Abstract
The present invention provides a food packaging machine comprising a packaging material supply module, a food supply module, a filling module. The food packaging machine further comprises a hardware data processor operably connected to the packaging material supply module, operably connected to the food supply module, so operable to create a food data transaction, and operably connected to a network data processing system. The hardware data processor is operable to send the food data transaction to the network data processing system for the data transaction to be appended to a packaged food production data hash tree. The present invention further provides a system for packaging food comprising a plurality of food packaging machines as well as methods for tracking food data transactions in a food packaging machine and in a system for packaging food.
