(b) Half sliced, half slices. "Half sliced" or "half slices" consist of semicircular halves of slices. A unit that is approximately one-half slice is considered to be a half slice.

(c) Broken sliced, broken slices. "Broken sliced" or "broken slices" consist of arc-shaped portions cut or broken from slices, which portions are not uniform in size or shape.

(d) Tidbits. "Tidbits" consist of sectors cut from slices. Tidbits are reasonably uniform in size and shape; they are predominantly from 16-inch to 1⁄2-inch thick; and, except for an occasional unit, each sector is not larger than one-sixth of the slice from which cut. Tidbits are considered "small tidbits" or "large tidbits" if they conform to the following approximate dimensions:

(1) Small tidbits.

(e) Chunks. "Chunks" consist of short, thick pieces cut from thick slices or from peeled, cored fruit. Chunks may or may not be symmetrical or uniform in shape and size. Predominantly, the units have a thickness greater than 1⁄2inch, a width greater than 16-inch, but a longest dimension (along any edge) not greater than 11⁄2 inches. Chunks which are symmetrical are considered "symmetrical chunks."

(f) Cubes, diced. "Cubes" or "diced" consist of cube-shaped pieces cut from slices or from peeled, cored fruit. Except for an occasional unit, the longest dimension (along any edge) of each unit is not greated than 16-inch.

(g) Spears, fingers. “Spears" or "fingers" consist of long, slender pieces cut parallel to the core axis from peeled, cored fruit cylinders. The units are not larger than one-sixth of the cylinder from which they are cut, and they are not less than 21⁄2 inches long.

(h) Crushed. "Crushed" consists of shredded or finely cut pieces of fruit flesh.

§ 52.1713 Grades of canned pineapple.

(a) "U.S. Grade A" or "U.S. Fancy" is the quality of sliced, tidbits, chunks, cubes, spears, or crushed canned pineapple that possesses a good color; that is practically uniform in size and shape for the applicable style; that is practically free from defects; that possesses a good character; that possesses a good flavor and odor; that is not excessively tart; and that for those factors which are scored in accordance with the scoring system outlined in this subpart the total score is not less than 90 points.

(b) "U. S. Grade B" or "U. S. Choice" is the quality of sliced, tidbits, chunks, cubes, spears, or crushed canned pineapple that possesses a reasonably good color; that is reasonably uniform in size and shape for the applicable style; that is reasonably free from defects; that possesses a reasonably good character; that possesses a fairly good flavor and odor; that is not excessively tart; and that for those factors which are scored in accordance with the scoring system outlined in this subpart the total score is not less than 80 points.

(c) "U. S. Grade C" or "U. S. Standard" is the quality of half sliced or broken sliced canned pineapple that possesses a good, reasonably good, or fairly good color; that, in the style of half slices, is practically uniform, reasonably uniform, or fairly uniform in size and shape; that, in the style of broken slices, is not uniform in size and shape; that is practically free, reasonably free, or fairly free from defects; that possesses a good, reasonably good, or fairly good character; that possesses a good or fairly good flavor and odor; that is not excessively tart; and that for those factors which are scored in accordance with the scoring system outlined in this subpart the total score is not less than 70 points.

(d) "Substandard" is the quality of canned pineapple that fails to meet the applicable requirements of U. S. Grade A or U. S. Fancy, U. S. Grade B or U. S.

Choice, or U. S. Grade C or U. S. Standard and is the quality of canned pineapple that may or may not meet the minimum standard of quality for canned pineapple issued pursuant to the Federal Food, Drug, and Cosmetic Act. Canned pineapple that is excessively tart is also "Below Standard in Quality-Good Food-Not High Grade" or "Below Standard in Quality-Excessively tart.” LIQUID MEDIA, FILL OF CONTAINER, AND DRAINED WEIGHTS

52.1714 Liquid media and Brix measurements for canned pineapple.

(a) "Cut-out" requirements for liquid media in canned pineapple are not incorporated in the grades of the finished product since sirup or any other liquid medium, as such, is not a factor of quality for the purposes of these grades. The "cut-out" Brix measurements, as applicable, for the respective designations are as follows:

(1) All styles other than crushed canned pineapple.

§ 52.1716 Recommended fill of container for other than canned crushed pineapple.

The recommended fill of container for canned pineapple is not incorporated in the grades of the finished product since fill of container, as such, is not a factor of quality for the purposes of these grades. It is recommended that each container of canned pineapple of all styles other than crushed style be as full of pineapple as practicable without impairment of quality and that the product and packing medium occupy not less than 90 percent of the volume of the container.

§ 52.1717

Drained weights for canned crushed pineapple.

(a) General. Minimum drained weights for canned crushed pineapple are not incorporated in the grades of the finished product since drained weight, as such, is not a factor of quality for the purposes of these grades; however, minimum drained weights for canned crushed pineapple other than "heavy pack" or "solid pack" are a standard of quality, and minimum drained weights for canned crushed "heavy pack" and "solidpack" pineapple are a standard of identity, under the Federal Food, Drug, and Cosmetic Act. Canned crushed pineapple other than "heavy pack" or "solid pack" which is less than 63 percent of the net weight of the contents of the container is:

Below Standard in Quality.
Good Food-Not High Grade.

(or)

Below Standard in Quality.
Contains excess liquid.

(b) Method for ascertaining the drained weight of canned crushed pineapple. Pour the contents of the can on a round sieve made with No. 8 wovenwire cloth complying with the specifications for such cloth in Table I of "Standard Specifications for Sieves," published March 1, 1940, in L. C. 584 of the United States Department of Commerce, National Bureau of Standards. Use a sieve 8 inches in diameter for containers of less than 3 pounds net contents and a sieve 12 inches in diameter for larger containers. Incline the sieve, without shifting the contents, to facilitate draining. Allow to drain for 2 minutes from the time the contents of the container are poured on

§ 52.1718 Recommended minimum drained weights for canned pineapple other than canned crushed pineapple.

(a) General. The minimum drained weight recommendations for the various styles of canned pineapple in Table II or Table III are not incorporated in the grades of the finished product since drained weight, as such, is not a factor of quality for the purposes of these grades.

(b) Method for ascertaining drained weight in canned pineapple other than canned crushed pineapple. The drained weight of canned pineapple other than canned crushed pineapple is determined by emptying the contents of the container upon a United States Standard No. 8 circular sieve of proper diameter containing 8 meshes to the inch (0.0937inch ±3 percent, square openings) so as to distribute the product evenly, inclining the sieve slightly to facilitate drain

age, and allowing to drain for two minutes. The drained weight is the weight of the sieve and pineapple less the weight of the dry sieve. A sieve 8 inches in diameter is used for the equivalent of No. 3 size cans (404 x 414) and smaller, and a sieve 12 inches in diameter is used for containers larger than the equivalent of the No. 3 size can.

(c) Compliance with recommended drained weights in canned pineapple other than canned crushed pineapple. Compliance with the recommended drained weights for canned pineapple other than canned crushed pineapple is determined by averaging the drained weights from all the containers which are representative of a specific lot and such lot is considered as meeting the recommendations if the following criteria are met:

(1) The average of the drained weights from all of the containers meets the recommended drained weight;

(2) One-half or more of the containers meet the recommended drained weight; and

(3) The drained weights from the containers which do not meet the recom

tainer sizes for these styles. Compliance with the recommended minimum slices in No. 10 cans only is ascertained by averaging the slices from all the containers which are representative of a specific lot and such lot is considered as meeting the recommendations: Provided, That in any single container the count of slices in "Small" slices, that average approximately 57 to 60 count, shall be not less than 54; in "Small" slices, that average approximately 64 count, shall be not less than 60; in "Medium" slices shall be not less than 48; and in "Large" slices shall be not less than 27.

apple that has been properly prepared and processed; and is free from objectionable flavors and objectionable odors of any kind.

(2) Fairly good flavor and odor. "Fairly good flavor and odor" means that the canned pineapple may be lacking in good flavor and odor but is free from objectionable flavors and objectionable odors of any kind.

(c) Definition of tartness; excessively tart. "Excessively tart" means that more than 1.35 grams of acid, calculated as anhydrous citric acid, is present in 100 milliliters of the pineapple liquid as defined and determined in accordance with paragraphs (d) and (e) of this section.

(d) Definition of acid. "Acid", in all styles of canned pineapple, means grams of acid, calculated as anhydrous citric acid, as contained in 100 milliliters of the liquid drained from the product 15 days or more after the pineapple is canned.

(a) Method for determination of acidity. Total acidity of the drained liquid is determined by the following method: (1) Measure with a pipette 10 milliliters of the unfiltered drained liquid into a 250-milliliter Erlenmeyer flask.

(a) (A) classification. Sliced, half sliced, broken sliced, tidbits, chunks, cubes, spears, or crushed canned pineapple that possesses a good color may be given a score of 27 to 30 points. Half sliced or broken sliced canned pineapple that scores 27 to 30 points shall not be graded above U.S. Grade C or U.S. Standard, regardless of the total score for the product (this is a partial limiting rule). "Good color" means that the color of the pineapple units or mass is bright and is characteristic of properly ripened and properly matured pineapple of similar varietal characteristics; and that there may be slight variations in shades of such characteristic color in the units, within each unit, or within the mass, and that white radiating streaks may be present: Provided, That such variations do not materially affect the appearance of the product.

(b) (B) classification. Sliced, half sliced, broken sliced, tidbits, chunks, cubes, spears, or crushed canned pineapple that possesses a reasonably good color may be given a score of 24 to 26 points. Half sliced or broken sliced canned pineapple that scores 24 to 26 points shall not be graded above U. S. Grade C or U. S. Standard, regardless of the total score for the product (this is a partial limiting rule); and other styles of canned pineapple that fall into this classification shall not be graded above U. S. Grade B or U. S. Choice, regardless of the total

score for the product (this is a limiting rule). "Reasonably good color" means that the color of the pineapple units or mass may be no more than slightly dull but is characteristic of properly matured pineapple of similar varietal characteristics; and that there may be marked variations in shades of such characteristic color in the units, within each unit, or within the 'nass, and that white radiating streaks may be present: Provided, That such variations do not seriously affect the appearance of the product.

(c) (C) classification. Half sliced or broken sliced canned pineapple that possesses a fairly good color may be given a score of 21 to 23 points. Half sliced or broken sliced canned pineapple that scores in this classification shall not be graded above U. S. Grade C or U. S. Standard, regardless of the total score for the product (this is a limiting rule). "Fairly good color" means that the color of the pineapple units may be dull but is characteristic of properly matured pineapple of similar varietal characteristics; and that there may be marked variations in shades of such characteristic color in the units or within each unit or white radiating streaks may be present which variations may seriously affect the appearance of the product.

(d) (SStd) classification. Canned pineapple that for any reason is off color or that fails to meet the applicable requirements of paragraph (b) or (c) of this section may be given a score of 0 to 20 points and shall not be graded above Substandard, regardless of the total score for the product (this is a limiting rule). § 52.1723 Uniformity of size and shape.

(a) General. The factor of uniformity of size and shape is not based on any detailed requirements and is not scored for the style of crushed pineapple; the other three factors (color, absence of defects, and character) are scored and the total is multiplied by 100 and divided by 80, dropping any fractions to determine the total score for canned crushed pineapple.

(b) Radial axis. "Radial axis" in the case of slices and half slices means the measurement along the radius from the inside arc to the outside arc.

(c) Length. In the case of tidbits and chunks, "length" means the measurement along the radius from the inside arc to the outside arc: and in the case
