Problems solved by technology

[0007] The disadvantages and deficiencies of the above-mentioned prior art are that the pepsin and trypsin used are expensive and have many side reactions; bromelain has low efficiency and is not suitable for industrial production; although As1.398 neutral protease has moderate efficiency, it produces bitter peptides
Generally speaking, the selected enzyme preparation has low efficiency, long reaction time, low polypeptide yield, and low production efficiency; repeated use of acid and alkali to adjust the pH value of the material during the enzymolysis process is cumbersome, time-consuming, and difficult to control , there will inevitably be chemical residues in the product; there is no desalination and arsenic removal process in the production process, the actual product contains too much salt, the taste is too salty, and the arsenic content limit index is unstable due to changes in raw material production areas. These are harmful to the hygiene, safety and health of the product Both have adverse effects

Embodiment 1

[0022]Cut open the whole fresh sea cucumber along the abdomen, take out the intestines, wash away the sediment, rinse with drinking water and set aside. Take by weighing the sea cucumbers after washing according to the feeding amount of each pot of 150kg, grind them with a meat grinder, and the degree of grinding is controlled by an orifice plate with an aperture of Φ8mm. The shredded sea cucumbers are refined by ultrafine grinding, and the grinding fineness is below 10 μm. During the refining process, appropriate amount of water is added to keep the material in a good flow state. Pump the slurry into the enzymolysis tank, add drinking water to make the volume 300kg, and the concentration is about 9%. The slurry is heated up under stirring, and the temperature control value of the heater is accurately set according to experience to ensure that the final temperature is stable within the specified range. Add enzyme when the temperature rises to 45°C. The enzyme product is Pro...

Embodiment 2

[0024] Weigh 20kg of dry sea cucumber (whole sea cucumber or shredded sea cucumber), wash off surface attachments with clean water, and then soak in clean water, preferably hot water, for 1 to 5 hours. Process by the crushing and refining method described in Example 1. After the slurry is pumped into the enzymolysis tank, add drinking water to constant volume to 300kg, with a concentration of about 6%. Heat up according to the method described in Example 1, add the Protamex composite protease whose labeling activity is 1.5AU / g produced by Novozymes (China) Biotechnology Co., Ltd., Denmark, the amount of enzyme added is 0.4kg, and the pH of the material need not be adjusted when adding enzyme value, the velocity should be as uniform as possible. After adding the enzyme, pay attention to the changes in the material. The enzymatic hydrolysis is basically completed in about 2.5 hours, and then the filtration, desalination and arsenic removal can be carried out. Filtration, desal...

Embodiment 3

[0026] The sea cucumber peptide powder obtained in Example 1 or Example 2, without adding any other ingredients, is made into sea cucumber peptide capsule products with a capsule filling machine.

Abstract

The invention discloses a sea cucumber polypeptide functional food and a preparation method thereof which not only remarkably improves the content of polypeptide, but also has no chemical residues; the contents of salt and arsenic are low; the food is healthier and safer to eat; simultaneously the food is simply operated, easily controlled, is effective and saves energies. The key technical scheme includes: selecting a compound protease of Protamex and needing not to adjust the pH value of materials; carrying out processes of desalting and arsenic removing on an enzymolysis liquid; more than 80 percent of the molecular weight of the product is between 100 to 6000Dalt; wherein, the small polypeptide of 100 to 2100Dalt is more than 70 percent; the product components and the content weight percentages are as follows: 50 to 60 percent of polypeptide, 5 to 10 percent of free amino acids, 2.5 to 7.5 percent of mucoitin as well as containing the inherent nutrition components of a plurality of minerals and vitamins of the sea cucumber. The product has the effects of resisting knub, reducing blood pressure, preventing cardio-cerebrovascular diseases, resisting fatigue, delaying senescence, improving the immunity. The food can be used as a healthy food to eat and can also be used as a food and a medicine additive.

Description

technical field [0001] The invention relates to a functional food processed by marine organisms using protein enzymatic hydrolysis technology, in particular to a sea cucumber peptide functional food processed by enzymatic protein hydrolysis of sea cucumbers. The invention also relates to a process for the preparation of the product. Background technique [0002] Sea cucumber has been a valuable product for nourishing and strengthening the body and a good medicine for preventing and curing some diseases recorded in the medical books of the past dynasties in my country since ancient times. According to the "Food Materia Medica" of the Ming Dynasty, sea cucumbers have the functions of nourishing vitality, nourishing internal organs and dispelling deficiency. Qing Dynasty "Compendium of Materia Medica Supplements" and other Chinese medicine classics record: sea cucumber, warm in nature, sweet and salty in taste, enters the heart and kidney channels. It has many functions such ...
