Problems solved by technology

However, there are the following main problems in using spices to suppress spoilage bacteria in salted duck. First, the composition of spices that can effectively inhibit spoilage bacteria in salted duck needs to be screened and optimized to determine; second, granular spices, spice essential oils or oleoresin It is difficult to mix evenly with the raw duck during pickling; third, powdery spices still contain more cellulose and lignin, and there is a problem that the effective ingredients penetrate slowly into the duck body during pickling; fourth, powdery spices Fine debris will adhere to the surface of the duck body, and it is time-consuming and water-consuming to clean, and it is difficult to clean, which will affect the appearance of the salted duck product

Embodiment 1

[0033] Grind the mixed spices with a weight ratio of 30% licorice, 25% cloves, 25% cinnamon and 20% Angelica dahurica, pass through a 30-mesh sieve, add 50% (v / v) ethanol aqueous solution that is 20 times the weight of the spice powder, and set the temperature at 50 ° C. Soak for 3h, after press filtration, obtain the spice extract, add the spice extract of 2 times its weight in the salt, and add the beta-cyclodextrin of 5% of salt weight and the maltodextrin of 5% respectively, through Boil with high-pressure steam, heat and concentrate, recover ethanol, stir while heating, the peripheral speed of the outer edge of the anchor stirrer blade is 0.6m / s, until the water is dry, the material is completely crystallized, and the spice salt co-crystal embedding is obtained. The spice salt co-crystal embedding is pulverized, passed through a 30-mesh sieve, weighed, and packed into bags to obtain a finished product of spice salt that inhibits Enterococcus gallinarum in salted duck witho...

[0036] Grind the mixed spices with a weight ratio of 30% licorice, 25% cloves, 25% cinnamon and 20% Angelica dahurica, pass through a 30-mesh sieve, add 50% (v / v) ethanol aqueous solution that is 20 times the weight of the spice powder, and set the temperature at 65°C Soak for 2 hours, press filter to get the spice extract, add 3 times the weight of the spice extract to the salt, and add 5% of the salt weight β-cyclodextrin, 7.5% of the maltodextrin and 5% of the salt The monosodium glutamate is boiled by high-pressure steam, heated and concentrated, ethanol is recovered, stirred while heating, the peripheral speed of the outer edge of the anchor stirrer blade is 0.7m / s, until the water is dried, the material is completely crystallized, and the spice salt co-crystallization is obtained. The embedding material, the co-crystal embedding material of the spice salt is crushed, passed through a 30-mesh sieve, weighed, and bagged to obtain a finished product of spice salt that inhibi...

Embodiment 3

[0039] Grind the mixed spices with a weight ratio of 30% licorice, 25% cloves, 25% cinnamon and 20% Angelica dahurica, pass through a 20-mesh sieve, add 50% (v / v) aqueous ethanol solution that is 10 times the weight of the spice powder, and set the temperature at 70°C Soak for 2 hours, after pressure filtration, add 50% (v / v) ethanol aqueous solution 10 times the weight of spice powder to the spice residue, soak at 70°C for 2 hours, after pressure filtration, combine the spices obtained by two extractions Extraction solution, after two extractions, the active ingredients in the spices are extracted more fully, add the spices extraction solution of 2 times its weight in table salt, and add β-cyclodextrin of 5% by weight of table salt and 5% by weight of table salt The maltodextrin is boiled by high-pressure steam, heated and concentrated, ethanol is recovered, and stirred while heating, the peripheral speed of the outer edge of the anchor stirrer blade is 0.6 m / s, until the wate...

Abstract

The invention relates to a method for preparing a spice salt for inhibiting chicken enterococcus in salted preserved duck. The method comprises the following steps: 1) pulverizing a mixed spice of liquorice, clove, cinnamon and radix angelicae, sieving, adding an ethanol solution, the weight of which is 10 to 30 times that of the spice powder, soaking at 30 to 80 DEG C for 2-5 hours, and carryingout pressure filtration, so as to obtain spice extract liquid; 2) adding the spice extract liquid, the weight of which is 1 to 6 times that of salt, to the salt, separately adding beta-cyclodextrin, the weight of which accounts for 2% to 10% of that of the salt, and maltodextrin, the weight of which accounts for 2% to 10% of that of the salt, to the salt, boiling and heating for concentrating, recovering ethanol, and heating while stirring until moisture is totally dried and the material is completely crystallized, so as to obtain a spice salt co-crystal embedding material; and 3) crushing andsieving through a 30-mesh sieve. The method can effectively prevent the loss of anti-bacteria and antioxidant components in spices, active components can be evenly distributed on the surface of a duck body with the salt and penetrate into the duck body fast, the surface of the duck body has no fines of spices and does not need to be cleaned, and thus the standardized green production of salted preserved duck is easy to be realized.

Description

technical field [0001] The invention belongs to the technical field of food processing and relates to the preparation of a spice salt for inhibiting Enterococcus gallinarum in salted duck. Background technique [0002] Salted duck is one of the famous traditional native products in my country. It is a good product of cured meat and has a production history of thousands of years. Although the processing techniques vary from place to place, they are all made by fattening ducks and marinating them with salt. The traditional salted duck is produced in winter, the amount of salt used is as high as 10%, and the storage period is 3-6 months. Because it is mainly produced in handicraft workshops, and often due to poor sanitation control, the microbial content exceeds the standard. As the temperature rises, Microorganisms multiply rapidly, causing salted duck to rot. Studies have shown that Enterococcus gallinarum ( Enterococcus gallinarum ), Enterococcus faecalis ( Enterococcus...
