Artichoke leaves extract preparation technology and detection method thereof

Abstract

The present application discloses a preparation process and detection method of artichoke extract. The preparation process includes the following steps: adding artichoke into the reaction kettle, and then adding water; heating until the temperature in the reaction kettle is 60° C. Make the condensed water circulate, when the temperature rises to 90‑95°C, turn on the heat reflux; repeat step 2 twice; filter the substance obtained in step 3 through the first filter membrane to obtain the extract; concentrate the concentration of the extract to 1:1‑1 : 2mL / g or relative density to 1.08-1.15, use ethanol solution alcohol precipitation of different concentrations respectively, obtain supernatant, supernatant is filtered through the second filter membrane, obtain filtrate; Filtrate is adsorbed by resin column; Washing with water and alcohol, filtering the alcohol washing solution through a microporous filter to remove impurities, then concentrating in a vacuum to obtain a thick slurry, spray drying, and sieving to obtain the artichoke extract. In the embodiment of the present application, the extraction efficiency of the artichoke extract is effectively improved through the process steps of extraction, alcohol precipitation, filtration and drying of the artichoke.

Description

technical field [0001] This application relates to the technical field of biological extraction, in particular to a preparation process and detection method of artichoke extract. Background technique [0002] Artichoke, also known as artichoke, food tray artichoke, artichoke, French artichoke, ball artichoke, is a plant of the genus Artichoke that grows along the Mediterranean coast. Hong Kong generally translates it as Yazhi bamboo or Asian Branches of bamboo. Its flower buds can be used for cooking, and it was first introduced to Chinese society through Italian cuisine. It is now distributed in Shanghai, Zhejiang, Hunan, Beijing, Yunnan, Shaanxi Province, Shandong Province and other places in mainland China. Artichoke tastes between fresh bamboo shoots and mushrooms when eaten. It has the effect of quenching thirst and relieving alcohol. It is rich in nutrition, healthy and beautiful, and has a high edible value. It has the reputation of "the king of vegetables". [000...
