DE586959C - Process for the production of vitamin-containing permanent preparations - Google Patents

Description

The vitamins, which are one of the most important nutritional factors, are against higher levels Temperatures, e.g. B. from 100 ° C, very sensitive, especially when an impact of the oxygen in the air is added. It is therefore not possible to contain vitamins Solutions, especially vegetable juices and extracts containing vitamins ο. like., through Evaporation in the air or even by injection into hot air according to the Krause process dry. Accordingly, prepares the production of long-term vitamin supplements great technical difficulties.

It has already been proposed to process vitamin-containing liquids of the above-mentioned type with blood fibrin, flour or blood coagulate to form a dough and to leave this in a thin layer at normal or slightly elevated temperature (up to 37 ^° C.) in the air

ao to dry. Notable damage the vitamins are avoided, however, the process alone is very time-consuming, and the danger that the dough will go moldy or start to rot is very great.

It is also known to produce an artificial dry milk by using skimmed milk mixed with chicken egg yolk and this emulsion evaporated to dryness, but it was It has not been recognized that the vitamins contained in milk and egg yolks are involved would be spared and are at least partly to be found in the end product. A good

Moreover, certain damage cannot be avoided with these procedures, because the Heat treatment takes quite a long time. "

After all, it was known to use milk and yeasts and • other substances containing vitamins similar substances forming a membrane-like skin to mix and the mass then to dry, if necessary at a low temperature; also solid floury waste to dry only after mixing with blood in order to prevent clumping, which could make drying more difficult.

In contrast, the present ER based ⁴ ^ invention on the finding that the in plant juices, vitamins contained extracts o. The like. A short-duration heating even at ioo ° and about tolerated, if care is taken that the air oxygen with the evaporation cannot come into contact with underlying liquid bodies. Therefore, if the vegetable juices o. The like. Protein-containing liquids that only coagulate in the heat, such B. skimmed milk, so you can finely distribute the mixture, for. B. by spraying in a hot air stream or on drum dryers, transform them into vitamin-rich dry products, because the individual liquid droplets or the thin liquid layers wetting the drying rollers immediately surround themselves with a coagulum membrane when heated, which is probably the escape of water vapor, but not

the access of air to the aqueous solution is permitted. Experience has shown that you can even temperatures above ioo °, as they are at Steam heated drum dryers occur under these conditions with no harm for who can use vitamins.

Avoid significant amounts of solid substances in the mixture to be evaporated the formation of the individual liquid droplets or layers against the Coagulate membranes protecting atmospheric oxygen and must therefore not be present. Likewise, the coagulation may only take place in the heat, i.e. after the distribution of the is to be evaporated liquid, which is why the addition of blood clot, also of Dried milk or blood does not produce the desired effect according to the invention.

ao The new process is accordingly characterized in that the vitamin-containing Juices or extracts with protein-containing liquids that only coagulate in the heat are homogeneous mixes and finely distributes it to dryness. Thereby one arrives in a way which is as simple as that Extraction of dry products from solutions that are insensitive to heat and oxygen Substances for long-term vitamin preparations that are characterized by a particularly high content of vitamins.

The skin-forming liquids that only coagulate in the heat can be made from skimmed milk or whole milk, including liquid blood or the like. The vegetable juices you can also use liquid animal products containing vitamins, such as B. Tran or Meat extract, add.

ι oo kg of whole milk, iookg rice bran extract and ι ο kg of vitamin-rich oil are mixed and splashed into a hot one Converted into a permanent product by air flow or by drying on drum dryers.

Example 2

100 kg of whole milk, 10 kg of tomato juice, 10 kg of egg yolk and 5 kg of meat extract are used Treated according to Example I.

Example 3

100 kg of fresh blood, 5 kg of tomato juice and 5 kg of cod liver oil are treated according to Example 1.

100 kg of carrots are washed and chopped and pressed. The press residue is taken up with water and pressed again. The combined pressed juices become mixed with 10001 skimmed milk and on Drum dryers brought to dryness.

Instead of carrot juice you can also use Onion juice or other vegetable juices, optionally mixed, can be used.

Claims (1)

Claim: Process for the production of vitamin-containing permanent preparations from plant juices, extracts and the like by drying with the addition of skin-forming protein-containing substances, characterized in that that the juices and the like can be mixed with protein-containing, which only coagulate in the heat Mixes liquids homogeneously and finely distributes them to dry.
