Abstract

The present invention relates to a method for removing residual pesticide from picked fruit and vegetable and increasing fruit and vegetable quality via enzyme preparation. The fruits and the vegetables are soaked in papain or/and bromelin preparation for 5 to 15 minutes and are cleaned by clear water. The enzyme preparation is composed of 1 to 600 portions of papain, 0 to 500 portions of bromelin, 1 to 300 portions of sodium bicarbonate according to the weight portion, wherein the activity of the papain is 20 to 300 myriad of ultraviolet unit/gram, and the activity of the bromelin is 20 to 60 myriad forint unit/gram. The enzyme preparation of the present invention is used for processing the fruits and the vegetables so as to remove residual pesticide on the fruits and the vegetables, the enzyme preparation can also hydrolysize the self protein of the fruits and the vegetables so as to tenderize the fruits and the vegetables and increase the quality of the fruits and the vegetables.

Description

Remove the method for pesticide residue on picked melon and fruit and the clean-out system of use

The present invention relates to zymin or detergent applications, specifically is a kind of method of removing pesticide residue on picked melon and fruit of cleaning with the vegetable-protein zymin.

Along with the raising of people's living standard, environmental consciousness strengthens gradually, not only will satisfy quantity to food, more stresses quality.But science and technology development, arviculture will obtain higher output, need to use various chemical substances, especially chemical pesticide, have certain residual period after the dispensing of these agricultural chemicals, and remain in the fruit and vegetable after gathering, people are edible residual the fruits and vegetables of agricultural chemicals are arranged after, can cause damage to health, even bring the harm of life.Remain in the remains of pesticide of adopting on the fruit and vegetable of back in order to remove, in recent years, people adopt various chemicals to clean, though can remove the part remains of pesticide, but clean-out system itself contains sodium alkyl benzene sulfonate usually, chemical substances such as Sodium dodecylbenzene sulfonate, these materials all have carcinogenic and help the cancer effect, thereby in use produce the secondary chemical pollution again.

The object of the present invention is to provide a kind of new removal to adopt the method for back fruit and vegetable remains of pesticide, this method adopts edible pure natural scavenging agent, has except that residual effective, non-stimulated to human body skin, harmless to article, environmentally safe also can improve the eating quality of fruit and vegetable after the use.

The scheme that the object of the invention realizes is: adopt papoid or/and Bromenzyme is made clean-out system, put it into soak fruit and vegetable 5-15 minute that needs to handle in the water after, wash down with clear water again and get final product.Papoid that is adopted or bromeline all are to extract from papaya or pineapple fruit, are pure natural substance, and be harmless, can not cause second environmental pollution.Adopting plant protease clean-out system soaking and washing to adopt the back fruit and vegetable, is the hydrolytic action of utilizing proteolytic enzyme, directly decomposes the lip-deep residuals of fruit and vegetable, reaches the effect of removing materials such as remains of pesticide.According to surveying and determination, can remove and adopt consequence vegetable grower medicine residual rate 56-99.06%.Simultaneously, in treating processes, plant protease is the protein of direct water fresh fruit vegetables itself also, reaches the effect of tenderization fruits and vegetables, and fruit and vegetable after treatment are more tender and crisp when edible, deliciousness.

Enzyme clean-out system of the present invention is made up of the composition of following weight part: papoid 1-600 part, bromeline 0-500 part, edible sodium bicarbonate 1-300 part, wherein papoid raw material activity is 20-300 ten thousand ultraviolet units/gram, and bromeline raw material activity is a 20-60 woman's bow woods units/gram.

Enzyme clean-out system of the present invention preferentially selects for use the composition of following weight part to form: papoid 300-500 part, bromeline 200-400 part, edible sodium bicarbonate 70-130 part.

Enzyme clean-out system of the present invention is to take by weighing papoid, bromeline and edible sodium bicarbonate in proportion respectively, makes tablet or pulvis or aqua after the raw material that takes by weighing is mixed.

During concrete the use, can select for use the per kilogram fruit and vegetable to add clear water 1000-3000ml, enzyme-added clean-out system tablet or pulvis 2-6 gram soaked 5-15 minute, washed down with clear water and can eat usefulness.

Below in conjunction with embodiment the present invention is described in further detail.

Embodiment 1:

Taking by weighing commercially available activity is bromeline 300 grams of 30 woman's bow woods units/gram, and activity is papoid 400 grams of 2,000,000 ultraviolet units/gram, edible sodium bicarbonate 100 grams.Above-mentioned mixing of materials is stirred in stirrer, be pressed into the tablet of every 1 gram again with common tablet machine.

According to the method for embodiment 1, the component that takes by weighing following different deals is made the tablet of different activities dosage.

According to the given component of the foregoing description, directly mix and be enzyme clean-out system pulvis of the present invention; Be dissolved in water after the component that the foregoing description is given is mixed and be zymin aqua of the present invention, institute's amount of water is unrestricted.

Claims

1, a kind of method of removing pesticide residue on picked melon and fruit, it is characterized in that adopting by activity is 20-300 ten thousand ultraviolet units/gram papoid 1-600 weight parts, activity is a 20-60 woman's bow woods units/gram bromeline 0-500 weight part, the clean-out system that edible sodium bicarbonate 1-300 weight part is formed is thrown in the clear water and was soaked fruit and vegetable 5-15 minute, washes down with clear water again.

2, in accordance with the method for claim 1, it is characterized in that per kilogram fruit and vegetable clear water 1000-3000ml, clean-out system 2-6 restrains immersion.
