Detailed Description
Example (b):
the flow chart of the method of the present invention is shown in fig. 1, and the extraction method of the turnip extract of the present invention comprises the following steps:
1) pre-treating;
2) crushing;
3) squeezing to obtain fresh juice and residue;
4) filtering the fresh juice;
5) concentrating the filtered fresh juice;
6) spray drying the fresh juice to obtain extract.
The pretreatment method in the step 1) comprises cleaning, sorting and air drying.
The crushing method in the step 2) is to use a hammer crusher and then use a juicer to take juice.
The method for filtering the fresh juice in the step 4) is to filter by using a rotary vibration sieve of 100 meshes to 120 meshes.
Filtering the fresh juice in the step 1).
The residue obtained in the step 3) is processed, and the specific steps are as follows:
31) adding hot water into the residue;
32) performing hot percolation;
33) filtering to obtain filtrate and filter residue;
34) concentrating the filtrate;
35) spray drying the concentrated filtrate to obtain extract.
The step 31) is to add 1.5 to 2 times of hot water into the residue.
And (4) treating the filter residue obtained in the step 33), wherein the specific steps are the same as the steps for treating the residue.
The method for performing heat percolation in the step 32) is to perform dynamic percolation by using 1.5-2 times of hot water with the temperature of 60-80 ℃.
The method for concentrating the filtrate in the step 34) is to concentrate the filtrate at a low temperature of between 50 and 60 ℃ by using a vacuum concentrator.
The specific embodiment of the invention is as follows:
example 1:
taking 123 kg of turnip rootstocks, pretreating, crushing, wherein the diameter phi of the crushed rootstocks is less than 0.5cm, juicing to obtain 72.1kg of fresh juice, filtering by using a rotary vibrating screen with 100 meshes to obtain the fresh juice with the relative density of 1.02 (measured at room temperature) and the sugar degree of 5.2% (measured by sugar degree), and performing spray drying after concentration to obtain 30: 1.7 kg of water-soluble extract (30: 1 means 30 kg of extract from 1kg of raw material), and concentrating at low temperature of 50 ℃ using a vacuum concentrator.
Adding 1.5 times of hot water into the residue (mass volume ratio is 1: 1.5), performing thermal percolation at 60 deg.C, filtering with 100 mesh rotary vibration sieve to obtain filtrate, concentrating, and spray drying to obtain 100: 1.3kg of water-soluble extract (1 kg of extract per 100 kg), and radix Brassicae Rapae contains polysaccharides, saponins and flavonoids as main ingredients.
Reprocessing the filter residue, wherein the processing method is the same as the residue processing method, and 300 is obtained: 1 water soluble extract 0.4 kg.
Grade differentiation of the same batch of raw material products: the extraction solid obtained by respectively collecting fresh juice spray and extracting solution spray from the same batch of raw materials is divided into two grades, the former has no high-temperature extraction process, the easily decomposed components are heated and are retained, the latter has lower temperature control than the extraction temperature (the temperature is lower than 100 ℃ by heating and boiling), the process time of low residue content percolation can be synchronous with the juice extraction, the time of the process is also shorter than that of the extraction method, the water consumption is greatly lower than that of the extraction process, and the concentration time is also shortened, so that the retention degree of the thermally decomposed components is relatively lower than that of the juice extraction, but still better than that of the extraction method.
The sugar content measured by directly extracting juice is 5.2 degrees, the concentration is higher than 2 degrees of 3-5 times of water extraction, the obtained water amount is less, and the concentration time is shorter than that of water extraction liquid (the concentration can be not concentrated, the conditions of direct spray drying are met, and the process adopts low-temperature concentration and then spray drying in consideration of investment and operation cost of spray drying). The juicing production period is shorter than that of a water extraction process, the processing capacity of the existing juicer per hour completely meets the production requirement, the solid powder can be obtained by spray drying in large-scale production on duty, and the advantages are obvious compared with that of a water extraction concentration process period.
The method has the advantages of direct juicing, high concentration, short concentration time and short production period, retains the effective components of the product as much as possible, and effectively distinguishes the grade of the product by combining the residue heat percolation with the same batch of raw materials so as to adapt to different requirements of the market. Meanwhile, the problem of low water consumption is solved; the energy consumption and the operating cost are low: the equipment volume is small and the investment is low on the premise of keeping the yield unchanged.
