ABSTRACT Recent reports suggest that enhancement of memory performance while chewing gum is a fairly robust phenomenon. The processes underlying the effect are not known, but may involve glucose delivery, context-dependent effects and arousal mechanisms amongst others. This brief commentary outlines the main findings from these studies and raises some issues regarding interpretation, methodology and future research directions.

    ABSTRACT: Chewing of gum contributes to the maintenance of oral health. Many oral diseases, including caries and periodontal disease, are caused by bacteria. However, it is unknown whether chewing of gum can remove bacteria from the oral cavity. Here, we hypothesize that chewing of gum can trap bacteria and remove them from the oral cavity. To test this hypothesis, we developed two methods to quantify numbers of bacteria trapped in chewed gum. In the first method, known numbers of bacteria were finger-chewed into gum and chewed gums were molded to standard dimensions, sonicated and plated to determine numbers of colony-forming-units incorporated, yielding calibration curves of colony-forming-units retrieved versus finger-chewed in. In a second method, calibration curves were created by finger-chewing known numbers of bacteria into gum and subsequently dissolving the gum in a mixture of chloroform and tris-ethylenediaminetetraacetic-acid (TE)-buffer. The TE-buffer was analyzed using quantitative Polymerase-Chain-Reaction (qPCR), yielding calibration curves of total numbers of bacteria versus finger-chewed in. Next, five volunteers were requested to chew gum up to 10 min after which numbers of colony-forming-units and total numbers of bacteria trapped in chewed gum were determined using the above methods. The qPCR method, involving both dead and live bacteria yielded higher numbers of retrieved bacteria than plating, involving only viable bacteria. Numbers of trapped bacteria were maximal during initial chewing after which a slow decrease over time up to 10 min was observed. Around 108 bacteria were detected per gum piece depending on the method and gum considered. The number of species trapped in chewed gum increased with chewing time. Trapped bacteria were clearly visualized in chewed gum using scanning-electron-microscopy. Summarizing, using novel methods to quantify and qualify oral bacteria trapped in chewed gum, the hypothesis is confirmed that chewing of gum can trap and remove bacteria from the oral cavity.

    ABSTRACT: The food industry is one of the most important branches of the national economy in Italy and in the European Union in general, playing a central role for the processing of agricultural raw materials and food supply. This industry is traditionally regarded as a sector with low research intensity; notwithstanding, innovations are recognized as an important instrument for companies belonging to the food industry in order to stand out from competitors and to satisfy consumer expectations. In this regard, functional foods play an outstanding role, as demonstrated by their increasing demand derived from the increasing cost of healthcare, the steady increase of life expectancy, and the desire of older people for improved quality of their later years. The main target of this paper is to analyze the state of the art on functional foods. For this purpose, a review of extant literature is presented. Specific emphasis is laid on the definition and the main examples of functional food. The paper concludes with comments on future trends.

    ABSTRACT: A water-based sucrose solution at subthreshold concentration (1 g/L) and pure water were used to evaluate the discriminative ability of nontrained judges to perform a two-alternative forced-choice (2AFC) test after the use of chewing gum for different periods of time. Three types of chewing gum were evaluated: CF, fruit-flavored caloric (sweetened with sucrose/dextrose); NF, fruit-flavored noncaloric (sweetened with Sorbitol/Xylitol); and NC, unsweetened, unflavored, unsoftened gum base. Two fixed times and four time classes were selected for the chewing times studied at 2, 5, 10–19, 20–29, 30–39 and ≥40 min. While the control group (no gum) was not able to consistently identify the sweet solution, judges chewing NC, NF and CF were able to do so (α = 0.05) after 5, 10 and 30 min of chewing, respectively. An increase in salivary flow rate, salivary pH and perceptive memory elicited by the gustatory and mechanical stimulation involved in the act of chewing are suggested as possible mechanisms behind the observed effect.PRACTICAL APPLICATIONSDiscriminative sensory analytical methods must be able to reliably detect and quantify differences between samples. Any new test protocol or addition to it, which is able to improve the performance and sensitivity of sensory judges as individuals or as a group, helps in reaching this goal. From a practical point of view, ensuring that a test protocol renders results comparable with those produced by the most sensitive individuals in a given population guarantees the validity and usefulness of the conducted tests and their results. The proposed use of chewing gum as a preparative step in discriminative sensory test protocols is an attempt to finding a method able to increase the discriminative ability of sensory taste panels composed of nontrained judges.
