Citric Acid (Lemon Salt) and Ascorbic Acid (Vitamin C) are two of the most widely used functional ingredients in the UK food industry. Although they are sometimes grouped together due to their antioxidant properties, they perform very different roles in food manufacturing. Choosing the right one — or the right combination — can significantly affect flavour, shelf life, colour stability, and regulatory compliance. This guide explains the key differences between citric acid

Dextrose Monohydrate, Sucrose, and Glucose Syrup are among the most commonly used carbohydrates in food manufacturing. While all provide sweetness and energy, they each bring unique functional properties, solubility characteristics, and processing benefits that make them suited to different applications. Understanding these differences is essential for manufacturers who want to optimise taste, texture, stability, and shelf life in their products. Table of Content Functional

Sodium Tripolyphosphate (STPP), also known as Pentasodium Triphosphate or E451(i) , is one of the most widely used phosphate additives in modern food processing. Valued for its water-binding capacity, emulsifying action, textural benefits, and mineral-chelation properties, STPP plays a key role in the quality, yield, and stability of processed foods. From seafood and meats to dairy and bakery products, STPP enhances texture, maintains moisture, stabilizes proteins, and impr

Dextrose Monohydrate —a crystallized form of D-glucose with one molecule of water—is one of the most widely used sweeteners and functional carbohydrates in the global food industry. Known for its mild sweetness, quick energy release, excellent solubility, and versatile functional properties, it is essential in bakery, confectionery, beverages, meat processing, and fermentation applications. Beyond sweetness, Dextrose Monohydrate serves as a fermentable sugar, a browning agent

Sodium Metabisulfite (SMBS) , known by the additive code E223, is a powerful and widely used preservative, antioxidant, and anti-browning agent essential for protecting the freshness, colour, safety, and stability of food products. Prized for its strong antimicrobial properties, it prevents microbial growth and enzymatic reactions that can degrade quality, making it indispensable in dried fruits, beverages, seafood, starch processing, fruit preparations, and dough conditionin
