Modified Carbohydrates (Starches)

  • Propoxylated carbohydrates, or starches, are used in a variety of applications in the construction, paint, food and pharmaceutical industries. Common modified starches used today include corn, wheat, potato, rice and tapioca. Guar and guar gum are also used in some industrial applications.

  • Hydroxypropyl starches are made by the etherification of some of the hydroxyl groups on the starch molecule. Due to their enhanced freeze/thaw stability, modified food starches also help frozen food products maintain their integrity between refrigeration, freezing and re-heating. Food starches modified with propylene oxide are used as thickening agents or stabilizers in the manufacture of foodstuffs such as canned soups, desserts, microwavable dinners and puddings.

  • Industrial starches, commonly modified with either ethylene oxide, propylene oxide or quaternary amines, have a wide range of physical properties. Physical properties of the starches such as viscosity, lubricity, and freeze/thaw stability can be tailored to meet the specific requirements of the intended application. Modified industrial starches are used in several applications such as oil field drilling chemicals, paints, adhesives and construction industry applications.

  • METHOCEL* cellulose ethers are water-soluble methylcellulose and hydroxypropyl methylcellulose polymers that bind, retain water, thicken, form films, lubricate, and much more. They add physical properties and performance to products, including building materials, food, personal care products and pharmaceuticals.
