Getting to know more about Dehydrator

From ancient days, dehydrating food is a perfect method of preservation. Dehydrating is also a good way to handle an excess of any number of fresh ingredients while retaining their nutritional value. Also, it also brings out the fresh strongest flavors in herbs while keeping them around out of season. Presently, technology has presented us with a dehydrator, keeping at bay the old approaches of dehydrating. Foods processed with the dehydrator can be stored for a long period without losing their nutritional importance. Nevertheless, the devices are costly, and many people find it prudent not to buy the appliance since it rarely gets used. There is a variety of alternatives to dehydrate food and how NOT to use a dehydrator. Below are simple and straightforward ways to apply in place of a dehydrator.

Sun Dry Your Foods

This is the most favorite option because the sun is naturally available and costs nothing. However, some people say that this method works better on certain foods than others. This hoax should not dissuade anyone from using sun drying as a method of dehydrating foods. It is a suitable method of dehydrating herbs, fruits, vegetables, and tomatoes. It makes them develop an extra level of sweetness. Cut the item you want to dry into small pieces and place them on a clean and flat surface. Put some mesh material over the food to keep the flies from getting all over it. Leave them in a very sunny spot where they can take a few days.

Use the Microwave

This may sound adventurous to some people. How exactly do you use a microwave for dehydrating food? Most notably, this method is most viable when dehydrating foods that dry faster. For example, herds, fruits such as apples, and some vegetables like spinach. It may take a little bit of trial and error as microwaves vary greatly in heat strength. Ultimately, you will notice great success dehydrating using a microwave.

Use Your Oven

Just like using your microwave, using an oven may be fascinating. It is surprisingly easy to dehydrate fruits and veggies in the oven. Just set it to the lowest settings and put small pieces of fruits or vegetables on a lined sheet pan. Normally, it would take about six to eight hours to dry your items. If you do not want to wait for this long, set the oven at around 225F.

Use a Toaster Oven

Another great option for dehydrating without a dehydrator is using a toaster oven. Simply put the toaster on its lowest setting and leave the door slightly open. This will avoid condensation. It is imperative to not that toaster ovens vary in temperature specifications. Thus, timing will change in each. Therefore, keep your time on the food you are dehydrating. Eventually, you will end up with perfectly dried foods that can be stored for up to a month.

The approaches above make it easy to dehydrate foods without the dehydrator. These are remarkable methods, which involves the use of readily available appliances.…

Tips on Preserving Temperature Sensitive Biological Specimen

It is mandatory that all biospecimens should be well stored and preserved because they take the time to develop. Biological specimens are mainly common in a medical laboratory and biological laboratories. All the biological specimens must be well preserved before the experiments using the most appropriate techniques. Consult Cryosend for proper storage and transportation of your specimen. The specimens should also be stored in pleasant temperatures that will not alter the biological composition of the specimens. Today there are numerous techniques of storing specimens in the laboratory and most of them are very effective even if it all depends on the type of the specimen.

Preserving specimen

Fixation process

Biologically, fixation is the first step in preserving biological spPreserving specimenecimens. It includes the cessation/killing of the normal life functions of the specimen. This step is critical in the process of preserving biological specimens. The process of fixation also stabilizes the biological structure of the specimen.

The biological expert should ensure that the specimen’s tissues are not damaged at all because this process also requires the expert to maintain a small size of the tissue. The process is made possible by keeping the specimen moist before the fixation procedure. This is done by submerging the specimen in a wetting agent some minutes before the fixation procedure.

Dehydrating the specimen

Dehydration can be well explained as the chemical/biological process of removing water from a specimen. The best dehydration agents that are available in the market today are acetone and ethanol. This process is very crucial even if there are possible side effects of the specimen shrinking in size and losing the soluble elements in its structure.

Infiltration process

It’s a crucial process that involves, placing the specimen in a plastic resin. In this step, the specimen is not damaged by resin. The aim of this procedure is to ensure that resin penetrates into the specimen.


It’s the final step that requires you to position the specimen in a liquid plastic. The procedure involves the use of three molds namely; small capsules (e.g. gelatin), flat-embedded capsules and flat dishes. The process is quite paramount because it determines the orientation f sectioning gelatin and BEEM in times when the specimen does not have polarity.

The flat dish molds are useful when the specimen is large or when the specimen is somehow impractical; the flat-embedded capsules are used when the specimen requires an orientation process to a particular position in the liquid plastic.…
