Sodium Metabisulphite has reinforced the performance of a wide range of industrial-grade application through its extensive utility in food & beverages, water treatment, chemical & pharma, textile industry, pulp & paper etc. Sodium Metabisulphite has pandemic utility when used as industrial grade.
Due to changing lifestyles, major changes in food consumption patterns and eating habits are being noticed across the globe. There has been a significant rise in per capita consumption of packaged food and beverages, which is likely to have a major impact on the demand for sodium metabisulphite. Sodium Metabisulphite is used as a preservative in dried foods. Sodium Metabisulphite is also used as a softener in the dough for making bakery products. Sodium Metabisulphite is a subcategory of sulphur derivatives and is gaining popularity owing to the stringent regulations prohibiting the use of sulphur dioxide to reduce harmful emissions. Various grades, such as food-grade and industrial grade, of sodium metabisulphite, are being manufactured to be used across major end-use industries, such as paper and pulp, textile, water treatment and mining, amongst others.
Based on grade, the sodium metabisulphite market has been segmented into food grade, industrial/technical grade, and photo grade. Based on volume, the industrial-grade segment held the maximum share of over 90% last year due to their versatile usage in pulp & paper industry as an antichlor and for de-lignification purpose, in the textile industry as a bleaching agent for wool and jute, in the pharma industry for manufacturing of antioxidant drugs. Strong demand from Asian countries is subjected to the growing textile industry in their region which will propel the demand for fabrics like silk, viscose, hemp and other products. The product also has extended application in the mining industry as a floating agent and cyanide detoxification. It is also used as an oxygen scavenging agent in steam boilers & drilling water.
