Most of the people toss away fish heads for many reasons. Some people say that fish heads are inedible or not safe to eat. Others say that they almost choke and they couldn’t breathe due to the obstruction of their esophagus because of the disgusting taste of the fish heads. Some people have no idea about the contents of the fish heads that they insist are for garbage cans.
Bioactive peptides identified in range of foods, which includes fish especially, in the contents of a silver-banded whiting fish or Asuhos. Bioactive peptides like Hyaluronic Acid from food proteins offer major potential in nutraceutical or derived from the words “nutrition” and “pharmaceutical”.
Asuhos contains Hyaluronic acid which can be applied externally to improve or enhance the pleasing features of skin, hair, lips and eyes. Also it can be used to lessen or even prevent the oxidation of other chemicals in human body.
Dr. Bernadeth Ticar, Western Visayas College of Science and Technology’s (now ISAT U) pride, entitled her ongoing research (June2015-May 2016): Bioactive Hyaluronic Acid from heads of Silver-Banded Whiting for Nutraceutical Use. The chemicals found on the heads of silver-banded whiting fish can be used in cosmetics as anti-aging and anti-oxidant.
With a scientific name of Sillago Argentifasciata, silver-banded whiting fish, one of the 29 species of genus Sillago and one of the three genera in smelt-whiting family Sillaginidae, inhabits the coastline of the Philippines, especially in Palawan.
Its name was taken from the brilliant silvery strip across its elongated and slightly compressed body with two apparent dorsal fins by Martin and Montalban in 1935 from a single physical sample of an organism collected in the waters of Western Central Pacific; Lumbucan Island, Palawan Philippines. The specie’s head contains Hyaluronic acid which can be mixed in cosmetics.
Hyaluronic Acid, also known as Hyaluronan or Hyaluronate (HA) is a carbohydrate, specifically, a mucopolysaccharide occurring naturally throughout the human body. It can be several thousands of sugars. When not bound to other molecules, it binds to water and gives off a stiff viscous or a gel-like water holding molecule that is the space filler and cushioning agent in all mammals. HA cushions joints, nerves, hydrates skin and hair, and fills the eye. Although originally discovered in 1934 by Karl Meyer, HA gained momentum only after a visit by a reporter to a Japanese village of Yuzuri Hara to find out why both men and women in their 80’s and 90’s had smooth wrinkle free skin, flexible joints, full heads of hair and activity levels that defied their age.
Another research discussed when was HA discovered. It was when first commercially used in 1942 when Endre Balazs applied for a patent to use it as a substitute for egg white in bakery products. No other molecule had ever been discovered that has such unique properties to human body.
Scientific studies have shown that HA improves skin hydration, stimulates production of collagen in skin, works as an antioxidant and free radical scavenger, maintains skin’s elasticity, cushions joints and nerve tissues, and protect against numerous possible eye concerns.
Because Ha is one of the most hydrophilic (water-loving) molecules in nature with numerous benefits for the human body, today it can be described as “nature’s moisturizer”.
