Abstract
Abstract The present invention is directed to a fish improvement composition, in its relatively dry form and in its form as a solution, which includes a phosphate mixture component containing a multi-compound phosphate mixture with a specified P 2 O 5 content range, a preservative component selected from potassium sorbate, sorbic acid and mixtures thereof, and an acid component capable of adjusting the pH of a product containing the composition and a suitable liquid vehicle into the range of from about 5.4 to 6.7.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
188 words
A fish treatment composition which comprises: (a) a phosphate mixture containing at least two of the following groups: (i) up to about 95% of sodium pyrophosphate (-diphosphate), potassium pyrophosphate (-diphosphate), or a mixture thereof; (ii) from about 14% to about 90% of sodium tripolyphosphate, potassium tripolyphosphate, or a mixture thereof; (iii) from about 5% to about 50% of sodium hexametaphosphate, potassium hexametaphosphate or a mixture thereof, wherein said percentages are by weight based on the weight of the phosphate mixture, and said phosphate mixture has a statistical average content by weight of P 2 O 5 of about 47% to about 68%; and (b) a preservative consisting of potassium sorbate, sorbic acid or a mixture thereof, in an amount by weight of about 0.1 to about 0.2 parts per part of said phosphate mixture; and, (c) a sufficient amount of an acid component selected from the group consisting of one or more of malic, tartaric, and gluconic acids or the edible salts thereof, such that when said composition is present in a suitable liquid vehicle, a pH in the range of about 5.4 to about 6.7 is attained.
Claim 2
Dependent Claim
188 words
A fish treatment composition which comprises: (a) a phosphate mixture containing at least two of the following groups: (i) up to about 95% of sodium pyrophosphate (-diphosphate), potassium pyrophosphate (-diphosphate), or a mixture thereof; (ii) from about 14% to about 90% of sodium tripolyphosphate, potassium tripolyphosphate, or a mixture thereof; (iii) from about 5% to about 50% of sodium hexametaphosphate, potassium hexametaphosphate or a mixture thereof, wherein said percentages are by weight based on the weight of the phosphate mixture, and said phosphate mixture has a statistical average content by weight of P 2 O 5 of about 47% to about 68%; and (b) a preservative consisting of potassium sorbate, sorbic acid or a mixture thereof, in an amount by weight of about 0.1 to about 0.2 parts per part of said phosphate mixture; and, (c) a sufficient amount of an acid component selected from the group consisting of one or more of malic, tartaric, and gluconic acids or the edible salts thereof, such that when said composition is present in a suitable liquid vehicle, a pH in the range of about 5.4 to about 6.7 is attained.
