Corn tea processing technology

Corn tea is a beverage made from cassia seed, which is a combination of corn and medicine. After being baked, Cassia has a strong coffee aroma, which is matched with roasted corn and has a unique flavor after proper processing.

1. Formulation example Baked corn kernels 6 kg, cassia 1 kg, white sugar 7.5 kg, 6 g of protein sugar, 120 mg of ethyl methacrylate, 15 g of potassium sorbate.

2. Process flow Melting and filtering of white sugar, protein sugar, ethyl maltol, potassium sorbate, etc. ↓ Corn, cassia seed → soaking → baking → crushing → leaching → filtration → blending → filling → sealing → sterilization → cooling → finished product

3. Operation points

(1) Raw material selection Choose corn with full grain, golden color and no mold and insects.

(2) soaking The corn kernels are soaked in normal temperature water for 6-8 hours to allow the corn kernels to absorb part of the water, which is beneficial to the flavor generation during baking and the gelatinization of the starch. The cassia seed is washed with water and used.

(3) baking Spread the soaked corn in the baking tray, not too thick, the baking temperature is controlled at about 200 °C, and it is flipped every 2 minutes until the corn is roasted into a brownish semi-foamed shape, and a rich popcorn flavor is produced. until. Cassia is also baked at 200 ° C for 5 minutes, can be broken by hand.

(4) broken In order to make the nutrient-flavored substances in the corn better immersed, the roasted corn is properly broken, and generally broken to 1/4 to 1/3 of the size.

(5) Leaching Weighed crushed corn, cassia seed 6 kg and 1 kg, added 70 kg of water, boiled for 10 minutes, and filtered off the extract. The remaining cha was repeatedly extracted twice, adding 42 kg of water each time for 10 minutes.

(6) deployment The extracts obtained three times were combined and injected into the batching tank. The white sugar is melted in boiling water in advance, and the protein sugar, ethyl methacrylate, and potassium sorbate are respectively dissolved with a small amount of hot water. The stirrer on the mixing tank was started, and several dissolved auxiliary materials were sequentially added, and finally the volume was adjusted to 150 kg (about 150 liters).

(7) Filling and sterilization The corn tea before the filling is filtered again and heated to 80 ° C, and then filled, and immediately sterilized after sealing. The sterilization formula was 10'~15'~10'/115 °C, that is, the temperature in the sterilizer was raised to 115 ° C for 10 minutes and kept for 15 minutes, and the center temperature of the beverage can was lowered to 40 ° C for 10 minutes. After passing the inspection, it is the finished product.

4. Quality Standard

(1) Sensory index Color: amber; smell and taste: rich in roasted corn and coffee aroma; no impurities.

(2) Physical and chemical indicators Soluble solids ≥ 5.5%, arsenic (as As) ≤ 0.5 mg / kg, lead (in Pb) ≤ 1.0 mg / kg, copper (in terms of Cu) ≤ 1.0 mg / kg.

(3) Health indicators The total number of bacteria is ≤100/ml; the E. coli group is ≤6/100 ml; the pathogenic bacteria cannot be detected.

Mottled Waxy Corn

How should I eat maize every day? We need to control the amount of corn, according to the dietary guidelines, the amount of staple food we use in our lives should be controlled at 250 grams to 400 grams, and the ratio of coarse to fine grains is one to three or one to four, which simply means that about 130 grams of corn can be used every day, in addition to the appropriate reduction in the intake of staple food, let's say half a bowl of rice or a steamed bun, so as to avoid excessive calorie intake in our bodies.

It is also important to note that when eating corn, it is advisable to eat the whole cob together to better control our blood sugar. If corn is processed into corn juice or cornmeal food, the nutrients inside are often lost and what remains is basically sugar, which is often higher on the glycemic index and more likely to lead to a rise in blood sugar, for example, the glycemic index of ordinary corn is only 55, but with foods such as cornmeal, the glycemic index often reaches 68, so it is important to eat the right corn.
