Dischem malt extract (as well as any other malt extract available in South Africa, unless expressly otherwise specified) is a food grade malt extract.
It is made by mashing food grade barley (with added amylase if necessary, depending on the diastatic power of the malt in the batch) at as high a temperature as possible, in order to get as many poly-saccharides as possible because these are what is required by the food industry.
When the barley has been fully converted the green wort is immediately fed into a vacuum evaporator (for LME) and subsequently a spray drier (for DME) without boiling. This is done at a fairly high temperature (which speeds up the process and reduces cost) resulting in Maillard reactions that darken the extract considerably.
The final product still contains the volatiles that normally boil off during the boil. As a result, beer brewed with this type of malt extract will contain unacceptable amounts of DMS (Di Methyl Sulphide) and many other compounds that will cause serious off-flavours. It is also still high in proteins (no boil, therefore no hot break!) which will make the beer brewed with it cloudy and instable.
Last but not least: because food grade malt extract is very high in complex sugars the finishing gravity after primary fermentation will still be sky-high (think 1.030 or more for a light blonde beer) and it will take at least three or four weeks of secondary fermentation for that to come down to 1.015 or so. If you bottle condition such a beer, gushers are the least you can expect. Exploding bottles are common.
Note that no amount of boiling can get rid of these drawbacks once the malt extract has been produced.
In summary, food grade malt extract can be used in minor quantities (say, up to 500 grams or so in a 25 litre batch) unless the beer has a lot of intense flavours that the DME can hide behind, in which case you can get away with a little more.
Brewing grade malt extract (LME and/or DME) is a different beast entirely. It is made using brewing grade barley, which is mashed at medium temperatures so as not to get too many poly-saccharides. Then the wort is properly boiled, which removes all sorts of unwanted substances from the wort that would cause off-flavours if they were left in, as well as hot-breaking out the proteins. Then the wort is cooled quickly (providing a proper cold break) before vacuum-evaporation or spray drying (for LME and DME, respectively) at a relatively low temperature.
The resulting malt extract will ferment out properly in a reasonable amount of time, not have an excess of DMS and other compounds causing off-flavours, and have a much cleaner profile in general, being based on brewing grade malt rather than food grade malt. The resulting beer will have an acceptable FG, colour, clarity and flavour profile. (Although a DME-only or LME-only beer will generally be rather unexciting, so the addition of specialty grains is recommended.)
