This invention relates to the field of
food processing technology and discloses a completely additive-free, non-fried
convenience food and a multi-stage preservation process. The
convenience food includes a non-fried noodle cake and a
seasoning packet. The noodle cake is made solely from
wheat flour and drinking water, without any added food additives. The
seasoning packet includes chili oil and soup base packets, etc. The entire
system is free of
chemical preservatives, synthetic flavorings,
artificial colors, and chemical
flavor enhancers. This invention constructs a
plant-based synergistic preservation
system through a compound of natural spices, combined with a multi-stage preservation process of "gradient
humidity-controlled
drying, segmented temperature-controlled sterilization, aseptic filling,
inert gas replacement, and high-barrier packaging." This solves the industry pain points of additive-free convenience foods, such as difficulty in maintaining
shelf life at
room temperature, easy oxidation and deterioration, and weak
flavor. It achieves a room-temperature sealed
shelf life of ≥10 months, while ensuring good rehydration of the noodle cake and a chewy texture, and a harmonious and rich
flavor in the
seasoning packet. It is suitable for large-scale industrial production and meets the needs of healthy consumers.
