Institutional Meat Purchase Specifications

Institutional Meat Purchase Specifications is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Institutional Meat Purchase Specifications rather than just read about it. In short: The Institutional Meat Purchase Specifications (IMPS) are specifications for meat maintained by the Agricultural Marketing Service of the U.S. Department of Agriculture.

Key takeaways

Institutional Meat Purchase Specifications belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Institutional Meat Purchase Specifications to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Institutional Meat Purchase Specifications from memory before moving on to harder problems.

Reference excerpt

The Institutional Meat Purchase Specifications (IMPS) are specifications for meat maintained by the Agricultural Marketing Service of the U.S. Department of Agriculture. These voluntary consensus specifications are intended to standardize the procurement of meat by large-volume purchasers such as government agencies, institutions, and other food service users. Along with the identical Canadian Wholesale Meat Specifications Document, they are widely used in the wholesale meat industry, both for institutions and for retailers. Names of cuts for retail consumers are defined by the Uniform Retail Meat Identity Standards (URMIS), which is based on IMPS. They include both general requirements for meat handling and packaging as well as specific standards for specifying properties of the meat, such as its grade, state of refrigeration, fat content, portion sizes, packaging, and so on. In particular, they define and give names and reference numbers (IMPS numbers) for specific cuts of beef, lamb and mutton, veal, pork, goat, and other meat products. The Specification is divide into multiple sections:

General Requirements Quality Assurance Provisions 100 Fresh Beef 200 Fresh Lamb and Mutton 300 Fresh Veal and Calf 400 Fresh Pork 500 Cured, Cured and Smoked, Cooked Pork Products 600 Cured, Dried and Smoked Beef Products 700 Variety Meats and Edible By-Products 800 Sausage Products 11 Fresh Goat Examples of cuts:

Item No. 184D - Beef Loin, Top Sirloin Butt, Cap (IM) - This item must consist of the M. biceps femoris which is removed from Item No. 184 by cutting through the natural seams. This item is sometimes referred to as the “Coulotte”. Item No. 1401D – Pork Osso Buco, Hind Shank – This item shall be prepared from Item No. 401D. The hind shank portions shall be cut to a thickness as specified by the purchaser and approximately perpendicular to the bone length. The resulting cross section surfaces (both sides) shall display at least 75 percent exposed lean.

Examples of meat products other than cuts:

Item No. 134 - Beef Bones - This item consists of any one or combination of shank, femur, or humerus bones sawed into sections of lengths as specified by the purchaser. Marrow must be exposed on at least one end of each sawed section. Item No. 135A - Beef for Stewing - This item is as described in Item No. 135 except (unless otherwise specified) at least 85 percent, by weight, of the resulting dices must be of a size equivalent to not less than a ¾-inch (19 mm) cube or not more than a 1.5 inches (3.8 cm) cube and no individual surface must be more than 2.5 inches (6.3 cm) in length. The fat thickness of the surface and/or seam fat must not exceed ¼-inch (6 mm) at any point. Item No. 715 - Veal Sweetbreads - This item consists of the thymus glands from the neck region adjacent to the trachea. Sweetbreads are pinkish in color and shall be practically free of fat and lean. At the purchaser's option, the sweetbreads shall be blanched to remove the covering capsule and firm the tissue.

The numbers constitute the IMPS (or IMPS/NAMP) Numbering System. The Canadian Wholesale Meat Specifications Document (WMSD) uses the same numerical codes.

Worked examples

Example 1 — a first encounter with Institutional Meat Purchase Specifications

Start with the simplest possible case. Write down what Institutional Meat Purchase Specifications claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Institutional Meat Purchase Specifications before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Institutional Meat Purchase Specifications ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Institutional Meat Purchase Specifications

In research: Institutional Meat Purchase Specifications appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Institutional Meat Purchase Specifications in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Institutional Meat Purchase Specifications is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cuts of meat, Meat, so understanding it makes those chapters shorter.
In everyday life: Look for Institutional Meat Purchase Specifications outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
