Combining eutectic solvents and pressurized liquid extraction coupled in-line with solid-phase extraction to recover, purify and stabilize anthocyanins from Brazilian berry waste

Stability of anthocyanins from red grape skins under pressurized liquid extraction and ultrasound-assisted extraction conditions.

The stability of anthocyanins from grape skins after applying different extraction techniques has been determined. The following compounds, previously extracted from real samples, were assessed: delphinidin 3-glucoside, cyanidin 3-glucoside, petunidin 3-glucoside, peonidin 3-glucoside, malvidin 3-glucoside, peonidin 3-acetylglucoside, malvidin 3-acetylglucoside, malvidin 3-caffeoylglucoside, pe...

On-line Combinations of Pressurized Hot-Water Extraction and Microporous Membrane Liquid–Liquid Extraction with Chromatography

298 Introduction Environmental and biological analyses are especially challenging for the analyst because sample matrices tend to be very complex and the analytes are present at very low levels. Selective and sensitive methods are needed for both sample preparation and analysis. Typically, extraction and clean-up are needed in the sample preparation, and the analyses are performed by chromatogr...

Development of Homogeneous Liquid-Liquid Extraction in Combination with Dispersive Liquid-Liquid Microextraction Based on Deep Eutectic Solvents for the Extraction and Assessment of Phytosterols in Animal Cream Samples using Gas Chromatography Equipp

Background and Objectives: Food quality and safety control is an important part of the public health assessment of food adulteration has been a key issue in recent years. Cream is a product containing milk fat and is one of the most expensive and widely consumed edible fats, which is often targeted for cheating by mixing various vegetable oils with natural milk fats. A way to detect this type o...

Uranium Extraction from Solid Waste as Nitrate Complex with D2EHPA, TOPO and their Synergistic Mixture

Pressurized liquid extraction and quantification of anthocyanins in purple-fleshed sweet potato genotypes

Analysis of anthocyanins responsible for the purple flesh color is important for breeding programs and development of value-added products. This study aimed to optimize the conditions for anthocyanin extraction from purple-fleshed sweet potatoes (PFSP) using pressurized-liquid extraction (PLE) method and quantify anthocyanins in various genotypes. Freeze-dried powders of PFSP genotypes were ext...
