Radix pseudostellariae ultrafine powder yogurt and preparation method thereof

Abstract

The present invention discloses radix pseudostellariae ultrafine powder yoghurt and a preparation method thereof. The radix pseudostellariae ultrafine powder yoghurt is prepared from raw material milkas a base material. The radix pseudostellariae ultrafine powder yoghurt is prepared from the following components based on the weight percentages of the liquid-state raw material milk: 0.01%-0.5% ofradix pseudostellariae powder, 1%-10% of sucrose, 0-0.5% of a thickener, 0.001%-0.01% of a fermentation agent, 0-10% of prebiotics and 0-0.05% of a sweetener. The preparation method comprises the following steps: radix pseudostellariae is selected; the selected radix pseudostellariae is dried; the dried radix pseudostellariae is crushed; the crushed radix pseudostellariae passes a sieve mesh; thesieved radix pseudostellariae is subjected to superfine crushing to obtain radix pseudostellariae ultrafine powder; the raw milk is used at the base material; the radix pseudostellariae untrafine powder, sucrose, thickener, sweetener and prebiotics are added; the materials are mixed in vacuum; the mixture is homogenized at 30 MPa and a temperature condition of 50 DEG C-60 DEG C for 10 min-20 min;the materials are stirred and heated to 80 DEG C-90 DEG C; the heated materials are sterilized for 5 min-20 min; the sterilized materials are cooled; the fermentation agent is added; and the materialsare fermented at a condition of 40 DEG C-43 DEG C for 4 h-5.5 h to obtain the radix pseudostellariae ultrafine powder yoghurt. The radix pseudostellariae ultrafine powder yoghurt is reasonable in nutrient matching and simple and easy to implement in processing method; the effective ingredients of the radix pseudostellariae are fully utilized; the radix pseudostellariae has the health-benefiting effect; and every gram of the radix pseudostellariae ultrafine powder yoghurt contains more than 7x10<8> lactic acid bacteria.

Description

technical field [0001] The invention relates to the technical field of functional food processing, in particular to superfine powdered yoghurt with heterophylla and a preparation method thereof. Background technique [0002] Pseudostellaria heterophylla is the dry root tuber of Pseudostellaria heterophylla (Miq.) Pax ex Paxet Hoffm. It has the effects of replenishing qi and invigorating the spleen, promoting body fluid and moistening the lungs. It is often used for spleen deficiency, fatigue, loss of appetite, weakness after illness, deficiency of qi and yin, spontaneous sweating, daily thirst, dryness of lung and dry cough. [0003] Natural plant raw materials, through pulverization, especially superfine pulverization, the particle size is significantly reduced, and the specific surface area is significantly increased, making the product highly dispersible and highly soluble. Crushing raw materials into superfine powder is helpful for the extraction of active ingredients ...
