The invention belongs to the technical field of
food processing, and discloses a preparation process of
bamboo salt, green plum and
loquat leaf extract. Based on 100 kg of loquat fruits, the process comprises the following steps: taking loquat pulp, performing vacuum concentration, removing kernels of green plums, performing pulping pretreatment, mixing and boiling main materials, adding
bamboo salt in sections, collecting paste, sterilizing and storing. Wherein the temperature of the main material is 100 DEG C 3 hours before boiling, the temperature of the main material is 85 DEG C 4 hours before boiling, and the
bamboo salt is equivalently added twice from the 5th hour; through the process, the mineral
retention rate of the bamboo salt exceeds 95%, the
flavor synergy is improved, the pH value of the finished product is stabilized at 4.2-4.8, the finished product has the effects of moistening
lung to arrest cough, promoting salivation and relaxing bowels, and the
shelf life reaches 18 months. According to the preparation method disclosed by the invention, the core defects of activity loss and
flavor imbalance of functional auxiliary materials in the prior art are overcome by virtue of a systematic preparation process flow for reconstructing the
loquat leaf extract and particularly by innovatively introducing a bamboo salt sectional adding mechanism and a
temperature gradient control strategy; and breakthrough improvement is realized in a plurality of dimensions such as sensory quality, nutritional functions, product stability and process
controllability.
