Neotame is a dipeptide methyl ester derivate. Its chemical structure is N-[N-(3,3dimethylbutyl)-L-α-aspartyl]-L-phenylalanine 1-methyl ester. It is intended for use in food as a sweetener and flavour enhancer. Neotame has a sweetness factor approximately 7000 to 13000 times greater than that of sucrose and approximately 30 to 60 times greater than that of aspartame, depending upon the food appl...
Objectives: The aim of this study was to establish a prediction system for taste sense according to questionnaire surveys about dietary background. This study is a follow-up to a previously published Previous Article. Research Methods & Procedures: A total of 63 healthy Japanese participants, aged 20–28 years, who did not have smoking and drinking alcohol habit, were surveyed. Questionnaires ab...
The reported effects of temperature on sweet taste in humans have generally been small and inconsistent. Here, we describe 3 experiments that follow up a recent finding that cooling from 37 to 21 °C does not reduce the initial sweetness of sucrose but increases sweet taste adaptation. In experiment 1, subjects rated the sweetness of sucrose, glucose, and fructose solutions at 5-41 °C by dipping...
Literal language talks in a higher level than common language, everyone doesn’t have the ability to speak on literal language. There is question that how uncommonly speaking, this uncommon speaking highest quality of art. These percepts aesthetic literature by reader and Gitanjali its best example.

Taste evaluation technology has been developed by several methods, such as sensory tests, electronic tongues and a taste sensor based on lipid/polymer membranes. In particular, the taste sensor can individually quantify five basic tastes without multivariate analysis. However, it has proven difficult to develop a sweetness sensor, because sweeteners are classified into three types according to ...
Responses to brazzein, 25 brazzein mutants and two forms of monellin were studied in two types of experiments: electrophysiological recordings from chorda tympani S fibers of the rhesus monkey, Macaca mulatta, and psychophysical experiments. We found that different mutations at position 29 (changing Asp29 to Ala, Lys or Asn) made the molecule significantly sweeter than brazzein, while mutations...
Human desire for sweet taste spans all ages, races, and cultures. Throughout evolution, sweetness has had a role in human nutrition, helping to orient feeding behavior toward foods providing both energy and essential nutrients. Infants and young children in particular basemany of their food choices on familiarity and sweet taste. The low cost and ready availability of energycontaining sweetener...
