Abstract
Abstract A process for preparing flesh-containing products such as roast fowl and butcher's meat and pork-butcher's products such as hams, pies, sausages or other products, wherein pieces of raw or previously treated flesh and additive substances corresponding to the desired products are placed and enclosed under vacuum within vessels giving the desired products their final shape, the pieces of flesh, put into the vessels, undergoing a repeated vacuum action for de-aerating same.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
114 words
A method of preparing flesh containing products from raw pieces of flesh, comprising, subjecting the raw pieces of flesh to a continuous mechanical treatment under alternating vacuum action and inert gas injection for breaking the muscle-fibres of the flesh, placing the pieces of flesh within vessels giving the desired products their final shape, subjecting the said pieces of flesh placed within the vessels to a series of expansion and compression treatments by alternating vacuum action and inert gas injection for a time sufficient to complete the breaking of the muscle-fibres and for fully de-aerating the pieces of flesh, and sealing under vacuum the said vessels and cooking said pieces of flesh within said vessels.
Claim 2
Independent Claim
114 words
A method of preparing flesh containing products from raw pieces of flesh, comprising, subjecting the raw pieces of flesh to a continuous mechanical treatment under alternating vacuum action and inert gas injection for breaking the muscle-fibres of the flesh, placing the pieces of flesh within vessels giving the desired products their final shape, subjecting the said pieces of flesh placed within the vessels to a series of expansion and compression treatments by alternating vacuum action and inert gas injection for a time sufficient to complete the breaking of the muscle-fibres and for fully de-aerating the pieces of flesh, and sealing under vacuum the said vessels and cooking said pieces of flesh within said vessels.
Claim 3
Dependent Claim
23 words
A method according to claim 1, wherein said inert gas is carbon dioxide under a pressure at least equal to the atmospheric pressure.
Claim 4
Dependent Claim
34 words
A method according to claim 1, further comprising the step of placing a cover made from semi-rigid material onto said pieces of flesh disposed inside of said vessels before sealing the latter under vacuum.
Claim 5
Dependent Claim
15 words
A method according to claim 3, wherein said cover has a plurality of bored holes.
Claim 6
Dependent Claim
38 words
A method according to claim 1 further comprising the steps of placing a cover provided with a plurality of holes onto said pieces of flesh disposed inside each of said vessels before the steps of expansion and compression.
Claim 7
Dependent Claim
68 words
A method according to claim 1, comprising the step of placing a semi-rigid cover onto said pieces of flesh within each of said vessels, said cover being deformable at its periphery by means of a pleated formation, and then sealing said cover under vacuum onto said vessel for closing same tightly whereby said cover is closely applied onto the conditioned product after the atmospheric pressure has been restored.
Claim 8
Dependent Claim
75 words
A method according to claim 1, consisting, prior to filling said vessels, in placing into each of the vessels a thin flexible sheet made from plastic material, perforated with many small holes and the edges of which extend beyond the edges of said vessels and after filling of said vessels with the pieces of flesh, in folding down over the flesh the edges of said sheet so that said sheet wraps said pieces of flesh.
Claim 9
Dependent Claim
30 words
A method according to claim 1, wherein after said cooking said vessels are placed within an outer overpacking which is tightly closed after having filled it with an inert gas.
