Potential application in food industry
There is a great promise of application of ice structuring proteins in food that are frozen. Ice structuring proteins can inhibit re-crystallization during freezing storage, transport and thawing, thus preserving food texture by retarding cellular damage and minimal loss of nutrients (for fruit and vegetables like strawberries, raspberries, tomatoes) by reducing drip (Griffith and Ewart, 1995, Feeney and Yeh, 1998, Breton et al., 2000, Wang, 2000). Re-crystallization in frozen food occurs when temperature fluctuates during storage or transit, resulting in coarse texture. This technique is well suited to ice cream (Warren et al., 1992). Ice structuring proteins also find use in chilled and frozen meat, where large ice crystals may form intracellularly, resulting in drip and loss of nutrition during thawing. Since ice structuring proteins are located extracellularly in freeze-tolerant organism, these proteins can be added to food by physical means such as mixing, injection, soaking, or vacuum infiltration, or even by gene transfer (Venketesh and Dayananda, 2008).
Ice structuring proteins in ice cream
Ice structuring protein does not affect the quality of ice present at any given temperature but influences the size and shape of the ice crystals formed; crystals produced being rod shaped rather than usual round ones. Manufacture of ice cream and edible ices has the product mix entering the freezer at 5°C and extruded at nearly -6°C where approximately 60% of the final ice structure formed. Clarke et al., 2004 studied the ice crystal size distribution in ice cream as affected by ice structuring protein of winter wheat grass, before and after temperature abuse (cycling between -10°C and -20°C e...

Conclusion
Ice structuring proteins are natural products that form part of a normal diet through their occurrence at high concentration in fish and vegetables. Their diversity and various activities show that the proteins are intriguing parts for use in preserving the quality of foods during chilling frozen storage. Large ice crystals destroy the texture and taste of ice cream. So, use of ice structuring protein is suggested as natural ice crystal growth inhibitor in such products. However, selection of ice structuring protein is based on its easy availability, its changes in certain chemical properties during processing of products, its taste and its related impact on food and food properties, safety and cost.
Everyone is looking for better and healthier life! People today pay more and more attention to the food they eat, they want it to be healthy and tasty, on the other side modern life is so dynamic and eventful, that the food must be fast. So you need to come up with something that will support all these needs. The great solution is Frozen Yogurt. It is a refreshing, savory dessert that combines the flavors and textures of ice cream and sherbet. Frozen yogurt is a new-comer in the dessert market. Nevertheless, “the history of frozen desserts dates back thousands of years to Asia where water ices were first made.’’ (wiki) Yogurt was brought to the U.S. in the early 1900s and steadily increased in popularity as a health food item over the next several decades. By the 1970s, with the popularity of ice cream technology was transferred to the production of frozen yogurt. But it’s entry into the dessert market was a distinct failure—consumers complained that it tasted too much like yogurt. Relaying on consumer demand for a sweet product that tasted like ice cream, TCBY opened its first store in 1981. The highest popularity comes to Fro-yo by the mid 1990s. But in the late 1990s as Americans turned their attention to high-protein, high-fat diets, demand for frozen yogurt slowed considerably. Low-fat foods such as frozen yogurt fell out of favor as food trends preferred higher fat and lower cost ice cream at the turn of the millennium. Trends changed back to frozen yogurt in the mid 2000s with the advent of live probiotic powder-based mixes. Over the last decade the production of frozen yogurt has grown multi-million dollar business with dozens of competing companies.
The simplest answer is that the antifreeze doesn’t allow the icefish’s blood to freeze in the cold temperature hence the name

We at Temple Consulting have completed an analysis of Ice-Fili’s current corporate standing using data collected over the past several years. Using tools such as Porter’s Approach and SWOT we have analyzed the internal and external environments and have recommended several strategic plans of action. Current areas for improvement such as marketing initiatives and re-evaluation of distribution channels will increase sales and profitability almost instantly. Long term plans such as lobbying against luxury tax on ice cream, partnerships with franchise vendors, and bringing new products to the market, performing an IPO, and planning more global efforts will help keep Ice-Fili rooted as the industry leader in Russian ice cream production for years to come.
Despite of general properties of enzymes, the properties also varies from where it comes from and how it been produced. For instance, the enzymatic saccharification method in lignocellulosic bioethanol is generated by hydrolyzing cellulose and hemicelluloses. This method gets high attention because of its higher theoretical yield compared to other methods (Taneda et al., 2012). Acremonium cellulolyticus with high activities of cellulase, amylase and pectinase enzymes allow it for the easy separation of solids/liquids in potato pulp, resulting in high saccharification efficiency and a high recovery rate of products (Gao et al., 2014). On the other hand, Enzyme-modified carboxymethyl starch (ECMS) is beneficial in enhancing water holding capacity, emulsion stability and improving sensory characteristics of sausages with a declined fat content (Luo and Xu, 2011). Lipases and phospholipases of dormant cotton seeds have stability in heat, various media and nature of the hydrolysis of the lipids properties (Rakhi...
Although NRFC believe estimation of pizza sales could base on Contadina pasta's 24% market-penetration rate, more conservative calculation should take different ranges of penetration rate into consideration. By choosing three possible penetration rates of 5%. 15% and 25%, the estimated results are demonstrated in Exhibit 1. In all three scenarios, kit only concept will not make up to company's expectation. For kit and topping concept, only if penetration rate reach to 15%, launch decision could be supported.
Thesis: Low temperature biology, or cryobiology, has the possibility, and may very easily and very drastically affect everyones' lives in the future. Through rapidly approaching cryobiological medical procedures and techniques, the presence of intense ethical issues may play an important role in many everyday decisions that do not now exist.
Due to protonic natureconsists of protein, it is smooth and water resistant and it is the outermost thin layer.Meanwhile there is a propensity to mistake primary wall with the cuticle, but these are particular and distinctive structures botanical view. During their life cycle, at some stage, cuticle are presented in the air, usually consider a characteristic of cells [10]. The structure of the cuticle has been determined that it is often extremely thin as comparatively few plants. The general principles explained by Lee and Priestley that are appropriate to the cuticle. These substances primarily is in an oily film in the form of deposit, travel through the primary wall, later it shrinks to varnish-like cover known as cuticle. The state of combining and nature of the fat are significant in order to defining the kind of cuticle. For example, in comparison to sodium oils, potassium and magnesium, calcium salts of unsaturated fatty ac-ids having minor solubility. The comparative proportions of oils in a thinner cuticle bases in the soil can affect the cuticle’s thickness because oils are more
Introduction: A phase change is a result from the kinetic energy (heat) either decreasing or increasing to change the state of matter (i.e. water, liquid, or gas.) Thus saying, freezing is the phase change from a liquid to a solid which results from less kinetic energy/heat. Also, melting is the phase change from a solid to a liquid which results from adding kinetic energy/heat. So, the freezing and melting point of something is the temperature at which these phase changes occur. Therefore, a phase change will occur when a vial of 10 mL of water is placed into a cup of crushed ice mixed with four spoonfuls with 5 mL of sodium chloride for 30 minutes. If 10 mL of water is placed in an ice bath, it will then freeze at 5 degrees Celsius because the kinetic energy will leave quicker with the ice involved. The purpose of this lab is to observe what temperature the water must be to undergo a phase change.
Emulsions are important in food science. Not only do they provide an important sensory aspect in many foods, but a functional one as well. From hollandaise to ice cream, getting hydrophobic and hydrophilic molecules to play nice with each other can be a difficult task. According to Modern Cuisine, it was previously thought that Hollandaise, a classic French emulsion of egg and butter, could only be made by letting butter drip from natural heat of the hand. Of course, modern science has taught us that, with the use of emulsifiers, these mystic mixtures can be created without the voodoo and magic once thought necessary. This paper will discuss emulsions as applied to hollandaise, chocolate, hot dogs and their characteristic pH, moisture content, shelf stability and quality of viscosity. An explanation of the chemical processes that occur between the raw ingredients of each food and the relationship between the structure and function of their components will be explained, as well as the importance of the chemical changes that take place during production. The characteristics that define these foods as emulsions will be compared and contrasted to further elucidate the mystery of the emulsion. Bon Appetite!
For the most part ice cream is a dessert that most people would think that salt with would be a bizarre thing to put with it. But most of the ice cream makers or sellers know it helps with bringing down the temperature of the freezing point. “Since the ice cream isn’t just water, it needs to be a little below 32°F to freeze. When using a crank ice cream machine, you frequently have to add more salt and ice, so you can watch the process of melting ice more than once.” (Physics Buzz) The community wouldn’t know how to make ice cream if it weren't for experiments like
The history of ice cream goes all the way back to the Fourth century B.C. Early allude to this amazing delicacy involve the Roman emperor Nero (A.D. 37-68) who demanded ice to be brought down from the mountains and merged it with fruit toppings, and King Tang (A.D. 618-97) of Shang, China who had a stroke of genius to creating ice and milk combinations. Ice cream was most likely token over from China back to Europe. Over time, recipes for ices, sherbets, and milk ices progressed and were distributed in the well liked Italian and French royal courts. After the dessert was imported to the U.S., it was distributed by many well-known Americans. George Washington and Thomas Jefferson served it to their guests. In 1700, Governor Bladen of Maryland was recorded as having served it to his guests. In 1774, a London caterer named Philip Lenzi announced in a New Y...
