A Comprehensive Guide to Potato Processing Techniques
The potato is one of China's major agricultural products and can be grown all over the country, with enormous production potential. Besides being eaten fresh, processed into starch, or cooked into Chinese and Western fast food, potatoes can also undergo many kinds of further processing. 1. Potato jam First, wash the potatoes clean, remove any rotten or sprouted parts, then peel them, place them in a steamer and steam until cooked, then take them out and spread them to cool. Next, rub them through a sieve into a uniform potato mash and set aside. Take white granulated sugar, water and sour water (that is, the sour water used in a vinegar workshop; mix a small amount of thin rice (porridge) with bran and put it in a vat, transfer it from vat to vat for one week, once a day, and the filtered sour water is used as a vinegar starter), put them into a pot and boil until 110°C, then pour the potatoes into the pot, and use an iron shovel to keep turning them constantly, stirring while pressing, until all the potato mash is broken up, while at the same time preventing the bottom of the pot from scorching. Continue heating to 115°C, then add citric acid and coloring. And control its pH value at 3-3.2. At this point, because the temperature is too high, it is necessary to turn and stir frequently to prevent scorching. Lower the temperature with a low fire, and when the material in the pot reaches 100°C, add the fruit food flavoring and nutritional additives into the pot, stir evenly with an iron shovel, and it becomes potato jam.

Detailed Explanation of Value-Added Processing Technology for Potato Starch Waste Liquid
The waste liquid from potato starch production is rich in nutrients, and it is a pity to discard it, while it also pollutes the environment. People have attempted to process potato starch waste liquid for use in the food industry, but have hesitated because the treated starch juice has a peculiar off-flavor unique to potatoes. To effectively utilize potato juice, a new process using glucose invertase treatment has emerged in recent years, which not only effectively removes the unpleasant taste from the juice, but also yields a product rich in sugars, amino acids, organic acids, minerals and other nutrients, which can be used as

How is candied potato processed? A full breakdown of the detailed processing technique
1. Material selection: Select potato tubers that are uniform in size, plump, smooth on the surface, and free of green spots to make candied potato. 2. Shaping: Wash the soil off the tubers with clean water, remove the skin and wash again, then cut into blank pieces of various shapes as needed. 3. Soaking: Put the shaped blanks into a container, pour in a certain concentration of dilute limewater and soak for 16 hours, then take them out and rinse in clean water 4 times, 2 hours each time. 4. Boiling the blanks: Put the soaked blanks into boiling water and boil for 20 minutes, then put them into clean water

Detailed Explanation of Potato Harvesting, Storage and Processing Techniques
I. Timely harvesting. Potatoes intended for storage are best harvested when dry matter accumulation is at its maximum and the tubers are fully mature. Spring potatoes should be harvested in early to mid-June, while autumn potatoes should be harvested in early November and must not be exposed to frost. Whether spring or autumn potatoes, if rain occurs before harvest, harvesting should wait until the soil has dried appropriately. Freshly dug tubers have tender skins and should be left on the ground to air for 1-2 hours, then collected after the potato skin surface has dried slightly. However, they must not be sun-dried for long periods in summer; after harvest they should be promptly stored in a cool, shaded place. During storage, strict selection should be carried out, removing tubers that are diseased, damaged,

Detailed Explanation of Coarse Potato Starch Processing Technology
Process flow: Potatoes → washing → grinding → potato residue separation → sedimentation → drying → coarse starch. Key operating points: (1) Grinding into slurry: Select potatoes with high starch content, pick out rotten and diseased potatoes, place them in a washing tank, add clean water and stir with a stick to wash the potato pieces clean. Put the washed potato pieces into a grinder, add water while grinding, grind into starch slurry, and let it flow into a receiving tank. (2) Separation: Use coarse and fine flat screens twice respectively to screen out the potato residue from the starch slurry, or put the starch slurry into a cloth bag, tie the bag opening securely, place it in a tank

How is potato processed? An introduction to several common processing methods
I. Making jam from potatoes. First wash the potatoes clean, remove any rotten or sprouted parts, then peel off the skin, place them in a steamer and steam until cooked, then take them out and spread them to cool. Next, rub them through a grater into a uniform potato mash and set aside. Put white granulated sugar, water and sour water (that is, the sour water used in a vinegar workshop; mix a small amount of thin rice porridge with bran, place it in a vat, transfer it from vat to vat for one week, once a day, and the filtered sour water is used as a vinegar starter) into a pot and boil until 110°C, then pour the potatoes into the pot, and use an iron shovel to constantly turn them, pressing while stir-frying, until the potatoes

Processing and Utilization of Potatoes
I. As Feed Both the tubers and the starch residue of potatoes can be fed to livestock and poultry. According to experiments, feeding 50 kg of potatoes to pigs can increase meat by 2.5 kg; feeding dairy cows can produce 40 kg of milk or 3.5 kg of butter. Feeding each chicken an average of 71 g each of chopped, cooked potatoes and mixed feed per day can increase annual egg production by 30 to 50 eggs and save 20 kg of concentrated feed. II. Extracting Starch Every 100 kg of potatoes generally yields 12.15 kg of starch. The extraction process is relatively simple: first wash the potatoes, then mechanically crush, grind,

Processing and Production Method for Flavored Dried Potato Tidbits
Process flow: potatoes → washing → peeling → trimming → dicing or cutting into strips → precooking → cooling → disulfide solution treatment → drying → puffing → adding flavor enhancers → packaging → finished product. Key operating points: ① Peeling: using alkali peeling or infrared radiation peeling gives better results. ② Shaping: cut into dice, strips or other shapes according to product requirements. ③ Drying: the moisture content of the raw material should be strictly controlled; when the moisture of the raw material drops to 2.8-3.5%, drying can be stopped. ④ Puffing: use air

Processing Method and Detailed Steps for Sweet and Sour Garlic
The processing of sweet and sour garlic includes raw material selection, peeling, salting, changing vats, sun-drying, ingredient preparation, pickling and packaging. For the raw material used to process sweet and sour garlic, garlic bulbs that are neat and plump, with white skin and fresh, tender flesh should be selected. They are graded and sorted, that is, 20 bulbs per kilogram for the special grade, 30 bulbs per kilogram for Grade A, and more than 30 bulbs per kilogram for substandard. Peeling: use a knife to cut off the roots and stems, peel off the garlic skin wrapped around the outside of the bulbs, wash clean in clear water, and drain off the water. Salting: according to the ratio of 100kg fresh garlic bulbs to 10k salt
