Before beginning today's article, small make up want to ask a question: Your home spends the New Year preparative special purchases for the Spring Festival, ate?
Small make up just threw away the day before yesterday ten bags of milk, really Rio feels distressed. But feel distressed also of no help, expired, do not throw having waitinging for Pure Brightness?
Nevertheless with respect to this small issue, let however small pose the question that generated expiration period of a few concerned food. We says ~ one by one below
Alimental expiration period is longer, is antiseptic more?The answer is: Be not such.
Zhongshan university Sun Yixian commemorates the hospital is clinical nutrient division advocate treat doctor He Fengyi to express, the accident of food expiration period, basically mix with technology of food itself character, production pack etc about, do not become direct ratio certainly with the content of antiseptic.
It is with milk exemple, if use pasteurization, heat the grandma 62~65 Celsius, maintain 30 minutes, that expiration period counts a day only, and need is saved in the environment under 4 Celsius.
But if use method of sterilization of superhigh temperature instantaneous, heat the grandma 130~150 Celsius, hold 0.5~3 second, the expiration period can amount to 6 months or above.
Actually, in daily life, everybody and expire food has hit be handed in and many, for instance:
A few food were put very long, did not notice to saw the expiration period eat; Some elder calculate know food expires, hate to part with however throw; Still have a few undesirable businessmen even, can pretend the food that just expired what did not expire...
So the issue came ↓ ↓ ↓
Ate to expire food, is the question big? Can you fall ill?Want to answer this question, the curved turn inside is circled circle but many. So small make up resolve this problem into the following 2 problems:
Q1: Food expires a few days only, never mind?
The answer: You do not know when it deteriorated really!
He Fengyi's doctor suggests, insurance for the purpose of, still do not want edible to expire food, especially fleshy products, egg product and edible oil.
2004 " pack food label general rule beforehand " in, it is about the specification of the expiration period, "Exceed this time limit (the expiration period) , inside proper time, it is OK still to pack food beforehand edible. It is OK still to pack food beforehand edible..
But the newer edition 2011, deleted this specification however. Because differentiate hard really, expire how long food, just be true harmful to human body inedible.
Q2: Do not have smell to change flavour, eat a dot to also have nothing to do with?
The answer: Put too long, nutrition is reduced, harmful microbial meeting increases!
Expire in food, partial nutriment may prediction of a person's luck in a given year. It is with cereal exemple, it is normal to be in save a condition to fall, along with the elapse of time, change of frumentaceous protein, mineral content is not big, but the vitamin is met drop off.
For instance, it is when frumentaceous moisture content 17% when, after 5 months, vitamin B1 content is met loss 30% the left and right sides.
Actually more terrible is, expire in food harmful microbial meeting increases.
Common, wait like salmonella, coliform organisms, can cause the symptom of gastric bowel path such as disgusting, vomiting, diarrhoea. Serious, wait like yellow aspergillus element, cause canceration possibly.
So this reminds everybody, shop (especially food) when, must be careful! Come up against especially below this kind of circumstance, must not buy!
Manufacturing date brushs the food that does not have, must not buyNow, the Duan Yue of the hand that make a holiday of undesirable businessman will jump over " brillant " , expire also can pretend what did not expire.
Jiangsu saves consumer rights and interests to protect committee investigation to point out, in the food such as attune of grain oil, beverage, snacks, sauce, discovered manufacturing date " divide easily, easy fall off " problem.
This gave illegal businessman an opportunity that can be exploited to sbs advantage: Fast overdue food, erase produces date so, build again new went.
Accordingly, should avoid to eat to expire food, must take a heart more.
1.Careful observation food packs the model of written characters that date, expiration period produces on bag, look to whether have alter mark, writing is clear.
At present food wraps bagging to tag manufacturing date, have 3 kinds of kind that print: Gush code is printed, laser is printed, steel seal. Gush code is printed the easiest by alter.
2.Produce the model of written characters of date with hand attrition gently, see date whether can become punch-drunk.
3.Looked to whether produce putrefaction.
For example food color, flavour produced apparent change; Pack not in good condition, appear flat; Or the businessman was not pressed store the condition is deposited, this cold storage however normal temperature is saved etc. These circumstances, "Although be inside the expiration period, also do not suggest to buy or edible " .
4.Buy food to normal bazaar and supermarket, well-known food company.
