Primary processing method for loofah sponge

Abstract

The invention provides a primary processing method for loofah sponge. The primary processing method for the loofah sponge comprises the steps of (1) peeling: immersing the whole loofah into 8 to 12 percent of strong-base water solution, and soaking at 70 to 90 DEG C until the loofah peels are softened and rotted; (2) flushing: removing the loofah peels of the loofah obtained in the step (1), flushing through water for 2 to 3 times, and obtaining loofah sponge to be treated; (3) decoloring: immersing the whole loofah sponge to be treated obtained in the step (2) into 5 to 10 percent of bleaching agent water solution, soaking until the green color is fully removed, and obtaining bleached loofah sponge; (4) flushing: flushing the bleached loofah sponge obtained through the step (3) through water for 2 to 3 times, and obtaining flushed loofah sponge; (5) whitening: immersing the flushed loofah sponge obtained in the step (4) into 3 to 5 percent of softener water solution with a whitening function, and soaking until the flushed loofah sponge becomes white; and (6) drying: drying in the air, and removing loofah seeds. The primary processing method is short in processing time, and the product is uniformly white in color and is not easy to yellow.

Description

Technical field [0001] The invention belongs to the field of industrial material manufacturing, and particularly relates to a method for initial processing of loofah. Background technique [0002] Luffa cylindrical Roem (Luffa Cylindrical Roem.), also known as Tianluogua, Tianluogua, Mangua, Tianluo, cotton gourd and cloth gourd, is an annual climbing herb in the squash family. As a new economic crop, loofah is widely grown in tropical and subtropical regions at home and abroad. Loofah is native to India, and it was introduced to our country around the end of the Tang Dynasty and the beginning of the Song Dynasty. It can be used as a vegetable, as a medicine, or used as daily necessities and engineering materials. Because of its high yield, good quality and wide application, loofah is widely grown in various parts of the north and south of my country. At present, the flesh of the loofah in our country is often eaten when it is immature, and the silk is used after it is mature. ...

AI Technical Summary

Problems solved by technology

[0005] (1) The product quality is poor

Loofah is prone to corruption and deterioration in long-term soaking, and the color turns yellow, resulting in problems such as poor color and low quality of the product;

[0006] (2) The processing cycle is too long

[0007] (3) The green pigment in the loofah pulp is not easy to remove

The maturing season of loofah is mostly in the rainy autumn season. Because it cannot be harvested in time, loofah is easy to over-ripen, causing the green pigment in the green skin of loofah to easily enter into loofah. It is difficult to remove the green color of loofah by traditional preparation methods.
