Quality characteristics of field muskmelon seed oil extracted by different processes

Abstract

Field muskmelon seeds contain plenty of oil. However, its potential as vegetable food oil has not been explored comprehensively. This study used three different processes, cold extrusion (CE), coasting followed by cold extrusion (R-CE), and supercritical fluid extraction (SFE), for the extraction of field muskmelon seed oil (FMSO) and studied its quality characteristics such as color, fatty acid composition, and volatile components. The study found that FMSO is abundant in unsaturated fatty acids (UFA) and has a pleasant aroma. Gas chromatography-mass spectrometry (GC-MS) revealed that FMSO contains five main fatty acids, palmitic (11.

Extraction methods of melanoidins and its potential as a natural pigment

“…Moreover, ACE, PTB-1B, and trypsin inhibitory activities were also augmented. SFE is a new, clean, efficient and green separation technology, which integrates the advantages of two chemical unit operations (distillation and liquid-liquid extraction) and easily diffuses through solid materials (Zhang & Du, 2022). In addition, Supercritical carbon dioxide is usually employed as a ideal solvent to assist extraction.In the experiment of Maran et al (2014), researchers used supercritical carbon dioxide extraction method to extract anthocyanins and phenolic compounds from dried ginger fruit.The optimum extraction conditions were found through optimization, The obtained total anthocyanin content and phenol content were 1143.051 ± 1.58 mg/100 g and 231.28 ± 0.76 mg/100 g, respectively.…”
