Detailed Description
As shown in fig. 1, the invention relates to a processing method of chilled goat milk, which comprises the following steps:
firstly, primarily selecting goat milk;
fresh goat milk on the same day of milking is collected according to standardization, namely the fresh goat milk with the chemical index, the physical and chemical index and the microorganism index meeting the standard is used as a raw material; fresh goat milk collected on that day was taken as a batch.
Step two, optimizing raw materials;
the raw milk is filtered, purified and standardized to improve the quality and stability;
step three, bagging and sealing;
respectively filling the optimized raw milk into sterile plastic bags with the volume of 20-50 liters, and respectively sealing;
step four, cooling and storing;
and (3) quickly placing the sealed raw milk bag into a freezing chamber or a freezing cabinet at the temperature of 18 ℃ below zero, and cooling and storing.
And further, after the raw milk sealed in the fourth step reaches a certain yield, namely when the accumulated frozen milk amount reaches 500-1000 kg, blending the raw milk, and unfreezing. The raw milk bag after unfreezing and sealing is immersed in long running water at the temperature of 0-28 ℃ for unfreezing, and the standing time is 2-5 hours (h).
Further, screening the goat milk again; and (4) testing whether the thawing milk sensibility index, the physicochemical index and the microorganism index are the same as the original milk index in the step one in batches, and testing whether one index meets the standard or not by taking the fresh goat milk collected on the same day as one batch. The screening aims to ensure that the nutrient contents and the like of the fresh goat milk are not lost.
Further, the raw milk meeting the standard is broken and bagged in an automatic liquid packaging machine, the automatic liquid packaging machine adopts a Huili machine with the brand name, the sterilization function is carried out before the raw milk is filled, the raw milk is sterilized by ultraviolet rays, and meanwhile, the high-temperature steamed and cooked bags are also filled in the automatic liquid packaging machine as sub-bags to be sterilized by ultraviolet rays, so that the preparation for sub-bag packaging and sealing is carried out. The volume of the bag is 100ml to 1000 ml. And filling and sealing the bags under an aseptic condition when the bags are packaged separately.
Further, pasteurizing the packaged goat milk with bags by adopting a low-temperature sterilization method or a high-temperature sterilization method, namely, a low-temperature sterilization method is 65-70 ℃, and the sterilization time is 25-35 min; or a high-temperature sterilization method is adopted for 75-80 ℃, and the sterilization time is 15-20 s.
Further, after pasteurization, quickly immersing the mixture into long flowing water at the temperature of between 0 and 28 ℃ to reduce the temperature to be below 20 ℃, and then placing the mixture into a quick freezing chamber, wherein the quick freezing temperature is minus 36 ℃ and the quick freezing time is 2 to 4 hours.
Further, the frozen goat milk is transferred to a-18 ℃ freezer (/ cabinet) to be stored, transported, distributed and sold in frozen block form. Generally, when the frozen square block capacity of the frozen fresh goat milk is 100 ml-1000 ml, the frozen fresh goat milk is sold and distributed.
After receiving the frozen fresh goat milk, the consumer can drink the frozen fresh goat milk by heating the goat milk in a pot with a bag or heating the goat milk in a container after unpacking the goat milk and placing the goat milk in the container by microwave heating, and the frozen fresh goat milk is stronger in taste and better in mouthfeel.
