Description

A kind of cut flower preservation tablet and preparation method thereof

technical field

The invention relates to the technical field of fresh-keeping agents for cut flowers, in particular to a fresh-keeping tablet for cut flowers and a preparation method thereof.

Background technique

Tablets refer to the dosage forms in which medicines are processed into tablets. This dosage form is one of the most commonly used pharmaceutical dosage forms today. Compressing medicine into tablets was invented by the British Brockton in 1843, and has a history of more than 100 years so far. Tablets are one of the most widely used dosage forms in modern pharmaceutical preparations, and their production technology and mechanical equipment updates are developing rapidly. However, in terms of tableting technology, the gap between the tableting machine and tableting technology between my country and developed countries is still widening. High-speed, high-yield, airtight, modular, large-scale and advanced testing technology are the most important aspects of foreign tableting machine technology. Direction of development.

At present, the tablet preparation processes mainly include wet granulation, dry granulation, powder direct compression, and freeze-drying. About 40% of the varieties in foreign countries adopt the powder direct compression method. The main advantages of this process are energy saving, time saving, and faster disintegration or dissolution of the product. It is mainly suitable for compounds that are unstable due to humidity and heat, and has high requirements for drugs and excipients. Excipients are required to have good fluidity and compressibility, and the particle size and crystal form of the drug meet the requirements of tablet compression. At present, the powder direct compression method is seldom used in domestic production, mainly due to the limitation of auxiliary materials, technological level and equipment. At present, the excipients used in powder direct compression mainly include microcrystalline cellulose, lactose, mannitol, calcium hydrogen phosphate dihydrate, sucrose, starch, chitosan, pregelatinized starch, crospovidone, micronized silica gel, etc. Lubricants are mostly micronized silica gel, magnesium stearate and stearic acid.

The process of powder direct compression method is relatively simple, and it has high requirements for auxiliary materials and equipment. The equipment generally uses fortified feed to reduce the difference in tablet weight. However, for low-dose varieties, the content uniformity is difficult to control. The general method of controlling the content uniformity is to mix the main drug with the disintegrant and glidant according to the method of equal increase, then pulverize and mix with an appropriate amount of filler with a ball mill, and then mix with the rest of the excipients. The direct compression process is developed with the development of excipients.

Fresh cut flowers are one of the important product types of flower industrialization production. From a global perspective, its output value accounts for 80% of the total output value of flowers. After the flowers are picked and leave the mother body, they will wither quickly without the supply of nutrients, thus losing their ornamental value. Therefore, fresh cut flowers must be kept fresh. The preservation effect of cut flowers is directly related to the ornamental value and economic value of fresh cut flowers. The external factors affecting the preservation of cut flowers mainly include temperature, light, air humidity, mechanical damage, etc.; the internal factors include water metabolism imbalance, microbial infection, increased cell membrane permeability, increased respiration rate, lack of nutrition, and changes in endogenous hormones.

In response to these factors, commonly used fresh-keeping techniques include physical fresh-keeping and chemical fresh-keeping. Chemical preservation is commonly referred to as the use of preservatives for preservation. As early as 1949, Belgian biochemist Boes added chemicals to water and found that the life span of cut flowers could be significantly extended. Commonly used fresh-keeping agents for cut flowers include fungicides, ethylene inhibitors and antagonists, plant growth regulators, nutrients and water supplements, pH regulators, etc.

China's flower industry started relatively late, and there are still many problems and difficulties in the research of fresh-cut flower preservation technology. There are many research reports on fresh-cut flower preservation technology, but there is a lack of broad-spectrum and high-efficiency cut flower preservatives. Research reports mostly give preservative formulations (CN 200910227591.5; CN 201010293177.7; CN 201110023036.8), which contain a lot of medicines, which is extremely inconvenient for users to use; even if some preservative formulations are processed into water formulations for users to use (CN101002552A) , but storage and transportation are extremely inconvenient.
