Discussion of Testers and Test Procedures

Development, Physicochemical Properties, and Antibacterial Activity of Propolis Microcapsules

“…Microcapsules prepared from acacia gum and β-CD containing a large number of hydrophilic groups will exhibit better wettability, which may contribute to their solubility [66]. Flowability is a distinguishing trait but not an inherent and comprehensive property of powder [67], and flowability was related to the equipment and the testing method used to describe the complex behavior of powder when it was mobilized or subjected to stress [68,69]. Flowability also has a major influence on the processability of powder [69].…”

Flowability also has a major influence on the processability of powder [69]. The HR of the propolis microcapsule was 1.23, indicating that the flowability was fair [70].…”

Multivariate correlation of PolyArylEtherKetone powder properties for additive manufacturing and a method for predicting spreading in polymer powder bed fusion

“…Classification of powder tests based on the results given: single value or multivalue results. [12].…”

“…Powder flow can be characterised by multiple methods [12] which fall into two main categories: tests which produce a single value such as Angle of Repose, or tests which produce multiple values such as Jenicke's Shear test [13] (see Table 1). Leturia et al, [14] and Tay et al, [15] concluded it is desirable to use a characterisation method which mimics the application, yet powder flow cannot be accurately quantified with a single indicator.…”

Dry fractionation of oil-rich legumes for recovery of functional protein ingredients

“…A metal impeller ST36-2V-10/PCC (Anton Paar, Graz, Austria) with two rectangular-shaped blades (36 mm x 10 mm) was used to measure the powders' resistance to flow. The measured torque values are used for the semi-quantitative comparison of the powder flowability (Salehi et al, 2017;Schulze, 2008). For each measurement 30 g of flour was added to the powder flow cell and briefly stirred manually to mix the sample, using a spatula.…”
