Assessing the Impact of Vegan Toothpastes on Enamel Color Change and Surface Properties

Journal of Esthetic and Restorative Dentistry, Volume 37, Issue 9, Page 2104-2115, September 2025.
ABSTRACT Objective To evaluate color (ΔE00) and whiteness index (ΔWID) changes, surface hardness loss (SHL), roughness (Ra), mineral content, and morphology of enamel brushed with vegan toothpastes. Methods Enamel blocks (n = 10/group) were stained with black tea (T0) underwent 15.000 (T1) and 30.000 (T2) toothbrushing cycles with: (n = 10): (AS ...

Viabilidad de polen e irregularidades meióticas en una colección de stevia rebaudiana (Bertoni) Bertoni cultivada en Tucumán, Argentina [PDF]

, 2018
Stevia rebaudiana (Bertoni) Bertoni (2n=2x=22) (Asteraceae family) is a species of economic value due to the presence of steviol glycosides in leaves -mainly stevioside and rebaudioside A- which are non-caloric sugars.

Trans-α-glucosylation of stevioside by the mutant glucansucrase enzyme Gtf180-ΔN-Q1140E improves its taste profile [PDF]

, 2019
The adverse health effects of sucrose overconsumption, typical for diets in developed countries, necessitate use of low-calorie sweeteners. Following approval by the European Commission (2011), steviol glycosides are increasingly used as high-intensity ...

Green and Sustainable Synthesis of Silver and Gold Nanoparticles: A Stevia Leaf Extract Approach

Food Science &Nutrition, Volume 13, Issue 8, August 2025.
Stevia extracts offer a novel and environmentally friendly method for synthesizing silver (AgNPs) and gold (AuNPs) nanoparticles. The synthesized nanoparticles displayed characteristic surface plasmon resonance (SPR) in specific ranges and were confirmed to be spherical and well‐dispersed via TEM imaging.

Effect of LED Light Source on Steviol Glycosides, Pigments, and Ascorbic Acid Concentration in Leaves of Stevia rebaudiana (Bertoni)

Acta Universitatis Cibiniensis. Series E: Food Technology
This study concerns the effects of the light source on the steviol glycosides concentration in Stevia rebaudiana (Bertoni) leaves. In addition, the concentration of chlorophylls, carotenoids, vitamin C, and proteins was determined.

Update: Enzymatische Synthese für industrielle Anwendungen

Angewandte Chemie, Volume 137, Issue 27, July 1, 2025.
Die Biokatalyse hat sich zu einer nachhaltigen und wettbewerbsfähigen Alternative zur herkömmlichen chemischen Synthese entwickelt und ermöglicht die enzymbasierte Herstellung nicht nur von chemischen Grundstoffen, sondern auch von (nicht natürlichen) Aminosäuren, (seltenen) Zuckern und synthetischen Nukleotiden.

Investigating perception and liking of non-nutritive sweeteners in individuals representing different taste receptor genotypes [PDF]

, 2018
This study investigates whether variations in taste receptor genotypes account for differences in perception and liking of the non-nutritive sweeteners sucralose and Rebaudioside A (RebA).

An Update: Enzymatic Synthesis for Industrial Applications

Angewandte Chemie International Edition, Volume 64, Issue 27, July 1, 2025.
Biocatalysis has become a sustainable and cost‐competitive alternative to established chemical synthesis, enabling the enzyme‐based production of not only commodity chemicals but (non‐natural) amino acids, (rare) sugars, as well as synthetic nucleotides.

Scientific Opinion on the safety of steviol glycosides for the proposed uses as a food additive

EFSA Journal, 2010
Steviol glycosides in the present evaluation are mixtures of steviol glycosides that comprise not less than 95% of stevioside and/or rebaudioside A. Stevioside as a sweetener was evaluated by the SCF in 1984, 1989 and 1999.

Solubility of Stevioside and Rebaudioside A in water, ethanol and their binary mixtures

International Journal of Food Studies, 2016
In order to investigate the solubility of Stevioside and Rebaudioside A in different solvents (ethanol, water, ethanol:water 30:70 and ethanol:water 70:30), supersaturated solutions of pre-crystalized steviol glycosides were maintained at different ...
