Embodiment 1

[0021] 1) Pre-treatment: peel the durian, remove the seeds, and extract the durian pulp.

[0022] 2) Extraction: Put the durian pulp in 8 times the amount of deionized water and extract twice at 60°C, stir occasionally during the extraction process, heat to boil and keep the temperature for 2 hours, collect the first extraction material liquid, and extract again for the second time Add 5 times the amount of deionized water, heat and boil for 2 hours, and collect the second extraction material liquid.

[0023] 3) Filtration: the extract is centrifugally filtered by a centrifuge.

[0024] 4) Concentration: The filtered extract is introduced into a concentrator for concentration under reduced pressure. The temperature is controlled below 60 degrees Celsius, the vacuum degree is controlled above 0.06 MPa, and the concentration is about 25-30 Baume degrees to obtain a paste-like durian extract. thing.

Abstract

The invention discloses paste or pulverescent Durio zibethinus extract and its preparation method. The Durio zibethinus extract is prepared by extracting Durio zibethinus flesh with water or lower alcohol such as methanol, ethanol, propanol, isopropanol or butanol; filtering; concentrating to give paste; or further spray-drying to give powder. The obtained paste is yellowish with Baume degree of 25-30 and has special flavor; and the powder is yellow brown, has special flavor, and contains the Durio zibethinus extract more than 80 wt% and protein more than 9.5 wt%. It can be used for preparinghealth food and food, especially fruit juice and baked food.

Description

technical field [0001] The invention relates to a durian extract and a preparation method thereof, and also relates to the application of the durian extract in the field of health food and food, especially in fruit juice and baked food. Background technique [0002] Durian is the fruit of the evergreen tree durian (Durio zibethinus L.) of Kapokaceae, which is produced in tropical regions. The leaves are dense, elliptical, with a sharp tip; cyme, flower color is light yellow; the fruit is elliptical on the trunk and branches, the peel is firm, densely grown triangular hard thorns, yellow or yellow-green, each fruit weighs 1.2 --3 kg. Durian is a well-known high-quality fruit. The mature pulp is light yellow, sticky and juicy, soft and sweet, and tastes like old cheese and onion. Durian has a strong and special smell, and it smells extremely stinky, but it tastes delicious, mellow, delicious, sweet like honey, and smooth like grease. [0003] Durian is rich in protein and l...
