At present, the domestic potato chips making general use of the atmospheric pressure of high temperature Fried method, the oil temperature is 180 ℃ above mostly, high temperature make oil hair smoke, not only increase fuel consumption, and from deterioration, and even make the product produce some harmful to human body material. Vacuum Fried method although can be an effective way to solve the above problem, but the necessary equipment huge, investment cost is higher. Introduce the low temperature of atmospheric Fried potato production technology, effectively avoid the high temperature on food nutrition composition of the destruction, and the influence on the quality, the products not only color flavor good, and quality of a material is crisp, both of oil to prevent high temperature deterioration, and reduce the cost, the product safety and health.
A, technological process: raw materials to choose to clean skin, and protect color to dry and slice, Fried, seasoning and packaging
Second, key operation
1, raw material treatment choice antipests, not of germination of high quality potatoes cleaning to skin, the skin of attention when to dig up the potatoes YaYan, slice machine adopts the automatic biopsy, thickness control in 2-2.5 mm. Slice will immediately into prepared potatoes have good protect color liquid, protect color liquid using 0.1% citric acid + 0.1% sodium hydrogen sulfite, protect color time and a half hours.
2, Fried preheated to 140 ℃ to oil or so, press certain material than oil feed, stirring constantly, make uniform heat, and the material is golden brown, it in time. Potato chips Fried optimum technological conditions of low temperature: 150-160 ℃ into the pot, it 160 ℃, material than oil 2-1. Affect the quality of the main factors for material than oil, followed by a pot of temperature, once again into the pot for temperature.
6, seasoning package. With 1% salt, moderate chili powder, five spices power and made into seasonings, and spray and in the finished product, stir well, finished product after cooling with bags seal.
