‘Goldach®’ is the perfect apple for the farm shop or the market: very attractive and suited for people suffering from the Mal d1 apple allergy, it also satisfies with its fruit quality.
The tree is easy to grow: The short branches are full of flower buds. Machine pruning can easily be applied. The vegetative growth is medium during the first few years, later it is weak. The tree stops the vegetative growth early in the season.
The yield is high and very regular. When thinned adequately, the fruit is big. The percentage of class 1 fruit is very high. Harvest can be completed in two pickings.
About 8-10 % of the Middle European population are suffering from an apple allergy. This allergy is triggered by certain proteins generally present in fruits of all apple varieties. There are different types of apple allergies. There are two main groups:
In many tests, ‘Goldach®’ has prooven to be the variety being tolerated very well by lots of ‘Mal d1’-apple allergic persons. It therefore can be named hypoallergenic and also be promoted as hypoallergenic.
We indicate that allergic persons should check on an individual basis if they tolerate the variety. In cases of heavy symptoms, medical supervision is strongly recommended. Lots of apple allergic persons are very grateful that there is the variety ‘Goldach®’ due to which they can eat fresh apples and thus regain some quality of life. You should not deny this your customers. They will appreciate being able to buy hypoallergenic apples. You might also reach pretty new groups of buyers.
That is a question of the concentration and of the type of allergy triggering proteins in the apple. ‘Mal d1’ proteins are present in all apple fruits. If its content is below a certain threshold, only weak or no allergic reactions are triggered.
According to first results, ‘Goldach®’ fruits have a low ‘Mal d1’ protein content and therefore trigger only weak or no allergic reactions.
