Melting point, entropy of melting and heat capacity of melting are required for the calculation of the ideal solubility of a solid solute via the Clausius-Clapyron equation. This article reviews the published approximations of estimating entropy and heat capacity of melting. By comparing the available experimental results to calculated values the authors attempt to identify the best estimation of the ideal solubility and crystal-liquid fugacity ratio for organic compounds.

Blackberry can be considered a source of phenolic compounds with antioxidant properties, especially anthocyanins, which are responsible for the attractive color of the juice. However, blackberry juice quality can be reduced under severe heat treatments, resulting in darkened color and altered taste. Membrane separation processes are an alternative for the clarification and concentration of fruit juices, with advantages as the maintenance of the nutritional, sensory, and functional characteristics of the product.

In this study, we describe the development of hydrogel formulations composed of micelles loading two natural antioxidants-resveratrol and rutin-and the evaluation of the effect of a by-product on the rheological and textural properties of the developed semi-solids. This approach aims to associate the advantages of hydrogels for topical administration of drugs and of lipid micelles that mimic skin composition for the delivery of poorly water-soluble compounds in combination therapy. Biomimetic micelles composed of L-α-phosphatidylcholine loaded with two distinct polyphenols (one non-flavonoid and one flavonoid) were produced using hot shear homogenisation followed by the ultrasonication method.

Considering the outstanding advantages including abundant resources, structure-performance designability, impressive mechanical strength, and 3D network structure-forming ability, cellulose is an ideal material for encapsulating bioactive ingredients. Due to its low solubility in water, large-scaled morphology and poor flexibility, cellulose is unsuitable for the construction of carriers. Consequently, the majority of cellulose is employed following physical or chemical modification.
