Total and Free Hydrogen Cyanide Content and Profile of Bioactive Amines in Commercial , a Traditionally Derived Cassava Product Widely Consumed in Northern Brazil.

is a broth derived from cassava roots which is produced after the spontaneous fermentation of (the liquid portion obtained by pressing cassava roots), followed by cooking. This product is widely consumed along with traditional dishes in the Brazilian Amazonia and is already used in different places worldwide. In this study, obtained from the markets of Belém (Pará, Brazil) and produced using agroindustrial (11 samples) and non-agroindustrial (11 samples) units were investigated to determine their physicochemical characteristics, total and free HCN contents, and free bioactive amine profiles.

Stability Kinetics of Anthocyanins of Grumixama Berries ( Lam.) during Thermal and Light Treatments.

Grumixama ( Lam.) are red-colored fruits due to the presence of anthocyanins. In this paper, anthocyanin-rich extracts from grumixama were submitted to different temperatures and light irradiations, with the aim of investigating their stabilities.

Application of pulsed-vacuum on the salt impregnation process of pirarucu fillet.

The influence of the pulsed-vacuum impregnation (PVI) and periodic pulsed-vacuum impregnation (PPVI), and the temperature, on the salting process of pirarucu fillet was studied. For this, the dorsal region of the fish in the slab-shaped (60 mm × 20 mm × 5 mm) and sodium chloride solution (30 g/100 g NaCl) were used. The process was conducted at different temperatures (10 °C - 40 °C) and the following pulsed-vacuum conditions: initial vacuum pulse (5 min at 10 kPa) and alternating periods of vacuum pulse (5 min at 10 kPa) and atmospheric pressure (101 kPa) for 5 min, 10 min and 15 min intermittently.

Combined osmotic dehydration and drying process of pirarucu () fillets.

The osmotic dehydration (OD) and complementary drying of pirarucu () fillets were studied. Pieces of the dorsal portion of pirarucu (60 mm × 20 mm × 10 mm) underwent OD in a binary solution (NaCl-water) with the application of vacuum pulse following a central rotatable composite design. The effect of the following process variables was assessed: temperature (20-40 °C), osmotic solution concentration (15-25% NaCl), and vacuum pulse pressure (7-101 kPa) on water loss (WL), solid gain (SG), and water activity (a).
