Content and bioaccessibility of bioactive compounds with potential benefits for macular health in tiger nut products

Tiger nut (Cyperus esculentus L.) oil: A review of bioactive compounds, extraction technologies, potential hazards and applications

“…Tiger nut is rich in antioxidant bioactive substances. The decomposition and release patterns of bioactive substances of four tiger nut products (flour, oil, milk with and without added sucrose) along gastrointestinal digestion were studied by Hernández-Olivas et al (2022) . They found that antioxidants such as phenolic compounds, vitamin E and carotenoids from tiger nut products, had good bioaccessibility, which suggested that tiger nut products can be used as functional foods to alleviate some diseases, such as, age-related macular degeneration.…”

Tiger nut/coconut dietary intervention as antidotal nutritional remediation strategy against neurobehavioural deficits following organophosphate-induced gut-brain axis dysregulation in mice

“…Tiger nut, (Cyperus esculentus) is a plant that grows naturally and is widely consumed in Spain, the Arabian Peninsula, East Africa, the tropical Mediterranean and many parts of West Africa. It is a tuberous plant highly valued for its numerous health benefits and nutritional benefits [51] . Black and brown-coloured species of tiger nut have been identified, both species have characteristic tastes and are popularly known as earthnut, yellow nut sedge, groundnut, rush nut and edible galingale [90] , [91] .…”

Functional and Antioxidative Characteristics of Soft Wheat and Tiger Nut (Cyperus esculentus) Flours Binary Blends

“…The cultivation of tiger nut aims at exploitation of its sweet, almond-flavored nuts, which are also a source of edible oil. Tiger nut flour is characterized by high nutritional and biological value as it contains: 28.36 ± 0.14 g/100 g lipids, 22.36 ± 0.13 g/100 g starch, 10.4 ± 0.4 g/100 g protein, 20.2 ± 0.2 g/100 g fibers, 15.8 ± 1.3 g glucose eq./100 g sugars [8], while the amino acid profile reveals valine having the highest concentration (67.59 µg/100 g), followed by leucine (3.019 µg/100 g), phenylalanine (1.767 µg/100 g), lysine (0.946 µg/100 g), histidine (1.048 µg/100 g) and tryptophan (0.055 µg/100 g), with other amino acids in smaller amounts [9]. The composition of pressed tiger nut oil contains saturated fatty acids such as palmitic (13.5%) and stearic acid (6.3%), and most common unsaturated fatty acid is oleic acid (67.4%) [10].…”
