From needles to pattern in food quality determination

Abstract

How can food quality influence pattern of CuCl2 crystals?

Influence of dewetting on the crystallization behavior of CuCl₂ in the presence of BSA during evaporation in a Petri dish

“…Beckmann [9] and Leray [10] worked on the growth velocity, Leray [11] on the dendritic growth and a model for the profile of the solution, Gallinet [12] on the formation of a monolayer of B ovine S erum A lbumin (shortly BSA) as additive including the process of dewetting and Holleman [13] and Busscher [14] on the evaporation profile. Busscher [15] defined a minimum set of physical parameters to research the basic processes during evaporation and crystallization that influence the overall structure of the DCC crystallization patterns, with and without the addition of additives.…”

“…1), wheat [17] Fig. 5, and to a lesser extent with carrots [14, 15], as additives, but is absent for milk [16]. To study this process in more detail, BSA was chosen as additive as it shows comparable limitations in the coverage of the surface [12] but is chemically and physically very well defined (e.g.…”

Differentiation of organic and non-organic winter wheat cultivars from a controlled field trial by crystallization patterns

“…Standardized crystallization with additives consists of sample preparation, crystallization, data evaluation and multivariate statistical analysis. Crystallization patterns, which are characteristic for the sample material investigated, emerge when an aqueous cupric chloride (CuCl 2 .2H 2 O) solution is crystallized on a glass dish in the presence of a plant extract or molecule . The patterns are evaluated by computer‐based image analysis of texture or structure variables .…”

Phase-Transition-Induced Pattern Formation Applied to Basic Research on Homeopathy: A Systematic Review

“…2 Since PTPF methods show an extreme sensitivity to even slightest differences in the departing solution, they were applied for the analysis of samples deriving from living organisms in terms of their health state. Methods based on PTPF have been used as diagnostic approaches in human medicine (PTPF methods applied to blood and other bodily fluids 10 ), veterinary medicine (PTPF methods applied to bodily fluids from animals 11,12 ), and as food quality analysis methods (PTPF methods applied to extracts of plants and other food products 13 ).…”
