Haw. Code R. § 4-44-4
"Absence of defects" means the degree of freedom from seeds or portions of seeds, harmless extraneous material, grittiness caused by stone cells, objectionable material, and other defects not specifically mentioned that affect the appearance or drinking quality of the product.
"Acid" means grams of acid, calculated as anhydrous citric acid, per one hundred ml of nectar determined by titration with sodium hydroxide solution using phenolphthalein and methylene blue as indicators.
"Common guava nectar base" means nectar base made from the fruit of the Psidium guajava tree, or from a mixture of fruits from the Psidium guajava and Psidium cattleianum plants of which mixture not less than seventy-five per cent shall be the fruit from the Psidium guajava plant.
"Consistency" means the viscosity, the tendency of insoluble solids to separate, and the percentage of centrifuged solids of the guava nectar prepared from the frozen guava nectar base.
"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, dark specks, harmless extraneous 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; has a viscometer reading of not less than sixteen seconds at twenty-five degrees celsius; and contains not less than eighteen per cent centrifuged solids.
"Frozen guava nectar base" means the undiluted, unconcentrated, unfermented juice and pulp obtained from sound, mature, fresh, and properly washed fruit of the Psidium guajava or Psidium cattleianum guava plant, packed with the addition of non-liquid sweetening ingredients and with or without the addition of a certified food coloring, fruit acids, or ascorbic acid; processed in accordance with good commercial practice; and frozen and maintained at temperatures sufficient for the preservation of the product.
"Good color" means the color is typical of nectar prepared from freshly extracted guava puree, or typical of artificially colored guava nectar, and is free from browning or other abnormal color by any cause.
"Good consistency" means the prepared nectar flows readily; shows very little or no tendency to separate; has a viscometer reading of not less than twenty seconds at twenty-five degrees celsius; and contains not less than twenty-two per cent centrifuged solids.
"Good flavor" means the product has a fine, distinct, and substantially typical flavor of guava nectar prepared from freshly expressed guava puree and the flavor is free from bitter, oxidized, immature fruit, or other off-flavors; 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.
"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 dark specks, objectionable material, grittiness, harmless extraneous 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.
"Prepared guava nectar" means the nectar prepared by diluting the guava nectar base with water based on the manufacturer's directions or label specifications, or by the addition of two and one-half volumes of water to one volume of nectar base.
"Reasonably good color" means the color is fairly typical of nectar prepared from freshly extracted guava puree, or fairly typical of artificially colored guava nectar, and is free from browning or other abnormal color by any cause.
"Reasonably good flavor" means the prepared guava nectar has a flavor fairly typical of guava nectar prepared from freshly expressed guava puree and the flavor is practically free from bitter, oxidized, immature fruit, or other off-flavors and free from abnormal flavors of any kind; 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.
"Strawberry guava nectar base" means the nectar base made from the fruit of Psidium cattleianum guava plant.
