A process for the treatment of pre-dried animal meal yields products containing small peptides, resulting from combining methods of alkaline liquification and proteolytic enzyme treatment. These peptides are highly suitable for inclusion in animal feeds or edible food products.

Process for treating pre-dried animal meal

There is disclosed the sterilization of infectious hospital waste to generating a residue which is suitable for disposal. The invention comprises a first step of digestion at elevated temperatures and under highly alkaline condition for one to three hours. This step is combined with the necessary comminution, e.g., grinding, pulverizing and the like, to ensure substantially complete liquefaction of the wastes. The liquid reaction products from the first step are neutralized to a slightly alkaline pH, e.g., 7.5-9.5, and the waste is then subjected to enzymatic digestion with a suitable proteolytic enzyme for a short period of time. Preferably this proteinase treatment is combined with further comminution to further reduce any oversized particles that may remain in the waste following the first treatment. The enzymatic treatment is continued for a period from 30 to 90 minutes at temperatures most suitable for the selected enzyme and results in substantially complete hydrolysis of the proteins in the waste. Finally, the treated waste from the second step of enzymatic digestion is inoculated with from 8 to 20 percent of a sterilant, preferably sodium hypochlorite and the pH is reduced to an acidic pH from about 3 to about 6, and the inoculated residue is held for an extended period of time, from about 30 to about 120 minutes at an elevated temperature to ensure essentially complete sterilization of the liquid which can be concentrated or dried for disposal.

P-carboethoxy ammonium ascorbate as an anti-thrombotic compound and method of making same from ascorbic acid and ethyl p-amino benzoate.

Anti-thrombotic compounds

Methods for reducing thrombotic tendencies in a host by administering a therapeutically effective amount of p-carboethoxy ammonium ascorbate, p-carboglyceryloxy ammonium ascorbate or a mixture of esters of para amino benzoic acid and ascorbic acid.

Methods for administering anti-thrombotic compounds

A solution of L-ascorbic acid and a solution of para amino benzoic acid are mixed and the mixture evaporated to permit recovery of a solid compound. The compound is administered to a host to reduce thrombotic tendencies.

Mixture of esters of para amino benzoic acid and ascorbic acid

Sources of protein, such as residues and waste products from processing fish, poultry, pork and beef as well as single cell microorganisms, are hydrolyzed to provide liquid products containing substantially all of the component amino acids, lipids and phosphorus in metabolically useful form. The process involves a brief alkaline treatment with heat (120.degree.-170.degree. F.) and alkali (pH 12 or above) which facilitates liquefication and enhances susceptibility to subsequent enzyme hydrolysis with bacterial proteinase at elevated temperatures (100.degree.-140.degree. F.). Cell rupture and protein denaturation occur during alkaline treatment and permit and facilitate the enzyme to rapidly break down the intact proteins to smaller, more soluble molecules. The product may be preserved with various acids at a pH of 3.8 to 4.2.
