preparation example Construction

[0057] The preparation method of extract of the present invention generally comprises the following steps:

[0058] (1) Pretreatment: adjust the pH value of bamboo shoot processing waste liquid to 4-5, centrifuge to separate impurities, pre-concentrate to a certain volume, and go through coarse filtration and microfiltration before use.

[0059] (2) Ultrafiltration treatment: The feed liquid with a temperature between 40 and 50°C is passed through an ultrafiltration membrane system (such as an ultrafiltration membrane with a molecular weight cut-off of 5,000 to 100,000) at an operating pressure of 0.2 to 1Mpa, thereby achieving macromolecular filtration. Separation of substances from small and medium molecules such as amino acids, peptides, sugars, etc., to obtain ultrafiltration permeate.

[0060] (3) Reverse osmosis treatment: pass the above-mentioned ultrafiltration permeate through the reverse osmosis membrane system under the operating pressure of 1-2.5Mpa to achieve the ...

[0074] Preparation of Amino Acid Peptide Concentrate of Phyllostachys pubescens

[0075] The amino acid peptide extract of Phyllostachys pubescens (in the form of concentrate) was prepared according to the following steps.

[0076] Step 1) Preprocessing:

[0077] Collect the blanching waste water from the processing of moso bamboo shoots to the waste water tank, enter the pretreatment device through the waste liquid booster pump, adjust the pH value of the system to 4.2 with 0.1mol / L HCl solution, and centrifuge to remove the flocculent precipitate; After concentrating under reduced pressure to one-fifth of the volume, the particles and bacteria above 5 μm and 0.2 μm were removed by coarse filtration and microfiltration respectively, and the temperature of the feed liquid was kept at about 45°C.

[0078] Step 2) ultrafiltration treatment:

[0079] Pass the pretreated feed liquid through a closed roll-type ultrafiltration membrane system (polysulfone membrane with a molecular...

[0085] Preparation of Amino Acid Peptide Concentrate of Green Bamboo Shoots (Horseshoe Shoots)

[0086] According to the method similar to Example 1, green bamboo shoot amino acid peptide extract (in the form of concentrate) was prepared through the following steps.

[0087] Step 1) Preprocessing:

[0088] Collect green bamboo shoots (horseshoe shoots) processing and soaking waste liquid into the waste water tank, enter the pretreatment device through the waste liquid booster pump, adjust the pH value of the system to 4.5, and centrifuge to remove the flocculent precipitate; concentrate the clear liquid under reduced pressure to After about one-fifth of the volume, the particles and bacteria above 5 μm and 0.2 μm were removed by coarse filtration and microfiltration respectively, and the temperature of the feed liquid was kept at about 45°C.

[0089] Step 2) ultrafiltration treatment:

[0090] The pretreated feed liquid passes through the closed ultrafiltration membrane syst...

Abstract

A bamboo root amino-acid peptide extract, its production and use are disclosed. The extract contains amino acid 10-50wt%, which consists of free amino acid 5-40wt%, tyrosine, serine, aspartine, glutamic acid, alanine, phenylalaine, valine and delta-OH-Lys. It has good taste and can be used for functional food, beverage and condiment.

Description

technical field [0001] The invention relates to the field of agricultural and sideline product processing, and more specifically relates to an amino acid peptide composition separated from bamboo shoots or bamboo shoot processing waste liquid, as well as its preparation method and application. Background technique [0002] Bamboo is a perennial evergreen plant of the Gramineae subfamily Bambusoideae. There are more than 70 genera and more than 1,200 species in the world, and the bamboo forest area is about 22 million hectares. At present, about half of the world's population is involved in the production and consumption of bamboo products. The bamboo industry provides economic income, food and housing for 2.2 billion people in the world every year. The annual trade volume of global bamboo products has exceeded 8.5 billion US dollars. [0003] As the country with the richest bamboo resources in the world, my country has more than 40 genera and more than 500 kinds of bamboos, ...
