Article Abstract
This work aimed to study the effect of defatting via the mixture of n-hexane and ethanol under different volume ratio on the changes of structural characteristics, functional properties and volatile compounds of Tenebrio molitor larvae protein (TMLP). The results showed that 1:0.6 vol ratio of n-hexane to ethanol rendered the highest defatting rate (P < 0.05), as well as led to the highest EAA/AA contents, sulfhydryl contents, surface hydrophobicity, solubility, water/oil holding capacities and emulsifying properties of TMLP (P < 0.05). However, higher volume ratio of n-hexane to ethanol led to negative impacts on functionalities of TMLP. Moreover, the contents of aldehydes and hydrocarbons which rendered off-flavour to TMLP significantly decreased with the increasing volume ratio of n-hexane to ethanol (P < 0.05), while the contents of pleasure flavour (hydrocarbons and ester compounds) were obviously enhanced. This study provides an eco-friendly defatting method on the processing of TMLP with superior quality attributes.

The enantiomeric purity of Finerenone (FIN), a novel therapeutic for chronic kidney disease (CKD), is a critical quality attribute for ensuring patient safety. This study reports the first chiral HPLC method for the simultaneous determination of FIN and its enantiomer, developed and validated using a rigorous analytical quality by design (AQbD) framework. The method employs a CHIRALPAK AD-H column with an isocratic mobile phase of n-hexane: ethanol (62:38, v/v).
