Refiners' Sirup Grades & Standards

Refiners' sirup means a liquid product obtained from the refining of cane or beet sugar. The total soluble nonsugar solids content of refiners' sirup exceeds 6 percent of the total soluble solids. All of the sirup constituents have been subjected to the processes of clarification and decolorization, or equivalent purification, and it may be partially or wholly inverted.

Grades of Refiners' Sirup

  1. U.S. Fancy or U.S. Grade A Refiners' Sirup consists of refiners' sirup which possesses a flavor characteristic of refiners' sirup of fancy quality; which contains no sediment; which is free of foreign matter; which has a Brix solids content of not less than 72 percent when corrected to 20E C. (68E F.); which has a ratio of total sugars (sucrose plus reducing sugars) to Brix solids of not less than 92 percent; which has a ratio of sulfated ash to Brix solids of not more than 3.0 percent; an which possesses a color no darker that RS Color Standard No. 1.
  2. U.S. Choice or U.S. Grade B Refiners' Sirup consists of refiners' sirup which possesses a flavor characteristic of refiners' sirup of choice quality; which contains no sediment; which is free of foreign matter; which has a Brix solids content of not less than 72 percent when corrected to 20E C. (68E F.); which has a ratio of total sugars (sucrose plus reducing sugars) to Brix solids of not less than 86 percent; which has a ration of sulfated ash to Brix solids of not more than 6 percent; and which possesses a color no darker than RS Color Standard No. 2.. 
  3. U.S. Extra Standard or U.S. Grade C Refiners' Sirup consists of refiners' sirup which possesses a flavor characteristic of refiners' sirup of standard quality; which contains no excess of sediment; which is practically free of foreign matter; which has a Brix solids content of not less than 76 percent when corrected to 20E C. (68E F.); which has a ratio of total sugars (sucrose plus reducing sugars) to Brix solids of not less than 78 percent; which has a ratio of sulfated ash to Brix solids of not more than 10 percent; and which possesses a color no darker than RS Color Standard No. 3.
  4. U.S. Standard or U.S. Grade D Refiners' Sirup consists of refiners' sirup which possesses a flavor characteristic of refiners' sirup of standard quality; which contains no excess of sediment; which is practically free of foreign matter; which has a Brix solids content of not less than 76 percent when corrected to 20E C. (68E F.); which has a ration of total sugars (sucrose plus reducing sugars) to Brix solids of not less than 70 percent; and which has a ratio of sulfated ash to Brix solids of not more than 14 percent.
  5. U.S. Substandard or U.S. Grade E Refiners' Sirup consists of refiners' sirup that fails to meet the specifications for U.S. Standard Refiners' Sirup.
