Sodium Citrate
Sodium Citrate is the sodium salt of citric acid, available as a white, crystalline powder or granules. It functions primarily as a buffering agent, acidity regulator, and sequestrant in food, pharmaceutical, and industrial applications. It helps maintain pH stability, enhances flavor, and prevents metal ion-induced spoilage. The 25kg packaging is typical for bulk industrial or food processing use.

Beta Carotene
Beta Carotene is a concentrated formulation of beta carotene, a naturally occurring red-orange pigment found in plants and fruits. It is a precursor to vitamin A and a potent antioxidant that helps protect cells from oxidative damage. This product, typically suspended in an oil base or suitable carrier, is widely used as a natural colorant, nutritional supplement, and cosmetic ingredient. Beta Carotene 30% SUN offers enhanced stability under sunlight exposure, making it ideal for food, feed, and cosmetic applications where light stability is critical.
Blueberry Toppings
Blueberry Toppings are sweet, fruit-based condiment preparations made primarily from blueberries, sugar, and thickening agents. They are characterized by a vibrant blue-purple color, fruity aroma, and a sweet-tart flavor profile. Typically semi-viscous with chunks or pureed pieces of blueberry, these toppings are used as finishing ingredients in desserts, breakfast foods, and beverages. Blueberry toppings may be prepared as preserves, syrups, or glazes and often contain natural flavors and preservatives to enhance shelf life and sensory appeal.
Calcium Lactate Pentahydrate
Calcium Lactate Pentahydrate is a white, crystalline, odorless powder that is the calcium salt of lactic acid with five molecules of water of crystallization. It is moderately soluble in water and has a slightly alkaline pH in solution. Widely used as a calcium supplement in the pharmaceutical and food industries, it is known for its good bioavailability and safety profile. Calcium Lactate Pentahydrate is utilized to prevent and treat calcium deficiencies and plays a role in bone health, muscle function, and enzyme activity. It also finds applications as a food additive and firming agent.
Calcium Sulphate
Calcium Sulphate is an inorganic compound composed of calcium, sulfur, and oxygen, commonly found in two forms: dihydrate (gypsum, CaSO4·2H2O) and anhydrous (CaSO4). It appears as a white or off-white crystalline powder or granules with low solubility in water. Calcium Sulphate is widely used in construction, agriculture, pharmaceuticals, food industry, and various industrial applications. It acts as a filler, hardening agent, and drying agent due to its physical and chemical properties. The dihydrate form (gypsum) is notable for use in plaster and cement, while the anhydrous form is often used as a drying agent and in refractory materials.
Ferrous Gluconate
Ferrous Gluconate is an iron salt of gluconic acid, appearing as a pale greenish-blue or green crystalline powder or granules. It is widely used as a nutritional iron supplement and food additive due to its good bioavailability and relatively low toxicity compared to other iron salts. Ferrous Gluconate is water-soluble, providing a stable source of ferrous iron (Fe²⁺) that is easily absorbed in the gastrointestinal tract. This compound is commonly employed in pharmaceuticals, food fortification, and medical formulations to treat or prevent iron deficiency anemia. It is also used as a reducing agent and color stabilizer in various industrial applications.
Iodised Salt
Iodised Salt is table salt (sodium chloride) fortified with a small, controlled amount of iodine, typically in the form of potassium iodate or potassium iodide. It appears as fine white crystalline granules, odorless, and with a characteristic salty taste. The addition of iodine helps prevent iodine deficiency disorders (IDD) such as goiter, mental impairment, and developmental abnormalities. Iodised Salt is widely used in households, food processing, and animal nutrition to ensure adequate dietary iodine intake.
Magnesium Sulphate (Epsom Salt)
Magnesium Sulphate Epsom Salt, commonly known as Epsom Salt, is an inorganic salt composed of magnesium, sulfur, and oxygen with the formula MgSO₄. It typically appears as colorless or white crystalline granules and is highly soluble in water. In its heptahydrate form (MgSO₄·7H₂O), it is widely used in agriculture, pharmaceuticals, food, and industrial applications. Epsom Salt is valued for its muscle relaxant, laxative, and magnesium supplementation properties, as well as for its role in improving soil fertility and plant growth.
Potassium Lactate
Potassium Lactate is the potassium salt of lactic acid, typically available as a clear, colorless to pale yellow liquid or solid powder. It functions primarily as a food additive, humectant, and preservative with antimicrobial properties. Widely used in the food industry, it also finds applications in pharmaceuticals, cosmetics, and industrial processes. Potassium Lactate helps improve moisture retention, extend shelf life, and enhance safety by inhibiting microbial growth.
