  • Ocean Acidification: Absorption of Carbon Dioxide - Hanna Instruments Slovenija
    effect on many different activities on earth from the plants on the ground to the clouds in the sky One major effect resulting from carbon dioxide is the acidification of the world s water supplies In a recent article from Environmental News Network researchers from the University of Glasgow show how ocean absorption of carbon dioxide is increasing its acidity causing shells to become more brittle and vulnerable to severe weather events and predation Ocean acidification as the process Ocean acidification is the process in which carbon dioxide from the atmosphere is absorbed by the ocean reacting with the seawater to form carbonic acid this formation of carbonic acid is gradually but surely lowering the pH of the ocean Hydrogen ions are released following the formation of carbonic acid and these hydrogen ions bind to carbonate to form bicarbonate When this happens carbonite concentrations decrease making it difficult for calcifying species such as mussels to build their shells of calcium carbonate Mussels draw bicarbonate ions from seawater and use proteins in their bodies to make crystals of calcium carbonate to form their two layer shells In more acidic water there are less bicarbonate ions available for the mussels to make their shells Using pH meter for measuring water s pH While this may seem like a modest problem the hindrance of growth development and reproduction of smaller marine organisms such as shellfish krill and plankton can result in a breakdown of marine food webs Not only would this affect larger marine organisms but it would ultimately affect the commercial fishing industry and the livelihood of those in the industry One way in which we can detect the increase of carbon dioxide is by measurement of our water s pH by use of a pH meter The measurement of pH can help users better understand the chemistry of our oceans Hanna Instruments carries a variety of pH meters suitable for measuring the pH in the lab in the field and on the go Portable Meters HI9829 Multiparameter Portable Meter Rugged waterproof and easy to use the HI 9829 is the ideal meters for field measurements of lakes rivers and seas Both meters display 1 to 12 parameters simultaneously from up to 15 user selectable parameters HI2020 edge Multiparameter Meter Edge s groundbreaking design is the culmination of Hanna s vision design capabilities integrated production and world class R D edge is a single meter that can measure pH Conductivity and Dissolved Oxygen and is incredibly easy to use Benchtop Meters HI2212 Benchtop Meter with Three Point Calibration The HI 2212 is a pH and temperature benchtop meter Calibration can be performed at up to three points using five standard and two custom buffers This instrument features manual or automatic temperature compensation with the HI 7662 temperature probe HI22091 pH mV Meter with Manual Temperature Compensation The HI 22091 pH mV Meter with Manual Temperature Compensation MTC and Analog Output provides a simple to use cost effective method of measuring pH The

  • Monitor the Content of Sodium Chloride in Olive Brine - Hanna Instruments Slovenija
    at time of harvest green olives picked when they have obtained full size but before the ripening cycle has begun semi ripe olives picked at the beginning of the ripening cycle when the color has begun to change from green to reddish brown ripe olives picked at full maturity and are typically shades of black and brown The curing process of olives When raw olives are picked from the tree they are hard and very bitter due to the presence of harsh phenolic compounds The curing process assures these unpalatable phenolic compounds are leached out and broken down the process is also responsible for generating favorable metabolites from bacteria and yeast such as organic acids probiotics glycerol and esters Raw olives are traditionally cured by soaking in a brine solution for 6 to 12 months during which time the solution is periodically changed The unwanted bitter phenolics leach into the brine solution while the solution itself acts to soften the skin of the olives The duration of the curing process can be decreased by first soaking the raw olives in a dilute lye solution typically composed of 2 to 4 sodium hydroxide NaOH for 1 to 3 days The lye solution acts to rapidly remove bitter phenolics before transferring the olives into a brine solution If the lye solution is utilized in the beginning of the curing process olives only require soaking in the brine solution for as little as a few weeks The concentration of the brine solution Brine solution consists of water salt and occasionally oil the concentration of the brine solution depends on the type of olive being cured and the point at which it is used in the curing process If too little salt is present in the brine solution there is a risk of unwanted

  • Measuring the Concentration of Flavored Sugar Syrups - Hanna Instruments Slovenija
    more Measuring the Concentration of Flavored Sugar Syrups Twitter Share on Tumblr Published 17 September 2015 Concentrated syrups are used throughout the food and beverage industry from flavoring coffee to producing soft drinks The concentration of sucrose not only affects the taste of the final product but also the aroma shelf life and potential for bacterial growth As sucrose is the most common sugar used in syrup products sugar content is typically reported as percent Brix Brix one Brix is equal to 1 gram sucrose per 100 grams of solution Flavored syrups minimize brewing time and counter space Coffee is one of the most popular beverages consumed worldwide and is available in a myriad of varieties and flavors Coffee can be flavored by enhancing the coffee beans with oils in the roasting stage or by adding flavored syrup to the finished brew A coffee shop that brews flavored beans requires many different carafes to hold each type of flavored coffee Alternatively if flavored syrups are used a company simply brews regular roasts and adds the syrup after Flavored syrups can be added to hot cold or specialty beverages as well as desserts Using flavored syrups opens up a variety of offerings to customers while also minimizing brewing time and counter space The risk of carrying flavors over between brews is also decreased Sugar syrup the most expensive and essential ingredient in crafting a quality beverage In the production of flavoring aids sugar syrup is the most expensive and essential ingredient in crafting a quality beverage Cane beet or corn sugar is mixed with treated water to create the sugar syrup or base typically around 63 Brix Flavoring is then added to the base via extracts Extracts are available as natural or artificial tinctures or powders or a combination of the

  • How to Measure Calcium Chloride In Canned Vegetables - Hanna Instruments Slovenija
    preservation efficiency Canning as a method of preservation One of the most popular techniques that has stood the test of time is canning Canning as a method of preservation can be traced back to the early 1800s The invention of canning was a result of the French government offering a cash reward for an affordable efficient means of preserving large volumes of food At the time the French government needed a way to increase availability of food supplies for armies fighting in the Napoleonic wars Inventor Nicholas Appert observed that food cooked in sealed glass jars would not spoil unless the seal was broken However the fragile glass jars proved to be inconvenient for transport so the use of steel cans for canning was introduced Often home cooks can their own fruits and vegetables by packing them into glass jars heating and finally sealing them to prevent the growth of bacteria Industrial canning primarily uses tin coated steel cans or aluminum cans These cans are internally coated with an epoxy resin to prevent the leaching of metals into the food In conjunction with the canning process itself chemical additives are frequently used to further prevent degradation of the product Benefits of using calcium chloride CaCl ₂ While the heat and pressure used during canning extends the shelf life of foods manufacturers may still add preservatives like sulfites and calcium chloride to further increase longevity retain freshness and improve texture Calcium chloride CaCl₂ is used in a wide variety of food products including cheese tofu and sports drinks because of its effectiveness as an anti caking agent stabilizer and thickener Calcium chloride can be used to adjust for mineral deficiencies during the cheese making process or even during beer brewing Canned vegetable and pickle manufacturers often use calcium chloride as a
