Abstract
The invention provides a method for preparing lotus seed starch sponge, comprising the following steps: starch cloudy liquid preparation, gelatinization, frozen storage, unfreezing and centrifugation draining. Aiming at preparing the lotus seed starch sponge in such a method that the gelatinized lotus seed starch is denatured to be in a sponge form by the processes of frozen storage and unfreezing, and then the sponge-form lotus seed starch is centrifugally filtered and dried, thus the invention explores a new way for processing and utilizing lotus seed starch. The invention has low requirements for equipment and strong manipulability and is applicable to the large-scale industrial production of the lotus seed starch sponge.
Description
Technical field
The invention belongs to the application of starch, more specifically relating to a kind of is the method for feedstock production starch sponge with the lotus seed starch.
Background technology
Lotus seeds are fruits and seedses of Nymphaeceae nelumbium, are the medicine-food two-purpose resources of China's high-quality.Contain a large amount of starch in the lotus seeds, average content reaches 41%.Lotus seed starch belongs to the specificity starch of high amylose content, and relevant its application is more rare.
Summary of the invention
The preparation method who the purpose of this invention is to provide a kind of lotus seed starch sponge, this preparation method is to be raw material with the lotus seed starch, be processed into starch sponge through special process, because of it has stronger water imbibition and network structure, the base material that can be used as styptic sponge, also can be used as the edibility filler, for a new outlet is opened up in the application of lotus seed starch; And equipment is less demanding, and is workable, produces environment friendly and pollution-freely, with low cost, has remarkable economic efficiency.
The preparation method of lotus seed starch sponge of the present invention is characterized in that: comprise starch cloudy liquid preparation, gelatinization, cold storage, thaw, centrifugal filter does; Concrete steps are as follows:
(1) starch cloudy liquid preparation: take by weighing starch, and the adding suitable quantity of water is deployed into the muddy liquid of starch;
(2) the muddy liquid of deployed starch being carried out boiling water bath, to be heated to gelatinization complete;
(3) gelatinized corn starch after the gelatinization is carried out cold storage;
(4) with the gelatinized corn starch after the cold storage as for thaw under the normal temperature starch sponge;
(5) centrifugal filter is done: the starch sponge after will thawing obtains filtering dried lotus seed starch sponge after centrifugal.
Remarkable advantage of the present invention is:
(1) the present invention adopts lotus seed starch as raw material, because lotus seed starch belongs to the specificity starch of high amylose content, so the lotus seed starch after the gelatinization is stuck with paste and formed spongy by cold storage, the technology sex change of thawing; The lotus seed starch sponge that after centrifugal filter is done, obtains having stronger water imbibition and network structure, product purpose of the present invention is extensively sent out, the base material that can be used as styptic sponge also can be used as the edibility filler, for the processing and utilization of lotus seed starch provides scientific guidance and reference.
(2) present device is less demanding, and is workable, and produces environment friendly and pollution-freely, with low cost, has remarkable economic efficiency.

Fig. 1 is a process chart of the present invention.
The specific embodiment
In order fully to disclose the preparation method of lotus seed starch sponge of the present invention, be illustrated below in conjunction with embodiment.
Embodiment
The preparation method of lotus seed starch sponge comprises the steps:
(1) starch cloudy liquid preparation: take by weighing starch according to a certain percentage, and add entry and be deployed into the muddy liquid of starch;
(2) the muddy liquid of deployed starch being carried out boiling water bath, to be heated to gelatinization complete;
(3) gelatinized corn starch after the gelatinization is carried out cold storage;
(4) with the gelatinized corn starch after the cold storage as for thaw under the normal temperature starch sponge;
(5) centrifugal filter is done: the starch sponge after will thawing obtains filtering dried lotus seed starch sponge after centrifugal.
Described starch addition is 2%-8% (W/V), and in below-4 ℃, more than the cold storage 24h, after normal temperature thawed, under the 3000-4500r/min condition, centrifugal 10min obtained filtering dried lotus seed starch sponge to starch again after abundant gelatinization.
