The invention relates to the technical field of
food processing, in particular to a four-season
grapefruit juice production process based on a quality key
control point, which comprises the steps of raw and auxiliary material acceptance check,
raw material pretreatment, proportioning,
deep processing, automatic filling and capping, sterilization, code printing and labeling, finished product warehousing and the like.
Pesticide residue and heavy
metal detection is carried out on four-season grapefruit raw materials, technologies such as three-stage countercurrent cleaning,
laser-guided peeling, high-precision automatic batching, two-stage homogenization and ultrahigh-temperature instantaneous sterilization are adopted, and full-process digital monitoring and tracing are achieved in combination with an online
monitoring system. According to the process, all links of production are accurately controlled, more than 95% of nutritional ingredients of the pulp are effectively reserved, the
retention rate of nutrients such as
vitamin C and
naringin is more than 85%, the
total bacterial count of a finished product is smaller than or equal to 10 CFU / mL, and the layering rate in the
shelf life is lower than 5%. According to the invention, the product quality, the production efficiency and the safety are obviously improved, the
traceability of the production process is realized, and an efficient and high-quality solution is provided for the production of the four-season
grapefruit juice.
