2. Physical-chemical characterization, bioactive compounds, and antioxidant activity of pulp and peel of the Jamelão
ABSTRACT The high production of jamelão (Syzygium cumini) during harvest and the lack of information about it emphasize the development of new processing technologies for this fruit since it has been proven that its different parts have functional properties. The objectives of this work were to evaluate the physical-chemical characteristics and to determine

4. Integrated UPLC-HRMS, Chemometric Tools, and Metabolomic Analysis of Forage Palm (Opuntia spp. and Nopalea spp.) to Define Biomarkers Associated with Non-Susceptibility to Carmine Cochineal (Dactylopius opuntiae)
Metabolomics, together with analytical methods and chemometric tools, point to new paths for selecting species that are resistant to pests and diseases. In this work, the forage palm species' metabolomic profile was investigated, and the relation between the chemical composition and resistance to Dactylopius opuntiae (carmine cochineal). The study was perfor

5. Direct steam injection pretreatment improves microwave-assisted extraction yield for total flavonoids and myricetin from Hovenia dulcis Thunb.
Abstract A direct steam injection pretreatment was added before the microwave-assisted extraction procedure for the extraction of flavonoids from seeds of Hovenia dulcis Thunb, and the antioxidant activity of flavonoid extracts was determined. Based on the experimental results, the addition of direct steam injection simultaneously increased the extraction yi

7. Mucuna pruriens fiber: nutritional, functional and biological properties
Abstract An evaluation was done of the nutritional, functional and antioxidant properties of fiber residues from Mucuna pruriens bean. Nutritional value was quantified in terms of proximate composition, total dietary fiber (TDF), insoluble dietary fiber (IDF), soluble dietary fiber (SDF) and the Van Soest fiber components. Functional value was assayed by mea

8. Physicochemical and bioactive compounds evaluation of Physalis pubescens Linnaeus
ABSTRACT Physalis pubescens L. is a UFP (unconventional food plant) that produces high quality fruits; however, in Rio Grande do Sul it is still considered a rare species. There is only few information regarding the characterization of these fruits in Brazil, and the main reports of this species are mainly focused on the pharmacology and agronomic conditions

9. Amino acids and antioxidant activities of extracts from wild edible mushrooms from a community forest in the Nasrinual District, Maha Sarakham, Thailand
Abstract Twenty two species of wild edible mushrooms were collected from Nasrinual community forest. The levels of 15 amino acids, antioxidant activity, and γ-aminobutyric acid (GABA) were determined. The 8 essential amino acids were arginine, histidine, isoleucine, leucine, lysine, phenylalanine, threonine, and valine, that they were found in all the mushr

11. Development of isotonic beverage with functional attributes based on extract of Myrciaria jabuticaba (Vell) Berg
Abstract Isotonic repositories are specially designed to promote rehydration during or after physical exercise. These beverages are processed for commercialization from synthetic flavorings and dyes with sensorial characteristics similar to those of fruits, in order to attenuate their natural acidity. The aim of the present study was to develop two formulati

12. Comparative analysis of citrus fruits for nutraceutical properties
Abstract Fruits and vegetables (F and V) are valuable for their micronutrients, but many F and V in diverse growth areas have not been scientifically validated for these components. The nutraceutical characteristics of the pulp of eight citrus fruits grown in Pakistan were, therefore, investigated. Expectedly, the fruits differed in moisture (86.9-88.9%), as
