Problems solved by technology

However, the auxiliary materials used in this method have a certain viscosity, and if the water reconstitution speed of the dry product is required to be high, there is no advantage
In addition, the spray-drying process parameters of this method have a small application window, which requires precise optimization of process parameters and high requirements for instrument and equipment control
Once the process parameters are not suitable, there will be a risk of incomplete drying or hot-melt sticky walls again

Embodiment 1

[0017] Example 1: Comparative Example of Improving Hawthorn Extract Spray Drying Hot-melt Type Adhesive Wall

[0018] Hawthorn belongs to the food with the same origin of medicine and food. Its water extract is often used alone or added to other medicines or foods, but the spray drying process of its extract has serious hot-melt sticky walls.

[0019] Hawthorn is properly extracted and concentrated to obtain the extract (solid content 20%), which is divided into two parts on average, one of which is added with soybean peptide powder (model: soybean protein isolate, manufacturer: Shansong Biological Products Co., Ltd. company, in line with the first-class standard of physical and chemical indicators of soybean peptide powder in GB / T 22492-2008), stirring to make the dispersion uniform, and spray drying under stirring conditions (BUCHI-B290 spray drying instrument, the process parameters are set as: inlet air temperature 140℃, atomization pressure 1.05bar, liquid inlet speed 9mL...

[0020] Embodiment 2: Improve jujube extract spray drying hot-melt type sticky wall comparative example

[0021] Jujube belongs to the food with the same origin of medicine and food, and its water extract has serious hot-melt sticky wall during spray drying.

[0022] The jujube is properly extracted to obtain an extract, the solid content is adjusted to 2%, and the extract is divided into four parts on average. According to Table 1, add corresponding adjuvants respectively (magnesium oxide addition is 5% of the dry paste amount of extract, HPMC F5 addition is 15%, pea peptide powder addition is 15%) and stir to disperse evenly, and under stirring conditions Spray drying was carried out under the following conditions (BUCHI-B290 spray dryer, the process parameters were set as: air inlet temperature 140°C, atomization pressure 1.05bar, liquid inlet speed 9mL / min, air inlet volume 35m 3 / h). The pure jujube water extract and the extract added with magnesium oxide can not be spra...

[0025] Example 3: Improving Qianglining extract spray drying hot melt type sticky wall

[0026] Qianglining Fang is a variety recorded in Volume 10 of "Ministry of Health's Pharmaceutical Standards for Traditional Chinese Medicine Prescriptions". In the experiment, it was found that the extract was hot-melt and sticky to the wall when it was spray-dried.

[0027]Comparing the difference in properties between the patent ZL201010298981.4 method and the product obtained by this patent method: Qiangli Ning Fang extract solution (solid content: 10%) was obtained through proper extraction and concentration of Qiangli Ning Fang; it was divided into 3 parts on average, the first part was directly spray-dried, and the second part was directly sprayed and dried. Two parts were added with HPMC E3 accounting for 20% of the solid content of the extract, and the third part was added with rice peptide powder (model: rice peptide powder, manufacturer: Zhongshi Duqing (Shandong) Biotechnology ...

Abstract

The invention relates to a method for improving hot-melt wall adhesion of traditional Chinese medicines or food raw materials during spray drying. The method comprises the following steps: adding anyone or more small molecule peptides as auxiliary materials into a to-be-dried solution with the solid content of 2-50%, uniformly stirring and dispersing, and carrying out spray drying under a stirring condition, wherein the dosage of the added auxiliary materials is 5-30% of the solid content of the to-be-dried solution. The auxiliary materials are safe, the release of main components of the medicine is not interfered, the application range is wide, the obtained product is good in solubility, and the problem of hot-melt wall adhesion in the spray drying process can be effectively solved. Theinvention also provides application of the small molecule peptide in improving hot-melt wall adhesion of traditional Chinese medicines or food raw materials during spray drying.

Description

technical field [0001] The invention belongs to the technical field of drying technology, and in particular relates to a method for improving spray-dried hot-melt sticky walls of traditional Chinese medicine or food raw materials by using auxiliary materials; in particular, it relates to the use of plant-derived natural small molecule peptides for improving spray-dried hot-melt sticky walls of traditional Chinese medicine or food raw materials. way of the wall. Background technique [0002] Spray drying is a common drying method for traditional Chinese medicine extracts and food raw material solutions. It has the advantages of "instantaneous drying", "good quality of dried products", and "simple drying process". However, due to the nature of the material itself, hot-melt wall sticking often occurs during the spray drying process. The main phenomenon is that there are droplet-like agglomerates on the inner wall of the spray dryer, which are firmly combined with the inner wal...
