Summary: This study focuses on the preparation of biodegradable films from natural polymer starch modified by cellulose and chitin with incorporation of extracts from date seeds, aiming for potential application as food packaging materials. The addition of date seed extracts to the films improved their tensile strength and resulted in antioxidant and antimicrobial properties. The films were found to be easily degradable in composting soil within 5-7 weeks, and economic analysis suggested the feasibility of their production in terms of cost.

Summary: The network strength of starch hydrogels was enhanced by adjusting the pH value and adding iron ions, leading to improved mechanical and swelling properties. The starch hydrogel with a pH value of 11.5 and containing Fe3+ exhibited a complex modulus above 3400 Pa, and its structure became more compact with increasing pH value. Moreover, the hardness and swelling rate of the hydrogel increased with pH value and addition of 0.5 mol/L Fe3+, indicating that simple adjustments to pH and iron ion concentrations can improve the mechanical properties of starch hydrogels.

Summary: This study evaluated the viscosity of 5% w/v suspensions containing thermally inhibited (TI), chemically modified (CM), and granular cold-swelling (GCS) starch with the addition of various amounts of pea protein isolate (PP1). The results showed synergistic interactions between PP1 and TI starch, with the addition of PP1 significantly increasing viscosity, reaching a maximum at a PP1 mass ratio of 0.2-0.25. These interactions were mainly electrostatic, with minor contributions from hydrogen bonding. Other pea protein isolates (PP2 and PP3) had limited effects on viscosity.

Summary: Starch is a major component in pea seeds, but its utilization is currently limited to low-value markets. The increasing demand for pea protein poses a challenge for the pea fractionation industry to find new markets for starch valorization. There are gaps in our understanding of the genetic mechanism underlying starch metabolism, its relationship with physicochemical properties, and how it can be tailored for innovative applications.

Summary: The study evaluated the impact of substituting wheat flour with three different pretreated green pea flour on fresh bread quality. It was found that bread made with conventionally milled and pre-cooked green pea flour showed similar characteristics to the control, while higher addition levels decreased specific volume and increased firmness. Incorporating legume flour delayed staling and increased proteins and fiber in the bread. Pre-heated flour increased starch digestibility. Overall, pre-cooked and soaked under-pressure-steamed green pea flour can be valuable ingredients for making soft and stable bread.

Summary: Composite films made of pea starch and ε-polylysine as the matrix, with glycerol and sodium alginate as the plasticizers, were investigated. The properties of these films, including rheological and mechanical properties, Fourier transformed infrared spectroscopy, water vapor and oil permeability, microstructure, thermogravimetry, and antimicrobial properties, were analyzed. The results showed that the mass ratio of St/PL greatly influenced the properties of the films, with higher PL content leading to decreased tensile strength, increased fracture elongation, increased permeability, and reduced oil resistance. Moreover, the antimicrobial properties of the films improved with higher mass ratios of PL, with the strongest inhibition observed against B.subtilis.

Summary: In this study, microcrystalline butyrylated pea starch (MBPS) was synthesized with higher contents of resistant starch (RS) by esterification with butyric anhydride (BA) using microcrystalline pea starch (MPS) as the raw material. The presence of BA was confirmed through FTIR and 1H NMR analysis, and the irregular shape of MBPS was observed by SEM. The functional properties of MBPS were significantly improved compared to MPS, with higher decomposition temperatures and increased RS content.

Summary: The study showed that the concentration of pumpkin flour matrix and natural filler significantly affected the properties of edible films, potentially leading to the redefinition of resistant starch classification. The addition of natural nanofiller had varying plasticizing effects on edible films at different concentrations, without significantly impacting their digestibility.

Summary: This research aimed to investigate the effect of starch gelatinization and swelling degree on the lubrication properties of starch aqueous suspensions. Different types of maize starch showed varied swelling capacities, resulting in different lubrication properties. The presence of saliva and salivary proteins also played a role in determining the lubrication properties of the starch suspensions.

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.
