Problems solved by technology

2. Sea cucumber saponin is a substance that is sensitive to various enzymes, acids, and alkalis, and can break glycoside bonds. In addition, saponin hydrolase is not separated from saponin, and internal and external factors work together, and the activity of saponin is almost completely lost.

Embodiment 1

[0027] Embodiment one: get 100 liters of water of sea cucumbers boiled in the sea cucumber factory, filter or purify, and measure its solid content to be 2.5 grams per liter, and get 100 liters of 90% (v / v) edible alcohol in addition for subsequent use. Boil sea cucumber water, let it dry, measure its temperature as 30°C, and the alcohol temperature as 20°C. Slowly pour the sea cucumber water infusion into the edible alcohol, stir while pouring, after complete miscibility, let it stand for 48 hours, centrifuge to obtain sediment, dry and pulverize to obtain 235 grams of sea cucumber powder. The protein content is 45%, the total amino acid content is 38.5%, and the water content is less than 8%.

Embodiment 2

[0028] Example 2: The sea cucumber extraction method is prepared by using the sea cucumber water infusion drying method.

[0029] a. The sea cucumber water infusion with a solid weight content of more than 0.01 g / liter is used;

[0030] b. The drying methods include natural drying, heating drying, freeze drying, reduced pressure drying, freeze drying under reduced pressure, and spray drying.

[0031] When the heat drying method is adopted, the sea cucumber water immersion liquid can be heated and kept above 70°C to a slightly boiling state, and suspended matter continuously appears. Take it out with a stove, and then fry it dry in a water bath or a gas cooker.

Embodiment 3

[0032] Embodiment 3: Take 100 liters of sea cucumber water infusion, use ultrafiltration to concentrate and filter the sea cucumber water infusion or carry out graded interception, measure its solid matter weight content as 3.2 grams per liter, put it in a pot and heat it, and keep it in a slightly boiling state , with the concentration of the volume of the water immersion liquid, there are suspended solids appearing continuously, and they are fished out with a stove, and then fried in a flat-bottomed gas pan, and then dried in an oven until the water content is less than 8%, crushed, sieved, and passed through The measured protein content is 38%, the total amount of amino acid is 32%, and finally 250g of powder is obtained.

Abstract

The invention relates to a sea cucumber extract and a preparation method thereof. The sea cucumber extract prepared from sea cucumber infusion as a raw material by precipitation method or drying method has no connective tissues under microscopic examination; has the content of lipids or lipoproteins less than 5% and the content of free amino acids less than 10%; and contains proteins, peptides, glycoproteins, saponins and other trace substances in balancing amount. Before the precipitation or drying process, the sea cucumber infusion can be concentrated and filtered or entrapped according to classification by using ultrafiltration. The inventive method prepares the sea cucumber extract from the waste sea cucumber infusion by precipitation method with ethanol, Chinese liquor or acetone or drying method. The sea cucumber extract has high contents of saponins and low contents of arsenicum (As), mercury (Hg) and chromium (Cr), and the contained proteins and peptides are small molecular weight water-soluble substances which are very suitable for being absorbed by human body.

Description

[technical field] [0001] The invention relates to a sea cucumber extract, in particular to a sea cucumber extract prepared from sea cucumber water infusion liquid. [0002] The invention also relates to a method for preparing sea cucumber extract by using sea cucumber water infusion as raw material. [Background technique] [0003] Because sea cucumber is a nourishing product that has been verified for thousands of years, sea cucumber and its products have been heated up in recent years. The thorny sea cucumber (stichopus japonicus selenka), which is abundant in the Bohai Sea and the Yellow Sea, is known as the king of sea cucumbers and has been a royal tribute since ancient times. Current research has confirmed that it is the most abundant in nutritional active substances. According to incomplete statistics, there are more than ten companies in the country that use sea cucumbers to make capsules. The main methods used are drying method and enzymatic hydrolysis method.
