured as basic parameters for food packaging films characterization. Instruments such as a tensile measurement instrument, XRD, FTIR, DMA, OPA (Oxygen Permeation Analyzer), and other handmade devices were used. Results showed that polystyrene could be modified, improved, and exhibits food odour prevention characteristics in order to be used for applications on food active packaging. The material with the code name PS5OO@OrgMt qualified between the tested samples as the most promising material for food active packaging applications.
