Oxygen Scavenger for Nuts Against Rancid Flavor
Nuts,have strong skins , containing one or more seeds , such as Chinese chestnut , almonds, etc. Nuts are the essence of plants,they are generally rich in nutrients and contain high levels of protein, oil, minerals and vitamins. They have excellent effects on human growth, development and physical enhancement.At the same time, eyes and brain can also be bright by eating nuts. Hazelnuts, walnuts, almonds and cashews are known as the "four great nuts in the world".
Nuts contain 36.0% protein, 58.8% fat, 72.6% carbohydrate, vitamin B, vitamin E, trace elements (phosphorus, calcium, zinc, iron), dietary fiber and so on. In addition, it also contains monounsaturated fatty acids, polyunsaturated fatty acids, including linolenic acid, linoleic acid and other essential fatty acids of the human body. The benefits for human's health of nuts are shown in the following aspects:
1. Reduce the risk of type 2 diabetes in women.
2. Reduce the rate of sudden cardiac death.
3. Eliminate free radicals. Free radicals are very reactive and react with cellular tissues and DNA in the body, causing toxicity and damage. Studies have shown that some nuts, such as sunflower seeds, have a stronger ability to scavenge free radicals, compared with strawberries and spinach.
4. Help your brain.
5. Improve your eyesight.
Matters needing attention:
1.The best time to eat nuts is during the meal. This is because eating nuts after a meal can cause an excess of energy of the day. Eating nuts in the meal is beneficial to enhance our sense of satiety, especially the large almond, small almond, hazelnuts which contain a high amount of dietary fiber, the effect is the best.
2. How to eat nuts. Nuts can be cut up or eaten whole, but each has its own pros and cons, depending on the individual. When eating whole big almond, the feeling of full is strong, the effect that controls blood sugar rise after meal will be good.
The storage requirements of nuts is low temperature, low oxygen, dry, avoid light, suitable temperature below 15 ℃, relative humidity below 60%, otherwise the fat converted to produce "clams taste" , and can not be eaten any more.
The rancid smell is a bitter, malty, pungent smell of oil oxidized and rancid under the action of oxygen, sunlight, water and temperature. The rancid food is unpleasant and unappetizing , but more worse , eating rancid food will lead to the intake of large amounts of oxidative free radicals caused by oil deterioration, which will increase the risk of cardiovascular and cerebrovascular diseases and cancer. Eating rancid food may cause nausea, vomiting, abdominal pain, diarrhea and other symptoms of the digestive system. Long-term consumption may also induce peptic ulcer, fatty liver and other diseases. In addition, the peroxide fat free radical produced during oil deterioration can also destroy the enzymes in the human body, so that human metabolism disorders, the performance of inappetence, insomnia and forgetfulness.
Therefore, in order to avoid the consequences of eating rancid nuts, it is necessary to put deoxidizer during storage. Deoxidizer refers to a chemical reaction using iron and oxygen, using water and salt as catalyst, while promoting the reaction itself, because it 's using reactive iron powder (reduced iron powder), so it can absorb oxygen in food packaging bags effectively. Deoxidizer is non-toxic and tasteless. Deoxygenation is complete. The time required for deoxygenation is short.
Compared with other fresh-keeping methods, deoxygenating fresh-keeping agent in food packaging has several advantages:
1. Small investment and low cost
2. Simple operation
3. Long preservation time
