Insect prevention formula for ham and salted dried fish and use method thereof

Abstract

The invention relates to an insect prevention formula for ham and salted dried fish and a use method thereof. The formula is as follows: one liter of water or ethanol solution with light concentration contains 50mg to 300mg of matrine, or the content of matrine in one liter of water or ethanol solution with light concentration is reduced to 10mg to 50mg, and then 20mg to 100mg of azadirachtin or natural pyrethrum is added. The use method comprises the following steps: after being salted and before air-drying, the fish is washed, immersed into the solution prepared according to the formula for 5 minutes to 30 minutes and then taken out for air-drying; and after being salted and before air-drying, the ham is washed, immersed into the solution prepared according to the formula for 5 minutes to 30 minutes and then taken out for air-drying, and goes through the subsequent processing of traditional technique. The insect prevention formula completely adopts natural plant extracts for insect and fly prevention, does not relate to any synthetic chemical pesticide, has easy operation and insect prevention rate higher than 98 percent, and fully retains the traditional flavor and color and lustre of the ham and the salted dried fish, with only 0.4 yuan per kilogram of cost increase; and besides ensuring the traditional sensory quality of the ham and the salted dried fish, the insect prevention formula causes no potential safety hazard and can be applied in large scale.

Description

technical field [0001] The invention belongs to the technical field of light industrial food processing and preservation, and relates to an anti-insect formula in the processing of ham and carp and an application method thereof. Background technique [0002] Ham and fish are traditional animal foods in my country. Their traditional processing involves pickling and drying in the open air, so they are particularly easy to attract flies and moths. Fly stings and insects not only reduce the sensory quality of ham and fish, leading to a decline in their commodity value, but also spread pathogenic microorganisms and pose a safety risk to consumers. In order to prevent fly stings and moth bites, it has recently been discovered in my country that some operators have added pesticides trichlorfon or dichlorvos during processing. Regarding the anti-fly and anti-moth methods for ham and fish processing, the chemical control method commonly used abroad is to impregnate with pyrethroids ...

Problems solved by technology

In my country, there has been a patent application for the application of chlorine dioxide to prevent flies. Another report believes that the flies that harm ham can be effectively controlled by changing the process. There is no formula that is safe, effective, easy to operate, low cost, and does not affect the flavor of the product.
