Two Practical Potato Processing Techniques Explained in Detail
1. Jam Making Recipe: 4 kg potatoes, 4 kg granulated sugar, 10 g citric acid, a small amount of carmine red pigment and food flavoring, 2-3 g sodium benzoate. Method: First wash the potatoes, steam them until cooked, peel them, spread them out to cool, then mash them into a paste with a pulping machine. Then pour the granulated sugar into a double-layer pot, add an appropriate amount of water and boil to dissolve, pour in the potato paste and stir so that the potato paste and sugar water are mixed, continue heating and stir constantly to prevent scorching. When the slurry temperature reaches 107°C-110°C, use citric acid water to adjust the pH to

Detailed Explanation of Key Points of Potato Storage and Primary Processing Technology
I. Storage Technology 1. Pit storage. Choose a site with high, dry terrain, and dig a trench 0.8-1.5 m wide and 0.9 m deep. Put potatoes pre-stored in a cool place into the trench for storage when freezing is about to occur, spreading the tubers loosely to a thickness of 40-50 cm, placing a bundle of corn stalks every 1 m to make a ventilation tube, with the ventilation tube extending 0.5 m above the ground, covering with a straw curtain, and covering with soil when the temperature drops, with a thickness not less than the frozen soil layer; the top of the trench should be raised. 2. Stack storage method in a ventilated storage warehouse. The potato pile is 1.3-1.7 m high. 2 m wide, and every 2-3 m a

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

Processing Methods and Techniques for Dry-Salted Icefish (Large Icefish)
The processing technique for dry-salted crystal icefish is simple and convenient for storage, and because this processing method preserves the inherent flavor of icefish, it is more welcomed by consumers than salt-dried products. 1. Processing workflow: raw materials → cleaning → alum water soaking → secondary drying → stacking and cooling → packaging → storage. 2. Key operational points: (1) Raw material handling: First remove mixed fish, shrimp and other impurities, pour the icefish into a wooden barrel pre-filled with half a barrel of clean water, add a few drops of edible oil, stir by hand for 2 min

Detailed Explanation of Key Processing Techniques for Minced Fish Canned Products
The processing of minced fish canned products was developed on the basis of minced fish product processing. Such items as boiled fish balls, fried fish balls, seasoned minced fish, etc., can all be processed into canned foods. These canned products have the unique flavor of minced fish products. Here, only the seasoned eel minced fish canning is taken as an example. (1) Process flow: raw material handling - grinding meat, pounding and kneading (adding seasonings) -> filling into cans -> pre-sealing -> vacuum sealing -> sterilization -> cooling. (2) Key operation points: 1. Raw materials: select ice-fresh or frozen eel with good freshness; spoiled fish must not be used.

How is Acetes processed? A detailed guide to Acetes processing technology
Acetes, namely Acetes chinensis, also known as small white shrimp, water shrimp, etc., belongs to the class Crustacea, family Sergestidae, with a laterally compressed body and a thin shell. Body length is generally 2.5-4 cm. The rostrum is short and small, roughly triangular in side view, with the lower margin oblique and slightly curved, and the upper margin bearing two teeth; the telson is very short, rounded at the end, without spines, and the posterior half of the lateral margins and the terminal margin bear feather-like setae. The first three pairs of walking legs are tiny chelate, and the posterior two pairs are completely degenerate. The body is colorless and transparent, with only the mouthparts and the second antennae flagellum red, the ventral surface of the sixth abdominal segment slightly red, and the base of the endopod of the uropod bearing 3-8 red spots

How to process Schisandra seeds? Detailed explanation of the correct processing method
After the Schisandra fruit ripens and is harvested, select plump, large, disease-free Schisandra fruits, soak them in warm water (40-45°C) for 3 days, rub off the flesh, pick out the seeds, then use water separation to remove the shriveled grains, and store them in a ventilated, dry place. After drying, carry out stratification. The stratification method is to fully mix the prepared seeds with 3 times their mass of wet sand; the sand's moisture level should be such that it does not form a ball when squeezed by hand. Dig a pit trench of 60cm×60cm×60cm, with the seed-and-sand mixture at a thickness of 40cm, cover with 15cm of soil, then cover with a
