Embodiment 1

[0017] (1) Weigh a certain amount of lotus root dregs, mix with appropriate amount of water, adjust the pH to 6.0, and heat to 30°C;

[0018] (2) Add α-amylase at a ratio of 800 U / g to lotus root dregs, react for 1 hour to inactivate the enzyme, and then add papain at a ratio of 20 U / g to lotus root dregs , acting for 0.5 hours;

[0019] (3) Centrifuge the above reaction mixture at 3000 rpm for 10 minutes, then remove the supernatant, and obtain the lotus root fiber after the obtained precipitate is fully washed and centrifuged;

[0020] (4) The obtained lotus root fiber was subjected to processes such as microwave drying (20 minutes), extruding and puffing, ultrafine pulverization, etc., to finally obtain activated lotus root fiber powder.

Embodiment 2

[0022] (1) Weigh a certain amount of lotus root dregs, mix with appropriate amount of water, adjust the pH to 6.0, and heat to 50°C;

[0023] (2) Add α-amylase at a ratio of 100 U / g to lotus root dregs, react for 2 hours, then inactivate the enzyme, and then add papain at a ratio of 10 U / g to lotus root dregs , act for 1 hour;

[0024] (3) centrifuging the above reaction mixture at a speed of 6000 rpm for 10 minutes and then removing the supernatant, and the resulting precipitate is fully washed and centrifuged to obtain the lotus root fiber;

[0025] (4) The obtained lotus root fiber was subjected to processes such as microwave drying (20 minutes), extruding and puffing, ultrafine pulverization, etc., to finally obtain activated lotus root fiber powder.

Embodiment 3

[0027] (1) Weigh a certain amount of lotus root dregs, mix with appropriate amount of water, adjust the pH to 6.0, and heat to 60°C;

Abstract

The invention provides a preparation method of activated lotus root fiber powder, pertaining to the field of biochemical food, which relates to a method used for extracting lotus root fiber by enzyme. After the lotus root starch is extracted, lotus root residue is taken as material, added with water, and heated to the temperature between 30 to 70 DEG C; Alpha-amylase and proteinase are respectively adopted to hydrolyze the starch and protein in the mixing liquid, then the mixing liquid is filtered, and the obtained condensate is dried by microwave, extruded, puffed, ultramicro crushed in sequence, and finally the activated lotus root fiber powder is prepared. The invention overcomes the shortcomings of the traditional chemical method, and has the advantages of single enzyme catalysis reaction, little byproduct, high product purity, moderate reaction conditions, environment friendliness, simple and easy controlled reaction process and easy separating products.

Description

technical field [0001] The invention belongs to the fields of biochemistry and food, and relates to a method for extracting lotus root fiber by using enzymes. Background technique [0002] Lotus root (Nelumbo uucifra gaertn), also known as lotus root, lotus root, hibiscus, etc., is a perennial aquatic herbaceous rhizome plant of the Nymphaeaceae Lily family, mainly edible with fat and tender rhizomes. Lotus root rhizome is rich in starch and dietary fiber. Lotus root is an important aquatic vegetable in my country. It has a long history of cultivation and is mostly cultivated in Jiangsu, Zhejiang, Hubei and other places in my country. [0003] In addition to fresh food, lotus root is traditionally mainly used to extract lotus root starch, and the resulting lotus root dregs are used as feed or fertilizer. The development of lotus root production and processing industry has greatly promoted the development of regional economy, and the lotus root industry has become an effect...
