Abstract
Abstract Disclosed is a process for extracting and stabilizing juice from leaves of the aloe vera plant. The gel is removed by trimming the rind and aloin layer from the leaf and the remaining gel digested under ultraviolet radiation at ambient temperature to produce a biologically sterile and chemically stable extract of composition having characteristics similar to fresh aloe vera juice.

Total Claims: 10
Claim 1
Independent Claim
62 words
THE PROCESS OF PREPARING AN EXTRACT OF ALOE VERA COMPRISING THE STEPS OF: A. CUTTING THE RIND AND ALOINS OF AN ALOE VERA LEAF FROM THE GEL, AND B. AGITATING THE GEL UNDER U.V. RADIATION IN A DIGESTION LIQUID CONTAINING AMINE, PHOSPHOROUS IONS AND POTASSIUM IONS WHILE MAINTAINING THE PH OF THE LIQUID IN THE RANGE OF ABOUT 3 TO ABOUT 4.5.

Claim 3
Dependent Claim
56 words
The process of preparing an extract of aloe vera comprising the steps of: A. physically separating the rind and aloins of an aloe vera leaf from the gel, and b. agitating the gel under U. V. radiation in a digestion liquid containing glycine, citric acid, ascorbic acid, potassium chloride, potassium gluconate, a surfactant and phosphoric acid.
Claim 4
Dependent Claim
56 words
The process of preparing an extract of aloe vera comprising the steps of: A. physically separating the rind and aloins of an aloe vera leaf from the gel, and b. agitating the gel under U.

Claim 5
Dependent Claim
114 words
The process of forming an attenuated extract of aloe vera juice comprising the steps of a. cutting the leaves from an aloe vera plant, b. sterilizing said leaves by washing in a chlorine solution, c. drying said leaves, d. physically removing the rind and aloins from the gel under sterile conditions, e. placing the gel in a sterile container, f. adding a digestion liquid comprising citric acid, ascorbic acid, glycine, potassium chloride, and potassium gluconate, g. agitating the resultant mixture, h. adding phosphoric acid and a surfactant to the mixture, i. agitating the resultant mixture while exposing said mixture to U.V. radiation for about four hours, and j. filtering residual cellulose from the mixture.
