Alkaline conditions better extract anti-inflammatory polysaccharides from winemaking by-products.

Winemaking generates large amounts of by-products, a well recognized source of phenolic compounds. However, less attention has been paid to the polysaccharide-rich fraction (PRF) and effects of fractionation techniques on its potential bioactivity. Therefore, PRFs from Syrah and Tempranillo winemaking by-products were extracted under aqueous (neutral pH conditions), acidic and alkaline conditions.

Pectin Interaction with Immune Receptors is Modulated by Ripening Process in Papayas.

Dietary fibers have been shown to exert immune effects via interaction with pattern recognition receptors (PRR) such as toll-like receptors (TLR) and nucleotide-binding oligomerization domain (NOD)-like receptors. Pectin is a dietary fiber that interacts with PRR depending on its chemical structure. Papaya pectin retains different chemical structures at different ripening stages.

The sour cassava starch is a product with a good oven-expansion capacity and several applications, being especially important as an alternative for gluten-based products. However, it is obtained through natural fermentation followed by solar drying, which hinders its production and application.

Ingestion of Non-digestible Carbohydrates From Plant-Source Foods and Decreased Risk of Colorectal Cancer: A Review on the Biological Effects and the Mechanisms of Action.

The hypothesis that links the increase in the intake of plant-source foods to a decrease in colorectal cancer (CRC) risk has almost 50 years. Nowadays, systematic reviews and meta-analysis of case-control and cohort studies confirmed the association between dietary patterns and CRC risk, in which the non-digestible carbohydrates (NDC) from plant-source foods are known to play beneficial effects. However, the mechanisms behind the physicochemical properties and biological effects induced by NDC on the decrease of CRC development and progression remain not fully understood.

Fast and Furious: Ethylene-Triggered Changes in the Metabolism of Papaya Fruit During Ripening.

Papaya is a climacteric fleshy fruit characterized by fast ripening after harvest. During the relatively short postharvest period, papaya fruit undergoes several changes in metabolism that result in pulp softening and sweetening, as well as the development of a characteristic aroma. Since papaya is one of the most cultivated and appreciated tropical fruit crops worldwide, extensive research has been conducted to not only understand the formation of the quality and nutritional attributes of ripe fruit but also to develop methods for controlling the ripening process.

The Starch Is (Not) Just Another Brick in the Wall: The Primary Metabolism of Sugars During Banana Ripening.

The monocot banana fruit is one of the most important crops worldwide. As a typical climacteric fruit, the harvest of commercial bananas usually occurs when the fruit is physiologically mature but unripe. The universal treatment of green bananas with ethylene or ethylene-releasing compounds in order to accelerate and standardize the ripening of a bunch of bananas mimics natural maturation after increasing the exogenous production of ethylene.

Brazilian native fruits (BNF) remain unexplored and underutilized resources with a high potential to improve human health and wellness. In our study, five new BNF (Eugenia stipitata, Sageretia elegans, Byrsonima arthropoda, Spondias mombin andRubus rosaefolius)were evaluated for their phenolic composition by LC-ESI-QTOF-MS; and for their ROS and RNS scavenging effects (ROO, O, NO, HOCl); in vivo anti-inflammatory activity (neutrophil migration); and in vivo acute toxicity in Galleria mellonella. Eighty-six phenolic compounds were identified, including hydroxybenzoic acids, hydroxycinnamic acids, flavonoids, anthocyanins and ellagitannins, several of which had never been reported in BNF.

Polysaccharides from chayote enhance lipid efflux and regulate NLRP3 inflammasome priming in macrophage-like THP-1 cells exposed to cholesterol crystals.

The contribution of dietary fiber to decrease the risk of atherosclerosis may occur through other mechanisms besides the increased excretion of cholesterol. Although macrophages are crucial for lipid clearance, the excessive uptake of cholesterol crystals (CC) by these cells induce NLRP3 inflammasome and foam cell formation. Thus, we investigated whether the water-soluble DF from chayote (WSP) regulate CC-pretreated macrophage-like THP-1 cells.
