Psylliium Seed Husk

Psyllium is a soluble fibre derived from the seeds of Plantago ovata. The seed consists of 65% insoluble and 35% soluble polysaccharides (cellulose, hemicellulose and lignin). Psyllium seed husk is classified as mucilaginous fibre due to its powerful ability to form a gel in water. This ability is mainly due to its role to retain water in order to prevent the seed from drying out (Kumar et al., 2015).

Technical Properties of Psyllium Seed Husk

The remarkable property of Psyllium seed husk mucilage makes it suitable to be used as a thickening agent in food and beverage industry. It can be applied as a basic stabiliser in ice-creams and as an ingredient in chocolates. On top of that, Psyllium can be used as a substitute, thickener and binder in health drinks, beverages, ice cream, bakery products, rice, jams, instant noodles and breakfast cereals as it helps to improve the fibre content that brings various health benefits. Psyllium Husk can be added into fresh fruit drinks or flavoured drinks to enhance their mouthfeel. It also helps to improve the softness and texture of the drinks.

Health Benefits of Psyllium Husk

  • Lowering of Blood Cholesterol

The soluble fibre of Psyllium binds to the bile acids to form a complex which inhibits the re-absorption in small intestine. This promotes the synthesis of new bile acids by cholesterol metabolism, hence lowering the blood cholesterol level. Psyllium husk also influences the absorption of cholesterol and fat which contributes to the cholesterol-lowering effect (Li et al., 2017).

  • Digestive Function

Psyllium polysaccharides are hydrophilic molecules with the ability to absorb and hold water. This makes psyllium an effective agent for stool-bulking, thus helps in relieving diarrhea and constipation as the water-soluble fibres bind the water by gelation to entrap its molecules like a sponge. The increase of water content in stool when consuming Psyllium fibres helps soften the stool and relieve constipation (Li et al., 2017). Besides, Psyllium is a useful supplement for weight control where it helps to control bowel function, thus reducing the feeling of fullness (Khalid et al., 2015). 

  • Hemorrhoids

Hemorrhoids are abnormally enlarged vein mainly due to persistent increase in venous pressure, occurring inside the anal sphincter of the rectum and beneath the mucous membrane or outside the anal sphincter and beneath the surface of the anal skin (Kumar et al., 2015). Addition of the dietary fibre in the way of bulk-forming agent Psyllium in the diets of patients with bleeding internal hemorrhoids is found to have a significant effect in the reduction of congested hemorrhoid cushions and could improve internal bleeding hemorrhoids (Li et al., 2017).
