Description

Edible salt with hollow structure and preparation method thereof
Technical Field
The invention belongs to the technical field of seasonings, and particularly relates to edible salt with a hollow structure and a preparation method thereof.
Background
The salt is the first of all, is a seasoning essential for people's life, and has the main function of seasoning and increasing the salt. However, excessive sodium ion intake is found to be an important factor for inducing various diseases such as hypertension, coronary heart disease, osteoporosis and the like. The world health organization recommends that the daily salt intake of adults is 5 g, and the dietary nutrient intake survey in China shows that the salt intake of residents in China is approximately 2 times or even 3 times of that of the world health organization by reducing salt.
In order to reduce the intake of sodium, ensure enough salinity brought by salt, meet the requirements of people on delicious taste and health, various large salt industry companies develop various series of low-sodium salt-reducing products on the market successively, but the main form of the low-sodium salt-reducing products is to add potassium chloride to replace part of sodium chloride. The reference intake of dietary nutrients of Chinese residents suggests that the daily intake of potassium for adults is 2g, and potassium is widely present in animal and plant tissues, unlike sodium, and the daily intake of potassium can meet the requirements of human bodies. There is also scientific evidence that excessive potassium intake can lead to disorders or discomfort of the cardiovascular system, neuromuscular system, digestive system and urinary system. The national safety standard GB2721 for edible salt also stipulates that low-sodium salt added with potassium chloride is not suitable for hypertension people taking antihypertensive drugs, and limits low-sodium salt edible people added with potassium chloride.
The umami substance can enhance the sensitivity of human body to the salty taste perception receptor, and when the umami substance is used together with sodium chloride, the human body taste bud can enhance the perception of salty taste, which is the salty taste synergistic principle in organoleptic science. By using the principle of increasing the effect of salty and fresh food and the seasoning technology, the sodium reduction amount of about 20-30% can be ensured under the condition of the same perceived salinity. However, the umami sodium-reduced salt generally contains higher purine components, and is easy to cause gout symptoms after being eaten frequently.
Disclosure of Invention
In view of the above, the present invention aims to provide a hollow edible salt without potassium and purine and capable of reducing the intake of edible salt, and a preparation method thereof, so as to solve the problems of the conventional low sodium salt.
In order to achieve the purpose, the technical scheme of the invention is realized as follows:
a hollow structure edible salt is characterized in that: the weight percentage of sodium chloride in the edible salt is more than 50 percent and less than or equal to 85 percent; the rest is maltodextrin and Arabic gum.
Further, the specific gravity of the edible salt is 0.5-0.7 mg/ml.
Further, the water content of the edible salt is less than 2%.
Further, the paint comprises the following components in percentage by weight: 50-85% of sodium chloride, 10-50% of maltodextrin, 0.1-5% of Arabic gum and 0-1% of calcium silicate, wherein the sum of the weight percentages of the raw materials is 100%
A preparation method of edible salt with hollow structure comprises spray drying with pressure spray drying tower.
Further, the preparation method comprises the following steps:
(1) weighing sodium chloride, maltodextrin and Arabic gum according to a ratio, uniformly mixing, adding water according to a mass ratio of the raw materials to the water of 3:7, and stirring to dissolve to obtain a raw material solution;
(2) connecting the raw material liquid in the step (1) with a feeding pump of a pressure type spray drying tower, wherein the feeding frequency is 25-35 Hz; the pressure of the pressure type spray drying tower is set to be 1-10 kg, the inlet air temperature of a tower opening is 150-200 ℃, the air supply frequency is 18-25 Hz, the induced air frequency is 25-40 Hz, and the pressure in the tower is 130-180 Pa;
(3) discharging after spray drying in the step (2), and drying to control the moisture content in the material to be below 2%;
(4) and (4) cooling the material obtained in the step (3) to room temperature, weighing calcium silicate according to the proportion, adding the calcium silicate into the material, and uniformly mixing to obtain the finished product of the edible salt with the hollow structure.
An application of edible salt with hollow structure is preferably suitable for dry-sprinkled and cold-dressed foods.
Compared with the prior art, the edible salt with the hollow structure and the preparation method thereof have the following advantages:
(1) the specific surface area of the hollow edible salt is larger than that of common edible salt, and the specific gravity of the hollow edible salt is only 1/4-1/3 of that of the common edible salt (the specific gravity of the common edible salt is 2.16 g/ml); the dissolving speed is more than 2 times faster than that of common salt; through comparison of sensory evaluation, the same salty taste feeling is achieved, and 20-30% less salt can be added; due to the hollow structure characteristic of the product, the salt reducing agent is particularly suitable for reducing the salt of dry scattering food, and can effectively reduce the adding amount of edible salt.
(2) The edible salt with the hollow structure is also suitable for hypertension patients taking antihypertensive drugs because potassium chloride is not added, and is also suitable for gout patients because purine components are not added. Therefore, the sodium-reduced sodium salt is more suitable for people and has better commercial prospect.
