Embodiment 1

[0027] Purchase a number of commercially available spicy crab products (manufacturers: Taizhou Qinhu Duan Crab Professional Cooperative, Xuyi Sizhou City Agricultural Development Co., Ltd., Wenzhou Cangnan Baoxin Food Co., Ltd., Wuhan Deyan Aquatic Food Co., Ltd.), and place them at 37°C In the incubator until the jars or bags swell. Take out the rotten and smelly spicy crab sample from the package, cut it into pieces with pre-sterilized scissors, weigh 25g in a sterilized homogenate cup, add 225ml 7.5g / L sterile physiological saline, transfer to In a sterilized 500ml Erlenmeyer flask, shake at 20°C and 100r / min for 10min and then let stand for 5min. The supernatant was diluted 10 times with sterile 7.5g / L physiological saline, and finally three suitable gradient solutions were selected, and 1ml of each gradient solution was poured on the broth medium for 48 hours. According to the appearance characteristics such as the shape, size and color of the colony, a single colony was...

Embodiment 2

[0039] (1) Crab Temporary Cultivation and Cleaning: Fresh and live crabs are selected as raw materials without dead crabs. Put a certain volume of tap water into the temporary cultivation pond, weigh citric acid until the final concentration reaches 0.3g / L, pour it into tap water, and stir to dissolve. Put the crabs into the water until they can be completely submerged, and keep soaking for 30 minutes, then remove them with a grid tool to a clean container, and drain.

[0040] (2) Blanching in boiling water: boil the water until it boils, place the crabs in a stainless steel mesh container, put them into boiling water for 5-10 seconds together, scald the crabs to death, take them out quickly, and drain.

[0041] (3) Frying: Set the oil temperature of the electric fryer to 120°C, pour in soybean oil (the solid-to-liquid ratio of crab and soybean oil is 1kg:4L) and wait until the oil temperature is heated and stabilized. Put the crabs in the frying basket and deep-fry. It is adv...

Embodiment 3

[0047] Method is the same as embodiment 2, and difference is:

[0048] The concentration of the aqueous citric acid solution in step (1) is 0.4g / L, and the dipping time is 25min;

[0049] The oil temperature of electric fryer in step (3) is 140 ℃, and frying time is 60s, and the solid-liquid ratio of crab and soybean oil is 1.8kg:4L;

[0050] In step (4), use a commercially available seasoning packet instead of seasoning (Xuyi County Xuyi Lobster Seasoning Co., Ltd., weigh the required amount and corresponding water according to the instructions), and weigh or measure an appropriate amount of ε- Polylysine hydrochloride, oregano essential oil, and distilled glyceryl monostearate, so that the final concentrations can reach 0.8g / L, 0.5ml / L, and 0.01g / L respectively, dissolve with a small amount of water, and homogenize at high speed for 20s , to obtain a uniform emulsion; pour it into a clean container, add the remaining water required and stir evenly to obtain a preservative s...

Abstract

The invention discloses a method for making spicy crabs, which comprises the following steps: (1) soaking the crabs in an aqueous solution of citric acid for temporary cultivation at room temperature, and rinsing them with clean water; (2) bathing the crabs obtained in the step (1) in boiling water, draining (3) fry the crab obtained in step (2), and drain the oil; (4) mix the preservative, auxiliary agent and seasoning liquid to obtain a pickling solution; the preservative is ε-polylysine hydrochloride Any one or both of salt and oregano essential oil; (5) soak the crab obtained in step (3) in the marinating liquid obtained in step (4) and marinate at room temperature, drain; (6) soak the crab obtained in step (4) ) obtained crabs are placed in aseptic materials for packaging, and sterilized to obtain final product. The present invention comprehensively utilizes raw material reduction bacteria, compound antistaling agent, and appropriate sterilization means to effectively prolong the shelf life of spicy crabs. The antistaling agents used are ε-polylysine hydrochloride and oregano essential oil, which can synergistically complement each other It can effectively inhibit spoilage bacteria in spicy crabs.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to a method for preparing spicy crab. Background technique [0002] Crabs are rich in nutrition and delicious in taste, and are deeply loved by the masses. They are rich in fat and protein and can be used to make various delicious dishes. Therefore, in recent years, the crab farming industry has developed rapidly and has become the most representative and influential leading industry in special aquatic products. In the process of crab breeding, a certain proportion of "old crabs", also known as stiff crabs, are often produced. The individual size is about 50-100 grams, and they mature about two months earlier than hairy crabs. The price of these old crabs is very low, generally less than 10 yuan per kilogram, but this kind of crab is not inferior crab, and the edible quality is still very good. If it cannot be used, it will be a big economic loss for the farmers. [0003...
