Omega-3?

Omega-3 fatty acids are a group of unsaturated fatty acids that cannot be produced by our own bodies. More and more studies show that too low intake of these omega-3 fatty acids can be associated with a series Western chronic disease, both physically and psychologically: overweight, cardiovascular disease, depression, Dementia, ADHD. Moreover, it appears that the omega-3 fatty acid DHA (docosahexaenoic acid) plays an important role in the development of the eyes and the brain in children. We cannot recognise that humans have a relatively large amount of brains compared to their body size compared to other primates. The dietary pattern (rich in unsaturated fatty acids) of prehistoric man would be at the basis of our evolutionary advantage over other great apes. In the last tens of thousands of years our genes have changed little in strong contrast to our diet. The answer to the question “should we eat like a primitive man?” (Flanders ‘ FOOD article 05/04/2012), is therefore largely “yes”. However, this does not mean that we all have to go back to catch fish. New technologies allow them to incorporate these essential fatty acids is our contemporary diet.

Oxidative instability

One of the biggest challenges in the processing of omega-3 fatty acids is the oxidative instability of these compounds. The many double bonds in the carbon chain of the omega-3 fatty acids make these nutrients susceptible to oxidation with fishy taste abnormalities as a result. The risk of oxidation becomes even greater if this omega-3 oil is heated during food processing. Fortunately, there are techniques to make these omega-3 fatty acids less susceptible to oxidation.

Current techniques

Antioxidants are added to the oil to reduce the amount of free radicals.

Polar impurities can be removed by steam deodorization or an earth treatment.

Spray drying of the omega-3 oil with other materials gives as end result a powder in which micro droplets of oil are encased. Processing of this powder in foodstuffs can give rise to a sandy mouth feeling. In addition, the spray drying is done at a higher temperature with risks to oxidation and taste abnormalities as a result.

Freezing drying has the advantage of being able to encapsulate the omega-3 oil at low temperatures. Although, the result of this process is a porous, spongy structure that allows the oil to oxidize easily.

Omega-3 oil can also be encapsulated in an emulsion to reduce contact with oxygen, spore metals and other substances that can lead to oxidation of the omega-3 fatty acids. The materials for this encapsulation can be either other fats or polysaccharides or proteins. The result are microcapsules that are relatively large and which can easily settle in low viscosity foods as a result.

New OMEGA-3 emulsion technology

As a result of all the abovementioned difficulties concerning the incorporation of omega-3 fatty acids into foodstuffs, Croda developed a new emulsion technique that encapsulates the omega-3 oil in a complex of milk proteins. A mixture of whey and casein proteins is heated to form a complex structure with great molecular weight. This complex of milk proteins forms the interphase between the oil and water phases. The oxidation of the omega-3 oil is prevented by the antioxidant capacity of the 2 milk proteins. The Fosfoserylgroep on the casein protein and the Sulfhydrylgroep on the whey protein capture free racidalen and bind metals that could otherwise initiate oxidation. In addition, the unique combination of whey and casein proteins provides superior emulsifiërende properties of the omega-3 oil in the water phase.

OMEGA-3-cheese

A Spanish study recently indicated that cheese is an interesting food product to enrich with omega-3 fatty acids. Also Croda’s Omega-3 emulsion technique was applied in cheese. The study showed that taste abnormalities by oxidation of the omega-3 oil occurred much quicker in cheese where simply omega-3 oil was added compared to cheese where the omega-3 oil was added in the form of microcapsules containing milk proteins.

Difference Between 4K and HDR

Difference Between 4K and HDR : Is ultra HD the same as HDR

Posted on Leave a commentPosted in Technology

4k and HDR are the terms which is in so much trending among people since PS4 pro and Xbox One X.but do we know what are 4K and HDR? What is the difference between 4K and HDR? SO, here are the complete details.

What is 4K?

Concerning consumer displays, 4K equates to 3840 x 2160 resolutions of the panel. This means the 4K screen will display 3,840 horizontal pixels and 2,160 vertical pixels. When you multiply these number together, the user will get a display with having more than the combination of 8 million pixels. This is what four
3840×2160 = 8,294,400 pixels
1920x1080x4 = 8,294,400 pixels

The 4K came from the facts when the Hollywood film industry reached to a pixel resolution of 4096×2160 standard, which is a 1.9:1 aspect ratio but since most of the home screens and TV still uses a 16:9 ratio, then the resolution came down to 3840*2160p.

Why should people go for 4K?

According to a report it has been revealed, that majority of the homes have a 4K capable TV. Regarding quality of the picture, the increased resolution provides image clarity and sharpness. It also allows for more extensive panels since 1080p display stretched across a large surface will begin to look blurry with low pixels density.

Is there a lot of 4K content?

Nowadays, most of the blockbusters movies are offering 4K Blu-ray discs. 2160p is becoming more widely available on some of the streaming services like Amazon, Netflix, Vimeo, and Youtube. Some of the high profile 4K Vimeo shows include Jessica Jones, House of Cards and Daredevil.

What are the issues facing in 4K?

Apart from a small library of 4K CONTENT, the user will also need to have a good internet connection for a 2160p stream video. Furthermore, 4K is four times sharper than 1080p.

What is HDR?

HDR stands for high dynamic range. We all have heard about it in cameras, but when it comes to screen technology, there is a twist.
When cameras are shooting in HDR quality, then they are typically taking different exposures to highlight the dark and light information in a scene. And then processing is used to combine the exposure into one picture to provide a right image that is more representative of how we humans perceive light and color.
HDR on Television also aims to represent colors more realistically; it merely uses panels that offer a much more comprehensive range of color gamut as compared to standard RGB Television. According to a report, HD can expand the color gamut by two factor which amounts to more than 75% of visible color spectrum beam.

Why should one go for HDR?

When it comes to image quality, HDR increases the contrast between black and white over the traditional RGB screens. This means that white will look like super bright and black will look like very dark. Colors will look much more vibrant. For example. Onscreen fire effects will seem much warmer. This is a technology which is more noticeable than the upgrade from 1080p to 4K.

Do all 4K TVs support HDR?
No, many of the HDR TVs support a 4K panel, but not all 4K TVs supports HDR. Both of them are separate technologies.

What will I need to enable HDR?
Apart from HDR capable TV, you also need an HDR capable player and HDR movies or shows. Regarding consoles Microsoft Xbox one supports HDR. Moreover, the PS4 Pro supports HDR. Microsoft upcoming new project also will also go to help HDR. To make HDR working, you also need an HDMI 2.0 cable for connection.

Is there a lot of HDR movies and shows?
No, not right now. HDR movies and shows are still in a state of infancy when compared to 4K, but both Netflix and Amazon are working to provide more HDR shows and movies. Some of the existing HDR shows include Marco Polo and Daredevils.

Is ultra HD the same as HDR?

No, both are different. With HDR should not be confused with other big TV of the moments UHD which is also popularly known as 4K. Both UHD and HDR are meant to improve the viewing experience, but they both are different technologies with almost no overlap with each other. It is a matter of quantity and quality.

What is an HDR pro?
HDR Pro is mainly a term which is used for HDR1. LG, which is the second largest TV OEM producer in the world, has launched its entire lineup of 2018 of both OLED and Super UHD LED TVs with the support of Dolby Vision globally.
