Oils from fruit seeds and their dietetic and cosmetic significance

Abstract

Summary Plant-origin oils are an essential element of the diet, affecting the preservation of health, but also of significant importance for the care of skin and its appendages. Among fats of plant origin, oils from fruit seeds are an important group. They are a rich source of fatty acids, tocopherols, tocotrienols, carotenoids, flavonoids, phytosterols and other bioactive compounds that have positive effect in relation to specific functions of the human body. Fruit seed oils play an important role in health prophylaxis, because they prevent the development of diseases of civilisation, alleviate the effects of stress and slow down the ageing process of the body. Due to the beneficial effects on the skin, they are also used in cosmetology. In formulations of cosmetic preparations, plant oils are the basis for the administration of other active ingredients, but they are also used due to their biological properties. The article discusses in detail the composition, dietary and cosmetic importance of oil from the seeds of raspberries, blackcurrants, rose hips and grapes.

Chemical Composition and Antioxidant Properties of Oils from the Seeds of Five Apricot (<i>Prunus armeniaca</i> L.) Cultivars

“…Linoleic acid is recognized as one of the most important polyunsaturated fatty acids due to its healthpromoting properties in the case of various diseases, especially allergic, inflammatory and cardiovascular diseases 10,52 . Vegetable oils rich in unsaturated fatty acids also have a significant beneficial effect on the appearance and function of the skin 1,53,54 . Vegetable fats strengthen the skin protection barrier, promote restoration of the stratum corneum lipid layer, prevent transepidermal water loss TEWL , normalize sebaceous glands, reduce the negative effects of UV radiation on the skin, and prevent photoaging of the skin.…”

“…The RS is a source of oil having many functional constituents like phenolics, tocopherols, sterols, and essential fatty acids [6]. The RS oil (RSO) can be used as cosmetics and nutraceuticals [7]. It is also favorable in traditional medicine and clinical usages [8].…”

Bioactive Compounds for Skin Health: A Review

“…Owing to unsaturated fatty acids, which, alongside ceramides and cholesterol, are components of the intracellular cement, the skin can act as an effective barrier limiting TEWL, thus ensuring adequate hydration and protecting against external factors [ 153 , 154 , 156 ]. EFAs have therapeutic properties (e.g., anti-inflammatory and anti-allergic) and exert protective effects.…”
