Embodiment 1

[0032] Embodiment 1, a kind of preparation method of mulberry leaf nutrient protein instant powder, carries out following steps successively:

[0033] 1) Select complete and pest-free mulberry leaves picked in Jinhua, Zhejiang Province in October, wash them with running water, dry them naturally in the shade to constant weight (moisture content ≤ 5%), and crush them through a 60-mesh sieve to obtain mulberry leaf powder.

[0034] 2) Take 100g of mulberry leaf powder, add 3000mL of NaCl aqueous solution with a mass fraction of 0.4%, ultrasonically treat at 200W for 20min, then place it at room temperature of 20-25°C for 30min (i.e. leaching for 30min); centrifuge at 3000rpm for 15min.

[0035] Take the supernatant obtained by centrifugation and adjust the pH to 4 with a concentration of 0.5mol / L HCl solution to achieve acid precipitation, centrifuge at 3000rpm for 15min, and freeze-dry the obtained precipitate (dry at -70°C for 10h) to obtain mulberry leaf protein powder (about ...

Embodiment 2

[0044] Embodiment 2 A kind of manufacturing process of mulberry leaf nutritional protein instant powder, the steps are as follows:

[0045] 1) Choose complete and pest-free mulberry leaves picked in early November in Jinhua, Zhejiang, wash them with running water, dry them naturally, and crush them with a grinder until they can pass through a 60-mesh sieve to obtain mulberry leaf powder (moisture content ≤ 5%).

[0046] 2) Take 100g of mulberry leaf powder, add 1500mL of 0.2% NaCl aqueous solution, 400W ultrasonic treatment for 10min, then put in a water bath (leaching) at 40-45℃ for 20min, and then centrifuge at 3000rpm for 15min.

[0047] The supernatant obtained by centrifugation was adjusted to pH 3 with 0.5mol / L% HCl solution to achieve acid precipitation, centrifuged at 3000rpm for 15min, and the precipitate was freeze-dried (dried at -70°C for 10h) to obtain mulberry leaf protein powder (about 20.7 g). The moisture content of this mulberry leaf protein powder is ≤5%. ...

Abstract

The invention discloses a preparation method of folium mori nutritious protein instant powder. The preparation method comprises the following steps of 1) cleaning folium mori through running water, naturally drying in the shade, and crushing; 2) adding a 0.2 to 1.0% by mass NaCl aqueous solution to folium mori powder, ultrasonically processing at 200 to 500W for 10 to 40 minutes, digesting at 20 to 45 DEG C for 10 to 50 minutes, centrifuging, collecting centrifuged supernate, adjusting pH (Potential of Hydrogen) to 1 to 4.5 to realize acid precipitation, centrifuging, freezing and drying the obtained precipitate to obtain folium mori protein powder; 3) adding beta-cyclodextrin and neutral protein powder to the folium mori protein powder, adding water to dissolve; heating at 35 to 50 DEG C for 10 to 50 minutes, and filtering or centrifuging to obtain a folium mori nutritious protein powder solution; and 4) performing rotary distillation, concentrating and spray drying on the folium mori nutritious protein powder solution to obtain the folium mori nutritious protein instant powder.

Description

technical field [0001] The invention relates to a preparation method of mulberry leaf nutritional protein instant powder. Background technique [0002] In my country, mulberry leaves are abundant in resources, but the utilization of mulberry leaves is very limited except that they are used for raising silkworms in the sericulture industry. Therefore, it is of great significance to develop new uses of mulberry leaves, improve the traditional mulberry leaf utilization structure, develop the comprehensive utilization potential of mulberry leaves, and improve economic and social benefits. [0003] According to research, the protein content of mulberry leaves is more than 20%, which is a higher content of plant leaf proteins. Its amino acid composition is generally consistent with that of defatted soybean flour. Pork, chicken and silver carp, etc., are beneficial to the body's absorption and utilization. Glutamic acid with the highest content in mulberry leaves plays an importa...
