Before the development of the DSC compact digital fat analyzer, sanitarians and meat inspectors used the Hobart F101 Fat Percentage Measuring Kit extensively. This portable field kit was used to rapidly estimate fat content of meat, which was followed by taking a legal sample for further analysis if necessary.
The original Model F100 field kit was patented in July 1960 and introduced to the regulatory community shortly thereafter. The F100 had an integrated timer and cooking element to help separate the moisture and fat from the protein. A newer model F101 separates these two components and improved the configuration of the exhaust for better heat dissipation. The F101 is still marketed and available today. The kit weighs 20 pounds and was designed to be completely portable. The glass equipment was standard and easily replaceable, thereby making it an excellent field instrument.
The F101 kit was designed to determine the percentage of fat content of a 2-ounce (56.7 g) sample of ground beef containing from 10–40% fat. Each test takes 15 minutes and is accurate within ±1%. Although not indicated by the manufacturer’s specifications, sanitarians also used the kit to determine the fat content of sausage and other meat mixtures such as meatloaf and meatballs; however, these samples were tested for screening purposes only.
The Hobart Electric Manufacturing Company was founded in 1897 in Troy, Ohio, by Clarence Charles Hobart. At that time, the company manufactured electric dynamos and motors. In 1903, the company began making electric coffee mills and by 1905, had expanded its product line to include the first electric meat chopper. In 1913, The Hobart Electric Manufacturing Company was reorganized, and its name changed to The Hobart Manufacturing Company. In 1974 the name changed to Hobart Corporation. Since 1999, the Hobart brand has been part of ITW Food Equipment Group, LLC, a subsidiary of Illinois Tool Works, and remains a leading manufacturer of commercial food preparation equipment, commercial dishwashers, and weighing and wrapping equipment. Hobart also is one of the major contributors and participators in NSF food equipment standards development.
