Description

Technical Field

[0001] The invention relates to the technical field of kumquat fruit powder, and in particular to rich kumquat fruit powder and a preparation method thereof. Background Art

[0002] Huangpi is a fruit that is abundant in tropical and subtropical areas. "Compendium of Materia Medica" and "Guangdong Tongzhi" record: If you eat too many lychees, eat Huangpi to relieve the problem. Huangpi can be eaten fresh, but it can also be salted or candied into cold fruit, which has the effects of digestion, gas, and heat removal. Huangpi has a short ripening and picking period, so its preservation method mainly adopts the preparation of jam, candied fruit, and salting. At present, the popular varieties in the market are chicken heart seeded Huangpi and seedless Huangpi. The flesh of seeded Huangpi is milky white, mostly transparent, sweet and mellow, and has a strong flavor. The flesh of seedless Huangpi is light yellow, thin skin, thick flesh, juicy, sweet and crispy. Compared with seeded Huangpi, seedless Huangpi is famous for its large fruit, thin skin, delicious taste, no residue, bright color, thick flesh, and seedlessness.

[0006] Preferably, the rich wampee fruit powder comprises the following raw materials in parts by weight: 35 parts of seedless kumquat pulp, 35 parts of seeded kumquat juice, 4 parts of kumquat extract, 15 parts of white sugar, 35 parts of carrier, 1 part of citric acid, 0.15 parts of vitamin C, 0.1 parts of sweetener and 0.08 parts of preservative.

[0007] Preferably, the carrier is at least one of dextrin, modified starch, colloid and cellulose.

[0008] Preferably, the sweetener is at least one of mogroside, steviol glycoside and sucralose.

[0009] Preferably, the preservative is at least one of potassium sorbate, fermented whey liquid, nisin, and rosemary extract.

[0010] Preferably, the seedless kumquat pulp is prepared by washing and draining the seedless kumquat, pre-freezing it at -20 to -30°C, and grinding it with a freezing mill to obtain the seedless kumquat pulp.

[0011] Preferably, the seeded kumquat juice is obtained by squeezing the seeded kumquat, separating the juice from the residue, and obtaining the seeded kumquat juice and the kumquat residue.

[0012] Preferably, the method for preparing the Huangpi extract is: The yellow peel residue is dried at low temperature, crushed, and pressed into 0.2 mm thin slices to obtain yellow peel thin slices; The kumquat peel pieces are subjected to supercritical CO2 extraction, 70% alcohol is used as an entrainer, and the ratio of kumquat peel pieces to the entrainer is 1:0.5. The obtained crude kumquat peel extract with seeds is filtered and concentrated to a solid content of 12%, which is the kumquat peel extract.

[0013] Preferably, the conditions of the supercritical CO2 extraction are: extraction pressure 25-30Mpa, extraction temperature 45-50°C, separation pressure 7Mpa, and separation temperature 35-40°C.
