Abstract
Abstract Shaped protein containing food products such as rolled meat, sausage, cheese, or meat paste, are packed in wrappings such as nettings, skins or casings which, by virtue of contacting the products through a certain composition of an enzyme and a pH control agent, do not objectionably soften the products yet can be removed readily, without tearing off pieces of the products, after storage, cooling, deep freezing, thawing and/or cooking or other heat treatment of the products in the wrappings. The enzyme is one, e.g. pepsin, that does not act appreciably at the pH of the food product; the pH control agent in the presence of moisture creates a pH at which the enzyme is active.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
116 words
A PACKED SHAPED PROTIEN-CONTAINING FOOD PRODUCT SUCH AT MEAT, SAUSADGE, CHEESE, OR MEAT PASTE, COMPRISING A SHAPED MASS OF THE FOOD PRODUCT ENVELOPED IN A WRAPPING AND HAVING AT THE CONTACTING SURFACE OF SAID WRAPPING AND SAID MASS A COMPOSITION COMPRISING AN ENZYME THAT IS PARTICALLY INACTIVE AT THE PH OF SAID MASS AD A PH CONTROL AGENT THAT CREATES IN THE PRESENCE OF MOISTURE A PH AT WHICH SAID ENZYME IS ACTIVE, SAID ENZYME AND SAID PH CONTROL AGENT BEING PRESENT IN QUANTITIES SUFFICIENT TO INHABIT ADHESION OFTHE WRAPPING TO THE OOD PRODUCT YET SO LIMITED THAT THE ENZYME WILL ACT IN ONLY A LIMITED SURFACE LAYER OF SAID MASS IN THE PRESENCE OF MOISTURE.
Claim 2
Dependent Claim

A PACKED SHAPED PROTIEN-CONTAINING FOOD PRODUCT SUCH AT MEAT, SAUSADGE, CHEESE, OR MEAT PASTE, COMPRISING A SHAPED MASS OF THE FOOD PRODUCT ENVELOPED IN A WRAPPING AND HAVING AT THE CONTACTING SURFACE OF SAID WRAPPING AND SAID MASS A COMPOSITION COMPRISING AN ENZYME THAT IS PARTICALLY INACTIVE AT THE PH OF SAID MASS AD A PH CONTROL AGENT THAT CREATES IN THE PRESENCE OF MOISTURE A PH AT WHICH SAID ENZYME IS ACTIVE, SAID ENZYME AND SAID PH CONTROL AGENT BEING PRESENT IN QUANTITIES SUFFICIENT TO INHABIT ADHESION OFTHE WRAPPING TO THE OOD PRODUCT YET SO LIMITED THAT THE ENZYME WILL ACT IN ONLY A LIMITED SURFACE LAYER OF SAID MASS IN THE PRESENCE OF MOISTURE.
Claim 3
Dependent Claim
40 words
A product according to claim 1, said wrapping being a netting of yarns or threads forming an open mesh structure having meshes at intervals of from 1 to 5 mm. and having said composition impregnated therein and in dry condition.
Claim 4
Dependent Claim
25 words
A product according to claim 1, said wrapping being of a sheet material carrying said composition at least on the side thereof contacting said mass.
Claim 5
Dependent Claim
58 words
A product according to claim 1, said mass being of a meat or meat mixture having a surface pH in the range of about 5.8-6.5, said enzyme being a protease that is active in a pH range more strongly acid than said mass and said pH control agent comprising a normally solid water soluble acid or acid salt.
Claim 6
Dependent Claim
63 words
A product according to claim 1, said mass being of a meat or meat mixture having a surface pH in the range of about 5.8-6.5, said enzyme being a protease that is active in a pH range of about 8 to 11, and said pH control agent comprising a normally solid water soluble substance having an alkaline reaction in the presence of water.
Claim 7
Dependent Claim
44 words
A product according to claim 1, said mass being of a meat or meat mixture having a surface pH in the range of about 5.8-6.5, said enzyme being pepsin and said pH control agent comprising a normally solid water soluble acid or acid salt.
Claim 8
Dependent Claim
37 words
A product according to claim 1, said mass being of a meat or meat mixture having a surface pH in the range of about 5.8-6.5, said enzyme being pepsin and said pH control agent comprising citric acid.
Claim 9
Dependent Claim
71 words
A product according to claim 1, said mass being of a meat or meat mixture having a surface pH in the range of about 5.8-6.5, said wrapping being a netting of yarns or threads forming an open mesh structure having meshes at intervals of from 1 to 5 mm. and having said composition impregnated therein and in dry condition, said enzyme being pepsin and said pH control agent comprising citric acid.
Claim 10
Dependent Claim
122 words
A wrapping for packing a shaped mass of a protein containing food product such as meat, sausage, cheese, or meat paste, comprising a wrapping material adapted to envelope said mass and carrying at least on the side thereof that will contact said mass a composition comprising an enzyme that is practically inactive at the pH of said mass and a pH control agent that creates in the presence of moisture a pH at which said enzyme is active, said enzyme and said pH control agent being present in quantities sufficient to inhibit adhesion of said material to the food product yet so limited that the enzyme will act in only a limited surface layer of said mass in the presence of moisture.
Claim 11
Dependent Claim
122 words
A wrapping for packing a shaped mass of a protein containing food product such as meat, sausage, cheese, or meat paste, comprising a wrapping material adapted to envelope said mass and carrying at least on the side thereof that will contact said mass a composition comprising an enzyme that is practically inactive at the pH of said mass and a pH control agent that creates in the presence of moisture a pH at which said enzyme is active, said enzyme and said pH control agent being present in quantities sufficient to inhibit adhesion of said material to the food product yet so limited that the enzyme will act in only a limited surface layer of said mass in the presence of moisture.
Claim 12
Dependent Claim
40 words
A wrapping according to claim 9, said material being a netting of yarns or threads forming an open mesh structure having meshes at intervals of from 1 to 5 mm. and having said composition impregnated therein and in dry condition.
Claim 13
Dependent Claim
32 words
A wrapping according to claim 9, said material being a sheet material adapted to form a skin or casing on said mass and having said composition impregnated therein and in dry condition.
Claim 14
Dependent Claim
36 words
A wrapping according to claim 9, said material being a sheet material adapted to form a skin or casing on said mass and carrying at least on said side thereof a thin coating of said composition.
Claim 15
Dependent Claim
44 words
A wrapping according to claim 9, said enzyme being a protease that is active in a pH range of about 8 to 11, and said pH control agent comprising a normally solid water soluble substance having an alkaline reaction in the presence of water.
Claim 16
Dependent Claim
25 words
A wrapping according to claim 9, said enzyme being pepsin and said pH control agent comprising a normally solid water soluble acid or acid salt.
