Development of chitosan-based films with invertase enzyme for active packaging: Physicochemical parameters, structure, application, and storage.

The use of active packaging made from biodegradable polymers can contribute to the environment and to the food industry by increasing the shelf life of their products. This study aimed to produce chitosan-based films incorporated with the invertase enzyme (1, 2, 5, 9, and 10 %) as an alternative to avoid sucrose crystallization in the confectionery industry. The optimum activity of the invertase enzyme was observed at 55 °C and pH 5, thus, the films made with the film-forming solution adjusted to pH 5 and dried at 55 °C were compared with those without pH adjustment and dried at room temperature.

Case report: Additional grounds for tighter regulation? A case series of five women with zolpidem dependence from a Brazilian women-specific substance use disorder outpatient service.

Objective: This study presents a case series of five women with zolpidem dependence treated at the Drug Dependent Women Treatment Center (PROMUD), one of the first women-specific substance use disorder outpatient services in Latin America.

Methods: This was an retrospective review of medical records of patients with a diagnosis of zolpidem dependence at the Institute of Psychiatry of Clinics Hospital of University of São Paulo between December 2021 and December 2023. Description of the cases followed the Case Report Statement, Checklist and Guidelines (CARE).

Chemical Characterization, Antioxidant Potential and Phenolic Profile of the Pulp and By-Products of Black puçá (Mouriri pusa), a Fruit from the Brazilian Cerrado region.

The black puçá (Mouriri pusa) is an unconventional fruit from the Cerrado region of Brazil, commonly known as the jabuticaba of the forest. However, data on its nutritional and phytochemical composition are limited. This study investigated the nutritional composition, physicochemical characteristics, profile of carbohydrates and organic acids, phenolics and flavonoids individual, amino acids composition, bioactive substances, and antioxidant potential in the pulp, peel, and seed fractions of puçá-preto.
