Embodiment 1

[0036] Determination of sugar content

[0037] Determination of reducing sugars (including glucose, fructose, maltose)

[0038] GB / T 5009.7-2003

[0039] 1. Measuring principle:

[0040] After removing the protein from the sample, directly titrate the calibrated Fehling's solution under heating conditions. After the Fehling's solution is reduced to precipitate cuprous oxide, the excess reducing sugar will immediately reduce the methylene blue and make the blue color fade. . Calculate the amount of reducing sugar based on the consumed volume of the sample.

[0041] 2. Reagents

[0042] Unless otherwise specified, the experimental water was distilled water, and the reagents were of analytical grade.

[0043] (1) Ferrin A solution: Weigh 15g of copper sulfate (CuSO4·5H2O), and 0.05g of methylene blue, dissolve in water and dilute to 1L.

[0044] (2) Feilin B solution: Weigh 50g potassium sodium tartrate and 75g sodium hydroxide, dissolve in water, then add 4g potas...

[0087] Processing of mulberry freeze-dried powder

[0088] The mulberries used in this embodiment, whose ripening period coincides with continuous rainy days, are washed with clear water after bubbling, then sprayed, air-dried at room temperature, and then entered into a beater to make a pulp, and continue to stir for 5 minutes. Detect the obtained fruit pulp, its water content is 90%, and the sugar content is 7%. Put the pulp into a quick-freezing tray, control the thickness of the pulp to 4 cm, and freeze it to -20°C to make it completely solidified. Take out the quick-frozen plate, thaw at room temperature (30°C), filter off the leached water, and check that the moisture content of the remaining pulp is 80%, which is in line with S0 / (6S 0 +19T 0 ) formula requirements, dehydration and desugaring are completed. It is air-dried at a low temperature of -20°C until the water content is 5%, and crushed by ultrasonic waves, so that the particle size is less than 10 microns, a...

Embodiment 3

[0090] Processing of control group mulberry freeze-dried powder

[0091] After the mulberry fruit is picked, it is rinsed by bubbling with clean water, then sprayed, air-dried at room temperature, and then put into a beater to make a pulp, and continue to stir for 5 minutes. Without testing, it is air-dried at -20°C to a moisture content of 5%, and crushed by ultrasonic waves until the particle size is less than 10 microns, then the processing is complete.

Abstract

A freeze-dried mulberry fruit powder is prepared from mulberry fruit through washing, beating, stirring, removing saccharide and water by freezing-thawing method or centrifugal method, freeze drying and superfine pulverizing.

Description

technical field [0001] The invention belongs to the field of food processing, in particular to a processing method of simple mulberry freeze-dried powder. Background technique [0002] Mulberry, also known as mulberry, is the fruit of the mulberry tree. It is green in color when tender, sour in taste, purple-black, juicy and sweet in taste when ripe. It is a dark fruit and rich in natural purple pigment. , strong kidney, nourishing yin, soothe the nerves, improve intelligence, etc., also have the reputation of "longevity fruit", "Chinese fruit emperor", "folk holy fruit". Traditional Chinese medicine has records: [0003] "Compendium of Materia Medica": Mulberry fruit is the knot of the essence of mulberry, sweet in taste and cold in nature, sweet and cold in nature, benefiting blood and removing heat, and is a medicine for cooling blood, nourishing blood and benefiting yin. -Yin benefits the five internal organs. ---Sweet and cold to remove heat, so hangover poisoning. ...
