1、Designation: F2925 11Standard Specification forTenderness Marketing Claims Associated with Meat CutsDerived from Beef1This standard is issued under the fixed designation F2925; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the ye
2、ar of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers requirements for incorporatinga tenderness marketing claim to finished labeling, adver
3、tise-ments, or promotions, or a combination thereof, associatedwith beef cuts to distinguish product value in the marketplace.1.2 The marketing claim requirements in this specificationcan be used by all parties interested in highlighting productionand marketing practices of tender beef muscles/cuts
4、in finishedlabeling, advertisements, or promotions, or a combinationthereof, to distinguish their products in the marketplace. Atenderness marketing claim standard for beef cuts facilitatescommunication by enhancing the understanding of finishedproduct expectations among producers, processors, and c
5、on-sumers.1.3 Beef cuts being considered for this tenderness marketingclaim will be certified through third party auditing activities.Firms seeking these services must adhere to the standardpractices associated with this specification as recognized by thecertifying body.1.4 The values stated in SI u
6、nits are to be regarded asstandard. No other units of measurement are included in thisstandard.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health pr

Claim Considerations4.1 Minimum Tenderness Threshold Value (MTTV)AMTTV for WBSF an
16、d SSF of 4.4 and 20.0 kg (43.1 and 196.1N, SI units of specification for force, Newton), respectively,is representative of instrumental and sensory research con-ducted with tender beef (1-3).3Moreover, a 0.5-kg (5.0-N)difference in WBSF (4.6 kg (46.0-N) for SSF) represents thedifference in WBSF forc
17、e that the average consumer can detectwhen consuming meat at home (4). Additionally, surveysconducted with regard to tenderness indicate that this MTTVwill accommodate many cattle in our current national popula-tion (5).4.1.1 Relationship to LD:4.1.1.1 If the carcass LD is directly measured or predi
18、ctedby a recognized methodology or technology or both and the LDmeets the MTTV, then the tensor fascia latae, rectus femoris,vastus medialis, psoas major, infraspinatus, spinalis dorsi, teresmajor, and serratus ventralis muscles will also qualify as beingtender without having to be measured.4.1.1.2
19、All other muscles should not qualify throughmeasurement/prediction of the LD as being tender unlessdirectly measured and meet the requirement on their ownmerits.4.1.2 Meat Cuts Derived from Qualifying Muscles:4.1.2.1 Meat cuts considered for the tender claim shall befabricated in a manner such that
20、the claim is substantiated bylean tissue derived from qualifying muscles being 90 % byweight of the total lean content of the meat cut. Moreover,guidelines for appropriate preparation and thermal process foreach covered meat cut shall be made available to the end user.4.1.2.2 Examples:(1) IMPS Item
21、No. 191ABeef loin, tenderloin, butt,defatted.(2) IMPS Item No. 1185BBeef loin, bottom sirloin butt,ball tip steak.4.1.3 Inherently TenderOnly inherently tender meat prod-ucts shall qualify. Inherently tender meat is that which has notbeen subjected to further processes not typically used duringthe c
22、onversion of muscle to meat. Examples of these areenhancement through marination (injection and tumbling),mechanical tenderization (blade or needle), and chemicaltenderization. Inherent processes include, but are not limitedto, electrical stimulation (during harvest), carcass suspensiontechniques, a
23、nd aging (carcass, primal, or subprimal, or acombination thereof).5. Claim Requirements5.1 Certified TenderThis claim applies to qualifying meatcuts (4.1.2) from the beef carcass that have not been enhancedor processed to be tender as described in 4.1.3. The currentrecognized technologies for this m
24、easurement are the WBSFand SSF devices that meet the MTTV of 4.4 and 20.0 kg (43.1and 196.1 N), respectively, on meat cooked to a targeted 71Cusing American Meat Science Association (AMSA) researchguidelines (6). The number of days postmortem for thismeasurement will be documented for validation pur
25、poses.5.2 Certified Very TenderThis claim applies to qualifyingmeat cuts (4.1.2) from the beef carcass that have not beenenhanced or processed to be tender and exceeds the MTTV byat least 0.5 kg (5.0 N) for WBSF or 4.6 kg (46.0 N) for SSF.6. Product Marking6.1 When conducted in accordance with this
26、practice, theproducts meeting the requirements can be claimed to be“certified tender” or “certified very tender” if reference to thispractice is made and labeling approval is granted from theappropriate food regulatory authority(ies).7.
