Abstract

The present invention relates to a method for producing pentose hydrolysates from pentosane-containing raw materials which have a higher purity as well as a higher xylose content. This method can be used for increasing the xylite production rate and comprises processing the hydrolysate in the following manner. This method uses as pentosane-containing raw materials the distiller's grain from the brewers' industry. During a first step, the distiller's grain having a natural humidity is submitted to a liquid-phase disintegration in a disc mill comprising a vibrator with an oscillation frequency of between 10 and 50 Hz. The disintegration can also be carried out in an ultrasonic apparatus with waves at a frequency of between 22 and 44 kHz or in a rotary-pulse apparatus having a rotor rotating at 3000 r/min., wherein the disintegration is carried out for a duration of 1 to 15 minutes and the solid phase is further separated from the liquid suspension. A second step comprises carrying out a high-temperature scrubbing during which the solid phase is mixed with water according to a ratio of 1 : 5-8. The mixture is maintained at a temperature of between 140 and 160 °C for 10 to 30 minutes while being periodically stirred. The solid phase is then separated and submitted to hydrolysis using a 0.5-2.5 % solution of sulphuric acid for a duration of between 2 and 4 hours and at a temperature of between 100 and 120 °C. This method ensures the protection of the pentosanes against the acidic decay during the refining process of the vegetal raw materials. The xylose concentration relative to the total amount of sugars in the hydrolysate increases from 57 % (when the starting mixture is distiller's grain) to 84-87 %, while the arabinose content is divided by two (from 30 to 13-17 %). This method further produces a proteinic paste containing up to 40 % of raw proteins while maintaining the nutritional values of the distiller's grain components.

Beer is a waste product and 5 is used as a result of the use of a friendly barley serving. For 100 kg of wort, 115-130 kg of humid produce. Depending on the method of isolation from the beer wort, the beer bar has a nicely shaped appearance, it is easy to take care of it, but it’s a good result. The beer industry contains about 32% of easy-to-use polysaccharides (LHP) and 11% of easy-to-drink cans (ΤGP). Other than that, in the composition of the beer house, there are halls, lignin, non-carbohydrate components, including white, fat, whole.

It is known, for example, of a method of producing good white food from dry beer (Patent Federal Law 1677670, Α 23 Κ 1/06, 1977)

For the production of food containing 15% by weight of protein, the dry beer slurry is spared by grinding or adding to the protein to be removed from the whey, then it is cleaned. Protein content can be increased by up to 30%, due to more small land.

It can be separated by vibrating on the fiber, which will quickly return to the specialized road and use a little more fluid and more fluid. This liquid is divided into a liquid fraction, which can be used for food purposes, for example, for mixing dough and white meat. The method of production of fortified protein products (US Patent Ν ° 5135765 Κ 23 Κ 1/10, 1992) is excluded, which accounts for a mixture of 77.5% of the humidity that is mixed with moisture. . The one mixture is screened through a sieve with a size of 0.4-1 mm. After 0 repetition of the indicated operations, the absorbed material and protein material with a content of proteins of 50.8% are extracted. From the literature, there is no known use of beer in the quality of potential raw materials for the production of potent liquids that contain benefits.

It should be noted that in contrast to traditional types of potential raw materials, for beer there is a high content of non-carbohydrate. In fact, in the old world, 80% of the protein is retained, taken for the processing of grain, since the destruction of the protein substances is caused by the activity of the enzymes, Therefore, with acidic hydrolysis, which is necessary for the production of pentazens, proteins are decomposed by aminoxides, which are the result of melancholytic substances. This leads to a deterioration in the efficiency of the hydrolysis and reduces the yield of useful target products - the use (strength) and protein. When the raw materials are handled mechanically, the removal of the main mass of impurities that interferes with the subsequent stages of the process is avoided.

The washed phase is fortified with hemicellulose polysaccharides, which are then hydrolyzed by the diluted acid for the preparation of a beneficial hydrolyzate. To ensure a safe mode of disintegration of a beer in the region is necessary to ensure the possibility of a larger separation of non-carbohydrates from raw materials This helps maximize the reduction of the cost of raw materials with separated non-carbon components and the reduction of the whiteness of the product.
