Description

SPECIFICATION Protein concentrates and food-preparations containing bioactive substances and a process for the preparation thereof The invention relates to protein concentrates and food-preparations containing bioactive substances as well as a process forthe preparation thereof.

It is known that in the organism the inorganic salts, such as the trace elements, themselves are hardly absorbed and hardly utilized. However,foran appropriate function of the enzymesthe presence of the trace elements is by all means necessary. The active biological transport of the trace elements is assured bythe so called carrier molecules. These are proteins, e.g. albumins, globulins, metalloproteins and soon with which the trace elements form complexes.

The side effects of very many ofthe pharmaceutical products used nowadays occur due to the fact that the concerning pharmaceutical productforms a complex with various metal ions and extracts them from the organism. Thus afterthe treatmentwith pharmaceutical products is finished, the trace elements have to be replaced to an increased degreeforthe regeneration of the organism.

All over the world experiments are carried out in orderto prepare protein food-preparations containing trace elements. Such a product is e.g. "Parkelp" produced by the Stauffer Chem. Company which is a tablet prepared from Californian brown alga. The disadvantage of the product resides in the fact that its iodine content is too high and thus there is the danger of a iodine overdosing.

The aim ofthe invention is the elaboration of a product which contains the trace elements indispensable for the organism in an appropriate, easily absorbing form.

The invention is based on the recognition that excellent products corresponding to the above aim can be prepared by admixing natural mineral and medicinal waters with natural substances containing protein.

That is the invention relates to protein concentrates and food-preparations containing bioactive substances consisting of animal and/or plant proteins and metal ions of mineral or medicinal water,furthermore optionally of other additives. Furthermore the invention relates to the preparation of these protein concentrates and food-preparations by admixing substances containing animal and/or plant protein with mineral or medicinal water, reacting the mixture under heat treatment or at ambienttemperatu re and then optionallyafterthe addition of additives by thickening and drying.

The natural substances containing protein, applic ableforthe preparation ofthe protein concentrates and food-preparations according to the invention can be of animal origin, such as e.g. animal blood, blood plasma, haemoglobin, animal organs, e.g. milt, liver, kidney, pig dorm and soon, white of egg, apicultural products, e.g. honey, propolis, pollen, royal jelly and soon. Furthermore, substances of plant origin, too, can be used which also contain protein, thus e.g. pea4lour, wheat4lour, fruit, vegetable, fruit orveget- able juices and so on.Amixtureofthe above substances, too, can be used.

The above natural substances containing protein can be used in native form, e.g. in pulpifiedform bust a preconcentratecan be prepared from them, too.

In the course ofthe process the native substances containing protein orthe preconcentrate obtained from them are admixed with mineral or medicinal water and reacted. Instead of mineral or medicinal water river, lake or sea water, too, can be used. The reaction is carried at a temperature between 0 and 140"C. A reaction at a low temperature takes a long time, therefore it is suitable to work at an increased temperature. If one uses a temperature over 1 00 C, one has to work under pressure.The temperature chosen depends on the properties of the used substances containing protein and the product to be producted. Advantageous is a temperature range between room temperature and 90"C. If the proteins are to be maintained in native form, the reaction is performed at a relatively lowtemperature.The time of the reaction can vary between some minutes and several hours.

The ratio of the substance containing protein and the metal ions can vary between wide limits. The quantity of chromium can be between 10-9to 10-8 g, that of vanadium, molybdenum, cobalt and nickel can be between 1O6to 10-7 g, that of zinc and copper can be between 10~7to 10-3 g,that of iron can be between 1 0-7 to 1 of2 and that offluorine can be between 10-7 to 1 of6 g per one 9 of protein. The metal ion content can be increased by adding salts.

In orderto increase the hydrophility ofthe protein concentrate sodium hydrogen carbonate can be added and the formation of precipitate can be increased by ethanol.

The mixture containing the obtained protein-metal ion complex includes all the useful natural substances which originally can be found in the substance containing protein and, resp., in the mineral water what renders possiblethatthese elements are well absorbed and utilized in the organism.

The obtained mixture can be used itself as human or animal food-preparation or one can form a concen trate from it. It can be admixed with further additives and granulated or dried and formed to tablets, according to the aim of application. As additive auxiliary agents used fortabletting, substances containing fibres, such as wheat bran, cereal milling products and soon can be applied.

The protein concentrates and food-preparations of the invention are suitable forthe treatment of patients or animals suffering from different deficiency diseases, e.g. from iron deficiency or other trace element deficiency. Thefood-preparation prepared from the plasma proteins is particularly advantageousforthe dietary feeding of patients suffering from arthritis, namely, the product does not contain any purine and pyrimidine derivatives, DNA-residues, it contains, however,the bioactiveelementsveryimportantfor the organism.

The solution according to the invention is demonstrated by the following examples without limiting the application to them.

Example 1 To 1001 of cattle blood plasma 51 of Harkany medicinal water (temperature: 60 C) are added and heated to 75C, and stirred at this temperature for 10 minutes. The proteins reacted with the substances of the medicinal water and precipitated are filtered off and dried, thus 9 kg of a protein concentrate are obtained which contains the substances ofthe medicinal water. The obtained protein concentrate is used as tablet or in an otherform as food-preparation. The filtrate still contains 0.2 to 0.3% of protein and unreacted trace elements. This solution can be utilized as cosmetic parent substance or as animal foodpreparation.

Example 2 One proceeds as described in Example 1, with the difference that to the mixture of plasma and medicinal water 1 kg of sodium hydrogen carbonate is added.

The hydrophilic property of the obtained protein concentrate is better than that ofthe product obtained according to Example 1.

Example 3 One proceeds as in Example 1, with the difference thatthe protein is precipitated from the plasmamedicinal water mixture itself or in the presence of sodium hydrogen carbonate with the help of 2001 of ethyl alcohol.

Example 4 100 kg of pork liver in pulpified state are admixed with 101 of Pared mineral water and stirred forfurther 30 minutes. Then 1501 of ethyl alcohol are added, the precipitate separated is filtered off and dried at a temperature u nder 80"C. Th us 20 kg of liver powder enriched with the substances ofthe Pared mineral water are obtained which is used as food-preparation.

Example 5 One proceeds as described in Example 4, with the difference that before the alcohol precipitation 2 kg of sodium hydrogen carbonate are added to the mixture.

Example 6 One proceeds as in Example 4, with the difference that no alcohol is added to the reaction mixture and it is heated to 90"C. The obtained solid substance is used itself or dried as food-preparation.

Example 7 One proceeds as in Examples 4,5 or 6, with the difference that instead of liver pork beef milt is used.

Example 8 To a mixture of 1 kg of dried camomile, 0.5 kg of sumac and 2 kg of lime-blossom 251 of Hajduszobosz16 medicinal water are added the temperature of which is 70 C. The mixture is covered and ailowed to stand for 30 minutes, then filtered off. To this filtrate 5 kg of honey are added, and the obtained substance is used asfood-preparation enriched with the elements ofthe Hajduszoboszl6 medicinal water.

Example9 To 1 kg ofthe product prepared as in Example 2201 of water of medicinal spring II ofthe Budapest Lukacs bath are added. The mixture is maintained at 1 for one hour. To the obtained solution an extract prepared from 51 of Hajduszoboszl6 medicinal water and 1 kg of rape flower, and 5 kg of honey are added. A drink containing the useful substances ofthe components is obtained.

Example 10 1 kg of beef liver pulp is admixed with 100 ml of He'viz medicinal water and stirred for 1 hour, then 1.5 1 of percent ethyl alcohol are added andthoroughly admixed. The precipitate separated off is filtered off, dried and used as food-preparation.To the filtrate a solution prepared 5 g of propolis and 200 ml of ethyl alcohol, then 5 g of pollen and 1.5 kg of honey are added.After homogenization an excellentfood-prepa ration is obtained which can be consumed after diluting with water Example 11 10 g of sunflower lecithin containing 50% of phosphatide are swollen in 11 of Pared mineral water, then 500 g of honey are added into which previously 2 g of royal jelly were admixed. Then the mixture is heated to 60do. After cooling-off the substance is used as food-preparation.

Example 12 To 951 of apple juice 51 of medicinal water of the Budapest Lukacs bath are added and stirred for 30 minutes, then filled and put into circulation in a mannergenerallyused in the production of refresh ment drinks. The product contains 80,us/1 offluoride.

Example 13 From 100kg of wheat flour bread is prepared in a mannerknown perse and 10% of the water phase are replaced by medicinal water of the Lukacs bath. Thus bread enriched with the elements of the medicinal water is obtained.

Example 14 To 100 kg of fruit 101 of Parád mineral water are added, and from the mixture jam is prepared in a mannerknown perse. Afood containing trace elements useful for the organism is obtained.
