Far infrared insect prevention rice packing material made of loess and preparation method thereof

Abstract

The invention disclose a preparation method for a healthy and environment-friendly rice packing material which can prevent insects and corrosion and can keep moisture and the original mouthfeel and fragrance of rice, and the rice packing material prepared by the method. The method comprises the following steps of: mixing and stirring 10 to 29 mass percent of loess, 20 to 39 mass percent of edible corn starch, 1 to 10 percent of illite or bamboo charcoal, and 50 to 69 mass percent of water, and heating to 100 to 120 DEGC and boiling for 10 to 20 minutes to obtain loess mixed liquid; and coating 1 to 10g of loess mixed liquid on each square meter of one side of body paper by using a coating device, coating sizing liquid on the other side of the body paper, squeezing a layer of plastic fiber compound paper on the sizing liquid, and drying to obtain the rice packing material. A rice packing bag made of the packing material has enough intensity and can keep the moisture of the rice; and even if the rice is stored for a long time, after the rice is cooked into steamed rice, the fragrance and mouthfeel of the original rice can be kept.

Description

technical field [0001] The invention relates to a rice packaging material and a production method thereof, in particular to a far-infrared insect-proof rice packaging material made of loess and a production method thereof. Background technique [0002] At present, ordinary plastic woven bags are mostly used as packaging products in China. In order to prevent rice leakage, the outer surface of ordinary plastic woven bags is also coated with a layer of polyethylene or polypropylene coating film. Although this type of woven bag has sufficient strength and the rice does not leak, it does not have insecticidal and sterilizing properties, which reduces the shelf life of the rice. In order to kill insects, in the early 1990s, a kind of polymer film structure packaging bag with a layer of insecticide coated on the outer surface of an ordinary plastic woven bag appeared in China, and the insecticide in the film was slowly released to form an insecticide. To prevent insects and kill ...

Although this type of woven bag has sufficient strength and rice does not leak, it does not have insecticidal and sterilizing properties, which reduces the shelf life of rice

In order to kill insects, in the early 1990s, a kind of polymer film structure packaging bag with a layer of insecticide coated on the outer surface of an ordinary plastic woven bag appeared in China, and the insecticide in the film was slowly released to form an insecticide. To prevent insects and kill insects, although the coating can kill insects, it still cannot inhibit the growth and elimination of grain molds, and chemical pesticides bring great danger to eaters

This kind of rice bag is not only still unfavorable for the preservation of grain, but also endangers the health of eaters.

In recent years, an inner plastic bag made of polyethylene, surface roughening agent and insect-proof and mildew-proof agent raw materials has come out. The bag is equipped in an outer woven bag to hold grain. ingredients, and the production process is complex and costly, so there is no fundamental solution to the conflict between the quality assurance of rice and the threat to the health of eaters
