Introduction To Frozen Dough Technology
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.

[Top]Txtlocal MD Darren Daws says SMS leads the way for mobile marketing
As the mobile industry comes of age and becomes more sophisticated, it is widely predicted that more companies are choosing to spend a larger percentage of their marketing budget on mobile advertising and applications. The benefits of SMS becomes clear; campaigns need to capitalise on using SMS to support their overall marketing strategies and use messaging as the main force driving customers to the Internet.
This view was echoed by some of the worlds biggest brands at the latest MMA forum. Gavin Mehrotra, Director of International Media for the Coca Cola Company, started his presentation stating categorically that “SMS is the number 1 priority at Coca Cola in mobile” and that you need it to reach just about every person on the planet.
We also know that SMS gives a campaign the added power to communicate with your target customer and build on the relationship you have with them based on permission and trust. Adding SMS to a campaign allows consumers to text for more information so the follow-up is able to become more targeted; we have seen this work in every sector. In the Arts we have worked with English National Opera who used an SMS campaign to increase ticket sales for late availability, an investment of 500 in SMS marketing brought a return on investment of an amazing 8000 in ticket sales. Papa Johns Pizza use SMS to market special offers at times that they want to build sales, in fact across all sectors we are experiencing a growth in ROI as campaigns are measurable in a way they havent been until now.
Combine this with the growth in the use of Smartphone technology and its clear why campaigns are benefiting from improved targeting with SMS. No longer are you limited to 160 characters of text, the use of Smartphone technology and the public acceptance of tiny URLs on social media platforms, means that SMS can be used as tool to link to a bigger picture. SMS can now be used as the hook needed to direct the reader to where they need to be online, faster than if they were left to their own devices. Links to apps, videos and web pages are easily incorporated into an SMS message, making SMS a vital tool working hand in hand with other mobile marketing tools to achieve greater ROI for every mobile campaign.
At Txtlocal, we work with clients of all sizes and shapes from English National Opera, Malmaison Hotels and Liverpool University to much smaller owner operated brands like Shelleys Restaurant in Warrington, we can create campaigns that generate a real response – quickly. Any tool which allows a business owner to grow their customer data and intelligence, and then allow you to communicate targeted messages to them directly is powerful, and its right there in your hand the humble mobile phone.
Its safe to say that if the world’s undisputed number one advertising brand, Coca Cola says categorically, SMS is priority number 1, then surely other businesses large or small need to operate with the same view.
[Top]LED HDTV Technology On Television Today
LED’s also referred to as lighting emitting diodes, are electric factors that exhibit an apparent coloring dependent on some level of latest place inside the diode. higher present produces darker colors, jointly with vice versa, in accordance thinking about the lighting spectrum. LED’s have been implemented in electronics for decades, as well as the newest innovations in LED solutions exclusive brought us this sort of significant type objects as HDTV and several LED-based toys and supplies.
High Definition tv may be considered a latest growth in tv set up broadcast and viewing in which an electrical signal is broadcast providing a bigger resolution inside the image inside the display than what a regular tv can. The image often clearer and much more extremely correct in definition that conventional tv by getting displayed on one of a few of significant types of monitors. one is plasma tv for pc technology. another is certainly fluid crystal display (liquid extremely display) know-how.
Encouraged solutions arrives in the direction of engage in much more prominently in tv as backlighting for all screens. The real fluid crystal screen, the identical solutions for just about any electric watch, is darkish by method of its nature, and youngster should be see a scene concerning the tv screen, LED solutions is carried out to brighten the display from at the rear of so concerning create the image noticeable concerning the viewer.
LED’s are large by nature, and the development on the full-screen LED TV is currently under design construction business, particularly in the pants pocket size TV market. Many TVs overseas that get into the pocket TV category are sold in LCD format, and, once again, are backlit by LED technology. The introduction of TV sets that use LED’s to form the main picture is literally being developed overseas, and in an experimental manner with the U.S.
The backlighting ability linked to LED technology was first implemented with the early 1990’s in Personal Digital Assistants and hand-held gaming system and cell phone screens. The particular technology has propagate around many electronic products from MP3 players and therefore portable DVD players.
[Top]Why use less Iframe
The iframes provides a simple way to embed the content of a website to another site. But we need to be careful of using the iframe. iframe created scripts and css DOM elements created by 1-2 orders of magnitude slower than the other.
Use iframe page normally does not contain too many iframe, to create a DOM node takes time so they do not account for a large proportion. But it will bring some of the other issues: onload event and connection pooling (connection pool).
The Iframes blocking page load
Timely trigger window onload event is very important. onload event trigger the browser “busy” indicator stops, telling the user that the page has been loaded. When the onload event to load delay, it gives the user the feeling is that this web page is very slow.
window onload event to trigger all iframe loaded (contain elements inside). Safari and Chrome, set dynamically through JavaScript the iframe SRC avoid this blocking situation.
The only connection pool
The browser can only open a small number of connections to the web server. The old browser contains in Internet Explorer 6 & 7 and Firefox 2, only a domain name (hostname) open at the same time two connections. Increase in the number of restrictions in the new version of the browser. Safari 3 + and Opera 9 + for a domain name at the same time to open four connections, Chrome 1 +, IE 8, and Firefox 3 can be open at the same time six.
Some people may want to iframe will have its own separate connection pool, but not like this. The vast majority of browser, the main page and the iframe shared these connections. This means that when the iframe load resources may run out of all available connections, thereby blocking the loading of the main page resource. If the iframe content more than the contents of the home page, which of course is very good. But the content is usually the case, iframe was not the contents of the home page is important. Then iframe ran out of available connections is not worth. One solution is the important element of the main page is loaded, and then dynamically set the iframe SRC.
The top 10 U.S. sites use iframe. In most cases, they use it to load ad. This is understandable, also a logical solution, a simple way to load the ad service. But keep in mind, the iframe will give you the page performance impact. Whenever possible, do not use the iframe. When does require cautious use them.
