Structural analysis of rebaudioside A derivatives obtained by Lactobacillus reuteri 180 glucansucrase-catalyzed trans-α-glucosylation [PDF]

, 2017
The wild-type Gtf180-ΔN glucansucrase enzyme from Lactobacillus reuteri 180 was found to catalyze the α-glucosylation of the steviol glycoside rebaudioside A, using sucrose as glucosyl donor in a transglucosylation process.

Influence of Tapered‐End and Round‐End Bristle Designs on the Abrasive Enamel Wear Using Toothpastes With High Discrepancies in Abrasiveness

International Journal of Dental Hygiene, EarlyView.
ABSTRACT Purpose The aim of this in vitro study was to investigate the influence of bristle end design of toothbrushes and the relative enamel abrasivity (REA) of used toothpaste on the resulting abrasive enamel wear. Materials and Methods A total of 160 bovine enamel samples were allocated into eight groups (n = 20) and surface topography was recorded

Revisiting the Molecular Roadmap for Sugar Crops: Genome Reading, Trait Writing and Variety Redesigning

Plant Biotechnology Journal, Volume 24, Issue 9, Page 5013-5040, September 2026.
ABSTRACT Sugar crops, including but not limited to sugarcane, sugar beet, sweet sorghum and stevia, are major sources of sugar production in the world. However, conventional breeding approaches, limited by long breeding cycles, low efficiency and restricted capacity to improve complex traits in sugar crops, are increasingly insufficient to address the ...

Selective synthesis of rebaudioside M2 through structure-guided engineering of glycosyltransferase UGT94D1

Frontiers in Bioengineering and Biotechnology
Rebaudioside M2 (Reb M2), a novel steviol glycoside derivative, has limited industrial applications due to its low synthetic yield and selectivity. Herein, we identify UGT94D1 as a selective glycosyltransferase for rebaudioside D (Reb D), leading to the ...

Dynamic Sensory Profile of Functional Ice Cream Containing Freeze‐Dried Beetroot and Mango: Effects of Sweetening Systems and Brazil Nut Oil Incorporation

Journal of Sensory Studies, Volume 41, Issue 4, August 2026.
ABSTRACT This study developed a functional ice cream using freeze‐dried natural ingredients (beetroot and mango) and Brazil nut oil, incorporated in free and microencapsulated forms, and evaluated the effects of different sweetening on sensory perception through Time‐Intensity (TI), Temporal Dominance of Sensations (TDS), and Check‐all‐that‐Apply (CATA)
