Problems solved by technology

In fact, the antioxidant activity of papaya extract is also one of the important reasons why it is suitable for use as medicine, cosmetics and food additives, but there is no research on the antioxidant activity of papaya extract, and the secondary metabolites of papaya There are no reports on the development and utilization of its antioxidant activity
[0004] In addition, the current panic among people caused by the toxicity of food additives such as melamine and Sudan Red has been making people turn pale on food additives, and the safe storage and preservation of processed products is also the focus of attention. Therefore, it is very important to develop non-toxic antioxidant additives. necessary

Embodiment 1

[0024] The papaya seed extract provided in this example is prepared by the following method: after soaking the papaya seeds in ethanol with a volume concentration of 90% at room temperature for extraction, the filtrate is rotary evaporated until the ethanol is evaporated to dryness to obtain papaya seeds The crude extract is dissolved in water, extracted with organic solvents petroleum ether, ethyl acetate and n-butanol, and then concentrated to obtain the papaya seed extract.

Embodiment 2

[0026] For the papaya seed extract provided in this example, the papaya seeds are washed with tap water; the washed seeds are dried in the sun until they are 80% dry, and pulverized with a pulverizer; the extract is extracted with ethanol with a volume concentration of 30% at room temperature , the first leaching for 20 days, the second and third leaching in ethanol for 10 days each, after each leaching, filter the leaching solution with a filter cloth in time for recovery, and return the filter residue to the leaching container , the recovered filtrates were combined and stored in a sealed container, and concentrated by rotary evaporation at a constant temperature of 55°C until the ethanol solvent was completely evaporated to dryness, and the crude ethanol extract was accumulated in the rotary evaporator; the total crude extract was used Soluble in water, extract with petroleum ether, ethyl acetate and n-butanol successively, extract continuously for 5 times, and concentrate t...

Embodiment 3

[0028] For the papaya seed extract provided in this example, the papaya seeds are washed with tap water; the washed seeds are dried in the sun until they are 80% dry, and then pulverized with a pulverizer; extracted by ethanol with a volume concentration of 50% at room temperature , the first leaching for 2 weeks, the second and third leaching in ethanol for 1 week each, after each leaching, filter the leaching solution with filter cloth in time for recovery, and return the filter residue to the leaching container In the process, the recovered filtrates were combined and stored in a sealed container; the ethanol extract was concentrated by rotary evaporation at 55°C until the ethanol solvent was completely evaporated to dryness, and the crude ethanol extract was accumulated in the rotary evaporator; the total crude extract The product was dissolved in water, extracted with n-butanol, and extracted continuously for 3 times respectively, and the extract was concentrated by rotary...

Abstract

The invention discloses an extract of carica papaya L. seeds, which is prepared by the following steps: dissolving the carica papaya L. seeds into ethanol and lixiviating the carica papaya L. seeds at the room temperature, rotationally steaming the filtered solution till the ethanol is evaporated to obtain a coarse extract of the carica papaya L. seeds, dissolving the coarse extract into water, then extracting the coarse extract by using an organic solvent, and concentrating the extract to obtain the extract of the carica papaya L. seeds. The invention also discloses a preparation method for the extract and application thereof. The extract is pure natural, has no toxic or side effect, has stability to illumination and metal ions (calcium, iron and zinc), and is suitable for acid conditions; the anti-oxidation activity of the extract is enhanced along with the rise of the temperature at the temperature of below 100 DEG C; the production method has the advantages of readily available raw materials, high waste utilization rate and low cost; and the prepared product can be widely used in the field of food, medicament, cosmetics, veterinary medicament, feed and the like.

Description

technical field [0001] The invention relates to a papaya seed extract, a preparation method of the extract and its use as an antioxidant additive for food, medicine, cosmetics, feed or veterinary medicine, and belongs to the technical field of comprehensive development and utilization of plant natural products. Background technique [0002] Papaya (Carica Papaya L.) is a tropical evergreen fruit tree native to Mexico and Central America. In my country, it is mainly distributed in Guangdong, Hainan, Guangxi, Yunnan, Taiwan, Fujian and other provinces and regions. It is also found in Xichang, Sichuan and Ganzhou, Jiangxi. A small amount of distribution, among them, Hainan is the most suitable area for papaya cultivation in my country. After the papaya fruit is used for consumption, a large amount of seeds, peels and plant residues are often discarded, causing environmental pollution for human settlements. It is a waste resource that can be developed and utilized. In order to m...
