Study of intermolecular interactions present in ternary mixtures containing sugar alcohol and choline chloride at different temperatures

Abstract

Artificial sweeteners also called non-calorific sweeteners are gaining popularity due to their sweet taste and metabolically inert nature. A lot of chemically designed artificial sweeteners are available in food industry. A type of artificial sweeteners is sugar alcohol, which have been used various food items and hence occupying a large place in food sector as well as in pharmaceutical industries. Erythritol, a sugar alcohol has been used in the present study as one of the component of ternary mixture. Other important constituent of the study is choline chloride. Choline is a primary metabolite that provides methyl groups required for the process of metabolism. Choline is key component that is utilized in the synthesis of two vital cell membrane phospholipids: phosphatidylcholine and sphingomyelin. Being a neurotransmitter, it also play an important role in balancing mood, memory and intelligence. To study the solvation behavior and collecting information regarding chemoreception, measurement of volumetric and acoustic properties of erythritol with choline chloride have been reported in this paper. By using the raw data of density and ultrasonic velocity measured by DSA 5000 of sound, different apparent molar properties of an non calorific sweetener (erythritol) have been computed for binary mixtures of different concentrations with water and ternary mixtures with choline chloride at different temperatures. Furthermore, other useful parameters for solvation have also been calculated like limiting apparent molar expansion, Eϕ0, specific volume, vϕ, hydration numbers etc. The obtained results have been discussed for interactional behavior related to structure changes in the studied systems.
