Abstract
A process for producing a preserved fish food from live fish food wherein the live fish food such as brine shrimp, tubifex worms, earthworms, plankton and the like are placed in an anhydrous liquid desiccant such as propylene glycol and allowed to stand for a sufficient period of time to dehydrate the live fish food to an equilibrium level, and after removing the supernatant liquid, a preservative liquid may be added to the preserved fish food to produce a storage stable, preserved fish food, and the products produced by the process.
Claims11
A process for producing a preserved fish food from live fish food material naturally sized for feeding to aquarium fish comprising providing a quantity of live fish food, draining any excess water from the live fish food, mixing the drained live fish food with 17-50% by weight of the fish food of substantially anhydrous liquid propylene glycol for dehydrating the live fish food, allowing the mixture to stand for a sufficient period of time to reach a substantially equilibrium concentration of water in said liquid, draining said liquid from the fish food, and adding approximately 10-20by weight based upon the weight of the fish food of anhydrous propylene glycol.
A process for producing preserved brine shrimp comprising providing a quantity of live brine shrimp in water, draining the water from the live brine shrimp, mixing the drained live brine shrimp with an approximately equal weight of substantially anhydrous propylene glycol, allowing said mixture to stand at room temperature for sufficient time to dehydrate the brine shrimp, removing the supernatant liquid from the brine shrimp, and adding to the brine shrimp approximately 10-17% by weight of the dehydrated brine shrimp of fresh substantially anhydrous propylene glycol preservative.
