Description

Preparation method of low-starch highland barley loose oatmeal
Technical Field
The invention belongs to the field of food processing, relates to a process for preparing highland barley energy bars by utilizing an enzymolysis technology, and particularly relates to a preparation method of low-starch highland barley loose oatmeal.
Background
The energy bar is a kind of instant food which has larger energy density, is convenient to preserve and carry and is mostly formed by cold pressing, the history is not long, the energy bar is not a food classification unit in a strict meaning, and the energy bar can be classified into cakes, biscuits and other major categories according to different processes. The energy rod can be designed according to a proper formula to cope with different application scenes. The grain type energy bar represented by the highland barley can also be designed to have a preferential taste and nutrition, and the calorie value is properly reduced so as to meet the leisure tea consumption required by the current market. In order to ensure rich mouthfeel, the reduction of calorie is mainly to reduce starch of the product.
The energy bar made by the conventional process has a hard mouthfeel because the content of glucan in the highland barley is high and the cooked highland barley has a compact texture, and the conventional solution is to correspondingly adjust the cooking process and the puffing effect of the highland barley, and the methods of high-temperature instantaneous puffing, deep-frying puffing, freeze drying after pre-gelatinization and the like are most common but the effect is not obvious.
Disclosure of Invention
The invention aims to provide a preparation method of low-starch highland barley loose oatmeal, which is realized by the following steps:
(1) washing semen Avenae Nudae with water to remove surface floating dust, and adding into boiling pot (or tiltable jacketed pot);
(2) adding clear water about 3 times of semen Avenae Nudae (different semen Avenae Nudae varieties, different water absorption amount, slightly different), opening interlayer steam valve, heating materials, boiling, and maintaining for ten minutes to one hour (depending on semen Avenae Nudae varieties);
(3) cooling to 80 ℃, adding high-temperature resistant amylase (product of Cangzhou summer enzyme biotechnology limited) according to the proportion of 2 to 1 thousandth of the weight of the raw materials, and keeping the temperature for 2-3 hours for reaction;
(4) heating to 95 deg.C or above for half an hour to inactivate enzyme;
(5) pouring into a filter (or a filter tank), filtering to remove liquid, washing with clean cold water to reduce temperature, and collecting highland barley grains;
(6) feeding the highland barley grains into a double-roller tabletting machine to form uniform highland barley tablets. The pressed highland barley tablets have high moisture content and no preservation property, and can meet the product quality requirement only after being dried to ensure that the moisture content is less than 8 percent and screened. The far infrared drier or the tunnel oven can be used for drying; no matter what drying method is adopted, finally, the dried highland barley flakes need to be cooled to room temperature by cold air;
(7) and (3) baking the dried highland barley oatmeal to be golden yellow at the temperature of 160-. Meanwhile, the highland barley wine can be obtained by distilling the recyclable liquid part.
Compared with the prior art, the method for reducing the starch in the highland barley grains by using the enzymolysis biotechnology is the key point of the method. Has the following main characteristics: (1) the raw material adopted by the invention is low-starch highland barley, and the existing reports are few. (2) The existing highland barley oatmeal is generally cured by adopting a high-temperature sand-frying or baking mode, and the invention cures the highland barley by adopting a mode of starch enzymolysis after cooking, thereby reducing the damage to the nutrient components in the highland barley, converting the highland barley starch into maltose and glucose and improving the flavor. (3) The highland barley oatmeal is flavored by utilizing the Maillard reaction, so that the flavor is further improved. The invention can reduce starch, cause the interior of the highland barley grains to be hollow, and can improve the loose feeling during the conventional puffing. The low-starch energy bar can be prepared by using the low-starch highland barley loose oatmeal. The product is convenient to carry, has excellent mouthfeel, has lower total calorie than the conventional product, and is suitable for consumers who like the product and have the worry of the total calorie.
