Embodiment 1
[0034] Embodiment 1. A kind of cistanche instant coffee and preparation method thereof
[0035] (1) Preparation of Cistanche deserticola extract: remove surface sediment from Cistanche deserticola, wash and drain, cut into small pieces, dry in a constant temperature blast drying oven at 60°C for 12 hours, take out after drying and crush through a 40-mesh sieve with a pulverizer Prepare the desert Cistanche dry powder for later use; weigh 100g of the desert Cistanche dry powder to be used, put it in a 3000mL eggplant-shaped flask, add 1600mL of water, condense and reflux at 100°C for extraction for 3 times, filter to remove the desert Cistanche residue, and combine the three extracts , and then concentrate under reduced pressure, the concentration conditions are set at a speed of 100-130r / min, the temperature of the water bath is 60°C, the initial pressure of the vacuum pump is above 0.08MPa, and the concentration is concentrated to a relative density of 1.2 to obtain the desert...
Embodiment 2
[0041] Embodiment 2.D- optimal mixture design optimizes the method for Cistanche instant coffee
[0042] (1) Using D-optimal mixture design, the total ratio of the total powder (the sum of skimmed milk powder and non-dairy creamer) (A), the amount of sugar added (B), and the total powder (C) is 3 mixing factors: 100%, with the ratio of meat to coffee (mass ratio of the two extracts of Cistanche deserticola and coffee bean extract) (D) as a continuous factor, 18 groups of experiments that have been carried out by the preparation method of Example 1 are used to investigate each group The influence of portion proportion on sensory score, and get the final score of each experimental group, the sensory score method is as follows: figure 1 shown;
[0043] According to the subjective weighting method, this experiment sets the weight of three indicators, X 外在表现 、X口感复杂度 、X 基础味道 The order is 0.3, 0.4, 0.3, so the weight set of cistanche coffee is X={0.3,0.4,0.3}.
[0044] Score each...
