Geranium (Pelargonium graveolens) is known for being an aromatic plant rich in bioactive compounds with antibacterial properties. In this study, geranium essential oil (GEO) was extracted and encapsulated in ultrafine bean starch fibers produced by electrospinning as an antibacterial agent. GEO revealed a composition rich in volatile compounds, including citronellol, cis-geraniol, β-linalool, citronellyl formate, and linalool formate. In its free form, GEO exhibited high antibacterial activity against pathogenic bacteria strains (L. monocytogenes, S. aureus, and E. coli). The bean starch fibers, produced with and without the addition of GEO, were uniform and continuous, with an average diameter ranging from 249 to 373 nm. Confocal analysis indicated a uniform distribution of GEO in the fibers, with a loading capacity of 54.0 %, 42.9 %, and 36.5 % for 20 %, 30 %, and 40 % GEO concentrations, respectively. Remarkably, fibers containing 40 % GEO showed a significant reduction in tested bacteria (L. monocytogenes, S. aureus, and E. coli), suggesting promising applications in preventing losses and extending the shelf life of food through active packaging.

Mung bean hull polyphenols (MBPs) have the potential to retard starch digestion by altering its multi-scale structures. However, the regulatory mechanism and the key structural characteristics that contribute to digestion resistance remain unclear. In this study, MBPs were non-covalently interacted with wheat starch (WS) under hydrothermal treatments.

Diet digestibility can vary based on factors such as the type of ingredients, processing techniques, formulation, fiber content, and nutrient interactions. Unlike proteins and fats, there is no specific carbohydrate requirement, which typically constitutes 30%-60% of commercial dried dog foods. Because of the significant proportion of carbohydrates in dog food, this study aimed to evaluate the differences in nutrient digestibility among barley, brown rice, corn, mung bean, and rice, which are common carbohydrate sources in commercial dog foods.

The environmental impact of plastic waste is a growing global challenge, primarily due to non-biodegradable plastics from fossil resources that accumulate in ecosystems. Biodegradable polymers like polyhydroxyalkanoates (PHAs) offer a sustainable alternative. PHAs are microbial biopolymers produced by microorganisms using renewable substrates, including agro-industrial byproducts, making them eco-friendly and cost-effective.

In response to the growing demand for high-quality food ingredients, starches from underutilised sources like quinoa and faba bean are gaining attention due to their unique properties and high tolerance to adverse environmental conditions. Acid hydrolysis is a well-established chemical method for producing modified starch with improved solubility, lower gelatinisation temperature, and reduced pasting viscosity. However, various outcomes can be achieved depending on the type of starch and modification conditions.
