AI Technical Summary

Problems solved by technology

The main problems are long production cycle, high probability of secondary pollution and reproduction of microorganisms, uneven pickling of products, and poor taste
However, long-term pickling will increase the chance of bacterial contamination and the growth and reproduction of original bacteria, increase food safety hazards, reduce the chewiness of the product, and cause the product to become soft and rotten in severe cases

Embodiment 1～7

[0022] Embodiments 1-7 Influence of Ultrasonic Frequency on Purification Process

[0023] Newly caught cockles generally carry more bacteria, and need to be stocked and purified in clean seawater for 8 to 72 hours, so that the cockles can spit out the sediment and most of the pollutants. The effects of different ultrasonic treatments on the hygienic quality of cockle purification are shown in Table 1:

[0024] Table 1

[0025]

[0026] After 8 hours of natural purification, the total number of original colonies of mud cockles increased from 4.2×10 6 down to 1.2×10 5 . Ultrasonic treatment with different intensities can reduce the number of bacteria in cockles to 1.1×10 4 ~9.1×10 4 , which should be derived from the cavitation effect of ultrasonic waves. Comparing the data in Table 1, it can be seen that low-frequency sound wave treatment is also beneficial for stimulating mud cockles to spit mud, and the suitable ultrasonic frequency is 30KHz; low temperature is benef...

Embodiment 8～12

[0028] Examples 8-12 Research on the Effect of Ozone Water Bacteria Reduction Treatment

[0029] After ultrasonic-assisted clean seawater purification treatment, the sediment of the cockles was basically discharged, and the amount of bacteria was significantly reduced. However, in order to reduce the intensity of subsequent electron beam sterilization, improve product sensory and nutritional quality, and extend shelf life, it is necessary to take bacteria reduction treatment to further reduce the total number of bacterial colonies in the product, kill pathogenic bacteria, and ensure product quality and safety.

[0030] In Example 6, the cockles treated with preliminary ultrasonic-assisted purification were centrifuged and drained, then added into ozone water of different concentrations 5 to 10 times their own weight, and soaked for 20 minutes. The bacteria-reducing effect of ozone is shown in Table 2.

[0031] Table 2

Embodiment 13～16

[0034] Examples 13-16 Research on the Effect of Vacuum Negative Pressure Impregnation Treatment

[0035] The cockles after purification and bacteria reduction treatment were treated with vacuum negative pressure impregnation, and the traditional natural soaking and pickling (7 days) was used as a control. The specific impregnation effects are shown in Table 3.

[0036] The pickling liquid is mixed with the following raw materials: 60% white wine, 14% soy sauce, 1.5% white sugar, 4.0% table salt, 0.5% monosodium glutamate, and 20% purified water.

[0037] table 3

[0038]

[0039] The most significant advantage of vacuum negative pressure impregnation is to significantly shorten the impregnation time. Due to the high content of collagen connective tissue on the surface of cockles, the pickling solution is not easy to penetrate, so it usually takes 2-7 days to soak thoroughly. Pickling for a long time will increase the chance of bacterial contamination and the breeding and ...

Abstract

The invention discloses a method for processing and preserving sauced tegillarca granosa. The method disclosed by the invention comprises the following steps: by taking tegillarca granosa temporarily cultured in purified water as a raw material, carrying out ultrasonic auxiliary purification treatment, ozone water bacterium-reducing treatment, vacuum negative-pressure immersing treatment and electron beam radiation treatment in sequence so as to obtain the sauced tegillarca granosa. According to the method disclosed by the invention, all the processes are carried out at low temperature, and the tegillarca granosa can be immersed and preserved rapidly and safely, therefore, the flavor, mouth feel and nutrition of the original fresh tegillarca granosa are kept to the most extent, and furthermore, the sanitary and quality safety can be obviously increased.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a method for processing and preserving clams with sauce. Background technique [0002] Mud clams (Tegillarcagranosa), also known as hairy clams, blood clams, flower clams, etc., belong to the mollusk phylum, bivalves, subclasses, clams, clams, and are widely distributed in the Indian Ocean and the Atlantic Ocean. It is distributed in coastal provinces such as Shandong, Fujian, and Guangdong. Clam meat is delicious, nutritious, and has high edible and medicinal value. During the Three Kingdoms period, it was recorded in "Linhai Foreign Objects" that mud cockles have the effect of "benefiting blood". "Yilin Zhuan Yao" notes: "The cockles nourish the blood of the heart, dissipate blood stasis, eliminate troubles and hangovers, break knots and eliminate phlegm." Stomach effect: Indications for blood deficiency, impotence, stomach pain, indigestion, diarrhea, pus and blood, etc. It i...
