Introduction To Frozen Dough Technology

Posted on by blogger

After working for years in the frozen dough industry, supplying frozen products to bakeries, cafes and restaurants, I had the chance and the pleasure to get quite a lot of experience in the production of good quality frozen dough. A good quality frozen dough product is a product which, after having been frozen for up to 6 months, still comes out of the oven as beautiful, appetising, attractive to the eyes and tasty as a fresh product. So it gives me a great pleasure to share with you some of the secrets about frozen dough production.

First don’t get mixed up with “Retarded Dough System” and “Frozen Dough Technology”. Those are two different ways of processing the dough, the first one is very simple and the second one is very much more elaborate.
– The Retarded Dough System is just normal dough that we place in a normal freezer, to be used up at a later time, may be 1, 2, or 3 days later. This dough loses some of its performance capability during the freezing process and cannot be kept frozen for more than a few days only. This is just a convenient process that we can use in some short term situations.
– The Frozen Dough Technology on the other hand is a very detailed and specific way of processing the dough, that enable the user to get the optimum performance out of the dough which has been frozen for a longer period of time. This period of time could be from just a few weeks to a few months; 6 months being regarded as a maximum for a live dough containing yeast. This is exactly what this article is all about.

First, how many kinds of frozen dough processes can we differentiate?
1) Ready to Prove Frozen Dough, good for most yeast dough and puff pastry as well.
2) Ready to Bake Frozen Dough, recommended especially for croissant and Danish pastry items.
3) Part Baked Frozen Dough, good for bread items, not recommended for croissant, Danish pastry items, and sweet bread and bun items.
4) Full Baked Frozen Dough, good for sweet bread/bun and soft roll, not recommended for bread, croissant, Danish pastry and puff pastry items.
5) Raw Frozen Dough Ready to Bake (Proving in the oven), not available yet, new technology still under intense research and development.

Critical points to succeed in frozen dough preparation
1) Make sure that the fermentation process does not start at any stage during the production.
To achieve that: one must control the temperature of the dough during all the different stages of the process, from the very beginning (mixing) to the very end (proving baking).
Ideally dough temperature must not exceed 16C (61F) during the mixing, dividing and filling of the products.
After the blast freezing procedure the ideal storage temperature is from -18C (64F) TO -22C (72F).

2) To keep the dough temperature under 16C (61F), at all time during processing, is the most difficult part and to achieve this goal we need to:
a) Keep the room temperature at between 16C (61F) and 20C (68F).
b) Use cold flour. Before use, the flour should be stored in a chiller (+4C) (39F).
c) Use cold water from a chiller or a water cooler.
d) Replace 25% of the liquid used (water/milk) with ice flakes. Or if ice flakes are not available the use of icy cold water (+2C) (35F) is recommended.
e) Work the dough straight away from the mixer without or with as little rest as possible between the different stages.
f) Freeze the dough, after shaping and filling, as fast as possible and this is when we need a blast freezer to freeze the product very fast up to the core. Why do we need to freeze the dough as fast as possible? The answer is: To bring the temperature deep inside the products to around -8C (17F) to -15C (5F) very fast, around 10 to 30 minutes, depending of the size of the products. This way the ice crystals formed during the freezing process are very small and do not damage the dough structure. If the freezing process is too long (from 3 to 6 hours with a conventional freezer) the crystals formed inside the dough are very big and will damage the yeast and the gluten structure. Then in this case the product will be very long to prove and will not rise to its maximum desired size, this is typically a low quality frozen dough.

Now looking at each kind of frozen dough processes one by one, we can say that for bread items the part baked system is the best and gives very good results. For croissant and Danish pastry items (as well as bread items) the ready to bake system gives outstanding results, but demands strict supervision, good equipment and premise.

Regarding the ingredients used in the production of frozen dough, they are almost the same as for the normal type of dough except two slight differences.
First, the yeast. Instant yeast and fresh yeast are both good to use but we always have better results with fresh yeast, products are faster to prove with more oven spring as well. Also when it comes to the quantity of yeast used, we have to increase it quite a lot (up to 2 to 3 times the normal quantity) to compensate of the yeast dying during the freezing process.
Second, the dough/bread improver used should be a special kind of improver for frozen dough only. There are many brands available on the market.

Hopefully this article has given you some useful things to think about before you start mixing the dough and I really hope you enjoyed this introduction to the process of frozen production.

How Voip Technology Can Change The Way Of Communication

Posted on by blogger

VOIP (Voice over Internet Protocol) is an innovative advanced technology that allows the user to communicate with people through the Internet Protocol. This unique phone technology can effectively reduce charges long-distance calls and provide a relatively less expensive way to communicate.

Thanks to this pioneering technology that has totally changed the mainstream media, which are often very expensive. Today, the benefits of VoIP are being widely used in many large and small organizations. People from different fields are using this service in their businesses as well as households. VOIP is also recognized by other technical names, such as Internet telephony, IP telephony and digital telephony.

Although the names of no matter, what really matters is the function, uniqueness, benefits and the low cost of using this technology. There are several advantages and can be used all by the simple use of this technology over the Internet. In general, to enable VOIP service in your home or business you only need a personal computer, telephone and Internet VOIP.

No doubt, by the use of technology can gain several advantages as low cost calls, the ability to keep in touch with people around the spread, the ability to call any location and many more.

However, in addition to its benefits, there are some drawbacks too, that you may face while using their services, for example, poor signal reception, security theft and any disruption in the VOIP, etc. However, as the popularity of VoIP is gaining increasing attention of people in the world, is constantly being improved every day so you can serve your 100% to its users.

There are many providers that can get VOIP service and you can easily connect your Internet connection with your phone. Therefore, if you really want to save the enormous costs on long distance then only allow VOIP technology services.
The systematic approach to software interactive voice response (IVR) is definitely a boon for many businesses. IVR is primarily useful for many other industries as well as public utility companies, mortgage companies, banks, Healthcare, Customer Relations Department, etc..

Apart from this, the most important features of the IVR software includes the ability to store responses made by callers, provide all the details minute to customers and must be capable of capturing voice responses tone or call Now, the question arises of how much money you have to pay for the technology that allows IVR in your business. Usually costs about $ 3,000 to $ 7,000 for the basic system. The cost may increase further if you want the more sophisticated software and advanced IVR.

Advances In Microscope Technology Means Clearer Results

Posted on by blogger

Microscopes have come an unbelievably long way since they were first developed in the late 16th century. While Antonie van Leeuwenhoek is often credited with being the creator of the first microscope, it was actually one of two optics pioneers who is the real father of the instrument: Zacharias Jansen or Hans Lippershey. Of the three, it is Lippershey who is most widely considered to be its inventor, an idea which is especially credible given that he was also the designer of the first modern-style telescope. Leeuwenhoek would not be born for nearly half a century after the earliest models were first built.

The microscopes of van Leeuwenhoek’s invention provided at best 275 x magnification. For its time it was truly impressive and broke new ground, enabling a host of scientific discoveries and advancing scientific knowledge and medicine in almost every way imaginable. Today of course, even many inexpensive of microscopes are capable of much higher levels of magnification and a variety of new microscopy technologies are available to allow scientists, physicians and researchers to get a close up look at the invisible world around us.

Optics have increased in sophistication by orders of magnitude in the last four centuries, with the lenses being used in microscopes being immeasurably improved and more powerful with every passing year. It’s not only in the design of the lenses used that microscopy has advanced – there are an array of new technologies behind the magnification power of the modern laboratory microscope.

Over the long history of these instruments, we have seen them advance to having a single objective to multiple objectives, the addition of adjustable viewing stages, improved focus mechanisms and the development of the stereomicroscope (actually two microscopes which focus on a single point rather than being one microscope with two lenses).

Microscope illumination has advanced by leaps and bounds along the way. From the earliest days of microscopy when illumination would have meant sunlight or perhaps candles, we have progressed to an age where we have not just high power microscope lenses with magnification power of up to 1000x, but illumination to light the slide from below (known as bright field microscopy) and illumination technologies which exclude scattered light to allow the observer a view of the specimen on the slide and nothing else (a method called dark field microscopy which is also used in non-optical microscopy).

Not only have optical microscopes made progress which would be unimaginable to Hans Lippershey, but there are now microscopy technologies which do not rely on optics and provide us with an incredibly powerful tool for looking deep within the natural world. Electron microscopy has been able to show us the microscopic world in greater detail and at magnifications which go beyond anything van Leeuwenhoek would have dreamed; as high as 1,000,000,000x by using a carefully directed electron particle beam to produce high resolution images.

From the lenses used in modern high power microscopes to stereomicroscopy, advances in microscope illumination and electron microscopy and other non-optical instruments, the history of the microscope has been one stunning advance after another. With each improvement comes new insight and revelations about the world around us. In an uncertain world, one thing that can be counted on is that these instruments will continue to progress and amaze us with the discoveries they facilitate.

New IVF technique IMSI at Morpheus ART Fertility Centers

Male fertility is a real problem and there are indications based on reports from fertility treatment registers in several countries that this is increasing. There are many possible reasons for this increase and the most plausible cause could be the increasing exposure to environment factors that are an outcome of unregulated industrialization as well as lifestyle choices. While we are now constantly warned of the effects of the constant plundering of the environment with visuals of floods and crashing icebergs, we are often oblivious of the reproductive effects of environmental pollution. One example is the evidence that has accumulated over the years into the link between sperm defects and exposure to lead which is an ingredient of common chemicals such as paints that we are exposed to on a daily basis. There are also indications of the toxic effect of agricultural chemicals such as DDT which is widely available and used in India despite a government ban. What is not clear however is the exact mechanism of action of these toxicants on the male reproductive system and modern technology does not allow us to directly link a sperm defect in any individual to a particular substance in the environment. Similarly lifestyle choices and their effects on our health are not surprising. Research does point to the toxic effects of individual lifestyle choices such as tobacco chewing and the indirect effects of decreased physical activity leading to obesity and its possible associated impact on sperm production. But it is sometimes too early to come to a conclusion as the widely publicized and controversial American study on the effects of mobile telephone signals on sperm production in rats was not easily accepted by the wider scientific community.

However research into treatment of this challenging condition has been continuing and has resulted in revolutionary new possibilities. ICSI or intracytoplasmic sperm injection had revolutionized the treatment of male fertility with the ability to use the sperm from men who have had trouble conceiving due to poor quality sperm that had defects in movement, were too few in number or had other problems not detectable by conventional microscopy. In this technique sperm are picked up with a micro-needle and placed within the oocyte. The union of the egg and sperm take place and viable embryos grow out of this union. These embryos are then deposited in the uterus resulting in healthy births in a high percentage of patients. It is reported that thousands of cases have been performed since that path breaking moment in Brussels when sperm were first successfully injected into the center of a human egg. But it has never been entirely clear whether the entire natural sequence of events leading to fertilization is being repeated after ICSI is performed. However the results in terms of live births have been encouraging and as a result there is a definite trend towards increasing use of these techniques. The European society for human reproduction and embryology in its annual reports point to this trend and it is assumed that this increase is both due to an increasing incidence of male fertility as well as increasing confidence in the outcome of this technique.

Another remarkable extension of this technique was when the first successful pregnancies were reported after the use of sperm that were surgically removed from the testes of men who do not have sperm in the semen. Although there were initial concerns about the plausibility of gaining healthy live babies from sperm that are still developing in the testes, the results over the years have given immense confidence to the medical community. As a result thousands of males who could not have imagined having a child have undergone the testicular sperm extraction procedure followed by ICSI and have children of their own.

But sperm pathologies have continued to remain a challenge and ongoing research has yielded few answers to the reason why many men fail to conceive despite all these advanced techniques and seemingly normal partners. There is plenty of evidence to show that genetic defects in the sperm could result in a form of self selection such that these genetically abnormal sperm fail to initiate or complete the sequence of events leading to a healthy embryo. These gene defects are not visible in a normal microscope nor can any sperm that has been exposed to tests to determine the presence of these defects be used for ICSI as these techniques are destructive to the cells. The only test that has shown a relationship to potential is the structural appearance of the sperm cells. These defects can be of numerous types with defects observed in the head, neck or tail of these cells. This simple test of observation is used during the ICSI technique while trying to select out sperm from among the millions of cells. As mentioned above, the most normal looking sperm are selected out using a microscopic size needle at a magnification level 200 times normal. But the power of this selection method is impeded by the magnification level that is achievable by the equipment that is designed for ICSI. This has led to researchers trying to more efficiently perform ICSI by discerning the various structural abnormalities that would not be visible with conventional technology.

A group of researchers in Israel first published their work on the IMSI (Intra-cytoplasmic morphologically selected sperm injection) technique in 2005 and this study was subsequently supported by clinical studies showing its efficacy in groups of patients with extremely severe sperm defects. In this advancement over ICSI, the sperm can be more closely examined reaching magnification levels more than 7000 times. Looking at sperm at this magnification shows defects in sperm head that cannot be seen in conventional microscopes used for ICSI. This has been an exciting new development and numerous births have been reported from extreme cases of male infertility.

Research into male fertility continues with some researchers taking up the challenge of finding methods of treatment in males whose testes do not have capacity to produce any sperm. There have been attempts in other species to create sperm cells from embryo stem cells but modern science is a long way from achieving this successfully with human cells. Until then ICSI and its more advanced version IMSI will be the answer to thousands of couples frequenting fertility clinics for treatment of sperm related problems that are not amenable to medicines or surgery.

Screen Sharing to reduce CO2 Gas Emission

Posted on by blogger

The screen sharing technology simply lets you control the mouse and keyboard of one computer while you sit at another computer within the shouting distance or on the other side of the world. This technology is really useful for the business people to cut the travel cost and save time. With screen sharing, you can also help the planet to be healthy by reducing CO2 gas emission.
Help Reduce Carbon Emissions with Screen Sharing

While screen sharing technology is praised for making the completion of everyday business and personal tasks easier and quicker, it is still unknown to many that such a simple solution carries great benefits for the environment. By organizing business and private meetings to be held live over the web, the need to travel for a face-to-face meeting is radically diminished or even removed. The obvious result of such technology is a reduction in CO2 gas emissions and lower levels of air pollution. Another major benefit for the environment in using screen sharing technology is avoiding deforestation. Professionals would now use screen shots and emails instead of taking printouts and documents for face-to-face meetings.

On average, a single ton of paper would be produced from 17 trees. An individual tree is said to produce on average 476,637 sheets of paper.

Now just think about how many companies are using papers everyday for handouts in meetings and for other purposes. According to the Economist Intelligence Unit Report the majority of decision-makers see screen sharing software as a viable alternative to cut CO2 emissions. So by implementing a sustainable carbon-neutral meeting culture, businesses can raise their profile as pioneers. There are numerous web conferencing vendors available in the market that serves its best to the users and our planet as well.

It is now possible to do the right thing for the planet and provide an excellent opportunity for companies to be visibly “green”.

Advantages of Screen Sharing Technology

Helps business people to train workers or update clients
Helps employees to collaborate and share knowledge with other co-worker or colleague from any location
Reduces the hassle of traveling
Saves money and time in traveling
Helps in reducing CO2 emissions
Helps through avoiding deforestation
