Yogurt is made by the fermentation of milk with live bacterial cultures. Most yogurts are inoculated with a starter culture consisting of Lactobacillus bulgaricus and Streptococcus thermophilus. Once the live culture is added, the mixture of milk and bacteria is incubated, allowing for fermentation of lactose to lactic acid. The pH of the mixture drops and becomes more acidic due to the lactic acid production; it is this reduction in pH causes the casein protein in milk to coagulate and precipitate, resulting in a yogurt-like texture.\u003c\/p\u003e\n\u003cp\u003eYogurt producers cease incubation once a specific pH level is reached. Most producers have a desired point between pH 4.0 and 4.6 in which fermentation is stopped by rapid cooling. Within this range of pH there is an ideal amount of lactic acid present for yogurt, giving it the characteristic tartness, aiding in thickening, and acting as a preservative against undesirable strains of bacteria.\u003c\/p\u003e\n\u003cp\u003eBy verifying that fermentation continues to a predetermined pH endpoint, yogurt producers can ensure their products remain consistent in terms of flavor, aroma, and texture. A deviation from the predetermined pH can lead to a reduced shelf life of yogurt or create a product that is too bitter or tart. Syneresis can also occur if fermentation is stopped too early or too late, resulting in yogurt that is respectively too alkaline or too acidic. Syneresis is the separation of liquid, in this case whey, from the milk solids. Consumers expect yogurt to remain texturally consistent, so ensuring fermentation is stopped at the appropriate pH is vital to consumer perception.\u003c\/p\u003e\n\u003cp\u003eYogurt can provide a number of challenges for the person that needs to measure pH. Yogurt is a semi-solid to slurry that has a very high solids content. This type of sample will coat the sensitive glass membrane surface and\/or clog the reference junction. The FC2133 that is supplied with the HI98164 is designed specifically for measuring pH in yogurt. From a conic tip shape for easy penetration to an open junction that resist clogging; the FC2133 is an ideal general-purpose pH electrode for yogurt products. The FC2133 connects to the HI98164 with a quick-connect, waterproof DIN connector, allowing for a secure, non-threaded attachment.\u003c\/p\u003e\n\u003cp\u003eThe FC2133 amplified pH electrode is a specialized probe that offers numerous features that improve pH testing for yogurt producers. An integrated temperature sensor allows for temperature compensated pH measurements without the need for a separate temperature probe. The probe's conical sensing bulb ensures stable calibration and measurement in semi-solids and emulsions like yogurt.\u003c\/p\u003e\n\u003cp\u003eAn integral part of any pH electrode is the reference junction. The reference junction is a part of the electrode that allows for the flow of ions located in the reference cell into the sample being tested. It is vital that this flow occurs in order to complete an electrical circuit, which ultimately determines the pH value. Any clogging of the junction will prevent completion of the circuit, resulting in readings that are erratic or constantly drifting.\u003c\/p\u003e\n\u003cp\u003eClogging of the reference junction is a common challenge faced by yogurt producers as the milk solids and proteins can easily build up on the electrode. The open junction design of the FC2133 utilizes a viscolene reference electrolyte that comes into direct contact with the yogurt sample. Without a physical junction, the electrode resists clogging and continues to provide accurate, stable readings.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: grid; grid-template-columns: repeat(auto-fit, minmax(240px, 1fr)); gap: 32px 24px; margin: 0 0 48px;\"\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: stretch; text-align: left;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/glass-body-bfa9885d.png\" alt=\"glass body\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eGlass Body\u003c\/h4\u003e\n\u003cp\u003eThe glass body of the FC2133 is chemically resistant and quick to reach thermal equilibrium, allowing for a faster, more stable response when taking pH measurements in samples that are not at ambient temperature.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: stretch; text-align: left;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/glass-conical-tip-9a18e918.png\" alt=\"conical glass tip\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eConical 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 yogurt.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex; flex-direction: column; align-items: stretch; text-align: left;\"\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1086\/9535\/5761\/files\/fc202x-open-junction.png\" alt=\"open junction reference\" loading=\"lazy\" style=\"display: block; width: auto; max-width: 100%; max-height: 220px; height: auto; margin: 0 auto 16px; object-fit: contain;\"\u003e\n\u003ch4 style=\"margin: 0 0 8px; font-size: 18px; line-height: 1.3;\"\u003eOpen Junction Reference\u003c\/h4\u003e\n\u003cp\u003eThe open junction design consists of a solid gel interface (viscolene) between the sample and internal Ag\/AgCl reference.

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.

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.
