Microencapsulation of Annatto Seed Extract: Stability and Application

Chemical Engineering Transactions, 2013
Annatto is the most widely used natural colouring in the food industry, although with a certain degree of difficulty in its applicability due to its lower stability when compared to synthetic colorants.

The plasticisation model of dye diffusion: Part 8

Coloration Technology, EarlyView.
Abstract Re‐evaluation using the Williams–Landel–Ferry equation, of exhaustion/rate of dyeing/fixation data previously reported for and acid dye, natural dye and two reactive dyes on three different types of silk substrate revealed that thermally activated dye diffusivity is governed by the thermally regulated structural relaxation times of the ...

Powdered hibiscus anthocyanin‐nanofibril complexes as natural colourants: Stability and application in yoghurt and soft candy

Coloration Technology, EarlyView.
Abstract The instability of anthocyanins limits their application as natural food colorants. This study aimed to enhance the stability of anthocyanins extracted from Hibiscus sabdariffa through copigmentation with protein nanofibrils produced from pea, rice, gluten and whey isolates. Linear and curly nanofibril structures were prepared and incorporated

Investigation into the dyeing of pre‐mordanted & cationised woven cotton fabric with cochineal

Coloration Technology, EarlyView.
Abstract Dyeing cotton with natural dyes typically requires the pre‐application of a mordant, which enables better dye exhaustion from solution and ‘fixes’ the colorant in the fibre. The most common application system for cellulosic fibres is a combination of plant‐derived tannins and aluminium salts, such as aluminium sulphate.

Comparative evaluation of reactive dye structures on colour strength enhancement in caustic‐treated regenerated bamboo fabrics

Coloration Technology, EarlyView.
Abstract Regenerated bamboo fibres offer a sustainable alternative to conventional cellulosic materials; however, achieving high and reproducible colour strength with reactive dyes may depend on both fibre accessibility and dye molecular architecture.

Ultra‐High‐Speed Sintering of 3.5Y‐TZP Zirconia: Time Reduction Without Compromising Translucency

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives To assess, firstly, the impact of three sintering speeds on translucency and grain size of 3.5Y‐TZP zirconia (Katana HT) across clinically relevant thicknesses, and secondly, the effect of thermocycling on translucency. Materials and Methods Disc specimens were fabricated at six thicknesses (0.7–2.0 mm) and sintered using SLOW (7 h),

Diet‐Induced Chromogenic Challenge Model for Additively Manufactured Tooth‐Colored Dental Resin Materials

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives This study aimed to evaluate the color stability of glaze‐coated 3D‐printed resin materials stored in different nutritionally beneficial smoothies that are commonly consumed. Methods Disc‐shaped (27 × 1 mm) specimens were fabricated from tooth‐colored 3D‐printed dental resins with different indications: Arma Resin (Group A ...
