Definitions
- the present invention is a method for storing unstable chlorophyll in the surrounding environment for a long time, and the stabilizer used is to stabilize chlorophyll using oils having a long unsaturated fatty structure represented by squalene.
- Chlorophyll which is widely used in the food industry as a natural color obtained from vegetables and fruits, has a form in which magnesium (Mg) ions are bonded to the center of the porphyrin ring and can be classified into types such as chlorophyll a, b, c, and d. have.
- Mg magnesium
- chlorophyll has a difference in content depending on the varieties, cultivated soil, and harvest time of the extracted plant, and is changed in heat, light, oxygen, acid, and enzyme, and thus has a disadvantage in terms of quality and customer satisfaction.
- Chlorophyll and chlorophyll derivatives show various physiological activities and are being studied in various fields such as wound healing, anti-inflammatory and anti-cancer treatment.
- chlorin e-6 plays an important role as a photosensitizer in photodynamic therapy
- copper chlorophylline sodium is also used for the purpose of removing body odor and removing inflammation.
- chlorophyll derivatives include the pheophytin and pyropheophytin series in which the central magnesium metal is substituted or removed, the chlorophyllide and the peoforbide series in which magnesium metal and phytol are removed, and chlorine produced through saponification reaction. It can be divided into series.
- the existing method for extracting chlorophyll from plants was to extract impurities with various organic solvents such as acetone, ethanol, hexane, and dioxane, and remove impurities through centrifugation and low temperature immersion.
- the method has a problem of using a solvent that cannot be applied to food and medicine.
- efforts have been made to apply ethanol to food, etc., but there is a problem in that an excessive amount of ethanol must be used in an impurity removal step or an extraction step.
- an organic solvent such as acetone must be used to remove polar impurities after extraction.
- extraction with supercritical fluids has advantages such as high solubility, fast mass transfer and heat transfer, low viscosity, high diffusion coefficient, and rapid permeability into micropores due to low surface tension. , Distillation, crystallization, absorption, adsorption, drying, cleaning, etc. It is an extraction method that can solve technical difficulties such as low efficiency, low quality, low speed, and adverse effects on the environment.
- Supercritical fluid extraction not only prevents or minimizes the occurrence of various pollutants (air, water, land) in the product production process, but also prevents harmfulness to human health and the environment by fundamentally preventing traditional product production technology. In preparation, it can bring economic benefits.
- Korean Patent Registration No. 1428486 discloses a method for producing chlorella extract using a supercritical fluid extraction method, but the extraction target and extraction method are different from the method for producing a chlorophyll-containing extract using the supercritical fluid extraction method of the present invention.
- chlorophyll has a very unstable characteristic to the surrounding environment, so its use range is limited and difficult to apply to the food business.
- dimetallation occurs with magnesium falling off
- high pH i.e. with basic, saponification reaction with phytol falls off.
- a decolorization reaction in which the porin ring is opened by an oxidation reaction occurs and its structure is destroyed.
- its structure is broken down and destroyed by various enzymes that break down chlorophyll present in the plant.
- the photoinduction between chlorophyll dissolved in the solution has the property of causing the structure to be excitedly destroyed in an unstable state by electron energy transfer. In particular, the higher the temperature, the faster the reaction rate.
