Thaumatin is a sweetener and flavor modifier commonly used in the food industry. Likewise, gum arabic is widely used as a food stabilizer and thickening agent. We report here that a powder mixture composed of 10% thaumatin and 90% gum arabic led to allergic symptoms in the upper airways in occupationally exposed individuals: four of eight workers of a chewing gum factory exposed to this powder mixture had pronounced rhinitis. A positive skin prick test result for pure thaumatin was obtained in…

Re‐evaluation of thaumatin (E 957) as food additive
Abstract The present opinion deals with the re‐evaluation of thaumatin (E 957) when used as a food additive. Thaumatin is a natural plant protein, consisting of thaumatin I and thaumatin II proteins
Plants as a source of natural high-intensity sweeteners: a review
TLDR
The plants described in this review are a source of natural highintensity sweeteners, which can be used in food and by the pharmaceutical industry in the future and some of these substances can also modify the taste, like changing sour into sweet taste.
Natural Sweeteners: The Relevance of Food Naturalness for Consumers, Food Security Aspects, Sustainability and Health Impacts
TLDR
The most important aspects of consumer’s perceptions of and attitudes to natural foods and in-depth research into natural sweeteners are addressed, including issues about their use and development as regards health impacts, food security and sustainability.
Identification of the Active Principle Conferring Anti-Inflammatory and Antinociceptive Properties in Bamboo Plant
TLDR
A protein, with an amino acid sequence similar to that of thaumatins, capable of repressing inflammation through downregulation of neutrophil recruitment and of decreasing hyperalgesia in mice is identified.

Cytopathology of the Nasal Mucosa in Smokers: A Possible Biomarker of Air Pollution?
TLDR
As yet, no significant relation between smoking habits and the incidence of nasal sinus squamous cell carcinomas has been demonstrated in contrast to the established relationship between smoking and carcinomas of the larynx and lungs, so it is conceivable that cytopathologic changes in the nasal mucosa could act as a biomarker reflecting similarChanges in the lower respiratory tract.

TLDR
The nature of basophil activation as an ex vivo challenge makes it a multifaceted and promising tool for the allergist, and it ought to precede challenge testing.
