Problems solved by technology

However, due to the consideration of taste, most people add a large amount of coffee mate when drinking coffee, often adding sugar, animal oil lipids or whole milk. The long-term intake of the above-mentioned high-calorie materials will cause the failure of weight loss.
Some slimming coffee also contains a certain amount of laxatives, which can also cause certain damage or drug resistance to the gastrointestinal tract. For people with potential colitis, drinking this type of coffee will also cause certain damage to the intestinal tract

Embodiment 1

[0024] Embodiment 1: the rheological characteristic determination of duck oil diglyceride

[0025] (1) Preparation of diglycerides: put glycerol and duck oil mixed fatty acids in a conical flask at a ratio of 1:0.5 to 3, add 0.5% to 3% of immobilized Candida antarctica lipase B, and then Place it on a shaker, set the temperature at 30°C to 70°C, and set the reaction time at 2 to 12 hours. After the reaction, centrifuge the above reaction solution in a high-speed centrifuge at 4000r / min for 20 minutes to completely separate the enzyme. The obtained supernatant is a high-purity diglyceride mixture.

[0026] Pour duck oil, soybean oil, duck oil diglyceride, and lard into a beaker, and use a rheometer to detect, shear rate: 2.509-100 / s, temperature 25°C.

[0027] by manual figure 1 It can be seen that there is no significant difference in the shear stress of duck oil, soybean oil, and duck oil diglyceride, while the shear stress of lard is significantly increased compared with t...

Embodiment 2

[0028] Example 2: Response Surface Optimization Optimum Conditions for the Ratio of Instant Coffee Powder for Fat-lowering Health Care

[0029] Response surface design was carried out based on the results of single factor experiments, and the principle of Box-Behnken central combination design was applied. The three factors of single factor diglyceride added amount, konjac added amount and xylitol added amount were used as independent variables, represented by A, B, and C respectively, and -1, 0, 1 respectively represented the low, medium, and High-level coding is carried out, and the experiment is designed with dispersibility, brewability, and hygroscopicity as the response values. The level design of the experimental factors is shown in Table 1, and the results are shown in Table 2.

Embodiment 3

[0058] Embodiment 3: the preparation of fat-reducing health-care instant coffee powder

[0059] (1) Combination of raw materials for lipid-lowering health-care instant coffee: add 1.5% to 2.5% diglyceride, 3% to 9% konjac powder and 1% to 3% xylitol respectively, and stir homogeneously.

[0060] (2) Preparation of fat-reducing health-care instant coffee powder: place the above-prepared mixture at -20°C for 48 hours, and then vacuum freeze-dry the conditions: -54°C, 10 Pa, freeze-drying time is 48 hours, take it out and grind it Instant coffee powder for lipid-lowering health care.

Abstract

The invention aims to provide fragrant lipid-lowering health-care instant coffee powder. The fragrant lipid-lowering health-care instant coffee powder comprises duck oil diglyceride, konjaku flour, xylitol and coffee powder, wherein the mass ratio of the coffee powder to the duck oil diglyceride to the konjaku flour to the xylitol is 1:(0.01-0.05):(0.03-0.09):(0.01-0.03). The duck oil diglycerideis prepared by mixing duck oil mixed fatty acid with glycerol, adding immobilized lipase to react, and separating the lipase from a substrate after the reaction. The xylitol and the konjaku flour areadded into the coffee powder prepared by the invention, so that brewed coffee is better in taste, has the health-care effects of reducing lipid, cholesterol and blood sugar, and is beneficial to digestion and reduction of digestive tract diseases. The two natural auxiliary materials are matched, so that no irritation or toxic and side effects are caused to the intestinal tract.

Description

technical field [0001] The invention belongs to the technical development field of functional food, and in particular relates to a preparation method of fragrant-type lipid-lowering health-care instant coffee powder. Background technique [0002] Obesity, a chronic metabolic disease, has become a global epidemic. In addition to a fast-paced lifestyle, the intake of oily and delicious food and a sedentary work style are the main reasons for the increase in obesity rates. Obesity can lead to many other complications as well. Coffee contains a lot of caffeine, which can increase the basal metabolic rate and thus have the effect of reducing fat and losing weight. However, due to the consideration of taste, most people add a large amount of coffee mate when drinking coffee, often adding sugar, animal oil lipids or whole milk. The long-term intake of the above-mentioned high-calorie materials will cause the failure of weight loss. Some slimming coffee also contains a certain am...
