Measuring the Salt Content of Bread


The art of bread making has a rich and extensive history, with ancient roots that can be traced back at least 30,000 years. Today, the cultural and nutritional importance of bread is still significant as it continues to shape culinary identities worldwide. Generally, the process of bread making remains unchanged. Unleavened breads, such as Matzoh, are comprised of only flour and water. Upon mixing, gluten protein is formed, giving the bread structure and elasticity. After the dough is kneaded, it is baked immediately and results in a thin “ flat bread”. In comparison, leavened bread is that which rises during the baking process due to the addition of a leavening agent.

Monitoring Moisture Content in Spices


Over the past few years, with the popularity of cooking shows, there has been an increasing trend of people experimenting more with flavors and tastes. One way that people experiment in the kitchen is through the use of spices and herbs. Considering the International Organization for Standardization (ISO) identifies over 100 varieties of herbs and spices, there are many different options for flavor combinations.

Determination of Protein Content in Milk through Total Kjeldahl Nitrogen Analysis


Proteins are macromolecules that play a crucial role in nutritional growth and development. These large biological molecules contain at least one long chain of amino acid residues and are responsible for a multitude of biological functions, including DNA
replication and repair, catalyzing metabolic reactions, and providing structure and communication in and between cells. The digestive breakdown of proteins into amino acids provides an important source of fuel and dietary nitrogen. Milk naturally contains a number of key nutrients, including protein, which is beneficial to humans regardless of their age. Globally, milk is a commonly consumed food product that, due to its high nutrient composition, is regarded as highly beneficial for growth. In cow and sheep milk the percent protein can range from 3.3% to 5.8%.

Mini Automatic Titrator for Dairy

We’re pleased to announce the release of a new mini automatic titrator designed specifically for the dairy industry.

The new titrator, HI 84529, is designed specifically for testing the acidity levels and pH in dairy products.

It features a high precision piston dosing system with dynamic dosing and compact, space saving footprint.  It also feature automatic stirrer speed control, a graphic mode with exportable data and a Good Laboratory Practices (GLP) feature which allows users to view calibration data.

Hanna Instruments manufactures a variety of analytical instrumentation for the food and beverage industry, including juice meters, dairy meters, wine meters and more.
Hanna’s new mini titrator is available through any of our 40 international locations.  These offices provide Hanna customers with local service, support and training and are part of Hanna’s goal to provide an exceptional customer experience.

Hanna Instruments releases industry first Titrator with 40,000 step dosing pump

Hanna Instruments is pleased to announce the release of two new automatic titration systems utilizing an industry first 40,000 step dosing pump.

The HI 903 Karl Fischer Volumetric Titrator and the HI 902C2 two channel Potentiometric Titrators are the latest products in the Hanna family of scientific analytical instrumentation.  Designed to streamline and simplify the titration process, these two units offer an excellent balance of features, accuracy and price.

Both titrators offer Hanna’s unique “Clip LockTM” Exchangeable Burette system for quickly and easily swapping burettes with reagents used to perform different titrations.  The Clip Lock system prevents cross contamination since a separate burette can be used for each titrant.  Having the ability to swap burettes also reduces the time it takes to change reagents for a separate titration since the titrant does not have to be purged from the burette.
