Sec.  146.185  Pineapple juice.

    (a) Identity. (1) Pineapple juice is the juice, intended for direct 
consumption, obtained by mechanical process from the flesh or parts 
thereof, with or without core material, of sound, ripe pineapple (Ananas 
comosus L. Merrill). The juice may have been concentrated and later 
reconstituted with water suitable for the purpose of maintaining 
essential composition and quality factors of the juice. Pineapple juice 
may contain finely divided insoluble solids, but it does not contain 
pieces of shell, seeds, or other coarse or hard substances or excess 
pulp. It may be sweetened with any safe and suitable dry nutritive 
carbohydrate sweetener. However, if the pineapple juice is prepared from 
concentrate, such sweeteners, in liquid form, also may be used. It may 
contain added vitamin C in a quantity such that the total vitamin C in 
each 4 fluid ounces of the finished food amounts to not less than 30 
milligrams and not more than 60 milligrams. In the processing of 
pineapple juice, di methyl poly sil oxane complying with the 
requirements of Sec.  173.340 of this chapter may be employed as a 
defoaming agent in an amount not greater than 10 parts per million by 
weight of the finished food. Such food is prepared by heat 
sterilization, refrigeration, or freezing. When sealed in a container to 
be held at ambient temperatures, it is so processed by heat, before or 
after sealing, as to prevent spoilage.
    (2) The name of the food is ``Pineapple juice'' if the juice from 
which it is prepared has not been concentrated and/or diluted with 
water. The name of the food is ``Pineapple juice from concentrate'' if 
the finished juice has been made from pineapple juice concentrate as 
specified in paragraph (a) of this section. If a nutritive sweetener is 
added, the label shall bear the statement ``Sweetener added.'' If no 
sweetener is added, the word ``Unsweetened'' may immediately precede or 
follow the words ``Pineapple juice'' or ``Pineapple juice from 
concentrate.''
    (3) Label declaration. Each of the ingredients used in the food 
shall be declared on the label as required by the applicable sections of 
parts 101 and 130 of this chapter.
    (b) Quality. (1) The standard of quality for pineapple juice is as 
follows:
    (i) The soluble solids content of pineapple juice (exclusive of 
added sugars)

[[Page 449]]

without added water shall not be less than 10.5[deg] Brix as determined 
by refractometer at 20 [deg]C uncorrected for acidity and read as 
degrees Brix on International Sucrose Scales. Where the juice has been 
obtained using concentrated juice with addition of water, the soluble 
pineapple juice solids content (exclusive of added sugars) shall be not 
less than 12.8[deg] Brix, uncorrected for acidity and read as degrees 
Brix on the International Sucrose Scales.
    (ii) The acidity, as determined by the method prescribed in 
paragraph (b)(2)(ii) of this section, is not more than 1.35 grams of 
anhydrous citric acid per 100 milliliters of the juice.
    (iii) The ratio of the degrees Brix to total acidity, as determined 
by the method prescribed in paragraph (b)(2)(iii) of this section, is 
not less than 12.
    (iv) The quantity of finely divided ``insoluble solids'', as 
determined by the method prescribed in paragraph (b)(2)(iv) of this 
section, is not less than 5 percent nor more than 30 percent.
    (2) The methods referred to in paragraph (b)(1) of this section are 
as follows:
    (i) Determine the degrees Brix of the pineapple juice by the method 
prescribed in ``Official Methods of Analysis of the Association of 
Official Analytical Chemists,'' 13th Ed. (1980), section 31.009, 
``Solids by Means of Spindle--Official Final Action,'' which is 
incorporated by reference. Copies may be obtained from the AOAC 
INTERNATIONAL, 481 North Frederick Ave., suite 500, Gaithersburg, MD 
20877, or may be examined at the National Archives and Records 
Administration (NARA). For information on the availability of this 
material at NARA, call 202-741-6030, or go to: http://www.archives.gov/
federal--register/code--of--federal--regulations/ibr--locations.html.
    (ii) Determine the total acidity of the pineapple juice by titration 
by the method prescribed in Sec.  145.180(b)(2)(ix) of this chapter.
    (iii) Divide the degrees Brix determined as prescribed in paragraph 
(b)(2)(i) of this section by the grams of anhydrous citric acid per 100 
milliliters of juice, determined as prescribed in paragraph (b)(2)(ii) 
of this section, and report the results as ratio of degrees Brix to 
total acidity.
    (iv) Determine the quantity of ``insoluble solids'' in pineapple 
juice as follows: Measure 50 milliliters of thoroughly stirred pineapple 
juice into a cone-shaped graduated tube of the long-cone type, measuring 
approximately 4\3/16\ inches from tip to top calibration and having a 
capacity of 50 milliliters. Place the tube in a suitable centrifuge the 
approximate speed of which is related to diameter of swing in accordance 
with the table immediately below. The word ``diameter'' means the over-
all distance between the tips of opposing centrifuge tubes in operating 
position.

The milliliter reading at the top of the layer of ``insoluble solids,'' 
after centrifuging 3 minutes, is multiplied by two to obtain the 
percentage of ``insoluble solids.''
    (3) If the quality of pineapple juice falls below the standard 
prescribed in paragraph (b)(1) of this section, the label shall bear the 
general statement of substandard quality specified in Sec.  130.14 (a) 
of this chapter, in the manner and form therein specified.
    (c) Fill of container. (1) The standard of fill of container for 
pineapple juice, except when the food is frozen, is not less than 90 
percent of the total capacity of the container, as determined by the 
general method for fill of container prescribed in Sec.  130.12(b) of 
this chapter.
