recently have many of my friends ask me, it should be how to save enough at home to drink soup soup of water, such as milk, such as chicken soup, such as lotus seed soup tremella. These things very good nutrition, healthy drink every day, but at home on 12 people, a pot of soup两碗one with it, there is too much trouble, efficiency is too low; and soya-bean milk machine was purchased to do a quantity of 4 bowls. So good things, bad place to throw away, not a pity?
In theory, milk or milk or chicken broth or are not easy to save things. Let's enjoy them, because are nutritious and delicious taste. However, these same micro-organisms will become a reason to love them. Micro-organisms and people, growth and reproduction require substantial nutrients. Food protein, vitamins higher microbial enjoy them more.
On the other hand, the propagation of micro-organisms also need a lot of moisture, but also required a suitable environment. Although beef is rich in protein but do too little moisture, so easy to save. Hawthorn果丹皮film category, although there is a lot of nutrients, but too much sugar, acid too strong, will inhibit microbial growth and reproduction, so relatively easy to store. Milk and broth like this? Neither too acid nor too sweet, not too salty ... ... suppress bacterial growth factors, they are not a nothing.
so think about using traditional methods of food preservation are not hopeless. But one way left: bactericidal sealed, that is, to do canning road. Although we do not have to do canning machines, but not impede the use of its basic principles to preserve food.
us on soya milk as an example, talk about them at home how to save it for a week.
1 be able to prepare two confined, but also heat-resistant bottles, such as space bottle, or special insulation严实Cup. Around the capacity of each bottle with a considerable quantity of drink. Put them thoroughly cleaned, and then dry.
soya-bean milk machine produced the milk, are just boiling hot milk. So, we need to preserve it, must be heat-resistant containers. At the same time, to get killed for food long-term preservation of bacteria, it is necessary to guarantee that there will be no more oxygen into the bacteria and go, so after盖严containers must be airtight, watertight. High-quality space bottles (be sure to taste the kind of products are not, if the odoriferous note are poor quality, the heat release possible toxic substances) be able to tighten, it is appropriate to preserve foods soups.
2 Add beans well put foam bean milk machine, at the same time burning some boiling water. Procedures in the production of milk is about to be completed when the space put to use boiling water bottles containers look hot, it hot up there, at the same time play a bactericidal action.
3 in the production of milk when the process is complete, draining a bottle of water space, immediately poured into the boiling milk, but not to do too full , leaving the space equivalent to around one-fifth of a bottle of capacity gaps.
4 put the lid loosely covered, but not to tighten, stay around a dozen or so seconds, then screw the lid tight to the most.
5 Wait for milk at room temperature for natural cooling, after cooling to room temperature, and then it into the refrigerator. It can be stored at 4 ℃ for one week.
6 put out milk preservation, re-hot look, you can always drink it!
basic idea of this method are:
put the container with boiling water scalding that kill most bacteria; - Packaging sterilization
also boiled milk, and boiling when there is no live bacteria; - & mdash ; contents sterilization
not put things into bacterial sterilization containers, then sealed up, which continue to be the residual heat to kill bacteria, and closed after the bacteria have access to the outside. - aseptic filling and confined
This allows a longer period of time to preserve food, without corruption happened. As for how storage time depends on you whether or not the operation of the details of norms, as well as the extent of the container airtight. Since the operation at home, after all, not enough detail, the extent of the bottle sealed canned so far less strict, so is not like canned two years as regular gentle.
in the laboratory, using this method, I once put on红豆汤sealed tube, the room temperature kept at 1 year and 3 months months. Point out when there is no bad. Of course, the time at home than many of the Strict operation. But even my introduction of this common home operations, put milk preservation of 12 weeks is not easy!
outside apart from milk, all kinds of soup, all kinds of porridge, a variety of soup, any substantial moisture content of food, can be repeated. So, we will save a lot of worries, you can boil a soup, drink several times. Let me only a little trouble is that the space bottle brush is a very troublesome thing, to use a bottle brush that can clean the brush ... ... taking into account this aspect, I am afraid that is still used in confined ideal insulation Cup.
