From the initial measurements of incoming milk to the final measurements of ripened cheese, pH is the most important parameter for cheese quality and safety control.\u003c\/p\u003e\n\u003cp\u003eAcidification of milk begins with the addition of bacterial culture and rennet. The bacteria consume lactose and create lactic acid as a byproduct of fermentation. The lactic acid produced will cause the pH of the milk to go down. Once the milk reaches a particular pH, the rennet is added. The enzymes in rennet help to speed up curdling and create a firmer substance. For cheesemakers that dilute their rennet, the pH of the dilution water is also critical; water that is near pH 7 or higher can deactivate the rennet, causing problems with coagulation.\u003c\/p\u003e\n\u003cp\u003eOnce the curds are cut, stirred, and cooked, the liquid whey must be drained. The pH of whey at draining directly affects the composition and texture of the final cheese product. Whey that has a relatively high pH contributes to higher levels of calcium and phosphate and results in a stronger curd. Typical pH levels at draining can vary depending on the type of cheese; for example, Swiss cheese is drained between pH 6.3 and 6.5 while Cheddar cheese is drained between pH 6.0 and 6.2.\u003c\/p\u003e\n\u003cp\u003eDuring brining, the cheese soaks up salt from the brine solution and loses excess moisture. The pH of the brine solution should be close to the pH of the cheese, ensuring equilibrium of ions like calcium and hydrogen. If there is an imbalance during brining, the final product can have rind defects, discoloration, a weakened texture, and a shorter shelf life.\u003c\/p\u003e\n\u003cp\u003eCheeses must fall within a narrow pH range to provide an optimal environment for microbial and enzymatic processes that occur during ripening. Bacterial cultures used in ripening are responsible for familiar characteristics such as the holes in Swiss cheese, the white mold on Brie rinds, and the aroma of Limburger cheese. A deviation from the ideal pH is not only detrimental to the ecology of the bacteria, but also to the cheese structure. Higher pH levels can result in cheeses that are more elastic while lower pH levels can cause brittleness.\u003c\/p\u003e\n\u003cp\u003eCheese products can provide a number of challenges for the person that needs to measure pH. Cheese products tend to be solid to semi-solids. Both types of samples will coat the sensitive glass membrane surface and\/or clog the reference junction. The FC2423 that is supplied with the HI98165 is designed specifically for measuring pH in cheese. From a conic tip shape in a durable 5 mm diameter stainless steel body for easy penetration into cheese without leaving a large hole to an open junction that resist clogging; the FC2423 is an ideal general-purpose pH electrode for cheese. The FC2423 connects to the HI98165 with a quick-connect, waterproof DIN connector, allowing for a secure, non-threaded attachment.\u003c\/p\u003e\n\u003cp\u003eThe HI99165 uses the stainless steel FC2423 amplified pH electrode. This specialized electrode offers numerous features that improve pH testing for cheese producers. The robust stainless steel sheath paired with the conical sensing tip allows for penetration in cheese at various points throughout the production process. An integrated temperature sensor also ensures that all pH measurements are compensated for temperature without the need for a separate temperature probe.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; align-items: center; justify-content: center; gap: 24px 48px; margin: 0 0 48px; flex-direction: row-reverse;\"\u003e\n\u003cdiv style=\"flex: 1 1 260px; max-width: 440px; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/HI99165_StainlessBodyHighlight.png\" alt=\"Stainless Steel Body\" loading=\"lazy\" style=\"display: block; max-width: 100%; height: auto; margin: 0 auto;\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 340px; min-width: 0;\"\u003e\n\u003ch4 style=\"margin-top: 0;\"\u003eStainless Steel Body\u003c\/h4\u003e\n\u003cp\u003eThe AISI 316 stainless steel body offers durability in the production facility and can withstand chloride concentrations that cause corrosion in other types of alloys.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; align-items: center; justify-content: center; gap: 24px 48px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"flex: 1 1 260px; max-width: 440px; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/HI99165_TipHighlight.png\" alt=\"conical glass tip\" loading=\"lazy\" style=\"display: block; max-width: 100%; height: auto; margin: 0 auto;\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 340px; min-width: 0;\"\u003e\n\u003ch4 style=\"margin-top: 0;\"\u003eConic Glass Tip\u003c\/h4\u003e\n\u003cp\u003eThe conical shaped tip design allows for penetration into solids, semi-solids, and emulsions for the direct measurement of pH in samples such as cheese.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-wrap: wrap; align-items: center; justify-content: center; gap: 24px 48px; margin: 0 0 48px; flex-direction: row-reverse;\"\u003e\n\u003cdiv style=\"flex: 1 1 260px; max-width: 440px; text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/HI99165_TempSensorHighlight.png\" alt=\"Temp Sensor\" loading=\"lazy\" style=\"display: block; max-width: 100%; height: auto; margin: 0 auto;\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"flex: 1 1 340px; min-width: 0;\"\u003e\n\u003ch4 style=\"margin-top: 0;\"\u003eBuilt-In Temperature Sensor\u003c\/h4\u003e\n\u003cp\u003eErrors in calibration and measurement are eliminated with the Automatic Temperature Compensation provided by the integrated temperature sensor.\u003c\/p\u003e\n\u003cp\u003eBesides being supplied with a unique pH electrode made for cheese, the HI98165 has the Hanna's unique CAL Check™ feature that alerts the user to potential problems during the calibration process. This is a very important for the food processor since it is likely that the probe will be coated with the solids found in the food product being measured. This coating can easily lead to errors in pH measurement. By comparing previous calibration data to the current calibration, the meter will inform the user, with display prompts, when the probe needs to be cleaned, replaced, or if the pH buffer might be contaminated. After calibration, the overall probe condition is displayed on screen as a percentage from 0 to 100% in increments of 10%. The probe condition is affected by both the offset and slope characteristics of the pH electrode, both of which can be found in the GLP data.\u003c\/p\u003e\n\u003cp\u003ePressing the “AutoHold” virtual key in measurement mode, the meter will freeze and automatically log a stable reading. An “out of calibration range” warning can be enabled that will alert the user when a reading is not within the bracket of calibrated pH values.\u003c\/p\u003e\n\u003cp\u003eThe log-on-demand mode allows the user to record and save up to 200 samples. The logged data, along with the associated GLP data, can then be recalled or transferred to a PC with Hanna’s HI920015 micro USB cable and HI92000 software for traceability in record keeping for specific product batches. GLP data includes date, time, calibration buffers, offset, and slope, and is directly accessible by pressing the dedicated GLP key.\u003c\/p\u003e\n\u003cp\u003eA contextual help menu based on the screen that is currently being viewed can be accessed at any time by the press of a dedicated button.\u003c\/p\u003e\n\u003cp\u003eThe high contrast, graphic LCD screen is easy to view outdoors in bright sunlight as well as in low-lit areas with the backlight.
