Problems solved by technology

[0006] patent application CN200710032129.0 discloses a deodorant with pomelo peel as the main raw material and a preparation method thereof, but what the method uses is the whole grapefruit peel as raw material. Remove the outer yellow skin (also known as the oil bubble layer) of the pomelo peel and process it directly. In this way, there will be the following problems: the oil bubble layer is relatively dense, basically has no adsorption capacity, and will hinder the adsorption performance of other parts of the material; It is easy to produce peculiar smell and miscellaneous smell during processing and storage, which will affect the quality of the final product; the oil bubble layer shrinks after drying and the color is easily browned, and the appearance of the product is not good; the oil bubble layer is the characteristic aroma of grapefruit---the only part where grapefruit essential oil exists , and is rich in functional ingredients such as naringin, directly using it as an adsorbent is also a waste of resources
In this patent, the raw material of pomelo peel has not been treated with enzyme deactivation and sterilization, which will cause problems in the application of the product. When the product absorbs a certain amount of odor and moisture, the pectin hydrolysis of pomelo peel will easily occur. , mildew and other phenomena, affecting the use of the product

Embodiment 1

[0023] Use a pomelo peeler to first peel off the oil bubble layer of the pomelo peel in Shatian grapefruit, and then cut off the remaining part of the pomelo peel to obtain a white, spongy pomelo sac; the pomelo sac is scalded with alkaline water, and the process conditions are: NaOH solution concentration 30%, the weight ratio of pomelo skin and solution is 1:5, the treatment temperature is 60°C, the treatment time is 3h, scald with alkaline water (the process is: the concentration of NaOH solution is 10%, the weight ratio of grapefruit skin and NaOH solution is 1:4 , the treatment temperature is 60°C, the treatment time is 2), and then washed with water until neutral, then centrifuged at 3000 rpm for 10 minutes to remove most of the water, then dried at 80°C until the water content is less than 10%, and crushed to particle size The size is 300-500 μm, weighed and packaged to obtain the plant-type adsorption material 1.

Embodiment 2

[0025] Use a pomelo peeler to first peel off the oil bubble layer of the honey pomelo pomelo peel, and then cut off the remaining part of the pomelo peel to obtain a white, spongy pomelo sac; the pomelo sac is scalded with alkaline water, and the process conditions are: NaOH solution concentration 20%, the weight ratio of pomelo peel and solution is 1:4, the treatment temperature is 80°C, and the treatment time is 3h. : 8, the treatment temperature is 90°C, and the treatment time is 4h) and then washed with water until neutral, then centrifuged at 4000 rpm for 5 minutes to remove most of the water, then dried at 70°C until the water content is less than 12%, and crushed to granules The diameter is 500~800μm, evenly spray preservative sodium benzoate (the dosage is 2‰ of the dry weight of pomelo sac granules) and rose essence (the dosage is 0.1‰ of the dry weight of pomelo sac granules), weigh and pack to obtain plant-type adsorption Material 2.

Embodiment 3

[0027] Use a pomelo peeler to first peel off the oil bubble layer of the pomelo pomelo peel, and then cut off the remaining part of the pomelo peel to obtain a white, spongy pomelo sac; the pomelo sac is scalded with alkaline water, and the process conditions are: NaOH solution concentration 10%, the weight ratio of pomelo skin and solution is 1:8, the treatment temperature is 70°C, the treatment time is 4h, scalding with alkaline water (the process conditions are: the concentration of NaOH solution is 20%, the weight ratio of grapefruit skin and NaOH solution is 1: 6. The treatment temperature is 70°C, the treatment time is 3h), and then washed with water until neutral, then centrifuged at 3000 rpm for 10 minutes to remove most of the water, then dried at 80°C until the water content is less than 8%, and crushed to granules The diameter is 400-600 μm, and the preservative potassium sorbate is evenly sprayed (the dosage is 2‰ of the dry weight of pomelo sac particles), weighed ...

Abstract

The invention discloses a botanic adsorption material and application thereof. The botanic adsorption material is prepared by the steps of performing enzyme inactivation on capsules of pomelo peels, sterilizing and processing, has a porous structure, can effectively remove peculiar smell and harmful gas, and can be applied to the fields of indoor air purification, automobile deodorization and the like. The technology for processing the adsorption material is simple, high in biocompatibility and biodegradability, excellent in usability, broad in application range, and high in added value; and moreover, a byproduct, namely the pomelo peels generated in the deep processing of pomelos can be quickly and massively utilized, so that the technical level and economic benefit of the pomelo processing industry are promoted.

Description

technical field [0001] The invention relates to the deep processing technology of pomelo, in particular to a plant-type adsorption material with good adsorption performance, wide application range and high added value, which is processed by the by-product pomelo peel in the deep processing of pomelo. Background technique [0002] Grapefruit (Citrus grandis), also known as Wendan, is a citrus fruit of Rutaceae, including Shatian pomelo, honey pomelo, Hu pomelo, Wendan pomelo, and Pingshan pomelo. It is native to China, India, and Malaysia, and is grown in Zhejiang, Fujian, Guangdong, and Guangxi along the coast of my country. Grapefruit pulp is sweet and delicious, and has high nutritional and medicinal value. According to the determination, pomelo fruit not only contains a variety of nutrients necessary for human health, such as various amino acids, thiamine, riboflavin, ascorbic acid, niacin, calcium, iron, phosphorus, etc., but also contains a variety of nutrients that ar...
