Specifications of Corn Starch USP NF Grade:
DEFINITION
Corn Starch consists of the starch granules separated from the mature grain of corn [Zea mays L. (Fam. Gramineae)].
IDENTIFICATION
A.
Analysis: Examine under a microscope, using a mixture of glycerin and water (1:1) as a mounting agent.
Acceptance criteria: It appears either as angular polyhedral granules of irregular sizes with diameters ranging from 2–23 micro-m, or as rounded or spheroidal granules of irregular sizes with diameters ranging from 25–35 micro-m. The central hilum consists of a distinct cavity or two- to five-rayed cleft, and there are no concentric striations. Between orthogonally oriented polarizing plates or prisms, the starch granules show a distinct black cross intersecting at the hilum.
B.
Sample solution: 20 mg/mL in water
Analysis: Boil for 1 min, and cool.
Acceptance criteria: A thin, cloudy mucilage is formed.
C.
Sample solution: 1 mL of the mucilage obtained in Identification test B
Analysis: Add 0.05 mL of iodine and potassium iodide TS 2 to the Sample solution.
Acceptance criteria: An orange-red to dark blue color is produced, which disappears upon heating.
Residue on Ignition:
Sample: 1.0 g
Acceptance criteria: NMT 0.6%
Limit of Iron:
Acceptance criteria: --- corresponding to a limit of 10 ppm of iron.
Limit of Sulfur Dioxide: To pass the test.
Acceptance criteria: NMT 50 ppm
Limit of Oxidizing Substances:
Acceptance criteria: --- 20 ppm, calculated as H2O2.
Microbial Enumeration Tests and Tests for Specified Microorganisms: The total aerobic microbial count does not exceed 1000 cfu/g; the total combined molds and yeasts count does not exceed 100 cfu/g; and it meets the requirements of the test for the absence of Escherichia coli. Where it is intended for use in preparing Absorbable Dusting Powder, it also meets the requirements of the tests for absence of Staphylococcus aureus and Pseudomonas aeruginosa.
Loss on Drying:
Sample: 1 g
Analysis: Dry the Sample at 130C for 90 min.
Acceptance criteria: NMT 15.0%
pH:
Sample solution: Prepare a slurry by weighing 5.0 g of Corn Starch, transferring to a suitable nonmetallic container, and adding 25.0 mL of freshly boiled and cooled water.
Analysis: Agitate continuously at a moderate rate for 1 min. Stop the agitation and allow to stand for 15 min. Determine the pH to the nearest 0.1 unit.
Acceptance criteria: 4.0 to 7.0
Labeling: Where Corn Starch is intended for use in preparing Absorbable Dusting Powder, it is so labeled, and the label states that it must be subjected to further processing during the preparation of Absorbable Dusting Powder.
