A method for processing frozen food product into a package, the method comprising: providing a frozen food product; providing a transfer system converting the frozen food product to a pumpable state by using a mechanical process to slice, smash, or chop the frozen food product into frozen granular pieces, thereby creating a pumpable frozen food product; in response to the converting the frozen food product to a pumpable state, processing the pumpable frozen food product comprising: rapid heating of the pumpable frozen food product for a predetermined time that is less than or equal to 4 minutes until the pumpable frozen food product reaches a predefined temperature that is above 95°C, thereby creating a processed food product, wherein rapid heating is realized by using electromagnetic heating from an electromagnetic source; delivering the processed food product at the predefined temperature into a package, and after creating a processed food product and before delivering the processed food product at the predefined temperature into a package: holding the processed food product at the predefined temperature for a predetermined time that is less than 2 minutes; determining, using a computer, whether to process the processed food product either aseptically or hot filled; in response to determining to process the processed food product aseptically: cooling the processed food product until the food product reaches a predetermined temperature that is below 35°C; and filling a flexible package with the cooled processed food product; in response to determining to process the processed food product hot-filled, directly delivering the processed food product into a package. providing a frozen food product; providing a transfer system converting the frozen food product to a pumpable state by using a mechanical process to slice, smash, or chop the frozen food product into frozen granular pieces, thereby creating a pumpable frozen food product; in response to the converting the frozen food product to a pumpable state, processing the pumpable frozen food product comprising: rapid heating of the pumpable frozen food product for a predetermined time that is less than or equal to 4 minutes until the pumpable frozen food product reaches a predefined temperature that is above 95°C, thereby creating a processed food product, wherein rapid heating is realized by using electromagnetic heating from an electromagnetic source; delivering the processed food product at the predefined temperature into a package, and after creating a processed food product and before delivering the processed food product at the predefined temperature into a package: holding the processed food product at the predefined temperature for a predetermined time that is less than 2 minutes; determining, using a computer, whether to process the processed food product either aseptically or hot filled; in response to determining to process the processed food product aseptically: cooling the processed food product until the food product reaches a predetermined temperature that is below 35°C; and filling a flexible package with the cooled processed food product; in response to determining to process the processed food product hot-filled, directly delivering the processed food product into a package. holding the processed food product at the predefined temperature for a predetermined time that is less than 2 minutes; determining, using a computer, whether to process the processed food product either aseptically or hot filled; in response to determining to process the processed food product aseptically: cooling the processed food product until the food product reaches a predetermined temperature that is below 35°C; and filling a flexible package with the cooled processed food product; cooling the processed food product until the food product reaches a predetermined temperature that is below 35°C; and filling a flexible package with the cooled processed food product; in response to determining to process the processed food product hot-filled, directly delivering the processed food product into a package.
