What is the reason for the stickiness of mash during mashing?
The factor for this problem might be as listed below:
① The accessory active ingredient milling is not being taken care of efficiently. Too much big solids being developed that can not have a completely gelatinization inside the starch granule. It can not be proceed by the liquifying enzyme, so the mash thickness can not be decreased down.
② The bad excellent quality malt with negative liquifying capability. Or the rate of malt is not being elevated, while the Alpha-amylase prep work with lower job.
③ The price of malt to water is not reasonable. The grain cooker with much less water which produced a thick mash.
④ A faster home heating speed or much shorter temperature level keeping time when utilizing malt as Liquefied enzyme source. It decreased the procedure of water absorption along with swelling of starch; as well as likewise shorten the effective acting time of the enzyme.
⑤ Liquefaction enzymes were not made use of as recommended.
As some techniques could be accepted when got a thick mash:
① When discovering the thick mash or the difficult temperature level increasing throughout mashing, promptly consisting of some high temperature resistant amylase, it would certainly be fifty percent of the initial amount.
② Adding some hot water with temperature go beyond 80 ℃, enhancing the ratio of product to water to 6:1 or perhaps more as well as also improving the boiling time. Please do not include cold water that might cause starch regression. The grain mash need to be cooled down by blending before integrate the mash.
③ Including modest amount of food high quality salt hydroxide liquid to have alkaline hydrolysis. Prior to incorporated the mash, the PH has to be gotten used to 6.0 with phosphoric acid or lactic acid. This technique requires to be made use of extra diligently, a small assessment far better be done. That could will certainly affect the beer flavour.
