Embodiment 1

[0025] A kind of sweet tea powder, comprises following preparation steps:

[0026] Step 1, mix 500kg of raw milk, 92kg of maltodextrin, 19kg of white granulated sugar and 19.5kg of palm oil to obtain a mixed liquid, which is set aside.

[0027] Step 2: Homogenize the mixed solution for 9 seconds at a pressure of 250 MPa and a temperature of 62° C., and then sterilize at 90° C. for 24 seconds to obtain a sterilizing solution.

[0028] Step 3, use 2400-type double-effect falling-film evaporator to vacuum-concentrate the sterilizing solution, the vapor pressure of vacuum concentration is 5.0MPa, the first-effect temperature of 2400-type double-effect falling-film evaporator is 68°C, and the first-effect vacuum degree is - 0.065MPa, the second-effect temperature is 53°C, the second-effect vacuum is 0.085MPa, then spray-dry for 3 minutes at a pressure of 140MPa and a temperature of 82.5°C, cool to 26°C, pass through a 35-mesh sieve, and pack to obtain .

Embodiment 2

[0030] A kind of sweet tea powder, comprises following preparation steps:

[0031] Step 1, mix 450kg of raw milk, 96kg of maltodextrin, 17kg of white granulated sugar and 21kg of palm oil to obtain a mixed liquid, which is set aside.

[0032] Step 2: Homogenize the mixed solution for 8 seconds at a pressure of 200 MPa and a temperature of 64° C., and then sterilize at 95° C. for 20 seconds to obtain a sterilizing solution.

[0033] Step 3, use 2400-type double-effect falling-film evaporator to carry out vacuum concentration on the sterilizing liquid, the vapor pressure of vacuum concentration is 5.5MPa, the first-effect temperature of 2400-type double-effect falling-film evaporator is 70°C, and the first-effect vacuum degree is - 0.06MPa, the second-effect temperature is 50°C, the second-effect vacuum is 0.08MPa, then spray-dry for 1 minute at a pressure of 100MPa and a temperature of 80°C, cool to 24°C, pass through a 30-mesh sieve, and pack to obtain .

Embodiment 3

[0035] A kind of sweet tea powder, comprises following preparation steps:

[0036] Step 1, mix 550kg of raw milk, 88kg of maltodextrin, 21kg of white granulated sugar and 18kg of palm oil to obtain a mixed liquid, which is set aside.

[0037] Step 2: Homogenize the mixed solution at a pressure of 300 MPa and a temperature of 60° C. for 10 seconds, and then sterilize at 80° C. for 28 seconds to obtain a sterilizing solution.

Abstract

The present invention discloses a sweet tea powder and a preparation method thereof. The sweet tea powder comprises the following raw materials: raw milk, maltodextrin, white granulated sugar and palmoil. The preparation method comprises the following steps: step 1, mixing the raw milk, the maltodextrin, the white granulated sugar and the palm oil to obtain a mixed solution; step 2, homogenizingand sterilizing the mixed solution to obtain a sterilizing liquid; and step 3, carrying out vacuum concentration spray drying, cooling, sieving and packaging on the sterilized liquid. The sweet tea powder obtained by the method has a milky white color, has a peculiar smell and taste, is free from irritating, burnt, rancid and other peculiar smell, is good in brewing property, is free from visibleforeign impurity visible to naked eyes, accords with standard requirements of physical and chemical indexes and microbial indexes, and is simple in preparation method, low in production cost and suitable for large-scale production for enterprises.

Description

technical field [0001] The invention relates to the technical field of dairy products and processing thereof, in particular to sweet tea powder and a preparation method thereof. Background technique [0002] With the development and progress of society and the improvement of people's living standards, people's desire for health and quality of life are getting higher and higher, and the use of beverages and foods to realize this demand has become a new growth point. Protein solid drinks have the following effects: (1) promote growth and development, protein is an important component of skin, muscle, bone, hair, etc., supplementing high-quality protein is helpful for growth and development; (2) enhance immunity, immune Globulins are natural antibodies against antigens. Whey protein and its enzymatic products have regulatory effects on lymphocytes, phagocytes, granulocytes, NK cells and other immune systems; (3) maintain gastrointestinal health, high-quality protein can repair...
