Embodiment 1

[0038] Such as figure 1 Shown, a kind of production method of quick-frozen bamboo shoots is:

[0039] (1) Raw material processing: As the key to the quality of quick-frozen bamboo shoots, the raw materials must be purchased strictly. The raw materials should not be unearthed and pre-cooked for more than 12 hours. After entering the factory, the raw materials should be piled up in the sunshade, and should not be exposed to the sun, and should not be stacked too high. , The purchase quantity of raw materials should conform to the actual digestion capacity of the factory, so as to avoid untimely processing of raw materials. The length of raw materials should be controlled within 2.5 times of the diameter of the bottom, and there should be no insect shoots or overnight shoots;

[0040] (2), Cooking: Cook the raw materials again, set the temperature at 100°C, and the actual temperature is 98°C±2°C. The weight of a single bamboo shoot is: 2.1-4kg and needs to be heated for 60 minu...

Embodiment 2

[0054] Such as figure 1 Shown, a kind of production method of quick-frozen bamboo shoots is:

The raw materials should not be unearthed and pre-cooked for more than 12 hours. After entering the factory, the raw materials should be piled up in the sunshade, and should not be exposed to the sun, and should not be stacked too high. , The purchase quantity of raw materials should conform to the actual digestion capacity of the factory, so as to avoid untimely processing of raw materials. The length of the raw material should be controlled within 2.5 times of the diameter of the bottom, and there should be no insect shoots or overnight shoots;

[0056] (2), Cooking: Cook the raw materials again, set the temperature at 100°C, and the actual temperature is 98°C±2°C. The weight of a single bamboo shoot is: 2.1-4kg and needs to be heated for 60 m...

Embodiment 3

[0070] Such as figure 1 Shown, a kind of production method of quick-frozen bamboo shoots is:

[0071] (1) Raw material processing: As the key to the quality of quick-frozen bamboo shoots, the raw materials must be purchased strictly. The raw materials should not be unearthed and pre-cooked for more than 12 hours. After entering the factory, the raw materials should be piled up in the sunshade, and should not be exposed to the sun, and should not be stacked too high. , The purchase quantity of raw materials should conform to the actual digestion capacity of the factory, so as to avoid untimely processing of raw materials. The length of the raw material should be controlled within 2.5 times of the diameter of the bottom, and there should be no insect shoots or overnight shoots;

[0072] (2), Cooking: Cook the raw materials again, set the temperature at 100°C, and the actual temperature is 98°C±2°C. The weight of a single bamboo shoot is: 2.1-4kg and needs to be heated for 60 m...

Abstract

The invention relates to a quick-frozen bamboo shoot production method, comprising the following steps: (1) treatment of raw materials, namely, selecting fresh bamboo shoots and removing impurities; (2) sterilization, namely, carrying out routine sterilization on the treated bamboo shoots; (3) quick-freezing, namely, quick-freezing the bamboo shoots one by one with a quick-freezing machine, controlling the quick-frozen temperature at -30 to -35 DEG C, and discharging the bamboo shoots when the center temperature of the bamboo shoots drops below -18 DEG C; (4) ozone water ice-plating, namely, the quick-frozen bamboo shoots are soaked in ozone ice water for 7-20 seconds at an oxidation reduction potential of 300mv-600mv, and then quickly taking out the bamboo shoots; and (5) packaging, namely, vacuum-packaging the ozone ice-plated bamboo shoots, wherein, the oxidation reduction potential of the ozone water is 500mv, and the bamboo shoots are soaked in the ozone water for 10 seconds. The application of the method greatly reduces the total number of bacteria of bamboo products, effectively maintains the freshness of the bamboo products, prolongs the shelf life and reduces the contents of toxic and harmful substances.

Description

(1) Technical field [0001] The invention relates to a production method of quick-frozen bamboo shoots. (2) Background technology [0002] Bamboo shoots are delicious, nutritious, and have the effects of cooling and relieving heat, lowering blood pressure, and lowering fat. They are a kind of natural health food. Quick-frozen bamboo shoots are very popular in the international market because they can well maintain the flavor, nutrition and health benefits of fresh bamboo shoots. Due to the current localization of quick-freezing equipment, many food companies in Fujian, Guangdong and other provinces along the southeast coast of my country have been engaged in the production of quick-frozen bamboo shoots and exported them to Europe, America and Southeast Asian countries, with considerable economic benefits. [0003] The method of producing quick-frozen bamboo shoots is roughly divided into 3 kinds at present: (1) after fresh bamboo shoots are checked and accepted, carry out cl...
