Second, the operating point
1. Choose a white lotus root that has a high yield, a white color, and a flat product with no surface shrinkage.
2. Peeling can be mechanically peeled, but it can also be peeled off manually, such as production: The best product for export is being peeled, and its product quality is better controlled than mechanical peeling.
3. The size of the cut block should be determined according to the requirements. The size of the block should be 3 cm x 5 cm. (It is too small to meet the habit of lotus root soup. It is too difficult to dehydrate and dry, and has a long dehydration time and is easy to brown. Change, quality is not good control).
4. Color protection Dehydration The browning of dehydration and drying in the production process mainly occurs when the moisture content is 30% to 40% before peeling, dicing, and drying. Therefore, after peeling and dicing, the color should be soaked in the color protection solution in time (color protection solution mainly consists of 0.1% sodium sulfite, 0.15% calcium chloride, and citric acid with a pH value of 3-4.
5. The soaking bubble time is generally controlled for more than 30 minutes as required.
6. The blanching and boiling water bled for 3-5 minutes to inactivate the enzyme and control browning.
7. The hanging slurry is composed of color-protecting liquid plus 5% pure starch or modified starch. The purpose of hanging pulp is to prevent browning. Due to the long dry time of drying, nitrite is easily decomposed by heat. If not hanging pulp. When it is dried to a moisture content of 30% to 40%, nitrite has been decomposed and does not control browning. If the amount of nitrite is increased, it will result in excessive residual levels of dioxins in the product. Through slurry processing, starch nitrite adsorption inside, control release, slow down the decomposition rate. The purpose of preventing browning is achieved and the starch does not have an adverse effect on the quality of the product.
8. Drying uses medium-temperature and medium-speed drying to ensure that the product surface is smooth and without shrinkage. The temperature is controlled at 70°C and 5°C and it takes 5 hours. The heat source is the best for heating with steam, and it can also be supplied with hot blast furnace hot air.
Third, dehydration thousands of quality indicators
(1) Color: White, uniform inside and outside. (2) Odor: Only the special smell of lotus root, without any other odor. (3) Organizational status: Blocks are complete, uniform in size, and no shrinkage or deformation occurs on the surface. (4) Moisture: The dry moisture content of the loquat is less than or equal to 13%, and the rehydration is good. (5) The sulfur dioxide content is less than or equal to 0.0015 ‰.
Dehydration and dry production
First, dehydration and dry production process. Lotus root → to mud, peeled → cleaning → cutting → color protection → soaking → blanching → hanging pulp → hot air drying → measurement, packaging → finished product.
