Abstract

A manufacturing method for tartary buckwheat baked food belongs to food processing and can keep the rutin content by reducing the degradation rate of rutin in the tartary buckwheat baked food. The manufacturing method comprises the steps of boiling water, flatly spreading tartary buckwheat powder on a steaming pot, steaming the tartary buckwheat powder with the boiling water, taking the tartary buckwheat powder out, cooling, smashing and sieving the tartary buckwheat powder, mixing raw materials and auxiliary materials according to proportion, kneading dough, fermenting the dough, dividing the dough into blocks, shaping the blocks, baking the blocks and obtaining finished products. After the tartary buckwheat powder is preprocessed and steamed by being separated from water, more than 70% of rutin can be kept in a dough kneading process. In a fermenting process, most rutin in the tartary buckwheat powder steamed by being separated from water can still be degraded. However, the rutin degradation can be stopped after lemon juice is added into the tartary buckwheat powder, and most rutin can be kept after the lemon juice is added into the tartary buckwheat powder. The rutin can effectively reduce fragility and permeation of capillaries and meanwhile has antibiosis, anticancer and anti-oxidation functions. The manufactured tartary buckwheat baked food can meet the requirements for nutrition and health care, and the bitter taste of the tartary buckwheat food is reduced.

Description

A kind of preparation method of bitter buckwheat bakery
Technical field

Research in the past shows, bitter buckwheat is in process, and in the process of especially mixing with water, the loss late of rutin reaches more than 90%.When after buckwheat powder and water mixing 60min, the content of rutin drops to 0.31g/100g from 3.74g/100g, and meanwhile, the content of Quercetin has increased.Rutin itself does not have bitter taste, nontoxic, mouse mainline LD 50for 950mg/kg.And Quercetin is the main source of bitter buckwheat bitter taste, have a strong impact on the taste of bitter buckwheat food, hinder the exploitation of bitter buckwheat food, and confirm that Quercetin is to cause one of several flavones that biological cell mutation rate is higher, toxicity is relatively large, mouse subcutaneous injection LD 50for 100mg/kg.So how to reduce the loss late of bitter buckwheat rutin in process, to produce saferly, the better bitter buckwheat food of mouthfeel is of great importance to the exploitation of bitter buckwheat.
Summary of the invention
The object of the present invention is to provide and can lower rutin degradation rate in bitter buckwheat bakery, thus the preparation method of a kind of bitter buckwheat bakery of maintenance rutin content.
The present invention includes following steps:
1) pretreatment buckwheat powder: first by water boil, then buckwheat powder is laid on steamer, boiling water steam, then take out cooling, pulverize, sieve stand-by;
2) make bitter buckwheat bakery, process is as follows: supplementary material mixes in proportion → kneads dough → and proof → piecemeal, shaping → curing → finished product.
In step 1) in, the thickness of described buckwheat powder tiling can be 5~10mm, and the time that boiling water steams can be 3~10min, makes buckwheat powder after steaming mix rutin afterwards with water and can preserve more than 70%.Described sieving was 100 mesh sieves, can make so fully to mix thoroughly between powder and can not produce doughball.
In step 2) in, described supplementary material comprises following component, can be by mass percentage: buckwheat powder 22%~66%, flour 0~44%, salt 0.6%~0.7%, yeast 0.6%~0.7%, water 27.7%~32.7%, lemon juice 1%~5%.Step 2) method of the bitter buckwheat bakery of described making can adopt existing conventional method.
The detection of the bakery product of making can adopt following method: 1, extract the general flavone in food, to after the bitter buckwheat biscuit of making and the freeze drying of bitter buckwheat bread, grind, after 60~100 mesh sieves, ultrasonic extraction condition: the pure methyl alcohol of extract, solid-liquid ratio 1:40,60 DEG C of extraction temperature, extraction time 30min, extracting twice.Then by centrifugal extract (5000rpm) 5~10min, 0.45 μ m filter membrane suction filtration for supernatant, filtrate is revolved and is steamed to dry, molten and to be configured to 25mL solution to be measured with chromatogram methyl alcohol weight.Each sample repeats to extract 3 times; 2, the general flavone, rutin content and the non-oxidizability that detect in sample obtain characterization method.
Compared with the prior art, the invention has the beneficial effects as follows:
After Steam by water bath pretreatment buckwheat powder, can in the process of kneading dough, preserve more than 70% rutin; During the fermentation, even also can be degraded by the most of rutin of buckwheat powder of Steam by water bath processing, but add after lemon juice, this degraded has been prevented from, and in other words, adds after lemon juice, can preserve most of rutin.Rutin (citrin) can effectively reduce capilary fragility and permeability, has antibacterial, anticancer and non-oxidizability simultaneously.So the bitter buckwheat bakery of producing like this can ensure the demand of nutrition and health care, can reduce again the bitter taste of bitter buckwheat food, thereby reach the object of promoting product.
