Specifications of Maize Starch BP Ph Eur ( Corn Starch )
Action and use: Excipient.
When Starch is specified and the type is not indicated, Maize Starch, Potato Starch, Rice Starch, Wheat Starch or, in tropical countries where these are not available, Tapioca Starch may be supplied or used.
DEFINITION
Maize starch ( Corn Starch ) is obtained from the
caryopsis of Zea mays L.
CHARACTERS
Appearance: Matt, white to slightly yellowish, very fine powder
which creaks when pressed between the fingers.
Solubility: Practically insoluble in cold water and in ethanol (96
per cent). The presence of granules with cracks or irregularities on the
edge is exceptional.
IDENTIFICATION
A. Examined under a microscope, using not less than 20
× magnification and using equal volumes of glycerol and water, it appears as either angular polyhedral granules of irregular sizes with
diameters ranging from about 2 μm to about 23 μm or as rounded or
spherical
granules of irregular sizes with diameters ranging from about 25 μm to about
35 μm. The central hilum consists of a distinct cavity or two-to five-rayed
cleft and there are no concentric striations. Between crossed nicol prisms,
the starch granules show a distinct black cross intersecting at the hilum.
B. Suspend 1 g in 50 ml of water,
boil for 1 min
and cool. A thin, cloudy mucilage is formed.
C. To 1 ml of the mucilage obtained in identification
test B add 0.05 ml of iodine solution. An orange-red to dark blue
colour is produced which disappears on heating.
TESTS
pH: 4.0 to 7.0.
Shake 5.0 g with 25.0 ml of carbon dioxide-free
water for 60 s. Allow to stand for 15 min.
Foreign matter: Examined under a microscope using a mixture of equal
volumes of glycerol and water, not more than traces of matter
other than starch granules are present. No starch grains of any other origin
are present.
Oxidizing substances: Maximum 20 ppm, calculated as H2O2.
Sulphur dioxide: Maximum 50 ppm.
Iron: Maximum 10 ppm.
Loss on drying: Maximum 15.0 per cent, determined on 1.000 g by drying
in an oven at 130C for 90 min.
Sulphated ash: Maximum 0.6 per cent, determined on 1.0 g.
Microbial contamination: Total viable aerobic count not more than 103 bacteria and 102 fungi per
gram, determined by plate count. It complies with the test for Escherichia
coli.
Corn Starch USP NF ( Maize Starch )
Corn Starch ( Maize Starch ) consists of the starch granules separated from the mature grain of corn
Identification:
A: Under a microscope, using not less than 20×
magnification and using a mixture of glycerin and water (1:1) as a mounting
agent, it appears either as angular polyhedral granules of irregular sizes
with diameters ranging from about 2 µm to about 23 µm, or as rounded or
spherical granules of irregular sizes with diameters ranging from about 25
µm to about 35 µm. The central hilum consists of a distinct cavity or two-
to five-rayed cleft, and there are no concentric striations. Between crossed
nicol prisms, the starch granules show a distinct black cross intersecting
at the hilum.
B: Suspend 1 g of it in 50 mL of water, boil for
1 minute, and cool: a thin, cloudy mucilage is formed.
C: To 1 mL of the mucilage obtained in Identification test B, add 0.05 mL of iodine and potassium iodide
TS 2: an orange-red to dark blue color is produced, which disappears on
heating.
Microbial limits: The total aerobic microbial
count does not exceed 1000 cfu per g, the total combined molds and yeasts
count does not exceed 100 cfu per 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.
pH— 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. Agitate continuously at a moderate rate
for 1 minute. Stop the agitation, and allow to stand for 15 minutes.
Determine the pH to the nearest 0.1 unit: the pH, determined
potentiometrically, is between 4.0 and 7.0.
Loss on drying: Dry about 1 g, accurately
weighed, at 130 for 90 minutes: it loses not more than 15.0% of its weight.
Residue on ignition: not more than 0.6%,
determined on a 1.0-g test specimen.
Limit of iron—a limit of 10 µg of iron per g.
Limit of oxidizing substances—20 µg per g,
calculated as H2O2.
Limit of sulfur dioxide: not more than 50 µg per
g.
