Abstract

The invention provides a blueberry cornflake and a production method of the same. The blueberry cornflake can be produced via the following production method which comprises the following steps: uniformly mixing 55-65 parts by weight of waxy corn flour, 20-30 parts by weight of sweet corn flour, and 10-20 parts by weight of blueberry juice; conveying the ingredients into a double-screw extruder to perform extrusion moulding; preparing cornflake with a thickness of 0.2-0.4 mm via granulating and flake-pressing; roasting the cornflake for 8-10 minutes at a temperature of 150+/-5 DEG C; cooling to 55+/-2 DEG C; uniformly spraying 5-8 parts by weight of melted beewax on the surface of the cornflake; and rapidly cooling to a room temperature. As the beewax is sprayed during the production process, the soaking resistance of the blueberry cornflake provided by the invention in a liquid food is better than the soaking resistance of the traditional cornflake, and the blueberry cornflake can also be prevented from absorbing moisture during a storage process simultaneously. Via the added natural blueberry juice and the sprayed beewax in the ingredients, the nutrition of the cornflake is enhanced, and the varieties of the cornflake are enriched.

Description

A kind of blueberry cornflakes and preparation method thereof

Technical field

The invention belongs to food processing field, relate to a kind of blueberry cornflakes and preparation method thereof.

Background technology

Cornflakes normally to take off embryo corn quarrel or to take off the embryo corn flour and make as raw material, are faint yellow, are the uniform sheet of thickness, fatty hardly, aromatic crisp, be easy to digestion, absorb, can be equipped with soya-bean milk, gruel, milk etc. as breakfast, nutrition, convenience, good to eat.

Traditional cornflakes have a shortcoming, are exactly soon deliquescing after the liquid foods such as soya-bean milk, gruel, milk soak, and are no longer crisp, affect mouthfeel, also lost selling point.

Summary of the invention

The object of the present invention is to provide a kind of blueberry cornflakes, overcome above-mentioned shortcoming by the method at its surface uniform spraying beeswax.Simultaneously the present invention has added blueberry juice in the cornflakes batching, make cornflakes contain the blueberry composition, has not only increased the nutrition of cornflakes, has also enriched the kind of cornflakes.

The present invention also provides the preparation method of above-mentioned blueberry cornflakes.

The invention provides a kind of blueberry cornflakes, these blueberry cornflakes can be made by following preparation method: glutinous corn powder 55～65 weight portions, corn powder 20～30 weight portions, blueberry juice 10～20 weight portions are mixed, send into extrusion modling in the twin (double) screw extruder, again through granulation, compressing tablet, make the cornflakes that thickness is the 0.2-0.4 millimeter, cornflakes are toasted, 150 ℃ ± 5 ℃ of baking temperatures, stoving time 8-10 minute, when being cooled to 55 ℃ ± 2 ℃, melt good beeswax 5～8 weight portions to the spraying of cornflakes surface uniform, the fast room temperature that is cooled to of speed.

The dry waxy corn that described glutinous corn powder refers to peel, take off embryo is that raw material is through pulverizing, cross the glutinous corn powder that 60 mesh sieves make;

The dry corn that described corn powder refers to peel, take off embryo is that raw material is through pulverizing, cross the corn powder that 60 mesh sieves make;

Described blueberry juice is blueberries raw juice.

The invention provides a kind of preparation method of blueberry cornflakes, the method comprises the step of following order:

⑴ mix glutinous corn powder 55～65 weight portions, corn powder 20～30 weight portions, makes a material;

⑵ spray into blueberry juice 10～20 weight portions equably in a material under the condition that stirs, and mixes to make the b material;

⑶ send the b material into extrusion modling in the twin (double) screw extruder, again through granulation, compressing tablet, makes the cornflakes that thickness is the 0.2-0.4 millimeter;

⑷ toast cornflakes, 150 ℃ ± 5 ℃ of baking temperatures, and stoving time 8-10 minute, when being cooled to 55 ℃ ± 2 ℃, melt good beeswax 5～8 weight portions to the spraying of cornflakes surface uniform, the fast room temperature that is cooled to of speed is the blueberry cornflakes.

Blueberry juice divides blueberries raw juice and blueberry inspissated juice, and blueberries raw juice forms as raw material squeezes take fresh blueberry, does not add also not sugaring of water.The commodity blueberries raw juice usually adopts the again packing or add with concentrated blueberry juice that the water recovery makes of freezing blueberries raw juice.Blueberries raw juice has the taste smell of natural blueberry, and has kept the main nutrient composition of blueberry.

Beeswax is the secretion of worker bee wax gland, and its main component is organic acid, free fatty, free alkyl alcohol, carbohydrate, carotenoid, vitamin A, aromatic substance etc.When beeswax is applied to food industry, be often used as fruit glaze agent, be used for the surface spraying of food or outer coatings etc., it has well anti-suction, anti-moisture absorption effect.The beeswax that is used for food should meet the requirement of GB GB/T 24314-2009 " beeswax ".

Beeswax is determining its anti-immersion degree in liquid food at the thickness of blueberry cornflakes surface spraying, the more anti-immersion of thicker blueberry cornflakes of spraying, namely can keep not deliquescing of longer time at liquid food, but spraying is blocked up, when edible, can produces the wax sense, mouthfeel and the crisp degree of blueberry cornflakes will be affected, therefore, in order to take into account anti-bubble and mouthfeel, beeswax should be not very few at the quantity for spray on blueberry cornflakes surface, also too much unsuitable, should select a suitable consumption.

Owing to sprayed beeswax in manufacturing process, the anti-bubble of blueberry cornflakes of the present invention in liquid food is better than traditional cornflakes, can also prevent blueberry cornflakes moisture absorption in storage process simultaneously.The natural blueberry juice that adds in the batching and the beeswax of spraying have increased the trophism of cornflakes, and have enriched the kind of cornflakes.
