Details

In the meat processing industry, the monitoring of pH is considered to be of the utmost importance due to its effect on the meat's quality factors including water binding capacity and shelf life.

Upon slaughter, biochemical processes begin to break down the meat. Glycolysis begins post-mortem, converting glycogen to lactic acid, reducing the pH of the carcass.

Depending on a number of factors such as type of animal and even breed, this decrease in pH can take anywhere from a single hour to many. It is vital to monitor pH during this phase as once the lowest pH value is reached, the pH will begin to slowly rise, indicating that decomposition has begun.

The pH value of meat influences its’ water binding capacity which directly impacts consumer qualities such as tenderness and color.

Lower pH values result in a lower water-binding capacity and lighter colors. Factors such as these can be important when considering how to efficiently produce meat products. For example, when producing dry sausages the meat must have a low water binding capacity so that it can dry evenly.

Depending on the type of the final product and the steps required to get there, pH values will vary throughout the meat processing industry.

It is imperative, regardless of the final product, that pH be maintained at a low value to prevent bacterial spoilage and comply with food safety regulations. By monitoring pH values throughout the meat production process, you can ensure the creation of consistent and safe meat products.

Meat products can provide a number of challenges for the person that needs to measure pH.

Oils and solids from the meat can coat the sensitive glass membrane surface and/or clog the reference junction.

The FC/002323 that is supplied with the HN/098163 is designed specifically for measuring pH in meat.

Design considerations include a stainless steel piercing blade around conic tip shape probe for easy penetration, an open junction that resist clogging, and a Polyvinylidene Fluoride (PVDF) food grade plastic body that is resistant to most chemicals and solvents, including sodium hypochlorite. It has high abrasion resistance, mechanical strength and resistance to ultraviolet and nuclear radiation.

PVDF is also resistant to fungal growth. The FC/002323 is an ideal general-purpose pH electrode for meat that connects to the HN/098163 with a quick-connect, waterproof DIN connector, allowing for a secure, non-threaded attachment.

FMSA compliance This pH meter meets the FDA Food Safety Modernization Act (FSMA) compliance standards.

The FC/002323 is an amplified pH electrode with a built-in temperature sensor.

This probe is designed with low temperature (LT) glass, a conical tip shape, and is housed in a food grade PVDF body with a removable, piercing stainless steel blade.

This electrode also features a unique open junction design in which there a viscolene (hard gel) electrolyte layer that is free of silver chloride (AgCl) between the sample to be measured and the internal reference cell. The open junction design resists clogging and the probe’s conical tip makes it ideal for pH measurements in meat and semi-solid food samples.

	Conical Glass Tip The conical shaped tip design allows for penetration into solids, semi-solids, and emulsions for the direct measurement of pH in food products including meat, cheese, yogurt, and milk.
	Open Junction Reference The open junction design consists of a solid gel interface (viscolene) between the sample and internal Ag/AgCl reference. This interface not only prevents silver from entering the sample, but also makes it impermeable to clogging, resulting in a fast response and stable reading.
	PVDF Body Polyvinylidene fluoride (PVDF) is a food grade plastic that is resistant to most chemicals and solvents, including sodium hypochlorite. It has high abrasion resistance, mechanical strength and resistance to ultraviolet and nuclear radiation. PVDF is also resistant to fungal growth.

Besides being supplied with a unique pH electrode for meat, the HN/098163 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.

Pressing 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.

The 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 HN/092000 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.

A 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.

The high contrast, graphic LCD screen is easy to view outdoors in bright sunlight as well as in low-lit areas with the backlight.

A combination of dedicated and virtual keys allows for easy, intuitive meter operation in a choice of languages.

The compact, durable HN/720161 carrying case is thermoformed to hold all necessary components for taking a field measurement, including the meter and electrode, beakers, buffer solutions and cleaning solutions.
