Ethanol/water organosolv pulping was used to obtain sugarcane bagasse pulp that was bleached with sodium chlorite. This bleached pulp was used to obtain cellulosic films that were further evaluated by Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), and scanning electron microscopy (SEM). A good film formation was observed when temperature of 74 degrees C and baths of distilled water were used, which after FTIR, TGA, and SEM analysis indicated no significant difference between the reaction times. The results showed this to be an interesting and promising process, combining the prerequisites for a more efficient utilization of agro-industrial residues.

Structural and Physicochemical Properties of Starch from Rejected Chestnut: Hydrothermal and High-Pressure Processing Dependence

Enrique Pino-Hernandez, Luiz Henrique Fasolin, Lina F. Ballesteros, Carlos A. Pinto, Jorge A. Saraiva, Luis Abrunhosa, Jose Antonio Teixeira

Summary: This study investigated the impact of high-pressure processing (HPP) and hydrothermal treatments (HT) on rejected chestnut starch. The results showed that HPP did not induce starch gelatinization and increased the size and resistant starch content of the granules. The HPP-treated starch also exhibited modified pasting properties and a novel gel structure.

Brazilian Table Olives: A Source of Lactic Acid Bacteria with Antimycotoxigenic and Antifungal Activity

Luara Simoes, Natalia Fernandes, Jose Teixeira, Luis Abrunhosa, Disney Ribeiro Dias

Summary: Food and feed contamination by fungi, especially toxigenic ones, is a global concern. Lactic acid bacteria (LAB) have been gaining attention for their antifungal and anti-mycotoxin properties. This study tested 14 LAB strains isolated from naturally fermented Brazilian table olives for their ability to inhibit the growth of certain fungi and reduce mycotoxin production. The results showed that certain LAB strains exhibited strong antifungal activity and reduced the production of mycotoxins such as Aflatoxin B1, ochratoxin A, and patulin. These findings demonstrate the potential of LAB strains as natural agents to control toxigenic fungi and their mycotoxins in fermented products.

Systems biology's role in leveraging microalgal biomass potential: Current status and future perspectives

Emanuel Cunha, Vitor Sousa, Pedro Geada, Jose A. Teixeira, Antonio A. Vicente, Oscar Dias

Summary: Microalgae are a sustainable and renewable source for various compounds used in industries such as cosmetics, food, and pharmaceuticals. However, their commercialization faces challenges due to low biomass and productivity. Strategies to enhance cost-effectiveness in microalgae cultivation focus on optimizing nutrient needs and environmental factors. Genome-scale metabolic (GSM) models aid in understanding metabolic processes and can be used to optimize compound and biomass production. This review provides an overview of key considerations and strategies in microalgae cultivation, emphasizing the use of GSM models for in silico-guided optimization.

Summary: This study aims to evaluate the use of derived hemicellulose fractions from the alkaline extraction of corncob as a carbon source in the production of XG. The results indicate that strain 629 provides the higher yield of XG while using a fermentation medium containing saccharose, hemicellulose fractions, and salts. Corn cob is proven to be a promising sustainable alternative carbon source in the obtention of XG, improving the economic viability of the process within a biorefinery context.

Incorporation of Solid Lipid Nanoparticles into Stirred Yogurt: Effects in Physicochemical and Rheological Properties during Shelf-Life

Raquel F. S. Goncalves, Rui Rodrigues, Antonio A. Vicente, Ana C. C. Pinheiro

Summary: The aim of this study was to develop a yogurt fortified with curcumin by encapsulating it in solid lipid nanoparticles (SLNs). The incorporation of curcumin-loaded SLNs did not significantly affect the pH and titratable acidity of the yogurt during its shelf-life. However, the yogurt with SLNs showed slightly higher syneresis values and a stronger yellow color compared to the control. Overall, the addition of curcumin-loaded SLNs did not impact the physicochemical and rheological stability of yogurt during shelf-life, indicating a promising application for the development of new functional foods.

Summary: Microalgae have gained attention as a promising feedstock for healthier food products, but high production costs and low productivities remain a challenge. This study used a two-step optimization strategy to maximize biomass production of a Chlorella vulgaris strain under heterotrophic conditions. After studying 24 variables, (NH4)2SO4, MgSO4middot7H2O, and C6H12O6 were identified as factors with a significant impact on biomass concentration. Optimization of the culture medium led to a 99.6% increase in biomass and a 48.0% increase in carbohydrate production.

Laura Alti-Palacios, Juana Martinez, Jose A. C. Teixeira, Jose S. Camara, Rosa Perestrelo

Summary: This study aimed to investigate the impact of cold pre-fermentative maceration (CPM) treatment on the aromatic and sensory properties of white wines from four grape varieties. A total of 62 aroma compounds were identified using HS-SPME/GC-MS. CPM treatment increased the relative concentration of alcohols, esters, and acids, while the impact on terpenoids varied with grape variety and vintage. Esters made the most significant contribution to the sensory properties, enhancing floral and fruity notes.

Summary: Tomato by-products from processing industries in Portugal have the potential to be reused as a source of bioactive compounds. However, there is a lack of reliable national data on these by-products and their physicochemical properties, which hinders effective waste management planning. In this study, selected Portugal companies were recruited to obtain representative samples of by-products, and their physicochemical composition was evaluated. Additionally, an environmentally friendly method called ohmic heating (OH) was used to explore new safe value-added ingredients from these by-products.
