Vegan Wines, These Animal Products Are Also Potentially Allergenic for Consumers www.martinvialatte.com VEGAN GUIDE wines TECHNOLOGICAL The Origins of Veganism Veganism is a movement that began in the United Kingdom around 70 years ago, initiated by Donald Watson and inspired by several great thinkers like Voltaire and De Vinci. It consists of refusing to exploit animals in any way. Stricter than vegetarians, who do not eat meat, in addition to not consuming food that comes from REPRESENTATION animals, vegans do not consume any products that OF VEGETARIANS ACROSS have caused suffering to an animal. THE WORLD Reliable data on vegan populations is rare. However, statistics estimate that the population of vegans in the USA (the largest in the world) has doubled since 2009 and is close to 2.5%. And wine does not escape that rule. Above and beyond Less than 10% and above 3% the allergenic potential of some animal proteins like casein, egg albumin and isinglass, some wine drinkers Between Between 5 and 9.9% 3 and 4.9% lead a vegan lifestyle. They aim to eliminate the use of any animals in wine-growing and wine-making. Many vegan logos can now be found on bottles of wine (first logo on wine in France in 2014). “Veganism is a doctrine according to which humans should live without exploiting animals.” Developing alternatives to animal-based fining agents 1 Plant proteins as alternatives to gelatins Aware of this evolution in consumer trends, the company At the end of the laboratory testing process and the 3 Martin Vialatte has been working on the development years of industrial testing in wine cellars, pea proteins of non-animal fining agents for over 15 years.

  • Brewing Industry - Preparation of Isinglass Finings
    Solutions for Your TOUGHEST MIXING Applications in FOOD Brewing Industry - Preparation of Isinglass Finings THE FIRST NAME IN HIGH SHEAR MIXERS Brewing Industry - Preparation of Isinglass Finings Lager beer is brewed using “bottom fermenting” yeast which sinks during fermentation. A storage period follows to ensure all the yeast has sunk to the bottom. Demands for a shorter storage period and increased productivity in large-scale breweries has led to the use of finings to accelerate sedimentation. The use of isinglass finings was originally confined to traditional British and Irish beers, brewed with “top fermenting” yeast which rises during fermentation. Spent yeast and other solids are precipitated by the addition of finings, either in the barrel (with traditional “cask conditioned” beer) or in bulk prior to filtering. Isinglass is a protein obtained from several varieties of fish. When added to the beer, the isinglass particles attract the yeast and tannins. The finings sink to the bottom, precipitating the solids to leave the beer clear and bright. The Process Isinglass can be supplied in a number of forms: • Ready-to-use liquid. • Concentrated liquid. • Dried floculated particles. • Powder. • Freeze-dried powder/granules. Although liquid forms are easy to use, there are advantages in buying finings in dried form: • Improved shelf life and temperature tolerance. • Solutions can be prepared to meet demand. • Reduced storage requirements. • Formulation can be adjusted to give optimum results in a particular type of beer. Solutions are generally prepared separately before addition to the beer. A typical process using a conventional agitator would be as follows: • The vessel is charged with liquor and the agitator is started.

The investigations undertaken in this project required several discrete development steps: • sourcing of the raw material, • removal of excess fat and mucous from the bladders, • development of processing protocols, • establishment of suitable quality manufacturing and testing procedures, and • identification of the markets and market requirements. Considerable time and effort was committed to the development of the appropriate techniques and equipment necessary for the production of a quality beer fining product produced from fish swim bladder. The procedure, which is currently employed for Isinglass manufacture, begins with sun-dried swim bladders (or maws) which are sourced mainly from developing countries in the tropics (eg Asia, Africa and South America). The maws are then subjected to a sequence of dry milling steps to make the product amenable to incorporation into the beer process stream. The final product has low moisture content and is generally packaged to ensure that it arrives at the ultimate destination in an active form.

Introduction Veganism is a practice of abstaining from the use of animal products, particularly in diet, and is also an associated philosophy that rejects the commodity status of animals. A follower of veganism is known as a vegan. Distinctions are sometimes made between several categories of veganism. Dietary vegans (or strict vegetarians) refrain from consuming animal products, not only meat but also eggs, dairy products and other animal-derived substances. The term ethical vegan is often applied to those who not only follow a vegan diet but extend the philosophy into other areas of their lives, and oppose the use of animal products for any purpose.

Collagen, the mother substance of gelatin, is an albuminoid which occurs to a large extent in vertebrates and also in the flesh of cepha- lopocls. It is the chief constituent of the white fibrils of connective tissue and is also found in bones, cartilages, ligaments, fish scales, etc. CoUagens of different origins are not of identical composition ; how- ever, all show the characteristic albuminoid property of being in- soluble in water and the ordinary protein solvents. The most interesting and commercially important property of collagen is its power to be converted into gelatin by heating with water alone or in the presence of dilute acids. On the other hand, if gelatin is heated to 130° C. it is transformed back into collagen, so that there is a very intimate relation between the two substances. For practical purposes we may consider gelatin to be collagen which has been converted into a soluble form by combination with water. (Other changes have been noted, such as the evolution of ammonia, when collagen is treated with water.) The following table gives the composition of collagen, gelatins from various sources, and of fish glue, which is a crude form of gelatin: Composition of Collagen and Gelatin.

Specifically, the Applicant is seeking an exemption from the requirement to declare isinglass (a processing aid commonly derived from dried swim bladders of certain tropical and subtropical fish) on the label, when present in beer and wine as a result of its use as a clarifying agent. The exemption was initially sought on the basis that isinglass has a long history of use as a fining agent in the production of beer and wine and has not been known to cause adverse reactions in susceptible individuals. The Applicant has now provided evidence that dietary exposure to isinglass through beer and wine consumption is extremely low. Results of oral challenge studies have also been provided indicating that isinglass does not cause an allergic reaction to fish sensitive individuals when consumed at levels substantially higher than the potential exposure levels that may be encountered through the consumption of beer and wine.

Unfined, unfiltered beer may be thought of as consisting of negatively charged yeast cells and uncharged non- microbiological particles in a buffered alcoholic solution. Positively charged isinglass is attracted to the yeast cell walls and adheres the cells together, thereby increasing the floc radius. The larger aggregates settle faster; as they do, they also enmesh the uncharged protein particles.
