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...

Examples

Embodiment 1

[0016] a. Select healthy pregnant ewes, prepare a double-layered collection bag and sterilize it for later use. The outer layer of the double-layered collection bag is a mixture of ice and water at a temperature of 0°C;

[0017] b. When the lamb is born, put the amniotic fluid into the sterilized collection bag in time and vacuum pack it immediately;

[0018] c. Immediately put the vacuum-packed amniotic fluid into the quick freezer for ultra-fast freezing, the temperature of the refrigerant is -60°C, and the freezing time is 6 minutes;

[0019] d. Freeze the quick-frozen amniotic fluid at -20°C;

[0020] e. After the lamb is born, when the sheep placenta is separated from the mother, the umbilical cord is cut, and the sheep placenta is immediately put into a sterilized collection bag and immediately vacuum-packed;

[0021] f. Immediately put the vacuum-packed sheep placenta into the quick-freezing machine for ultra-fast freezing, the temperature of th...

[0025] a. Select healthy pregnant ewes, prepare double-layered collection bags and sterilize them for later use. The outer layer of double-layered collection bags is ethanol with a temperature of -20~-10°C;

[0026] b. When the lamb is born, put the amniotic fluid into the sterilized collection bag in time and vacuum pack it immediately;

[0027] c. Immediately put the vacuum-packed amniotic fluid into the quick freezer for ultra-fast freezing, the temperature of the refrigerant is -50°C, and the freezing time is 8 minutes;

[0028] d. Freeze the quick-frozen amniotic fluid at -10°C;

[0029] e. After the lamb is born, when the sheep placenta is separated from the mother, the umbilical cord is cut, and the sheep placenta is immediately put into a sterilized collection bag and immediately vacuum-packed;

[0030] f. Immediately put the vacuum-packed sheep placenta into the quick-freezing machine for ultra-fast freezing, the temperature of the refrigerant...
