This is an introduction to a food analysis case study by a specialist in analysis. This time, we will reveal the secrets of chocolate's deliciousness through thermal analysis and viscoelasticity.

This time, TA Instruments introduces a differential scanning calorimeter called "DSC" and a viscometer known as a "rheometer." In this article, we will clearly explain the deliciousness of chocolate, a familiar food, focusing on the measurement image model related to tempering. ◆ Chocolate Melting and Viscoelasticity Measurement Chocolate has a hardness that allows it to be held in hand before eating, but it mysteriously melts sweetly as soon as it enters the mouth. This characteristic is imparted by a process called "tempering." We investigated the differences that arise from tempering using a rheometer. ◆ The Importance of Tempering and Cocoa Butter Crystal Forms for Delicious Chocolate Did you know that chocolate has as many as six different crystal structures? By controlling these crystal structures during "tempering," we can create a pleasant mouthfeel and shine. We examined the differences that arise from tempering using a DSC.

This is an introduction to a case study of lubricant analysis by a specialist in analysis. This time, we will clarify the shear rate and temperature dependence of frictional behavior using a rheometer.

This time, TA Instruments introduces a viscoelastic measurement device called the "Rheometer; DHR." In this article, we prepared two types of lubricants and evaluated the friction coefficient measurements of each lubricant, as well as their dependence on shear rate and temperature. ◆ Evaluation of the change behavior of the friction coefficient of lubricants at room temperature The friction measurement accessory of our rheometer (DHR) consists of four metal balls, allowing for stable friction coefficient measurements. We evaluated two types of lubricants and compared their friction coefficients. ◆ Joint evaluation of friction coefficient changes under high temperature and high shear rate The previous measurements were conducted at room temperature, but when used in the field, it is necessary to consider conditions such as high temperatures and high shear rates. This time, we evaluated how the friction of the lubricants changes under conditions of 180°C and 0.1 to 100 mm/s, and which lubricant is more useful as a lubricant, referencing the Stribeck curve.

This is an introduction to case studies of pharmaceutical analysis by a specialist in analysis. This time, we will cover the pharmacokinetics of suppositories and the viscoelastic measurement of hair wax.

TA Instruments handles a device called a "rheometer," which measures viscoelasticity. In this article, we will introduce examples of viscoelasticity measurements for familiar pharmaceutical cosmetics, specifically suppositories and hair wax, along with an easy-to-understand model of the measurement process. ◆ Softening Behavior of Suppositories in the Body For suppositories that are injected and used in the body, the viscoelasticity at storage temperature and body temperature significantly affects product performance. Therefore, we conducted temperature-dependent viscoelasticity measurements on two types of suppository samples. ◆ Application Feel of Hair Wax and Creep Recovery Test It is common to see a wide variety of hair waxes displayed, tailored to different hair types and desired hairstyles. When you pick them up, each has a different feel, suggesting variations in viscoelasticity. Using a rheometer, we can quantitatively evaluate basic viscoelastic indicators such as elasticity and viscosity. Additionally, as will be introduced below, we can assess the stretchability and holding power of hair wax through a measurement mode that mimics the application process on hair (creep recovery test).
