The recommended drained weight values in Table I of this subpart are not incorporated in the grades of the finished product, since drained weight, as such, is not a factor of quality for the purpose of these grades. (b) Method for ascertaining drained weight. (1) The drained weight of canned spinach is determined when the product is at approximately room temperature (68° F.). The contents of the container is emptied upon a dry, previously weighed, U.S. Standard No. 8 circular sieve of proper diameter containing 8 meshes to the inch (0.0937 inch, ±3 percent, square openings). With the sieve flat on the tray, the container of spinach is placed open end down in the sieve in an upright position. The container is lifted off the spinach without spreading the spinach out on the sieve. The spinach is allowed to drain for exactly 2 minutes. The weight of the spinach and sieve minus the weight of the dry sieve is the drained weight of the spinach. The recommended fill of container is not incorporated in the grades of the TABLE I-RECOMMENDED MINIMUM DRAINED WEIGHTS FOR CANNED SPINACH (2) A sieve 8 inches in diameter is used for the equivalent of a No. 3 size can (404 x 700) and smaller and a sieve 12 inches in diameter is used for containers larger than the equivalent of a No. 3 size can. FACTORS OF QUALITY § 52.1907 Factors of quality. The grade of a lot of canned spinach is based on requirements for product characteristics with respect to the following quality factors: (a) Flavor and odor. (c) Character. (d) Stem material. (e) Damage. (f) Harmless extraneous material. § 52.1908 Sample unit size. (a) Compliance with the factors of flavor and odor, color, and character may be determined on: (1) The contents of an entire container, or (2) a representative subsample from containers yielding more than 10 ounces of drained weight. (b) Compliance with requirements for harmless extraneous material other than plant material is determined on the contents of an entire container. (c) Compliance with requirements for the factors of stem material, damage, and extraneous plant material shall be determined on subsamples as specified in Table II of this subpart. § 52.1909 Classification of defects. (a) General. Scoreable defects in the factors of color, character, extraneous plant material, other extraneous material, and damaged spinach are outlined in Tables III, IV, and V. (b) Extraneous plant material. Extraneous plant material includes root crowns, root stubs, and seed heads of the spinach plant and harmless grass and weeds of various kinds and texture. (c) Other extraneous material. Other harmless extraneous material includes grit, sand, silt, or other earthy material. (d) Damage. Damage includes discoloration or other similar injury on a leaf or stem or portion thereof which damage affects, materially affects, or seriously affects the appearance or eating quality of the portion of spinach and/or entire product. (e) Degrees of defect classes. Defects are classified as to minor, major, or severe. Each "X" mark in Tables III, IV, and V represents "one (1) defect". § 52.1911 Tolerances for color, character, damage, harmless extraneous material.

(a) Method for separation (1) Whole leaf; cut leaf styles. (1) Have available two dry, previously weighed U.S. Standard No. 8 circular sieves containing 8-meshes to the inch (0.0937, ±3 percent, square openings), not to exceed 8 inches in diameter. (ii) Place the sample unit of spinach in water in a deep grading tray. With gentle agitation, separate the leaves. Remove the individual leaves from the water and cut the attached stem off just below the last point of attachment of leaf material. (iii) Place the stem material on one sieve and the leaf material on another sieve. Remove all detached stems and pieces of stem and detached leaves and pieces of leaves from the water and place on their respective screen. (2) Chopped style. Place the sample unit, approximately one ounce at a time, in water in a deep grading tray. Remove the loose stem material and place on a dry sieve as mentioned under (a) (1) of this section. Pour the remaining leaf material on another sieve. Repeat until the stem material has been removed from the entire sample unit. (b) Drained weight of separated material. (1) Allow the leaf material and stem material to drain for 2 minutes from the time the separation has been completed. (2) Weigh separately: (1) The screen and leaf material, and (ii) the screen and stem material. The weight of the screen and leaf material minus the weight of the screen is the weight of the leaf material. The weight of the screen and stem material minus the weight of the screen is the weight of stem material. (c) Calculations. The percent of stem material is the weight of drained stem material divided by the sum of the weights of drained stem material and drained leaf material. Weight of stem material Weight of stem material + weight of leaf material § 52.1913 weights. = Percent of stem material.
