This invention discloses a low-
sugar Gastrodia elata,
lotus seed, and lily
bulb instant porridge and its industrial production process, belonging to the field of functional instant cereal
food processing technology. The instant porridge is made by compounding a limited
mass of
solid material components with
purified water. The
solid materials include various grains, edible auxiliary materials, chopped nuts,
Gastrodia elata ultrafine
powder, and a limited amount of low-
sugar sweetener. This invention uses a
compound organic acid color-protecting process, edible rice
wine to complex and deactivate off-odors, and a low-temperature
vacuum drying process to prepare
Gastrodia elata ultrafine
powder, which can improve the sensory
aroma of
Gastrodia elata and reduce the high-temperature loss of effective substances during
processing. The production process includes
raw material sorting, precise constant-temperature water-controlled soaking of grains, premixing of
Gastrodia elata powder, quantitative canning, high-temperature hot filling and sealing under normal pressure with slight negative pressure, segmented variable-speed rotary sterilization, back-pressure cooling, and light inspection with inkjet coding before warehousing. This invention requires no additional synthetic stabilizers or preservatives throughout the entire process, and the process is compatible with traditional canned porridge production lines. The finished product has a mild and palatable
sweetness, with uniform cooking of all grains, a stable porridge
system, and good
room temperature storage performance. It solves the industry problems of existing similar products, such as excessive
sweetness, pungent
gastrodia elata
odor, inconsistent cooking of raw materials, and high cost of
mass production equipment. The entire process forms a complete and
collaborative processing system, suitable for large-scale industrial
continuous production.
