The invention discloses a normal-temperature
supplementary food suitable for infants at all stages and a preparation technology, and belongs to the technical field of infant
supplementary food. Aiming at the problems of insufficient staged matching, dependence on additives,
nutrition loss and the like of the existing
complementary food products, a dynamic staged regulation and control scheme is provided: the chewing development requirements of 6-18-month-old infants are met through
food material particle grading matched with the month old and stepped adjustment of a
nutrition ratio. A multi-section rotary
sterilization process is innovatively adopted, gradient
temperature control, pressure regulation and rotary
power control are combined, normal-temperature preservation for more than or equal to 12 months is realized under the
preservative-free condition, the
solid content is more than or equal to 85%, and the
vitamin retention rate is more than or equal to 92%. An
aluminum high-barrier bowl sterile filling process is matched, an industrial production
standard system is established, the feeding error is smaller than or equal to + / -1%, and the product percent of pass is larger than or equal to 99.8%. The product has staged
nutrition adaptability, edible safety and convenience, effectively solves the problem of preparation of
complementary food for parents in workplaces, and meets the special requirements of infants on
food texture and nutrition absorption in each development stage.
