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] Embodiment 1: Improve the comparative example of spray-drying hot-melt type sticky wall of hawthorn extract

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

[0019] Hawthorn is properly extracted and concentrated to obtain an extract (solid content of 20%), which is divided into two equal parts, one of which is added with soybean peptide powder (model: soybean protein isolate, manufacturer: Shansong Biological Products Co., Ltd.), which accounts for 30% of the dry paste of the extract. Company, in line with the first-class standard of physical and chemical indicators of soybean peptide powder in GB / T 22492-2008), stir to make the dispersion uniform, and spray dry under stirring conditions (BUCHI-B290 spray dryer, the process parameters are set as: inlet air temperature 140℃, atomization pre...

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

[0021] Jujube is a food with the same origin of medicine and food, and its water extract has serious hot-melt type sticking during the spray-drying process.

[0022] The jujube is properly extracted to obtain the extract, the solid content is adjusted to 2%, and the extract is divided into four parts on average. According to Table 1, add the corresponding auxiliary materials respectively (the addition amount of magnesium oxide is 5% of the dry paste of the extract, the addition amount of HPMC F5 is 15%, and the addition amount of pea peptide powder is 15%) and stir to make the dispersion uniform, and under stirring conditions spray drying (BUCHI-B290 spray dryer, the process parameters are set as: inlet air temperature 140°C, atomization pressure 1.05bar, liquid inlet velocity 9mL / min, inlet air volume 35m 3 / h). Pure jujube water extract and magnesium oxide-add...

Embodiment 3

[0025] Example 3: Improve the spray-drying hot-melt type sticky wall of Qiangli Ning extract

[0026] Qiangli Ningfang is a variety collected in the 10th volume of the "Medical Standard Chinese Medicine Formulations of the Ministry of Health". In the experiment, it was found that the hot-melt type sticking of the extract occurred during spray drying.

[0027]The difference in properties of the products obtained by comparing the method of patent ZL201010298981.4 and the method of this patent: Qiangli Ningfang is properly extracted and concentrated to obtain Qiangli Ningfang extract (solid content: 10%); it is divided into 3 parts on average, the first part is directly spray-dried, and the second part is directly spray-dried. Two parts were added with HPMC E3 which accounted for 20% of the solid content of the extract, and the third part was added with rice peptide powder which accounted for 20% of the solid content of the extract (Model: Rice Peptide Powder, Manufacturer: China...

Abstract

The present invention is a method for improving the spray-drying hot-melt type sticky wall of traditional Chinese medicine or food raw materials, comprising the following steps: adding any one or more than one small molecule peptides to the solution to be dried with a solid content of 2-50% as The auxiliary materials are added in an amount of 5-30% of the solid content of the solution to be dried, which is uniformly dispersed by stirring and spray-dried under stirring conditions. The auxiliary material of the invention is safe, does not interfere with the release of the main components of the medicine, has a wide range of application, and has good solubility of the obtained product, which can effectively improve the problem of hot-melt type sticking to the wall in the spray drying process. The present invention also provides the application of the small molecule peptide in improving the spray-drying hot-melt type sticky wall of traditional Chinese medicine or food raw materials.

Description

technical field [0001] The invention belongs to the technical field of drying technology, and in particular relates to a method for improving the spray-drying hot-melt type sticky wall of traditional Chinese medicine or food raw materials by using auxiliary materials; in particular, it relates to a plant-derived natural small molecule peptide for improving the spray-drying hot-melt type sticky wall of traditional Chinese medicine or food raw materials. wall method. 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 "instant drying", "good quality of dried products" and "simple drying process". However, due to the nature of the material itself, the hot-melt type sticking phenomenon often occurs in the spray drying process. The main phenomenon is that there are droplet-like agglomeration on the inner wall of the spray dryer, which is firmly combined with the i...
