Embodiment 1

[0012] A method for extending the storage time of rice, comprising the following steps:

[0013] The rice obtained by shelling is placed in a dry container, and the prepared rice storage agent is wrapped with air-permeable gauze, and each wrapped gauze bag weighs 18 grams, and the gauze bag is placed in the container of rice. Place one evenly, store it away from light at a temperature of 15°C and a relative air humidity of 50%, keep it well ventilated, and turn it every 25 days.

[0014] The preparation method of the rice storage agent is as follows: take 88 grams of calcium-based bentonite and pulverize it to 80 mesh, add 4.0 times the volume of zinc chloride solution with a molar concentration of 0.15 mol / liter, stir and mix evenly, add 0.5 gram of dodecyl Sodium sulfate, continue to stir for 30 minutes to obtain a homogeneous mixture, place it in an oven at 80°C for aging for 14 hours, and filter it after naturally cooling to 20°C. The obtained filter is soaked in the cocon...

Embodiment 2

[0017] A method for extending the storage time of rice, comprising the following steps:

[0018] The rice obtained by shelling is placed in a dry container, and the prepared rice storage agent is wrapped with air-permeable gauze. Each wrapped gauze bag weighs 19 grams. Place one evenly, and store it away from light at a temperature of 20°C and a relative air humidity of 60%, keep it well ventilated, and turn it every 28 days.

[0019] The preparation method of the rice storage agent is as follows: Weigh 89 grams of calcium-based bentonite and pulverize it to 90 meshes, add 4.1 times the volume of zinc chloride solution with a molar concentration of 0.18 mol / liter, stir and mix evenly, add 0.8 grams of dodecyl Sodium sulfate, continue to stir for 32 minutes to obtain a homogeneous mixture, place it in an oven at 85°C for 15 hours, and filter it after naturally cooling to 22°C. The obtained filter is soaked in coconut shell extract for 100 minutes. : 1.35, soaking temperature i...

Embodiment 3

[0022] A method for extending the storage time of rice, comprising the following steps:

[0023] The rice obtained by shelling is placed in a dry container, and the prepared rice storage agent is wrapped with air-permeable gauze, and each wrapped gauze bag weighs 20 grams, and the gauze bag is placed in the container of rice. Place 2 evenly, and store them away from light at a temperature of 25°C and a relative air humidity of 70%, keep them well ventilated, and flip them every 30 days.

[0024] The preparation method of the rice storage agent is as follows: take 90 grams of calcium-based bentonite and pulverize it to 100 mesh, add 4.2 times the volume of zinc chloride solution with a molar concentration of 0.20 moles / liter, stir and mix evenly, add 1.0 grams of dodecyl Sodium sulfate, continue to stir for 35 minutes to obtain a homogeneous mixture, put it in a 90°C oven for aging for 16 hours, and filter it after naturally cooling to 25°C. The obtained filter is soaked in coc...

Abstract

The invention relates to the technical field of modern agriculture industry and discloses a method for prolonging storage time of rice. According to the method, due to a rice storage mode, the aim ofprolonging the storage time of the rice can be prolonged through inhibiting autologous vital activity of the rice and molds of the surface of the rice and preventing worm eating, problems such as foodsecurity and environmental pollution cannot be caused, and the requirements of people on sufficiently protecting and utilizing food resources are met. According to the method, problems present in theexisting rice storage are effectively solved, the shelf life is prolonged remarkably, a deterioration phenomenon is still absent after storage in 8-10 months, the stored rice has the characteristicsthat the nutrition and taste are not affected, protein and starch structures cannot be changed, and the nutritive value is guaranteed; and the method is an energy-efficient storage method, the balancebetween the productivity and supply of paddy rice is achieved, and the durable development of foodstuff industry is facilitated.

Description

technical field [0001] The invention belongs to the technical field of modern agricultural industry, and in particular relates to a method for prolonging the storage time of rice. Background technique [0002] Rice is the finished product of rice after cleaning, husking, rice milling, finishing and other processes. Rice contains nearly 64% of the nutrients in rice and more than 90% of the nutrients needed by the human body. It is also the most important food in China. The main food of the people of the region. According to reports, the grain loss caused by rice mildew and insect infestation in our country is as high as tens of millions of tons every year, and the economic loss is huge. Paddy is susceptible to mold and insect pests during the planting period. Although most of the attachments are removed with shelling during the processing process, other molds are still prone to be produced due to the large-scale reproduction of insects, rats, and molds during storage. and i...
