The foam mat drying is a good way of dehydrating liquids foods in short times. Due to the porous structure of the foamed materials, mass transfer is enhanced leading to shorter dehydration times. This technique can be successfully employed for drying a variety of fruit juice concentration and pulps. The dried powders have good reconstitution characteristics. These studies are particularly appli...

Different cellulose pulps were produced from sulfur-free chemical treatments of Empty Palm Fruit Bunch Fibers (EPFBF), a by-product from palm oil processing. The pulps were microfluidized for deconstruction into nanofibrillated cellulose (NFC) and nanopaper was manufactured by using an overpressure device. The morphological and structural features of the obtained NFCs were characterized via ato...

Dietary fibers, major phenolics, main minerals, and trace elements in persimmons and apples were analyzed and compared in order to choose a preferable fruit for an antiatherosclerotic diet. Fluorometry and atomic absorption spectrometry following microwave digestion were optimized for the determination of major phenolics and minerals. Total, soluble, and insoluble dietary fibers, total phenols,...

The purpose of this study was to determine the effect thermal vacuum processing and without on content bioactive compounds antioxidant activity low-calorie mixed Brazilian cerrado fruit jam. jam consisted 60% pulp Marolo, soursop sweet passion fruit, 40% other ingredients. This utilized a completely randomized design evaluate activity, total phenolic profile content, carotenoid profile, ascorbi...

Background: The energy crisis and climate change necessitate studying and discovering of new processes involved in the production of alternative and renewable energy sources. Very high gravity (VHG) fermentation is one such process improvement aimed at increasing both the rate of fermentation and ethanol concentration. The technology involves preparation and fermentation of media containing 300...

Fruit wastes are one of the main sources of municipal waste. In order to explore the potential of fruit wastes as natural resources of bioactive compounds, the antioxidant potency and total phenolic contents (TPC) of lipophilic and hydrophilic components in wastes (peel and seed) of 50 fruits were systematically evaluated. The results showed that different fruit residues had diverse antioxidant...

The harvesting, utilization and marketing of indigenous fruits and nuts have been central to the livelihoods of the majority of rural communities in African countries. In this study we report on the content of dietary fiber, minerals and selected organic acids in the pulps and kernels of the wild fruits most commonly consumed in southern Mozambique. The content of soluble fiber in the pulps ran...

ABSTRACT Fruit pulps undergo temperature variations during processing, leading to viscosity changes. This study aimed analyse the rheological behaviour of macaíba pulp at different temperatures (10 50 ºC, with 5 ºC increments) and speeds (2.5 200 rpm, totalling 17 speeds). Experimental measurements were performed in a Brookfield viscometer, fitting Ostwald-de-Waele, Mizrahi-Berk, Herschel-Bulkl...

Açai is an important commercial fruit produced in the northeastern region of Pará state, Brazil. In 2002, it represented 66% of all fruit production and increased to 76% in the following year (COSTA; ANDRADE; SILVA, 2004). The Secretary of Agriculture of the State of Pará estimated that the açai production in 2004 was of 350 thousand tons of fruits, 35% more than in 2003. The exports of the fro...
