“…This was due to the mobility of electric charge due to the presence of hydroxyl and carbonyl groups present in the modified starch. This result is higher than those reported in the literature for starch (Arrieta, Jaramillo, & Palencia, 2015). Therefore, one of the possible applications of the modified starch would be as a semiconductor material of electricity.…”

Modification of banana starch (Musa paradisiaca L.) with BHET Highlights• The chemical modification of banana starch with BHET caused changes in the morphology of its granules. • • Terephthalate and glycol groups were mainly bound to the carbon 6 of the starch. • • The modified starch showed a lower thermal stability respect to the pristine starch and further increased the amorphous regions. • • The films obtained from the modified starch had a higher electrical conductivity than the native starch.

Recently developed biopolymers can contain lead due to contamination from the origin of the material used to make them. A method for determining the presence of lead is proposed, using GF-AAS in thermoformed and biodegradable flexible films and flour and starch samples from Cassava. Acid digestion with reflux was optimized and the statistical quality parameters were standardized. The graphite furnace heating program was adjusted through pyrolysis and atomization curves. The working range was from 2.0 to 7.0 μg/L, with limits of detection and quantification of 0.618 and 1.853 μg/L, respectively. The precision was evaluated using intermediate precision and repeatability of the method, which showed standard deviations of less than 4.70% and 4.36%, respectively. The percentage of recovery ranged from 94.8% to 106.5%. The results obtained support the suitability of the method for determining the presence of lead. Lead concentrations were below 1 mg/Kg, indicating that these polymers can be used for food containers.

A Review of sample preparation and techniques used to determine Cadmium content in flexible films and biodegradable thermoformed products based on cassava. All determinations have been made using atomic absorption spectroscopy. The presence of this element in these matrices can be harmful if the maximum tolerated quantities are not complied by. The presence of Cadmium may be due, among other aspects, to the fact that it is present in the raw material, in industrial discharges or because it is found naturally. Its determination is an important parameter that needs to be considered as a good alternative for packaging.
