Problems solved by technology

According to reports, bitter melon peptide has anti-tumor, hypoglycemic, antibacterial and other effects. At present, the way to obtain bitter melon peptide is mainly to extract it from bitter melon fruit or bitter melon seeds. The yield is low, the cost is high, and it is not easy to produce on a large scale.

Embodiment 1

[0039]Degrease bitter gourd seeds by cold pressing to obtain defatted bitter gourd seed meal; record 100kg of bitter gourd seed meal as A, mix it with 1000L of water, adjust the pH value to 8.0-8.5, and extract at room temperature for 0.5h; after the extraction is completed, filter and filter the residue For the second extraction, pour the filtrate into an equal amount of bitter gourd seed meal, record it as B, adjust the pH value to 8.0-8.5, and extract at room temperature for 0.5h; ; After A completes the secondary extraction, discard the filter residue, pour the filtrate into an equal amount of bitter gourd seed meal, record it as C, adjust the pH value to 8.0-8.5 and extract at room temperature for 0.5h; after B completes the secondary extraction, discard the filter residue, The filtrate is poured into the filter residue of C to complete the first extraction for 0.5h, and the filtrate extracted by C for the first time is set aside; after the second extraction of sample C is...

Embodiment 2

[0041] Degrease bitter gourd seeds by cold pressing to obtain defatted bitter gourd seed meal; record 100kg of bitter gourd seed meal as A, mix it with 1500L of water, adjust the pH value to 9.5-10.0, and extract at room temperature for 1 hour; For the second extraction, the filtrate is poured into an equal amount of bitter gourd seed meal, recorded as B, and the pH is adjusted to 9.5-10.0, and extracted at room temperature for 1 hour; after B completes the first extraction, the filtrate is set aside, and the filter residue continues for the second extraction; A is completed After the secondary extraction, the filter residue was discarded, and the filtrate was poured into the same amount of bitter gourd seed meal, which was recorded as C, and the pH value was adjusted to 9.5-10.0, and extracted at room temperature for 1 hour; after the secondary extraction of B was completed, the filter residue was discarded, and the filtrate was poured into C Complete the extraction from the f...

Embodiment 3

[0043] Cold press and degrease the bitter gourd seeds to obtain defatted bitter gourd seed meal; record 100kg of bitter gourd seed meal as A, mix it with 500L of water, adjust the pH value to 8.0-8.5, and extract at room temperature for 1 hour; after the extraction is completed, filter and filter the residue for two For the second extraction, the filtrate was poured into an equal amount of bitter gourd seed meal, recorded as B, and the pH value was adjusted to 8.0-8.5 and extracted at room temperature for 1 hour; after the first extraction of B was completed, the filtrate was left for use, and the filter residue continued to be extracted for the second time; A After completing the second extraction, discard the filter residue, pour the filtrate into the same amount of bitter gourd seed meal, record as C, adjust the pH value to 8.0-8.5, and extract at room temperature for 1 hour; after B completes the secondary extraction, discard the filter residue, and pour the filtrate into C...

Abstract

The invention relates to the technical field of balsam pear seed peptides, particularly discloses bitter gourd seed peptide powder with a free radical scavenging effect and a preparation method and application thereof, and relates to high-purity and low-molecular-weight bitter gourd seed peptide powder and a preparation method and application thereof. The peptide content of the bitter gourd seed peptide powder is 90wt% or above, and the molecular weight of 80% or above of bitter gourd seed peptide is less than 500 Dalton. Degreased bitter gourd seed meal is subjected to protein extraction, enzymolysis, purification, concentration and drying to obtain the bitter gourd seed peptide. The method is simple and convenient to operate, high in yield, low in cost, stable in product quality, environment-friendly in process and suitable for large-scale production.

Description

technical field [0001] The invention relates to the technical field of balsam pear seed peptide, in particular to a balsam pear seed peptide powder with a free radical scavenging effect and a preparation method and application thereof. Background technique [0002] Bitter melon is a beneficial medicinal plant and vegetable with bitter fruit that is commonly used in cooking. In ancient my country, bitter gourd has been included in the category of traditional Chinese medicine. Bitter gourd has a bitter smell, is non-toxic, and is cold in nature. Bitter melon has good nutritional and medicinal value, and has significant efficacy in the clinical treatment of diabetes, inflammatory response and cancer. It has long been used as a functional food with the same source of medicine and food in China, Japan and other countries. Bitter melon seeds are very similar to bitter melon in terms of nutritional and medicinal value. Bitter melon seeds contain 21.8% ash, 19.5% fiber, 16.4% carb...
