Embodiment 1

[0074] The preparation method of the acid leavening agent provided by the present embodiment may further comprise the steps:

[0075] (1) Weigh 500g disodium dihydrogen pyrophosphate and place it in a rotary mixer, then take 25g of pyrophosphoric acid solution with a mass fraction of 50% and dilute it with water to 100mL, make a spray liquid, and add it to a rotary mixer, wherein , the purity of the disodium dihydrogen pyrophosphate is 95%, pH=4.1, and the particle size of the disodium dihydrogen pyrophosphate is 20-100 mesh;

[0076] (2) Pyrophosphoric acid solution is mixed with disodium dihydrogen pyrophosphate in the form of pressure spraying, stirred evenly, and carried out hydrothermal reaction, exhausting heat in time with exhaust fan in the reaction process, wherein, the pressure of the pressure spraying is 0.1Pa , the rate is 5mL / min, the rotation speed of the stirring is 30 rpm, the temperature of the hydrothermal reaction is 120°C, and the time is 30min;

[0077] (...

Embodiment 2

[0081] The preparation method of the acidic leavening agent provided by this example is basically the same as Example 1, the only difference is that in step (1), the mass fraction of 50% pyrophosphoric acid solution is replaced by 14g.

[0082] The product prepared in this embodiment was subjected to chemical analysis, and the pH value of the aqueous solution with a mass fraction of 1.0% was determined to be 3.05. The molecular structure of the product was analyzed by X-ray diffraction as figure 2 shown. From figure 2 It can be seen that in the acid leavening agent prepared in Example 2, the content of disodium dihydrogen pyrophosphate is 99.0%, and the content of monosodium pentahydrogen phosphate is 1.0%.

[0083] The neutralization value is determined by the neutralization potential measurement method in the FCC standard. The neutralization value was determined to be NV=105.

[0084] by comparison figure 1 and figure 2 It can be found that compared to figure 1 , ...

Abstract

The invention relates to the technical field of fermentation, in particular to an acidic leavening agent with a high neutralization value and a preparation method and application thereof. The acidic leavening agent is mainly composed of disodium dihydrogen pyrophosphate, the neutralization value of the acidic leavening agent is larger than or equal to 100, and the pH value of an aqueous solution with the mass fraction of the acidic leavening agent being 1.0% is 2.5-3.5. The acidic swelling agent has the advantages of secondary swelling, secondary processing, controllable and adjustable reaction speed and the like. More prominently, the neutralization value of the acidic leavening agent is high, and the neutralization efficiency can be remarkably improved when the acidic leavening agent is matched with sodium bicarbonate for use. Therefore, compared with the conventional disodium dihydrogen pyrophosphate, by using the acidic leavening agent, the sodium intake can be reduced by about 40%, the fermentation efficiency is greatly improved, and the food is safer and more beneficial to the health of a human body.

Description

technical field [0001] The invention relates to the technical field of fermentation, in particular to an acidic leavening agent with a high neutralization value and its preparation method and application. Background technique [0002] Acid leavening agents have been used in the baking industry for many years, and the neutralization value of acid leavening agents can reflect the efficiency of dough fermentation. Commonly used varieties of acidic leavening agents include potassium hydrogen tartrate, sodium dihydrogen phosphate, potassium dihydrogen phosphate, ammonium dihydrogen phosphate, calcium dihydrogen phosphate, disodium dihydrogen pyrophosphate, alum, burnt alum, sodium aluminum phosphate, etc. Among them, burnt alum and sodium aluminum phosphate are acidic leavening agents with rapid response and relatively high neutralization value. [0003] However, excessive intake of aluminum will cause great harm to human health. It will cause a large loss of calcium in the body...
