Description

The preparation method that a kind of cowpea is done

Technical field

The present invention relates to a kind of preparation method of dried bean curd, the preparation method that particularly a kind of cowpea is done.

Technical background

Existing cowpea generally all is a vegetables in season, can only deposit under the normal temperature 3 two days and does not note slightly also can putting older and older, loses mouthfeel.Cowpea provides the good protein that is easy to digest and assimilate, and an amount of carbohydrate and multivitamin, trace element etc. can replenish the signboard nutrient of body.The contained B family vitamin of cowpea can be kept the function of normal glandula digestive secretion and gastrointestinal motility, and it is active to suppress choline enzyme, can help digest, and improves a poor appetite; Contained vitamin C ability enhancing antibody is synthetic in the cowpea, the effect that improves the body disease-resistant poison; The phosphatide of cowpea has the promotion insulin secretion, participates in glycometabolic effect, is diabetes patient's ultimate food.Flat, the sweet-salty of cowpea property is returned spleen, stomach warp, has that beneficial gas, good in strengthening stomach and tonifying kidney and the five internal organs in the reason, accent face take care of health, a production of sperm marrow, the effect of only quenching one's thirst.This explanation cowpea has very big effect in the health care of common people's daily life.

Summary of the invention

The objective of the invention is to overcome the deficiency of prior art and provide a kind of holding time is long, suitable for four seasons, nutritive value does not run off cowpea to do.

Concrete technical scheme of the present invention is: the preparation method that a kind of cowpea is done may further comprise the steps:

Step 1, select materials: select no small holes caused by worms, no rust staining, do not have the tender cowpea of deformity, not damaged, no dirt;

Step 2, blanching: tender cowpea tissue is delicate, and boiling water blanching 2-4 minute is soaked with cold water immediately after pulling out and floated;

Step 3, guarantor's look: the sodium acid carbonate that in water, adds 0.4%-0.6% during blanching;

Step 4, sulphuring: the cowpea that scalded is placed on indoor with the bamboo mat stand, presses 200g/m burning sulphur then;

Step 5, oven dry: adopt artificial drying oven dry.

Soak to float and to prevent the waste heat continuous action, can also remove the emplastic that cowpea is discharged simultaneously; Sodium acid carbonate can keep the cowpea color and luster dark green, improves the presentation quality of dried cowpea; Oxidation stain when burning sulphur can prevent the cowpea drying reduces the vitamin C loss and avoids dried cowpea to rot, and can also accelerate rate of drying, makes the rehydration performance of finished product good; Naturally dryingly tend to receive weather effect, thereby preferably adopt artificial drying oven dry.

Production technology of the present invention is simple, and cost is low, and nutritional labeling is high, is convenient to store instant.The cowpea unique flavor, nourishing yin and supplementing blood, heat-clearingization is greasy, and foster spleen is good for the stomach, and is people's the delicacies of going with rice or bread.
