Starch-based films with phenolic extracts could replace the use of petroleum-based plastics. In this study, octenyl succinate starch (OSS) films with pecan nutshell extract (PSE) or hazelnut skin extract (HSE) were prepared. The water resistance, as well as the optical, physical, mechanical, and biodegradable properties of these films, were investigated. The PSE and HSE improved the water resistance (decreasing the solubility to 17% and increasing the contact angle to 96.80°) and UV-light barrier properties of the films. For PSE and HSE, as their concentrations increased, the film rigidity decreased since these extracts acted as plasticizers. Micrographs obtained by scanning electron microscopy (SEM) depicted a homogeneous surface as a result of extracts dispersion through the polymeric matrix and the interactions between the phenolic compounds (PC) of the extracts and the OSS. The phenolic extracts from nut by-products and octenyl succinic anhydride (OSA) starch could be used to develop films to replace the conventional plastics.

Cardiovascular risk factors begin in childhood and track into adulthood, increasing the possibility of impaired cardiometabolic health. Adopting healthy dietary patterns can help curb childhood obesity, a worrisome epidemic problem at present. In the era of personalized nutrition, dietary recommendations should be adapted to different stages of life, including children (older than 3 years) and adolescents.

Mycotoxins pose significant health risks due to their prevalence in food products and severe health implications, including carcinogenicity. This study investigates the bioavailability of mycotoxins aflatoxin B1 (AFB1), ochratoxin A (OTA), and zearalenone (ZEN) individually and combined, in the presence of identified polyphenols from tiger nut beverage (TNB) and tiger nut by-product (TNBP) using the in vitro model Caco-2 cells, which simulates the human intestinal barrier. The objective is to understand how bioactive compounds from TNBP can mitigate the effects of AFB1, OTA and ZEN (and their combination) by bioavailability interference, contributing to safer food products and innovative food safety strategies.

The Amazon Region (AR), with its vast biodiversity and rich natural resources, presents a unique opportunity for the development of sustainable polymer composites (PCs) reinforced with residues from both timber and agro-extractivism industries. This study explores the potential of Amazonian residues, such as sawdust, wood shavings, and agro-industrial by-products such as açaí seeds and Brazil nut shells, to enhance the mechanical, thermal, and environmental properties of polymer composites. By integrating these natural materials into polymer matrices, significant improvements in the composite performance were achieved, including increased tensile strength, thermal stability, and biodegradability.

Consumers are raising concerns over the ethical and social acceptability of feeding regimes used in animal-based food productions. However, the use of agro-industrial by-products, such as hazelnut skins as a strategy to reduce the environmental impact of livestock production may be negatively perceived from the consumer's perspective. Here, we investigated the factors predicting consumers' intentions to try meat obtained from cattle fed hazelnut skins.
