Development and Characterization of a Biodegradable PLA Food Packaging Hold Monoterpene–Cyclodextrin Complexes against Alternaria alternata

The fungi of the genus Alternaria are among the main pathogens causing post-harvest diseases and significant economic losses. The consumption of Alternaria contaminated foods may be a major risk to human health, as many Alternaria species produce several toxic mycotoxins and secondary metabolites. To protect consumer health and extend the shelf life of food products, the development of new ways of packaging is of outmost importance. The aim of this work was to investigate the antifungal capacity of a biodegradable poly(lactic acid) (PLA) package filled with thymol or carvacrol complexed in β-cyclodextrins (β-CDs) by the solubility method. Once solid complexes were obtained by spray drying, varying proportions (0.0%, 1.5%, 2.5%, and 5.0 wt%) of β-CD–thymol or β-CD–carvacrol were mixed with PLA for packaging development by injection process. The formation of stable complexes between β-CDs and carvacrol or thymol molecules was assessed by Fourier-transform infrared spectroscopy (FTIR). Mechanical, structural, and thermal characterization of the developed packaging was also carried out. The polymer surface showed a decrease in the number of cuts and folds as the amount of encapsulation increased, thereby reducing the stiffness of the packaging. In addition, thermogravimetric analysis (TGA) revealed a slight decrease in the temperature of degradation of PLA package as the concentration of the complexes increased, with β-CD–carvacrol or β-CDs–thymol complexes acting as plasticisers that lowered the intermolecular forces of the polymer chains, thereby improving the breaking point. Packages containing 2.5% and 5% β-CD–carvacrol, or 5% β-CD–thymol showed Alternaria alternata inhibition after 10 days of incubation revealing their potential uses in agrofood industry.

Tapete receptor de residuos en mingitorios

, Villa LĂ³pez, Jose Luis , Acevedo, Hector

La presente invenciĂ³n se refiere a un dispositivo, para baños pĂºblicos o privados, que capte los orines residuales que caen a nivel del suelo del mingitorio de pared, es un apoyo para mantener limpios los baños en el Ă¡rea de sanitizaciĂ³n. Consiste en un captador de pequeñas cantidades de orina que no caen en el mingitorio y un nĂºcleo absorbente de los mismos, que gracias a su disposiciĂ³n logra captar una mayor cantidad de lĂ­quidos, y evitar a su vez la salida de malos olores, ademĂ¡s de ser fĂ¡cil en su uso, ya que al estar conformado por cartuchos reemplazables e intercambiables es mĂ¡s sencilla y rĂ¡pida su limpieza.
