Embodiment Construction

[0012] The preparation method of arabica melaninoid pigment of the present invention, its concrete steps are as follows:

[0013] a. Roast Yunnan arabica green beans at 200°C or 250°C or 280°C for 10 minutes or 20 minutes or 30 minutes;

[0014] b. The roasted coffee beans are ground into powder and passed through a 100-mesh, 150-mesh or 200-mesh sieve;

[0015] c. According to coffee powder: water = 1:2-10 (m / v), add boiling pure, dissolve at 80°C or 85°C or 90°C for 10min or 20min or 30min, filter the coffee grounds, and collect the filtrate;

[0016] d. Take the filtrate according to coffee liquid: alcohol = 3: 7 (V / V) alcohol analysis for 12 hours or 18 hours or 24 hours, let it stand for precipitation, and centrifuge at 1000rpm / mi or 2000rpm / min or 2000rpm / min for 10min or 15min or 20min;

[0017] e. Use a freeze dryer at 0.4 mbar, freeze-dry at -55°C, and finally pulverize the dried product to obtain coffee-like black essence.

Abstract

The invention relates to a preparation method of a coffee melanoidin pigment and belongs to the technical field of coffee. The preparation method particularly includes the following steps: (a) baking Yunnan Arabica coffee green beans at 200-280 DEG C for 10-30 min; (b) grinding the baked coffee beans into powder, sieving the powder through a sieve in 100-200 meshes; (c) dissolving the coffee powder in boiled pure water according to the ratio (m / v) of coffee powder to water being 1:2-10 at 80-90 DEG C for 10-30 min, filtering coffee residue and collecting a filtrate; (d) performing alcohol separation to the filtrate for 12-24 h according to the ratio (v / v) of coffee liquid to alcohol being 3:7, allowing the liquid to stand for precipitation, and performing centrifugal fermentation for 10-20 min at 1000-3000 rpm; (e) freeze-drying the product in a freeze-drier at -55 DEG C under 0.4 mbar, and crushing a dried product to prepare the coffee melanoidin. The method is simple in operation, is low in preparation cost and is high in yield. The coffee melanoidin pigment is safe, can improve color and flavor of foods, has the anti-oxidizing effect and can be widely used in foods.

Description

Technical field: [0001] The invention relates to a method for preparing coffee melanin-like pigment, which belongs to the technical field of coffee. Background technique: [0002] Yunnan coffee arabica belongs to the Rubiaceae family and belongs to the genus Coffea. The planting areas are mainly distributed in Lincang, Baoshan, Simao, Xishuangbanna, Dehong and other prefectures. It is well-known both at home and abroad for its unique quality and excellent properties. Yunnan arabica coffee is famous all over the world for its "thick but not bitter, fragrant but not strong, slightly fruity taste", and has become a sought-after product in international markets such as Europe, America and Japan. It is comparable to the world's best coffee, Blue Mountain Coffee, and was once rated as a first-class product by the International Coffee Organization (ICO). Small coffee particle size ≥ 5.5mm, moisture (%) ≤ 12, water extract (%) ≥ 22.0, caffeine (%) ≥ 0.8, total sugar (%) ≥ 9.0, pro...
