Snack dried bean curd and method for continuously frying same at low temperature

Abstract

The invention discloses snack dried bean curd and a method for continuously frying the same at a low temperature. The water content of the dried bean curd is 40-50% of bean curd. The method comprises the following frying steps of: cutting the bean curd and frying the cut bean curd at a vacuum pressure of 0.06-0.095 MPa and a temperature of 80-120 DEG C for 5-30 min. With the adoption of the method provided by the invention, the snack dried bean can be continuously operated in a frying process so that the frying temperature is greatly reduced; furthermore, the oxygen concentration in a deep fryer is greatly reduced, therefore, the fried food is difficult to fade, change color and be brown, the deterioration degree of oil is greatly reduced, the quality is improved and the technology is simplified. Moreover, in the method provided by the invention, frying is carried out under a vacuum and low-temperature condition; the frying process is completed at a low boiling point; the oil temperature is less than or equal to 90 DEG C so that nutrition constituents of the dried bean curd are not broken; meanwhile, the frying process can be continuously operated and the technology is simplified.However, as the snack dried bean curd is easy to fold in a sheet shape, a part of the snack dried bean curd is not fully fried.

Description

technical field [0001] The invention relates to a dried leisure bean curd and its low-temperature continuous frying method, in particular to an improved frying process, which can reduce the boiling point of oil and realize continuous operation. Background technique [0002] Dried tofu is made of soybeans, which are processed through processes such as soaking, grinding, pulping, coagulation, pressing, frying, and stewing. Dried tofu is rich in protein, and tofu protein is a complete protein. It not only contains 8 kinds of amino acids necessary for the human body, but also its ratio is close to the needs of the human body, and its nutritional value is high; the lecithin contained in dried tofu can be removed and attached to the blood vessel wall. Cholesterol in it can prevent vascular sclerosis, prevent cardiovascular disease, and protect the heart; it contains a variety of minerals, supplements calcium, prevents osteoporosis caused by calcium deficiency, and promotes bone de...
