① the process of raw materials acceptance → selection → washing → peeled → cleaning → pre-boiled → rejection of water → frying → throwing oil → mixed salt → cans → exhaust → sealed → inspection → finished.
② operational points (a) raw material acceptance. Selection of fresh, full particles, dry, no moth-eaten, no mildew and other inclusions of high-quality corn. (B) Peeling. The mixed solution of 2% ~ 3% sodium hydroxide and 0.2% ~ 0.3% fructic peeling agent was heated to 90 degrees Celsius, corn was added to the peeling agent for 15 to 20 minutes, and the ratio of corn to solution was 1: 2; remove the release of mobile water rinse mixing or scrambling to go to the net skin and cap tips. (C) pre-cooking. The corn into 0.1% ~ 0.15 aqueous solution of citric acid, heating and boiling for 50 to 60 minutes; the quality of corn by the pre-cooked 1.5 to 1.6 times the original quality, with a centrifuge to shake off the water. (D) frying. Formula (kg): flower oil l00, propyl gallate 0.03, citric acid 0.015, alcohol 0.09. Preparation of law: the first propyl gallate, citric acid and alcohol into the container to dissolve, add it to the oil mix. Fried: the pre-boiled water after the corn into the 170 ~ 180 degrees Celsius oil fried until the fish float out after the fish, its color was light yellow or golden yellow; fried 3 to 5 minutes.
