"Acid" means grams of acid, calculated as anhydrous citric acid, per one hundred ml of canned guava nectar determined by titration with sodium hydroxide solution using phenolphthalein and methylene blue as indicators.
"Canned guava nectar" means the diluted, unfermented juice and pulp obtained from the sound, mature, fresh fruit of the Psidium guajava or Psidium cattleianum guava plant, which fruit has been properly washed and properly comminuted; is packed with the addition of potable water, with or without the addition of nutritive sweetening ingredients or other suitable sweeteners for dietetic packs, fruit acids, ascorbic acid, stabilizers, certified food colors, or preservatives, provided that at least one-fourth, by weight, of the nectar consists of guava juice and pulp in natural proportions; and is sufficiently processed by heat to assure preservation of the product in hermetically sealed containers.
"Dietetic product" means canned guava nectar that is packed to meet the requirements of a special diet.
"Fairly free from defects" means practically no seeds or portions of seeds are present; the drinking quality and appearance of the nectar are not seriously affected by the presence of grittiness, objectionable material, any other defect not specifically mentioned, or any combination of these defects; the stone cell count does not exceed seventy when centrifuged solids do not exceed thirty-five per cent and does not exceed seventy by more than two per cent for each one per cent that the centrifuged solids exceed thirty-five per cent; the mold count does not exceed fifteen per cent; and the aggregate area of any black or brown deposit at the bottom of the centrifuge tube after centrifuging does not exceed the area of a circle three-sixteenths inch in diameter.
"Fairly good consistency" means the nectar flows readily; is not excessively thick; shows no more than slight coagulation; has a viscometer reading of not less than eighteen seconds at twenty-five degrees celsius; and contains not less than twenty-five per cent centrifuged solids.
"Good color" means the color of the canned guava nectar is typical of nectar prepared from freshly extracted guava juice and pulp, or typical of artificially colored guava nectar, and is free from browning or other abnormal color by any cause.
"Good consistency" means the nectar flows readily; shows very little or no tendency to separate; shows no coagulation; has a viscometer reading of not less than twenty-three seconds at twenty-five degrees celsius; and contains not less than thirty per cent centrifuged solids.
"Good flavor" means the product has a fine, distinct canned guava nectar flavor which is free from fermented, immature, or other off-flavor of any kind and the brix reading is not less than ten and one-half degrees nor more than fourteen degrees; the acid reading is not less than three-tenths gram nor more than one-half gram per one hundred ml of nectar; and the brix to acid ratio is not less than twenty-eight to one nor more than forty to one. There shall be no brix and no brix to acid ratio requirements for dietetic products.
"Practically free from defects" means the nectar contains no seeds or portions of seeds; the drinking quality and appearance of the nectar is not more than slightly affected by the presence of grittiness, harmless extraneous material, objectionable material, any other defect not specifically mentioned, or any combination of these defects; the stone cell count does not exceed forty when centrifuged solids do not exceed thirty-five per cent and does not exceed forty by more than one per cent for each one per cent that the centrifuged solids exceed thirty-five per cent; the mold count does not exceed fifteen per cent; and the aggregate area of any black or brown deposit at the bottom of the centrifuge tube after centrifuging does not exceed the area of a circle two-sixteenths inch in diameter.
"Reasonably good color" means the color of the canned guava nectar is fairly typical of nectar prepared from freshly extracted guava juice and pulp, or fairly typical of artificially colored guava nectar, and is not excessively dull or brown colored or seriously off-colored from any cause.
"Reasonably good flavor" means the product has a fairly typical canned guava nectar flavor which is practically free from fermented, immature, or other off-flavor of any kind and the brix reading is not less than ten degrees nor more than fifteen and one-half degrees; the acid reading is not less than one-fourth gram nor more than six-tenths gram per one hundred ml of nectar; and the brix to acid ratio is not less than twenty to one nor more than fifty-five to one. There shall be no brix and no brix to acid ratio requirements for dietetic products.
Example: Hawaii Fancy, Dietetic Product or Hawaii Grade C, Dietetic Product.
