Coated Salt Supplement to Boost Fish Health and Biomass, Finds Research


A team of researchers in Brazil explored the use of Na-butyrate or additive coated with buffer or palm oil in the diet of Nile tilapia and studied the influence of feed additive on growth, sexual reversion, and health of fish. The study published in Aquaculture journal found that adding Na-butyrate does not alter the process of sexual reversal. However, receiving a large amount of coated supplement resulted in the rise in fish yield and biomass in fish.

Studies in past have shown that organic acids such as glutamic, quinic, tartaric, shikimic, citric, fumaric, and others influence the nutritional state of the food and improves quality. Moreover, the team of researchers from Brazil also found that salts from organic acids can be used in feed additive to support the health of the farm raised fish. The additives have also been linked to reducing the growth of bad bacteria and improving digestion, nutrition absorption and performance in the fish.

According to the researchers, work and studies exploring the use of salts or organic acids have been started in recent years. Majority of the work and studies have examined the use of formic acid or citric acid and other organic acids. Researchers also stated that organic acids within animals act in different ways, including diffusion through the bacterial cell wall, reducing internal pH, or limit enzymatic reactions that may promote bacterial death.

The feeding trial using organic acid with Nile tilapia saw growth and improvement in disease resistance. Moreover, among the organic salts that are used in animal production, butyrate has gained traction owing to its positive effect on animals’ gastrointestinal tract.

The researchers also pointed out that there is a need for adaptations for using organic acids and salts in fish diets. Because there is an essential physiological and anatomical difference in the digestive system of aquatic animals as compared to the terrestrial animals.

The results of the study also showed that using coated forms of Na-butyrate with a concentration of 0.5% oil or buffer resulted in the rise in zootechnical parameters of animals, while not influencing sexual reversion. Thus, emerging as the viable alternative that can be applied commercially.

Over the recent past, there has been a significant rise in the use of synthetic tartaric acid in drug formulations as an excipient to prepare tablets, granulates, and powder. Moreover, governments and regulatory bodies in developed countries are taking steps to streamline the approval process of excipients in the drug development process. Hence, tartaric acid including synthetic tartaric acid is likely to witness growing demand in pharmaceuticals, and food and beverages, owing to numerous benefits. The synthetic tartaric acid market is expected to reach US$ 804.7 million by 2027 end.

The food and beverage industry has also witnessed the increasing use of synthetic tartaric acid in the last couple of years. Moreover, with the rise in consumption of wine globally owing to the changing lifestyle and increasing population, the demand for synthetic tartaric acid has also increased in the wine production as the acidity regulator and manage pH level of wine.
