preparation example Construction

[0023] The invention provides a preparation method of jujube puree rich in dietary fiber and polysaccharide, comprising the following steps:

[0024] 1) The red dates after beating are sieved for the first time to obtain the liquid that removes the jujube skin and the date core residues, and the second sieve is performed, the filtrate is red date juice, and the filter residue is a mixture of red date pulp and dietary fiber; The condition of the sieve is to filter with a 100-mesh and a 300-mesh filter in turn;

[0025] 2) Treat the jujube juice obtained in step 1) at 98-102° C. for 8-12 minutes, cool down, let stand, and separate to obtain the jujube juice precipitate;

[0026] 3) The mixture of jujube pulp and dietary fiber obtained in step 1) is mixed with the jujube juice precipitation obtained in step 2), and beaten to obtain jujube puree rich in dietary fiber and polysaccharides.

[0027] The red dates after beating are first sieved to obtain the liquid that removes the j...

Embodiment 1

[0034] 1) Dried jujube softened

[0035] Use dried jujube as raw material, select dried jujube with plump flesh and no black spots, add water with 3.0 times the mass of the raw material, soften at 100°C for 10 minutes, then add (immediately add) cold water with 3.0 times the mass of the raw material (thus realizing softening rapid cooling of jujubes) to obtain softened jujubes.

[0036] 2) Preparation of jujube pulp and fiber tissue

[0037] The softened red dates obtained in step 1) are beaten with a broken wall cooking machine at 34000r / min for 80s to obtain red date pulp; then filtered with a 40-mesh filter to remove the residue of jujube skin and date core, and then filtered with 100-mesh and 300-mesh filters in turn , collect 100 mesh and 300 mesh filtered residues and mix them for later use (the main components are jujube pulp and dietary fiber, such as figure 2 Shown, its moisture content is 52.18%, soluble sugar content 10.22%).

[0038] 3) Juice Precipitation Prep...

Embodiment 2

[0043] 1) Dried jujube softened

[0044] Use dried red dates as raw materials, choose dried red dates with full flesh and no black spots, add water 2.5 times the weight of the raw materials, soften at 100°C for 10 minutes, and then add (immediately add) cold water 3.5 times the weight of the raw materials (so as to achieve softening) rapid cooling of jujubes) to obtain softened jujubes.

[0045] 2) Preparation of jujube pulp and fiber tissue

[0046] The softened red dates obtained in step 1) are beaten with a broken wall cooking machine at 32000r / min for 90s to obtain red date pulp; then filtered with a 40-mesh filter to remove the residue of jujube skin and date core, and then filtered with 100-mesh and 300-mesh filters in turn , collect the residue that 100 orders and 300 orders are filtered and mix standby (its main component is jujube pulp and dietary fiber, and its moisture content is 53.24%, soluble sugar content 10.41%)

Abstract

The invention relates to red date puree rich in dietary fibers and polysaccharide and a preparation method thereof, and belongs to the technical field of puree preparation. The preparation method of the red date puree rich in the dietary fibers and the polysaccharide comprises the following steps of (1) performing primary sieving on pulped red dates to obtain liquid without date peel and date pit residues, and performing secondary sieving to obtain a filtrate which is red date juice and a filter residue which is a mixture of red date pulp and the dietary fibers; (2) treating the red date juice obtained in the step (1) at 98-102 DEG C for 8-12 minutes, cooling, standing and separating to obtain red date juice precipitates; and (3) mixing the mixture of the red date pulp and the dietary fibers obtained in the step (1) with the red date juice precipitates obtained in the step (2), and pulping to obtain the red date puree rich in dietary fibers and the polysaccharide. According to the preparation method of the red date puree rich in the dietary fibers and the polysaccharide, jujube juice processing byproducts are fully utilized, the production cost is low, the additional value of red jujube processing is increased, and prepared red jujube puree products are high in dietary fiber content, high in red jujube polysaccharide content and high in health-care function value.

Description

technical field [0001] The invention relates to the technical field of fruit puree preparation, in particular to jujube puree rich in dietary fiber and polysaccharides and a preparation method thereof. Background technique [0002] Jujubes are rich in biologically active substances that are beneficial to human health, such as polysaccharides, cAMP, saponins, alkaloids, flavonoids and triterpenoids, etc. Efficacy such as committing suicide and prolonging life. Modern scientific research shows that jujube also has the functions of anti-cancer, lowering blood pressure, calming the nerves, protecting the liver, preventing cardiovascular and cerebrovascular diseases, improving memory and improving immunity. The natural health food that takes into account is also listed as a medicinal and edible plant by the National Health and Family Planning Commission. [0003] Fruit puree is another form of fruit, which has the characteristics of convenient consumption, long shelf life and h...
