A process for removing lactic acid from an aqueous lactic acid-containing magnesium chloride solution, the weight ratio of magnesium chloride to lactic acid in the aqueous lactic acid-containing magnesium chloride solution being at least 1:1, the process including the steps of subjecting the aqueous lactic acid-containing magnesium chloride solution to an evaporation step, resulting in the formation of a slurry of MgC12.MgL2.4H2O in an aqueous magnesium chloride solution, then subjecting the slurry to a solid-liquid separation step, to separate the solid MgC12.MgL2.4H2O from the aqueous magnesium chloride solution, resulting in the removal of lactic acid from the aqueous lactic acid-containing magnesium chloride solution in the form of MgC12.MgL2.4H2O. The process makes it possible to efficiently remove lactic acid from aqueous lactic acid-containing magnesium chloride solutions, resulting in magnesium chloride solutions with a low lactic acid content which can be further processed as desired.

Proposed is a Geumhwagyu extract as an active ingredient. The Geumhwagyu extract of the present disclosure inhibits the differentiation of pre-adipocytes by inducing the degradation of CEBP-α and inhibits the expression of CEBP-α, PPARγ, Perilipin-1, Adiponectin, FABP4, etc., to suppress the accumulation of lipids in adipocytes. It can be easily used as a composition for preventing or managing obesity by inhibiting it and lowering the content of TG (Triacylglycerol) to show anti-obesity activity.

A method of separating and purifying a mixed stream of contaminated reclaimed polyethylene and contaminated reclaimed polypropylene is provided. The method comprises the steps of extraction, dissolution, settling, purification, and solvent separation to produce separate streams of purified recycled polyethylene and purified recycled polypropylene. Both separate streams are produced in the same production plant operating in swing mode, and have virgin-like optical properties.
