Abstract
The invention discloses a comprehensive utilization method of banana stems and leaves and relates to the comprehensive utilization of plant stems and leaves. The method comprises the following steps: 1) cleaning the banana stems and leaves, purifying the cleaning sewage, and recycling the purified water; and taking out the filtered precipitate and drying to obtain a raw material of a bio-fertilizer; 2) squeezing the cleaned banana stems and leaves, separating the stem-leaf residue from the juice, and sealing the separated juice; 3) melting the separated stem-leaf residue; 4) performing residue-juice separation of the molten stem-leaf residue, and sealing the separated juice; 5) filtering the juice obtained in the steps 2) and 4) and sterilizing in a high-temperature pressure tank; mixing the sterilized juice with the biological raw material, and fermenting in a sealing tank; and adding a stabilizer and further fermenting to obtain a biological agent; and 6) directly adopting the stem-leaf residue after juice extraction as a raw material of papermaking fiber, or bleaching with an oxidizing agent to obtain a raw material of weaving fiber, or smashing to obtain a feed and an additive thereof.
Description
Technical field
The present invention relates to a kind of comprehensive utilization of plant stem-leaf, particularly relate to the method for comprehensive utilization of banana stem leaves.
Background technology
Southern china and the torrid zone such as Taiwan and Southeast Asia, India, Africa and warm torrid areas are all main places of production of banana.According to incompletely statistics, annual global banana planting area is more than 3,000 ten thousand mu, and total output is more than 400,000,000 tons, and wherein China (containing Taiwan) accounts for 20%.Banana is one of world's " four large fruit ", very popular.
After annual banana is gathered, banana stem leaves just becomes discarded object, and the weight of its cauline leaf is about 2 ~ 4 times of fruit (15 ~ 30kg/).Visible, the substantial amounts of banana stem leaves, various pollutions such as the soil environment, river and the underground water that cause after discarded and grow insect pest, harmful effect is extremely serious.These problems have caused global great attention, and take certain measure and alleviated; How better turning waste into wealth, comprehensive exploitation and effectively utilize the cauline leaf of banana, improves its economic worth, receives much concern always.
Banana is except fruits nutrition is abundant, and its cauline leaf is also " treasured ".First be the juice of banana stem leaves except large quantity of moisture, also containing amino acid, vitamin and Activities of Some Plants albumen, tannin (also known as tannic acid or tannin) rich content wherein, accounts for 1% ~ 3% of juice total amount.Tannin belongs to the active ingredient of water-soluble polyphenols class material, is natural organic compound.Show through inquiry Research Literature, tannin active component is considered to have convergence and protein coagulating effect at field of medicaments, can be used for hemostasis, antidiarrheal, sterilizing and antiviral etc. clinically; Current research also finds that it has the multiple pharmacologically actives such as anti-sudden change, anti peroxidation of lipid, scavenging free radicals, antitumor and anti-AIDS, also has certain sterilizing pesticide evil effect.Visible, the juice of banana stem leaves has tempting application prospect.
In the cauline leaf of banana, except about 90% is except water and tannin composition etc., all the other about 10% are strings, can as papermaking, weave cotton cloth, fibrous raw material and the organic fertilizer such as feed, its economic worth is considerable.
