Making the reuse of agro-industrial wastes a reality for starch-based packaging sector: A storage case study of carrot cake and cherry tomatoes.

Cassava inner bark (CIB) and grape stalks (GS), residues from agro-industrial activities, were applied in the development of biodegradable foams by thermocompression. The samples produced with untreated stalks (sample GSWT) and with stalks only physically treated (sample GSP) presented good mechanical strength (2.1 MPa and 2.

Cassava starch-processing residue utilization for packaging development.

The starch-based film development has been extensively studied since, in general, it is possible to obtain transparent, non-toxic, odorless, good gas barrier, biodegradable, and tasteless samples. However, world hunger-related problems are a reality and the use of starches, a recognized carbohydrate source, in the packaging industry should be avoided. Thus, the use of different residual starchy can minimize the costs of production, promoting the development of innovative biomaterials, eliminating the competition with the food chain.

Influence of replacing oregano essential oil by ground oregano leaves on chitosan/alginate-based dressings properties.

Biopolymers, as chitosan and alginate, have gained prominence in the biomedical area, mainly for application in wound dressings, as partial replacements for synthetic polymers. The present work aimed to compare the influence of the antimicrobial agent incorporation form on the properties of films prepared by casting. The chitosan/alginate-based films were manufactured containing oregano essential oil (OEO) or ground oregano leaves (OR).

Influence of turmeric incorporation on physicochemical, antimicrobial and mechanical properties of the cornstarch and chitosan films.

Biopolymers have gained prominence in different areas, such as food packaging for single-use and biomedical applications, automotive field and electrostatic separation systems. The present work aims the development of films by casting based on chitosan and cornstarch incorporated with turmeric. Turmeric insertion is justified by its excellent antioxidant and pharmacological properties.

Impact of acid type for chitosan dissolution on the characteristics and biodegradability of cornstarch/chitosan based films.

Biopolymers have received considerable attention in recent years given the environmental concern related to the incorrect disposal of materials based on synthetic plastics. Starch and chitosan are good examples of raw materials of interest, and its combination can exhibit some newsworthy barrier and mechanical properties. Therefore, this study aimed to determine the impact of the acid type, acetic and lactic solutions (1% v/v), used for chitosan solubilization and the starch:chitosan proportion on the properties of cornstarch/chitosan-based films.

Effect of chitosan addition on the properties of films prepared with corn and cassava starches.

Starch and chitosan are biodegradable polymers from renewable sources that can be used to overcome the serious environmental problem caused by improper disposal of synthetic plastic materials, non-biodegradable, derived from petroleum sources. The starch-chitosan based films manufactured allow improving the better characteristics of each one, adding their good characteristics and compensating for some limitations. In this work, it was studied: two sources of starch (corn and cassava), two different modes of chitosan addition (chitosan blended in the starch filmogenic solution and chitosan as coating), and the effect of glutaraldehyde as crosslinking agent.

Valorisation of blueberry waste and use of compression to manufacture sustainable starch films with enhanced properties.

Blueberry waste from juice processing was valorised to develop starch films by compression moulding. The compression process resulted in hydrophobic films with water contact angles even higher than 100° for the films prepared with the highest blueberry waste content. Additionally, the film solubility was reduced by the incorporation of blueberry waste, regardless of the solution pH.

Development and characterization of cassava starch films incorporated with blueberry pomace.

This work is focused on the development of renewable and biodegradable films by the valorisation of wastes from food processing industries, with the aim of contributing to the development of more sustainable films. In this context, different contents of blueberry pomace (BP) were incorporated into cassava starch (CS) film forming solutions and the functional properties of the films prepared by solution casting were investigated, specifically, thermal, optical and physicochemical properties. BP-incorporated films showed good barrier properties against light, indicating their beneficial effect to prevent food deterioration caused by UV radiation when these films are used for food packaging applications.

Effect of blueberry agro-industrial waste addition to corn starch-based films for the production of a pH-indicator film.

Intelligent packaging is an emerging area of food technology that can provide better preservation and be of further convenience for consumers. It is recommended that biodegradable materials be used to develop low-impact designs for better packaging, which could benefit the environment by simply expanding their use to new areas. In this work, corn starch, glycerol and blueberry powder (with and without prior fruit bleaching) were used to produce films by casting.
