The sample unit shall consist of 10 frozen fried fish portions taken at random from one or more packages as required. The portions are spread out on a flat pan or sheet and are examined according to Table 1. Deductions are not made for overall deviations in length or width up to inch. Uniformity is measured by the combined weight of the two heaviest portions divided by the combined weight of the two lightest portions. No deductions are made for weight ratios less than 1.20.
Distortion is measured as the greatest deviation from the long axis.
Breaks in the coating are objectionable bare spots through which the fish flesh is plainly visible. Lumps are objectionable outcroppings of breading on the portion surface. Ridges are projections of excess breading at the edges of the fish flesh. Depressions are objectionable visible voids or shallow areas which are lightly covered by breading. Blisters are measured by the swelling or exposed area in the coating resulting from the bursting or breaking of the coating.
