Method for on-site collection and fresh preservation of sheep placenta and amniotic fluid

Abstract

A sheep placenta not only has rich nutritional value, but also has a cell immune function, a cell repairing function and the like, but active ingredients in the sheep placenta have significant change after the sheep placenta is separated from a maternal body and show a significantly decreasing tendency. The invention discloses a method for on-site collection and fresh preservation of the sheep placenta and an amniotic fluid. The method comprises the steps: preparing double interlayer collection bags each having an outer layer which is a cold medium; respectively filling the amniotic fluid and the sheep placenta into the collection bags for vacuum package; putting into an instant freezer for ultrarapid freezing, and carrying out low-temperature frozen storage; and thawing the frozen-storage amniotic fluid and the frozen-storage sheep placenta by running water or microwaves for follow-up development. The method prevents the change of the active ingredients of the amniotic fluid and the sheep placenta during the collection process, maximizes to maintain nutrient substances and the active ingredients of the amniotic fluid and the sheep placenta, and provides a basic guarantee for deep processing of the amniotic fluid and the sheep placenta. The method has short quick-freezing time, simple process and convenient operation, and is a new technology for retaining the maximum bioactive ingredients of the amniotic fluid and the sheep placenta.

Description

technical field [0001] The invention relates to a fresh-keeping method for food raw materials, in particular to a method for on-site collection and fresh-keeping of sheep placenta and amniotic fluid, which belongs to the technical field of food processing. Background technique [0002] Sheep placenta has important bioactive functions and is rich in all the original life substances necessary for the conception of life. It is rich in protein, 17 kinds of amino acids, 14 kinds of trace elements, phospholipids, lipopolysaccharides, vitamins, and a variety of active polypeptides related to immune function and normal operation of the body. The proportion of natural nutrients is closest to the needs of the human body . A number of studies have shown that sheep placenta has obvious immune regulation effects. Modern pharmacological studies and clinical applications have shown that it has anti-infection, regulation of humoral immunity, lactation, promotion of fetal development, trea...

Problems solved by technology

The reproductive time cycle of sheep is relatively concentrated, about one month or even a few weeks, so it is convenient to collect sheep placenta, but because sheep placenta contains 85% water, and the solid matter also contains about 85% protein, experiments have proved Fresh sheep placenta will spoil and deteriorate when stored at 0-4°C for 2-4 days, so it is very difficult to keep fresh, so it is often treated as waste, which not only causes a waste of resources but also pollutes the environment, which is not conducive to the sustainable development of agriculture and animal husbandry. sustainable development

At present, there are a few enterprises in China that process sheep placenta, but improper collection and storage methods cause the loss of active ingredients in sheep placenta, which significantly reduces the value of deep processing and utilization. Therefore, it is very necessary to effectively preserve the freshness of sheep placenta and active ingredients in amniotic fluid
