Making method of original-taste rapid-expansion instant tremella slices

Abstract

The invention discloses a making method of original-taste rapid-expansion instant tremella slices. The method comprises the steps that tremella fruiting bodies are cleaned to remove impurities and then soaked in tap water of which the pH value is regulated, soaking is conducted at 20 DEG C to 30 DEG C till tremella fully absorbs water and expands, the expanded tremella is washed with tap water, slicing is conducted, and the tremella slices are obtained; the tremella slices are steamed with steam under the conditions of 0.15 MPa and 126 DEG C, decompression and degassing are conducted rapidly, vacuum microwave drying is conducted under the conditions of 2.45 GMHz and 60 DEG C till the mass water content is below 9%, and the original-taste rapid-expansion instant tremella slices are obtained. According to the making method, water is reduced by 40%, the production time per batch is about 6 hours, the average time is reduced by 60% or above compared with a frozen ultrasonic processing method, average energy consumption is reduced by 30% or above, and the tremella slices can well keep the special fragrance. The tremella slices expand rapidly by being soaked with boiling water with the temperature of 95 DEG C or above for more than one minute, and the time is shortened by at least 10 times or above compared with tremella slices processed through a conventional method.

Description

[0001] (1) Technical field [0002] The invention relates to the preparation of white fungus slices, in particular to a preparation method of original-flavored instant white fungus slices. [0003] (2) Background technology [0004] Tremella (Tremella), commonly known as white fungus and white fungus, is a traditional and precious nutritional tonic product in my country. It is also a product that prolongs life for royal nobles in all dynasties. It is rich in protein, fat, 17 kinds of amino acids and calcium, phosphorus, iron, potassium, Sodium, magnesium, sulfur and other minerals, and rich in tremella polysaccharides and colloids and other functional ingredients, so tremella has the functions of moistening the lungs, promoting body fluid and relieving cough, nourishing yin and nourishing the stomach, clearing away heat and moistening dryness, nourishing qi and calming the nerves, strengthening the heart, nourishing the kidney and strengthening the brain It is very suitable for t...

Problems solved by technology

This method of eating tremella is time-consuming and labor-intensive, and is not suitable for the fast-paced modern life requirements, especially among young people, the pace of life is fast, and it is impossible to spend so much time and energy on it, which greatly affects the Market consumption of white fungus products

[0006] Of course, there are also canned white fungus and white fungus soup on the market. Although they are relatively convenient to eat, they are bulky, heavy, and inconvenient to carry. Many canned white fungus products on the market are difficult to open when eating, or even difficult to open. Not suitable for women and elderly friends, the market sales are not ideal

[0007] Chinese patent CN103719521A discloses a method for making instant white fungus. The focus of the making method is sugar cooking, preparation of powdered sugar, and sugar coating. The process is very cumbersome, the energy consumption is high, and the formula is complicated, and the actual production operability is poor

[0008] Chinese patent CN103610030A introduces instant dried white fungus and its production method, which is characterized in that fresh white fungus is frozen for 12-14 hours under the condition of -10°C to -25°C and microwave vacuum freeze-dried, then vacuum-packaged, the method of freezing equipment The investment is large, and the freezing time is as long as 12-14 hours, which consumes time and energy

This method uses ultrasonic waves to break the tremella cells, and the tremella will be smashed, coupled with high-temperature steam aging, the tremella cannot maintain its original shape, which will greatly affect the appearance quality, and at the same time, the ultrasonic equipment requires a large investment and takes a long time, which is not conducive to continuous production.
