Embodiment 1

[0013] A treatment method for lotus seed juice paste gelatinization, which is to wash the fresh lotus seeds with full grains, no browning and complete core with flowing water; then add clean cold water to the lotus seeds, and use a stainless steel refiner to process them through 100 meshes. The first step of refining, and then the second step of refining through 120 mesh to obtain the lotus seed pulp; the obtained lotus seed pulp is heated to 85°C through a plate heat exchanger, and then injected into a high-shear gelatinization tank, The high-speed shearing machine was turned on and interlayer heating was carried out simultaneously, so that the lotus seed paste was gelatinized at a constant temperature for 30 minutes under the conditions of 85° C. and 2880 rpm high-speed shear to obtain the lotus seed juice that had been gelatinized in the whole paste.

Embodiment 2

[0015] A treatment method for lotus seed juice paste gelatinization, which is to wash or thaw fresh lotus seeds with full grains, no browning and complete core with flowing water; The first stage of refining is carried out, and then the second stage of refining is carried out through 120 mesh to obtain the lotus seed pulp; the obtained lotus seed pulp is heated to 90°C through a plate heat exchanger, and then injected into the high-shear gelatinization tank In the process, the high-speed shearing machine was turned on and interlayer heating was carried out simultaneously, so that the whole lotus seed pulp was gelatinized at a constant temperature for 25 minutes under the conditions of 92 ° C and 2880 rpm high-speed shear, and the lotus seed juice that had been gelatinized in the whole paste was obtained.

Embodiment 3

[0017] A treatment method for the gelatinization of lotus seed juice, which is to thaw the quick-frozen lotus seeds with full particles, no browning and complete core; then add clean cold water to the lotus seeds, and use a stainless steel refiner to carry out the first step through 100 mesh Refining, and then conduct the second refining through 120 mesh to get the lotus seed pulp; heat the obtained lotus seed pulp to 95°C through a plate heat exchanger, then pour it into the high-shear gelatinization tank, and turn on the high-speed shear Cut the machine and simultaneously carry out interlayer heating, so that the whole lotus seed paste is gelatinized at a constant temperature for 20 minutes under the conditions of 100 ° C and 2880 rpm high-speed shear to obtain the lotus seed juice that has been gelatinized in the whole paste.

[0018] The present invention combines the application of whole fruit refining, whole paste gelatinization and high-speed shearing technology to proce...

Abstract

The present invention discloses a treating method of lotus seed juice full slurry gelatinizing. The method is as follows: clean cold water is added into fresh lotus seeds or quick-frozen lotus seeds, the lotus seeds are subjected to a first slurry grinding at 100 meshes, then the ground lotus seeds are subjected to a second slurry grinding at 120 meshes to obtain a lotus seed full slurry, then the obtained lotus seed full slurry is subjected to a temperature rising by a plate heat exchanger to be 85 DEG C-95 DEG C, then heated lotus seed full slurry is subjected to an interlayer heating method, and the lotus seed full slurry is gelatinized at a constant temperature of 85 DEG C-100 DEG C and a high-speed shearing condition at 2,880 rpm for 20 min-30 min. The technology can solve the problems that in the production of the traditional lotus seed juice drink, the raw material utilization rate is not high, and the lotus juice drink produced by the traditional technology is easy to produce wall sticking, pot burning, coking, etc. due to the contained starch and proteins, effectively enhances the processing quality and nutritional quality of the lotus seed juice drink product, provides stable and fully gelatinized lotus seed raw juice for the follow-up lotus seed juice drink production, and can be promoted to the production of the drink products using high starch content fruits and vegetables as the main raw materials.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a treatment method for gelatinizing lotus seed juice. Background technique [0002] Lotus seeds are the seeds of Nymphaeaceae, and they are high-quality medicinal and edible resources in my country. Lotus seeds are foods with high starch content. The average starch content in fresh lotus seeds is about 15%~25%. Due to the special properties of amylose contained in lotus seeds, lotus seed juice beverages made with lotus seeds as the main raw material are very prone to starch reversion. However, there are phenomena such as stratification and precipitation, and the shelf life is extremely short, and it is easy to lose its commodity value. On the basis of the beverage production process, the present invention develops a gelatinization process of whole paste of lotus seed juice, which can improve the utilization rate of raw materials and product stability, and pro...
