Job’s tear grains are the seed kernels of Coix lacryma, a dual-use plant of the gramineae family, which has high nutritional value and unique medicinal value. In recent years, with the popularity of health food, in foreign countries, especially in Japan, the development of Job’s tears food is more in-depth and extensive, the use of Job’s tears to produce a lot of health food, such as medicinal wines, beverages, flavored sauces, fast food powder and so on. China has also done a lot of research and development work.

Nutritional composition of Job’s tear grains

Nutritional Composition of Job’s Tears

Job’s tears in the six nutrients complete, carbohydrates for barley in the main energy-supplying substances, the content of about 65%, second only to rice, wheat, corn and other cereal crops, the main component of the starch, particle size uniformity, shape is more regular, most of the oval or truncated oval, the starch granules of the crystalline structure of the A-type, more difficult to paste, lower transparency, poor thermal stability, but the cold paste stability is stronger, easy to be digested by the body, can alleviate the pain of the body, and can be used for the treatment of the disease. It is easy to be digested by human body, which can reduce the burden on stomach and intestines and help to strengthen the body.

Protein

Protein content of about 17%, exists in the endosperm cells between the starch granules, of which 20% of the protein is divided into three major categories, namely, serum proteins, and gluten, alcohol soluble proteins, the rest of the protein. The protein content in Job’s tears is higher than any protein content in rice and noodles, which has important nutritional value and also important health care functions.

18 kinds of amino acids are relatively complete, of which the essential amino acids are about 4.99%, 100g protein essential amino acids were 0.5g tryptophan, lysine 1.9g, methionine 2.6g, phenylalanine 4.9g, threonine 3.0g, valine 5.7g, leucine 13.6, isoleucine 3.9g and the proportion is in line with the needs of the body, and the seed kernel of the glutamic acid content of the higher. It belongs to the characteristic amino acid of presenting fresh flavor, and glutamic acid is an important amino acid in the biochemical metabolism of brain tissue, so the barley protein belongs to high quality protein.

Fat

The fat content is about 5%, which is nearly 30 times higher than that of rice, which is mainly neutral fat (triacylglycerol ester >90%, triglyceride is about 5%), and there are two kinds of oleosin subunits (H-oleosin, L-oleosin) and one kind of oleosin calponin.

After the fat of Job’s tears was processed and analyzed for its chemical composition using GC-MS technology, it was found that Job’s tears had a high content of unsaturated fatty acids, such as oleic acid and linoleic acid, which accounted for 51.6% and 32.2% of the total fatty acids, respectively. These unsaturated fatty acids have the functions of relieving excessive cholesterol in the blood, enhancing the membrane permeability of cells, preventing the aging of myocardial tissue, and preventing atherosclerosis.

Trace elements

In addition to the three most basic energy substances, Job’s tears also contain a variety of essential trace elements, such as Ca, Mg, P, Fe, Zn, etc., of which Ca, Mg content is higher, respectively, up to 749.00, 1193.60ug / g. The content of Ca can prevent cramps, bone and bone fractures.

Ca can prevent and control cramps, osteoporosis, etc.; Zn can activate the SOD in the human body, so it can remove the peroxides that cause aging of the human body; Mg and Fe are the basic biochemical reactions of the body’s many cells of the essential substances, and the Mg content of the rice than the 2-3 times higher. Job’s seed vitamin species is relatively small, mainly vitamin B, and a small amount of VE, of which VB1 0.25 mg/100g., VB2 0.18 mg/100g., VB3 4.80 mg/100g, with smooth skin, reduce wrinkles, eliminate blemishes and other cosmetic effects, of which VB1 can also cure foot fungus, reduce the inflammation of the skin and other reactions.

Job’s tears in the application of food

Puffed food

The milled white barley with germ is washed with water and soaked for a short period of time to make its water content reach 20%-25%, and then put into the dryer and dried under the temperature of 70℃-120℃ to reduce the water content to 12%-15%, at this time, the alpha degree of barley is 10-20%, and the dried barley is put into the tempering tank.

Put 30% of the modulated barley and 55% of the polished rice, 10% of the refined corn and 5% of the seasoning into the blender, after mixing and homogenizing, send it into the puffing machine, heat, extrusion, puffing treatment that is granular or stick puffed food at this time a variety of raw materials contained in the starch is completely α.

Job’s tear grains cookie

Will be fine milled barley after washing and drying, the use of pulverizer for crushing, and then put the barley powder into the casserole lightly baked, and then put into the steamer.

The steamed barley powder was taken out of the pot and cooled, and when the product temperature was reduced to about 35℃, the seed curd was added and stirred well.

Put the barley powder mixed with seed quartz into small containers, put it into the quartz room, and under the temperature of about 38℃, make the barley powder all quartz (the surface is yellowish-green) after 7-8 hours, and then take it out from the quartz room to make it ripe, put it for about 5 hours, dry it at 90℃ with a dryer, and pulverize it.

Mix 70% barley flour with 30% medium power wheat flour, add appropriate amount of sugar, grease and water, mix at 37℃ for 30 minutes using a dough machine, and then wake up for 40 minutes.

After the risen, it is pressed, modeled, put into the oven and baked at 320℃ for 4 minutes, after baking, the surface of the cookies is sprayed with 12-14% edible fat, and then after cooling, it is the finished Job’s Tears cookies.
