Diets with a high sodium chloride (NaCl) intake are indicated by doctors to be a factor responsible for causing cardiovascular disease. This has led to the search for NaCl substitutes used to prepare meals and process industrialized products, resulting in the food industry using new compounds. In this context, flavor enhancers appear to be able to maintain the sensory characteristics of food and reduce the amount of NaCl used. Substituting NaCl with other light commercial salts may also represent an alternative to reducing its consumption. Thus, it is of great importance to have a sensitive, portable, reliable, and costeffective sensors for monitoring salt and flavor enhancers. For that reason, developing methodologies and devices able to chemically analyze salts and capable of establishing a relationship with human taste perception has become relevant for quality control and product development. In this context, this study proposes developing and applying an e-tongue system that can analyze aqueous solutions containing different concentrations of flavor enhancers (monosodium glutamate, disodium guanylate and disodium inosinate), light commercial salts and NaCl. The etongue comprised four gold interdigitated electrodes (IDEs) modified with layer-by-layer films of copper tetrasulfonated phthalocyanine (CuTsPc), polyaniline (PANI), reduced graphene oxide (rGO), poly(allylamine hydrochloride) (PAH) and silver nanoparticles (AgNPs) with different architectures. Data were statistically analyzed using principal component analysis (PCA). The e-tongue system proved to be efficient for identifying and discriminating flavor enhancers and commercial salts at different concentrations and is a possible alternative for quality control analysis and product development in the food industry.

Plants can be attacked by a wide variety of herbivores. Thus, developing protective mechanisms for resistance against these agents is an advantage for survival and reproduction. Over the course of evolution, many resistance mechanisms against herbivory have been developed by the plants. Induced direct and indirect resistance mechanisms can manifest in plants after herbivore attack. The two-spotted spider mite Tetranychus urticae is not a pest of maize crops (Zea mays), despite being reported infesting plants that may have resistances against this herbivore. We tested the hypothesis that maize plants would be able to induce direct resistance against T. urticae after, evaluating the effect of T. urticae infestation in maize plants on the development and reproduction of conspecifics. We tested induced direct resistance performing infestation and measuring biological parameters upon a second infestation. Maize plants, 40 days after sowing, were divided into two groups: 30 not infested by T. urticae (clean plants clean) and, 30 infested by the spider mite. Infestation of maize plants by T. urticae reduced the conspecific female adult survival. However, no change in the survival of immature or reproduction was observed. These results suggest the induction of induced direct resistances in maize by T. urticae. This is first report of direct resistance induction in Z. mays by the two-spotted spider mite T. urticae. |
