Kinetics of Ultrasound-Assisted Extraction of Anthocyanin from Purple Roselle Calyces under different pH Conditions

This research presents that the higher temperature results on higher extracted anthocyanin. In addition, it was found that pH 2 was preferable for obtaining greater anthocyanin content. Employing the second-order kinetics model in this research confirmed the good fitting of the model and experimental data.

Acid Hydrolysis and Ethanol Precipitation for Glucomannan Extraction from Crude Porang (Amorphophallus Oncophyllus) Tuber Flour

Extraction of glucomannan from crude porang flour by acid hydrolysis and ethanol precipitation was studied. Effects of acid concentration, temperatures and time were investigated, kinetics model of the process was developed and the parameters were evaluated based on experimental data. New data on yield and purity of glucomannan under various conditions were obtained.

DEVELOPMENT OF THE PROCESS OF EXTRACTION OF CORN GLUTEN

The processing of corn grain allows getting starch, roughage, oil and proteins. Corn gluten is a valuable product that is obtained from corn processing to starch and molasses.  It is a pure protein that it has excellent nutritional properties. Corn gluten is not as widely used as wheat gluten. It’s mainly used for feeding farm animals and poultry, and has a short shelf life. The secondary processing of corn gluten is relevant. Besides solution of a number of environmental problems we can get a number of important products such as zein and fat-carotenoid fraction.

Екстрагування хлоридів із суміші хлоридних і сульфатних солей застосуванням етанолу

In this article the extraction of chloride from a mixture of sulfate-chloride salts by aqueous organic extractant with ethanol was investigated. It is found that using of the ratio of T:P = 1:2 and the concentration of ethanol in the extractant 50 wt. % сan get a satisfactory yield chlorine-free product that meets to potassium-magnesium.
