Summary: Plastic-based food packaging causes a serious environmental problem, driving the need to develop biodegradable films, with starch as a potential substitute for petroleum-based plastic. While starch has many advantages, its low mechanical strength and water resistance can be overcome by using nanocellulose as a reinforcement in biocomposites for food packaging.

Summary: Edible films and coatings are potential methods for preserving fresh food. Starch is commonly used for film and coating production due to its low cost and wide availability. However, additives are often needed to overcome the limitations of starch-based films. This review focuses on the effects of additives on the properties of starch-based films and coatings, and their compliance with the requirements for edible and biodegradable food packaging. The use of additives enhances the barrier properties and bioactivity of the films, and also improves their shelf stability.

Summary: This study investigated the properties of different formulations of biodegradable cassava starch/gelatin films. The results showed that increasing the amount of gelatin enhanced the thermal performance of the films, but an excess of gelatin was incompatible with starch. Additionally, increasing the gelatin ratio significantly increased the strain and decreased the tensile strength, while also increasing water vapor permeability and decreasing water solubility.

Summary: This study evaluated the application of biodegradable films modified with ascorbic acid or caffeine and dialdehyde starch in the food packaging industry. The results showed that dialdehyde starch had cross-linking and hydrophobic effects on starch-based films. The addition of vitamin C promoted crystalline structure formation and improved hydrophilicity and antioxidant activity. Caffeine addition increased film hydrophobicity but reduced crystalline order in starch.

Summary: Gastrointestinal tract (GIT) malignancies are a significant public health problem due to their increased incidence in recent years and high morbidity and mortality rates. Three-dimensional (3D) bioprinting has emerged as a useful technique to engineer cancer tissue models that mimic the tumor microenvironment (TME) more closely. However, current 3D culture models fail to fully reproduce the heterogeneity of the TME. This review provides an overview of 3D bioprinting methods, bioinks, and their application in developing gastrointestinal tumor models, as well as current challenges and future perspectives.

Summary: A novel adsorbent material was prepared by modifying chitosan to remove Copper and chromium metal ions from aqueous solution. The composite material was characterized using FTIR, TGA, SEM and XRD techniques. The adsorption capacity for Copper and Chromium ions was found to be 166.66 and 250 mgg(-1) respectively, and the adsorption process followed a Langmuir model with pseudo second-order kinetics. Thermodynamic studies revealed that the adsorption process was spontaneous and endothermic in nature.
