Haw. Code R. § 4-44-2 - Standard requirements and procedures
(a) Compliance with
the requirements of these standards shall not excuse failure to comply with the
provisions of the Federal Food, Drug and Cosmetic Act, or with applicable State
laws and regulations.
(b) The grade
of a lot of a processed product covered by this chapter is determined by the
procedures set forth in the United States Department of Agriculture Regulations
Governing Inspection and Certification of Processed Fruits and Vegetables and
Related Products, May 1983, which is made a part of this chapter.
(c) Methods of analysis to ascertain the
requirements of this chapter shall be as provided in subsections (d) through
(g).
(d) The viscosity reading in
seconds shall be determined by using a viscometer similar to that shown in
"Figure 1, Capillary CPC Viscometer, 8/24/68" which is located at the end of
this chapter and made a part of this chapter, which has been calibrated to give
a flow time of thirteen seconds at twenty-five degrees celsius with distilled
water. Corrections can be made for other temperatures by using the formula Y
equals 19.12 minus 0.32T plus 0.003T2, where T is
temperature in degrees celsius and Y is time of flow in seconds. Procedure for
measurement of viscosity shall be as follows:
(1) Clamp viscometer in a vertical
position;
(2) Close tip of
capillary tube with a finger;
(3)
Fill reservoir well above the gauge line with well-mixed sample;
(4) Obtain temperature reading in
celsius;
(5) Allow a small amount
of sample to flow to fill the capillary tube;
(6) Reclose tip and refill the reservoir to
near overflowing and level off with a straight-edged spatula; and
(7) Release finger from tip and
simultaneously with a stop watch, time the free flow of the sample until the
upper edge of the liquid meniscus reaches the gauge line of the reservoir. The
flow time, expressed in seconds with temperature correction applied, is the
viscosity reading of the sample.
(e) The percentage of centrifuged solids
shall be determined as follows:
(1) Measure
at about twenty-five degrees celsius, fifty ml of thoroughly stirred prepared
sample into a cone shaped graduated fifty ml centrifuge tube which measures
approximately four and three-fourths inches from the tip to the top calibration
and has a capacity of fifty ml, or any centrifuge tube that will give
equivalent results;
(2) Place the
tube in a suitable centrifuge, the approximate speed of which is related to the
diameter of swing in accordance with "Table I, Approximate Revolution Of
Centrifuge Machine, 8/24/68", which is located at the end of this chapter and
made a part of this chapter;
(3)
Centrifuge at the indicated speed for ten minutes and allow the centrifuge to
coast to a stop; and
(4)
Immediately after the centrifuge stops, take the ml reading at the top of the
layer of solid material in the bottom of the tube and multiply by two to obtain
the percentage of centrifuged solids.
(f) The general procedure for mold count,
using standard equipment and standard measurements, described in the Official
Methods of Analysis of the Association of Official Analytical Chemist 1984
shall be employed in determining stone cell count. Procedure for stone cell
count shall be as follows:
(1) Use a
well-mixed sample;
(2) The
microscope used should have an eyepiece micrometer ruled into squares, each of
which is equal to one-sixth of the diameter of the eyepiece diaphragm
opening;
(3) Estimate the area
covered by the stone cells on the basis of what part or how many squares on the
eyepiece are covered by stone cells and total the results to arrive at the
stone cell count (e.g., if the areas covered in four fields are one-fourth
square, one-half square, two and three-fourths squares, and one and one-half
squares, respectively, the stone cell count would total five for these four
fields); and
(4) For the final
count examine one hundred fields, with the count being the number of squares in
the one hundred fields that are covered.
(g) The mold count shall be determined by the
Howard method as described in the 1984 edition of the Official Methods of
Analysis of the Association of Official Analytical Chemists.
