Arrowroot Starch

Abstract In the current work, physicochemical properties of arrowroot starch and thermal properties of glycerol/arrowroot starch membranes were investigated. Arrowroot starch exhibited high purity (starch content >99%) with amylose content >40% and granule size dispersion between 29 and 126 μm. Arrowroot starch has a gelatinization temperature of 63.94°C and a B-type crystalline structure. Arrowroot starch, in combination with three levels of glycerol, was used to manufacture membranes by casting method. Increasing the plasticizer effect due to glycerol content increased the water weight loss of the membranes at temperatures higher than 110°C. Additionally, the onset temperature of the endothermic peak observed by differential scanning calorimetry and associated to water removal from the membranes changed with glycerol content. Physicochemical and thermal properties of arrowroot starch and glycerol/arrowroot starch membranes were similar to those reported previously for other starch sources. From the data obtained in this study, it is clear that arrowroot starch could have promising industrial applications.

In stalk of red hot pepper (<em>Capsicum annuum</em> L.) with 0.25 mm, 0.5 mm and 1.0 mm particle sizes, the quantities of nutritive and volatile compounds, bioactive capsaicin and carotenoids were determined. Furthermore, the stalk was characterized using TGA, DSC and FTIR spectroscopy. The influence of the particle size on the content of proteins, ash and cellulose is insignificant. Compared to 0.5 and 1.0 mm, stalk with 0.25 mm particle size was darker with a deeper yellow-brown color, and richer in microelements. Among the quantified volatile compounds, 6 were esters, 2 terpenoids, and 1 acid. The highest quantity of extract rich fats was obtained from stalk with 0.25 mm particle size by using ethanol, which is more efficient for capsaicin extraction, while <em>n</em>-hexane is efficient for extraction of carotenoids. Stalk with 0.25 mm particle size was characterized with a higher degradation temperature and residual weight.

ABSTRACT The bitter melon (Momordica charantia) is an exotic fruit that has adapted very well to the Brazilian soils, and can be found on practically all regions. Several advantages related to consumption of this fruit can be reported, highlighting its antifungal activity, reduction of glycemic indexes, and also due to the content of natural pigments, such as lycopene and β-carotene, making it promising as a functional food. Based on the demand for foods of this nature, this research aimed at the biometric characterization, physicochemical, bioactive compounds and the pulp and seeds’ antioxidant capacity of bitter melon, collected in the southwest region of Goias. The fruits were collected from plants inside a native vegetation area on Campus Rio Verde at the Instituto Federal Goiano, and the evaluations were carried out from October 2020 to April 2021. The fruits showed high variability in dimensions and weight, high concentrations of flavonoids, tannins, carotenoids, total phenolics and antioxidant capacity. According to results, the bitter melon can be used as a raw material to develop food formulations with functional characteristics and drugs potentially effective in the treatment of diabetes and diseases caused by oxidative processes.
