Problems solved by technology

However, for the extraction and separation of wolfberry polysaccharides, the mainstream production process of most enterprises still uses the traditional hot water cooking method, which has disadvantages such as long extraction time, high energy consumption, and low extraction efficiency.
Since the advent of subcritical water extraction technology, it has become a hot spot in the field of separation and extraction due to its advantages of short extraction time, high efficiency, continuous extraction, cheap and easy to obtain, and environmental friendliness. However, subcritical water extraction technology requires a higher temperature , may cause irreversible changes in the properties of heat-sensitive substances or the structure of macromolecular substances, which limits its wide application

Embodiment 1

[0016] A kind of processing method of donkey-hide gelatin ginger tea is characterized in that it is made up of following steps:

[0017] 1) Take fresh ginger, wash and slice, dry at 55°C far-infrared, crush through a 60-mesh sieve, add 20 times the amount of 70% ethanol solution, reflux extraction in a 65°C water bath for 1.5 hours, centrifuge to take the supernatant, and recover ethanol Solvent, concentrated and dried to obtain the extract;

[0018] 2) Crush wolfberry to 60 mesh, add subcritical water at a material-to-liquid ratio of 1:30 (mL / g), conduct ultrasonic-assisted extraction at 5MPa, 150W, and 90°C for 50 minutes, and filter to obtain the extract;

[0019] 3) Wash the fresh porcine pancreas, remove a large amount of fat, and homogenate to obtain a homogenate of porcine pancreas, add 1.3% sodium chloride, 1.2% glycerin, and 1.2% trypsin powder, and then add 2 times the volume fraction of 30% ethanol solution, adjust the pH to 4.5 with citric acid, rotate and extract...

Abstract

The invention discloses a processing method of donkey-hide gelatin and ginger tea. The processing method is characterized in that crude trypsin is extracted by processing pig pancreas, so that the activity is better and the benefit for reducing the production cost is achieved; the donkey-hide gelatin is hydrolyzed by the crude trypsin to obtain small-molecular peptides with certain physiological activity, so that the digestion and the absorption by a human body are easier and the effects are exerted more easily; and continuous extraction of effective components of fresh ginger is realized by asubcritical water extraction mode, and the cavitation effect of ultrasonic wave is utilized to generate an enhancing action for extracting subcritical water.

Description

technical field [0001] The invention relates to the field of ginger tea processing, and mainly relates to a processing method of donkey-hide gelatin ginger tea. Background technique [0002] Plant polyphenols are a large class of complex polyphenolic compounds widely present in plants, which have strong functions of donating hydrogen and removing harmful free radicals in the body. Ginger is an important spice seasoning all over the world, and it is also a traditional medicinal and edible plant in Asia. Its main active ingredients are volatile essential oils, gingerol and flavonoids, among which gingerol and flavonoids belong to polyphenolic compounds, which are the most important antioxidant and other functional factors in ginger. They are widely used in food, medicine, cosmetics and health care. Products and other industries have a wide range of applications. Therefore, the development of ginger polyphenols has great research value and application prospects. Solvent refl...
