[0023] For the processing of palm kernel meal, see the step flow chart figure 1 .

[0024] 1) Take 1kg of palm kernel meal through sieving, winnowing, and permanent magnet, then remove the impurities in it, and crush it to about 125 mesh by an ultrafine grinder.

[0025] 2) After adding 5 times water to the ultra-finely pulverized palm kernel meal, stir it evenly, enter the high-pressure homogenizer, and process it at 1000 bar.

[0026] 3) The material after high-pressure homogenization is added with 1 time water, and mixed evenly, enters the ultra-high-pressure homogenizer, and processed at 1800bar.

[0027] 4) Heat the two homogenized materials to 63°C, adjust the pH to 3.8 with 10% calcium hydroxide solution or 10% sulfuric acid solution, and enzymatically hydrolyze at a constant temperature for 20 hours under stirring.

[0028] 5) After the enzymolysis is completed, the solid is separated by solid-liquid separation, and the solid is directly dried to obtain a dry ...

Abstract

The invention relates to a production method of a forage-use mannose oligomer. Raw materials adopt materials rich in the mannose oligomer. The production method comprises the following steps: a, removing impurities; b, carrying out ultramicro pulverization, wherein fineness requirement of the pulverized material is that 95% of the pulverized material can pass 0.15mm; c, carrying out high pressure homogenizing at a pressure lower than 20000psi; d, carrying out ultrahigh pressure homogenizing at the pressure of 20000-60000psi, so that the material is uniform and floccular; e, carrying out enzymatic hydrolysis by utilizing beta-mannase and other non-starch polysaccharide enzymes under the conditions that the temperature is 40-70 DEG C, pH is 3-5, addition amount of the beta-mannase accounts for 0.05-1% of the amount of the material and enzymatic hydrolysis time is 4-48 hours; f, carrying out filter pressing for separating solid and liquid; g, directly drying the solid to obtain dry residue; h, carrying out spray drying on the liquid, so that dry powder is obtained; and i, uniformly mixing the dry residue with the dry powder, and then smashing, so that the finished product is obtained. The production method of the forage-use mannose oligomer has the advantage that the raw material from which mannose is difficult to extract can become a material from which the mannose is easy to extract.

Description

[technical field] [0001] The invention relates to a production method of mannose oligosaccharides for feed. [Background technique] [0002] The existing mannose oligosaccharides are mainly derived from the cell walls of konjac and brewer's yeast. Konjac is not suitable for the feed industry due to its expensive raw materials and high product prices; the mannose content contained in the yeast cell wall is relatively low, and its production and application are relatively limited. [0003] Palm kernel meal, coconut meal, coffee grounds and other agricultural product processing by-products not only have high mannose content, but also have a wide range of sources and are cheap, so they are a good source. [0004] Due to the hard structure of these mannose-derived raw materials, it is difficult to release mannose by common methods, which also limits the further utilization of these raw materials. At present, they can only be wasted or simply used as one of the feed materials, and...
