Abstract

A device (10) for determining the percent fat of a meat product such as beef or pork. The device 10 is presented in two designs, the first design uses a mechanical device in the form of a slide chart (12) and the second design employs an electronic device which is disclosed in three design configurations. The slide chart includes a stationary member (14) having a plurality of percent moisture windows (30) and percent fat windows (32) and a movable member (62) having a multiplicity of percent moisture figures (72) and percent fat figures (74). When a selected percent moisture figure (72) is located on the percent moisture window (30) the equivalent percent fat figure (74) is displayed on the percent fat window (32). The first design of the electronic device consists of a hand-held electronic calculator (90) which calculates the percent fat of the meat product when the percent moisture is known. The second design of the electronic device utilizes a percent moisture analyzer (110) that is connected, via a cable assembly (119), to an electronic calculator (94) which calculates the percent fat. The third electronic device design consists of an integrated percent moisture and fat analyzer (108).

Dependent claims

A process for determining the percent fat of a beef or pork meat product, wherein said process consists essentially of the following steps:

a) determine the percent moisture of said meat product by performing the following steps,
(1) weigh a sample of a preheated said meat product to obtain the wet weight of said meat product,
(2) subject said preheated meat product to a heat source until said meat product is substantially dry,
(3) remove said meat product from the heat source and reweigh to obtain the dry weight of said meat product, and
(4) calculate the percent moisture of said meat product by solving the following equation:
##EQU2## b) enter said percent moisture into an integrated calculating device, consisting essentially of:
(1) a keypad having a "B" key for calculating the percent fat of a beef product, a "P" key for calculating the percent fat of a pork product and ten keys 0-9 for entering the percent moisture of either the beef or pork product,
(2) a microcontroller connected to said keypad and having:
(a) a register or memory circuit means for receiving and storing the percent moisture figure of the beef or pork product as entered into the ten keys on said keypad,
(b) a firmware program 100.COPYRGT. having means for solving a beef formula and a pork formula when either the "B" key or "P" key on said keypad is depressed, wherein the equivalent percent fat of the selected meat product is determined,
(3) a display having means for receiving the output from said microcontroller, and
c) read on said device the percent fat equivalent to the entered said percent moisture.
