Furthermore, such powders have a nutritional structure in which they are not qualitatively better than that of the starting material, or they exhibit such organoleptic characteristics that they are of very limited use in terms of products for human consumption, or are even prohibitive.

Embodiment 1

[0053] In a turbo reactor A, in which the bladed rotor rotates at a peripheral speed of about 30m / s, and in which the inner wall is kept at 150°C, a A quill-based animal meal fluid (about 7% moisture). At the same time, a 130-V (volume) hydrogen peroxide solution was continuously fed through the opening 6 and the opening 10 at a flow rate of 50 liters / hour.

[0054] Directly at the inlet of the turbo reactor A, the animal meal fluid is mechanically dispersed into very fine particles, which are immediately centrifuged against the inner walls of the turbo reactor itself, where they form a Dynamic tubular laminae.

[0055] At the same time, the aqueous hydrogen peroxide solution entering through the opening 6 is mechanically and finely atomized by the blades 9 of the rotor 8, which also easily produce a centrifugal effect on the obtained very small droplets. . In this way, they are introduced into the dynamic tubular lamina of the animal meal particles with which they interact...

Embodiment 2

[0064] In a turbo reactor A, in which the bladed rotor rotates at a peripheral speed of about 30 m / s, and in which the inner wall is kept at 130° C., a Fish based animal meal (about 7% moisture). At the same time, a 130-V hydrogen peroxide solution was continuously fed through opening 6 and opening 10 at a flow rate of 50 liters / hour.

[0065] Subsequent steps of the method were performed as described in Example 1 above.

[0066] The animal meal obtained had a moisture content of about 7% and when analyzed it showed a ratio of total nitrogen to ammoniacal nitrogen of 35 relative to the starting value of 60, the amount of total nitrogen remaining essentially the same as that of the starting food constant.

[0067] The powder is substantially odorless and sterilized from a microbiological point of view.

[0068] Thus, the ratio of total nitrogen to ammoniacal nitrogen was shown to be considerably reduced, and subsequent analysis of primary amines according to the Van Slyke me...

Abstract

Process for treating animal meals in order to improve their amino acid availability, comprising the steps of: a) feeding a continuous flow of animal meal to a turbo-reactor so as to disperse said continuous flow of animal meal in a flow of animal meal particles, b) feeding into said turbo-reactor, cocurrently with said animal meal flow, a continuous and finely divided flow of a reactant consisting of a concentrated aqueous hydrogen peroxide solution , c) centrifuging said animal meal particles and said reactant against the turbo-reactor inner wall heated at a temperature of at least 1000C, with formation of a thin tubular fluid layer, d) reacting said animal meal and said reactant within said thin layer while progressing in contact with said inner wall of the turbo-reactor, e) continuously discharging a flow of treated animal meal, having a humidity content of 30-50%, f) sending said flow of treated animal meal on to a maturation step at 60-90 DEG C / 30 min - 20 h and to a subsequent drying step to bring the humidity content of the end animal meal to 5-10%.

Description

technical field [0001] The invention relates to the field of food and livestock industry, in particular, the invention relates to a method for processing animal meal to obtain a product characterized by improved availability of amino acids. Background technique [0002] The production of animal meal for the production of high protein content feed for animal feeding is well known. Such powders are usually prepared according to traditional cooking and grinding techniques, followed by a drying step to give them the typical characteristics of powders. [0003] Such animal meals are primarily obtained from starting materials such as fish, plumes, feathers, or other sources rich in protein or other desired nutrients. [0004] They are unsuitable for human consumption as traditional methods leave the powder with the original enzymatic taste - in some cases a repulsive taste - and they are difficult to use and market as food for human consumption. [0005] Furthermore, from a nutr...
