“…[44] The difference in the E of potato and arracacha biofilms having the same concentration of starch and glycerol is therefore probably due to the amylose and amylopectin molecular weight and the amylopectin chain length. [46] Tables 3 and 4 show the estimated regression coefficients and the analysis of variance, as well as the quadratic model for the whiteness, TV, and E of the biofilms. For potato starch, only the linear effect of starch concentration for whiteness was not significant (p > 0.05).…”

Arracacha starch and potato starch are alternatives to synthetic polymers as starting materials for the production of biofilms. Herein, we determined the optimal concentrations of glycerol and potato or arracacha starch to obtain biofilms with high whiteness, transparency value (TV), and elastic modulus (E). Central composite design with the response surface methodology and desirability function are used to optimize the concentration of starch and glycerol. The biofilms are formed by the casting method using gelatinized starch suspensions (3-5%) mixed with glycerol (1-3%). The solubility and swelling power differences of the potato and arracacha starches indicated differences in the starch structures, which affected the properties of the biofilms. The potato and arracacha biofilms with the same starch and glycerol concentrations exhibited different TV and E. Linear effects, quadratics, and the interaction of the starch and glycerol have significant effects on the whiteness, TV, and E of the potato and arracacha biofilms (p < 0.05). The coefficient of variation for the obtained models is >0.98%. The optimal conditions determined using the desirability function are 5% starch and 1.02% glycerol for potato biofilms and 5% starch and 1% glycerol for arracacha starch biofilms.

“…2, están son de un color blanquecino transparente que van tiñéndose de amarillo con el aumento de la concentración de nanopartículas de plata. La coloración depende de la matriz usada en el polímero, por lo general los biopolímeros formados a partir de almidón de papa presentan inicialmente esta coloración [16,[18][19][20], pero la tendencia al amarillo en la coloración se debe a la presencia de las nanopartículas de plata tal y como se observa en [14,15].

This paper presents the study of the effect of the incorporation of biosynthesized silver nanoparticles on the properties of biodegradable films made from potato starch and its potential to be used as active material. Silver nanoparticles were manufactured by green route from grape residues and were added in the film gelatinization process at concentrations of 3% and 6% v/v. The silver nanoparticles were characterized by UV-Vis and FTIR spectroscopy, while the fabric films were characterized by their density and % moisture content. Active properties were characterized using water absorption kinetics and biodegradation by burial in soil. The integration of silver nanoparticles in biodegradable films made from potato starch was confirmed, confirming the effects on their physical characteristics and active properties depending on the percentage of AgNp, which can be used for the manufacture of active materials.

In the present study the experiment was conducted in the Department of Food Process TechnologyLab and Department of Food Safety and Quality Assurance Lab to synthesize bio plastic fromselected fruit peels (Banana and Orange peels) in different concentrations by the addition ofdifferent essential oils namely lime oil and clove oil which acts as a preservative and aroma agentwhich serves as potential alternative to the conventional plastic material. In the experimentbioplastic is made from banana and orange peels in different concentrations i.e., banana peels (100g), orange peel (100 g) and combination of banana (50 g) and orange peel (50 g). The Bioplastic made from orange peel was observed with some gaps as starch content in orange peel is less whencompared to banana peel. Bioplastic made from the combination of both peels in the concentrationof banana peel (50 g) and orange peel (50 g) was little bit stiff with some gaps and when tried withthe concentration of banana peel (70 g) and orange peel (30 g) bioplastic was obtained. Thesynthesized bioplastic was subjected to mould test, swelling test, solubility test, Biodegradable testand elongation test. On experiment the mould test revealed that it can be moulded into differentshapes like conventional plastic. Swelling test showed that there is a slight increase in weight ofthe bioplastic when soaked in water as a medium and this is a desirable result because most of theadditives are prepared by using organic solvents, certainly it will help in stabilize productsynthesis and development. From the solubility test it was revealed that none of the samples weresoluble in different mediums which shows that the bioplastic material prepared is stable.Biodegradability test showed that the obtained bioplastic is degradable within 15 days. Thebioplastic made with the combination of banana and orange peels showed more percentage ofelongation i.e., 20.4% where as the bioplastic made from banana peel showed 10% and from orangepeel showed 3% which indicates that the bioplastic synthesized from combination of fruit peelshas more strength compared to individual peels.
