Comparison of physicochemical properties and oxidative stability of microencapsulated perilla oil powder prepared by freeze-drying and spray-drying

A comprehensive review on nutritional, nutraceutical, and industrial perspectives of perilla (Perilla frutscens L.) seeds – An orphan oilseed crop

“…Researchers have explored innovative methods like freeze-drying and spray-drying for microencapsulation of PSO to enhance oxidative stability [ 6 ]. Urea complexation combined with rapid preparative reversed-phase liquid chromatography has successfully isolated α-linolenic acid with high purity from PSO, while α-tocopherol has been identified as effective in reducing α-linolenic acid oxidation [ 56 ].…”

“…Perilla frutescens (L.) Britton (2n = 40), commonly known as perilla, is an orphan oilseed crop native to East Asia, particularly China, Korea, Japan, India, and Thailand. Belonging to the family Lamiaceae, subfamily Lamioideae, tribe Saturejeae, and subtribe Perillinae, this annual herbaceous crop bears small self-pollinating flowers and brown fruits containing black to white or various shades of grey or brown seeds [ [4] , [5] , [6] ]. The seeds contain an oil content ranging from 30 % to 45 %.…”
