Embodiment 1

[0020] 1. Raw material pretreatment: clean the fresh Zheer root.

[0021] 2. Slicing: Cut the cleaned folded ears into short strips with a length of 5cm.

[0022] 3. Color protection: immerse the cut ear root in the color protection solution with the formula: 0.8% vitamin C, 0.5% citric acid, and 0.15% sodium bisulfite, and the balance is water. The above are the percentages by mass. Soak for 10min.

[0023] 4. Blanching: Take out the folded ear root piece in the color protection solution, and blanch in 70°C water for 5 minutes.

[0024] 5. Vacuum impregnation: immerse the blanched Zheergen slices in the impregnating solution with the formula: 5% sucrose, 1% NaCl, and the balance is water. The above are the percentages by mass. The ratio of liquid to liquid (g / mL) is 1:3, adjust the vacuum degree to 0.075MPa, and vacuum impregnate for 1h.

Abstract

The present invention provides a preparation method of vacuum low temperature oil-fried crisp houttuynia cordata. Fresh houttuynia cordata is used as a raw material, the houttuynia cordata is firstly washed clean, the washed houttuynia cordata is cut into segments, the cut houttuynia cordata is subjected to a color protection, the color protected houttuynia cordata is blanched, the blanched houttuynia cordata is vacuum soaked, the vacuum soaked houttuynia cordata is quick-frozen, and then the crisp houttuynia cordata is prepared by the vacuum low temperature oil-frying technology. The preparation method solves the problems that the houttuynia cordata is relatively single in processing methods, cannot be processed, produced and sold in large scales, and relatively large in loss of nutrition after the processing, which is not conducive to the development of the houttuynia cordata food industry. The preparation method of the vacuum low temperature oil-fried crisp houttuynia cordata belongs to the field of food processing.

Description

technical field [0001] The invention relates to a method for preparing crispy Zheer root, which belongs to the field of food processing. Background technique [0002] Zheergen, scientific name Houttuynia cordata, can be used as medicine. It has a unique smell and is a wild vegetable in Sichuan, which is deeply loved by the local people and has strong local characteristics. Zheer root has high nutritional value. In addition to protein, fat, and carbohydrates, it also contains methyl n-king ketone, caprylic acid, and myrcene. It has the functions of clearing away heat and detoxifying when used as medicine. [0003] With the continuous improvement of people's living standards, the requirements for food are getting higher and higher. They are no longer only satisfied with the aspects of color, aroma, and taste, but also require food health and nutrition. At present, the processing method of zheergen is relatively simple, which cannot be processed and sold in batches, and the n...
