“…To produce nanostarch, it is important to separate crystalline starch from the amorphous and crystalline complexes. Several methods are used for processes of amylose extraction, such as enzyme hydrolysis [77], acid hydrolysis [78], precipitation [79], and mechanical micro-fluidizer treatment [80].…”

Biopolymers have been used in packaged foods to tackle environmental hazards due to their biodegradability and non-toxic nature. In addition to these merits, they have also several demerits such as poor mechanical properties and low resistance towards water. Nanomaterials have attracted great interest in recent years due to their phenomenal properties that makes them precedent in applications for food packaging as they enhance the mechanical, thermal and gas barriers properties, without compromising with the ability to become non-toxic and biodegradable. The most important nanomaterials used in food packaging are montmorillonite (MMT), zinc oxide (ZnO-NPs) coated silicate, kaolinite, silver NPs (Ag-NPs) and titanium dioxide (TiO 2 NPs) as these, nanomaterials coated films makes a barrier against oxygen, carbon dioxide and favour compounds. They also possess oxygen scavenging capability, antimicrobial activity and tolerance towards temperature. The most difficult task related to the preparation of these nanocomposites is their complete distribution within the polymer matrix and their compatibility. Therefore, there is an increasing demand for improvement in the performance of nano-packaging materials including mechanical stability, degradability and effectiveness of antibacterial property.

Plants are the most abundant bioresources, providing valuable materials that can be used as additives in polymeric materials, such as lignocellulosic fibers, nano-cellulose, or lignin, as well as plant extracts containing bioactive phenolic and flavonoid compounds used in the healthcare, pharmaceutical, cosmetic, and nutraceutical industries. The incorporation of additives into polymeric materials improves their properties to make them suitable for multiple applications. Efforts are made to incorporate into the raw polymers various natural biobased and biodegradable additives with a low environmental fingerprint, such as by-products, biomass, plant extracts, etc. In this review we will illustrate in the first part recent examples of lignocellulosic materials, lignin, and nano-cellulose as reinforcements or fillers in various polymer matrices and in the second part various applications of plant extracts as active ingredients in food packaging materials based on polysaccharide matrices (chitosan/starch/alginate).In this review various recent applications of plant-based additives (lignocellulosic fibers/nano-cellulose as well as bioactive plant extracts) as reinforcements and active ingredients in food packaging materials are illustrated. Natural polysaccharide biopolymers (such as chitosan/starch/alginate) are nontoxic, biodegradable, biocompatible, and largely used in food packaging: Chitosan is known for its broad antimicrobial activity and its excellent film-forming properties; alginates have good film-forming properties, retain moisture, reduce microbial counts, and retard oxidative off-flavors; and starch is also particularly important for its cheap price and its frequency in nature. For these reasons, this review will present applications of plant extracts as active ingredients in natural polysaccharide biopolymers: chitosan/starch/alginate. Classification of Natural Biodegradable Polymers and AdditivesNatural biodegradable polymers and additives are polymers formed naturally by the living organisms by enzyme-catalyzed reactions and reactions of chain growth from monomers which are formed inside the cells by complex metabolic processes [5].Natural additives can be high molecular weight (natural polymers), such as proteins (collagen, silk, and keratin), carbohydrates (starch and glycogen), lignin, cellulose, high molecular weight phenolics (tannins and derivatives), and low molecular weight active substances, such as cold-pressed oils, essential oils (organic volatile compounds, generally of low molecular weight,

“…An example is represented by the cellulose acetate, which, however, still contemplates high production costs. Moreover, cellulosic fibers when added to starch made the material less hydrophilic and significantly improved its mechanical and gas permeability properties [28].…”

Plastics has been an integral part of our lives for the last century as the main material for various useful commodity items. Irony of fate, the same specific properties that make plastics ideal to create such a wide range of products are also responsible for the present dramatic environmental pollution. What suggestions do the technological innovations currently suggest to solve this worldwide problem? Among the others, one is to replace the traditional plastics with alternative materials derived from non-oil polymers capable of being degraded in months and not in years or centuries. But the research in this field is relatively new and undoubtedly there are still developments that need to be made. Thus, we must be aware that the plastic age is at sunset and the bio-plastics sun is just rising on the horizon.
