  BeeSource.com | POV | USDA | A Survey of American Honeys - 9. Effect of Storage on Diastase Content
This, and other evidence that showed variable effects of heating on diastase content, have led to modification of import reglations in West Germany, though at this time the new rules are not known.
The average diastase value of the cold storage samples was 22.0, while that of the portions stored at room temperature for an average of 13 months was 13.4.
Many of the samples with acceptable (to European importers) diastase values had values after storage of one to one and one-half years that would not be acceptable.

Malt diastase is a carbohydrolytic enzyme useful for digestive support and general nutrition support.
Malt diastase is characterized by the ability to break down amylose and other polysaccharides.
Malt diastase is active in the temperature range 20-50°C. Optimum pH range is 4-8.

A diastase (from Greek διαστασις, "separation") is any one of a group of enzymes which catalyses the breakdown of starch into maltose.
Today, diastase means any α-, β-, or γ-amylase (all of them hydrolases) that can break down carbohydrates.
The commonly used -ase suffix for naming enzymes was derived from the name diastase.

 [No title]   (Site not responding. Last check: )
The peculiarity of "diastase" is that it is a body containing nitrogen and having the power of rendering thick starch-paste liquid owing to the formation from it of the sugar maltose together with dextrin.
Other kinds of diastase occur, as for example in the saliva, and in the pancreas, and these forms, although they resemble in some respects the diastase contained in malt differ from it in other particulars.
Thus, the diastase of malt is not able to cause maltose to take up water and so be converted into dextrose, but both the diastase of the saliva and of the pancreas effect the hydration of maltose and change it into dextrose.

The names of seven of our producers together with their brands of honey were publicly paraded as the scourge to public health; HMF (hydroxy-methyl-fulrfuraldehyde) and Diastase activity found in honey were said not to confront with the acceptable limits of the directive 2000/110EC.
The indications of HMF and diastase found in honey were the result of changes that occur naturally in stored honey, whether at home or at the supermarket.
Furthermore HMF: and Diastase are indeed, not the result of contaminated honey products but rather, they are used throughout Europe and beyond as indicators of the longevity and freshness of honey.

 Apimondia - Apiacta - Article - The effect of heating on honey HMF and invertase
Diastase activity and hydroxymethylfurfural (HMF) are considered as the main parameters for evaluating the freshness and the heat and storage history of honey.
He suggests that diastase content is not useful in evaluating honey quality and especially heating while HMF is more appropriate and can 'provide all the information needed to estimate the total heat exposure of any honey'.
The amount of the enzyme depends on the age of the bee (BROUWERS 1982, BROUWERS 1983), the stage of the colony (HUANG et al.,1989), the nectar flow, the environmental conditions (WHITE, 1975) and the beekeeping practices (LAUDE et al.,1991).

 Carbohydrates - Maltose
At the point when the maximum starch content is reached, the seed growth is stopped by heating the grain to a temperature that stops growth but allows an important natural enzyme diastase to remain active.
Barley, once "malted" is very high in the type of starches that an enzyme called diastase (found naturally on the surface of the grain, just under the husk) can convert starch quite easily into the disaccharide called Maltose.
In this case the diastase enzyme is very specific and cuts the starch chain in units of two glucose which happens to be maltose.

In prolonging the gestation she forgot to introduce diastase at an earlier period, and the "memory" remained that it was not needed until the milk-period had passed.
Probably in all cases the oral or hypodermic administration of diastase during the last months of pregnancy would be of great benefit to the mother.
Therefore, in the treatment of cancer by pancreatic ferments injected into the blood it is most desirable that a pure trypsin alone without much diastase should not be employed, and if bad symptoms arise, these should be met by the giving of sterile hypodermic injections of 5 per cent.

Honey diastase activity is a quality factor, influenced by honey storage and heating and thus an indicator of honey freshness and overheating.
Although the minimal requirements for diastase activity in the Codex and the EU drafts are the same, in practice there is an important difference between the two: while the Codex norm refers to honey after processing and blending, the EU norm is valid for the whole retail honey.
Here too, as in the case with diastase, there is an important difference between the two norms: while the Codex norm refers to honey after processing and blending, the EU norm is valid for the whole retail honey.

 Value-added products from beekeeping. Chapter 2.
Since it is difficult to give a precise preservation limit for honey, due to the large variability of different factors, HMF and diastase are used as indicators of damaging treatment received by a honey during either processing or storage.
However, initial diastase contents vary in different honeys and have to be known for the fresh untreated material.
HMF is used more frequently as an indicator since its value is close to zero in very fresh honeys (other than a few tropical honeys) and its level increases with time and exposure to heat.
