There is a big difference in regulation for factories and producers. And making fresh food preparations such as in a restaurant or butcher (Who sell for example jars with sauces or olives they make themselves). I would start by looking at the exact type of business model you have in mind, and perform market research as TwaBla has already mentioned.
What you can deduct from these existing businesses is the regulations they follow. For (takeaway) and (fresh) food preparation such as what I mention above. The rules and requirements involve similar regulations as restaurants. Restaurants usually follow the following steps:
- Find a location. Make sure the ''bestemmingsplan'' is allowed for restaurants. (The government should have specified that this venue is allowed for ''Horeca'' or ''Restaurant'' purposes.)
- Some cities require a specific additional permit ''exploitatievergunning'' or ''catering permit''
- You are likely required to follow training and obtain a certificate that you (or the manager of the business) are certified in handling food safely ''Sociale hygiene''
Starting a takeaway restaurant or catering, delicatessen. Would be much, much easier in my opinion than starting an own ''food factory'' or such type of firm. And if it performs well, you can always consider expanding production.
For restaurants or takeaway it is also important you consider the costs involved in proper inventory, staff costs and rent.
