AI Article Synopsis

Article Abstract

To make meat adulteration detection systems faster, simpler and more efficient, we established a duck-derived meat rapid detection Recombinase Polymerase Amplification (dRPA) method by using interleukin 2 (IL-2) from nuclear genomic DNA as the target gene to design specific primers. We tested the dRPA detection system by comparing its sensitivity and specificity using real-time fluorescent PCR technology. By adjusting the ratio of reagents, this method shortens the time of DNA extraction and visualizes results in combination with colloidal gold immunoassay strips. Our results demonstrate that this dRPA method could specifically detect duck-derived components with a sensitivity of up to 23 copies/μL and the accuracy of the results is consistent with real-time fluorescent PCR. Additionally, dRPA can detect at least 1% of the duck meat content by mixing beef and mutton with duck meat in different proportions, which was verified by spot-check market samples. These results can be visualized with colloidal gold immunoassay strips with the same accuracy as real-time fluorescent RPA. dRPA can complete detection within 30 min, which shortens existing detection time and quickly visualizes the detection results on-site. This lays the groundwork for future large-scale standardized duck origin detection.

Perforated imprinting on high moisture meat analogue confers long range mechanical anisotropy resembling meat cuts.

NPJ Sci Food

December 2024

Department of Physiology, The Institute for Digital Medicine (WisDM), Yong Loo Lin School of Medicine, National University of Singapore, Singapore, 117593, Singapore.

Meat cuts, when cooked and masticated, separate into fibrous structures because of the long-range mechanical anisotropy (LMA) exhibited by muscle fascicles, which is not fully recapitulated in alternative proteins produced using molecular alignment technology like high moisture extrusion. We have developed a scalable perforated micro-imprinting technology to greatly enhance LMA in high moisture meat analogue (HMMA). By imprinting 1 mm thick HMMA sheets with perforated patterns (optimized by AI), we observed up to 5 × more anisotropic separation of fibrous structures in a one-dimensional pulling LMA analysis, to match the fibrousness of the cooked chicken breast, duck breast, pork loin and beef loin.

Duck egg white jelly, a protein-rich, alkali-induced gel, mirrors preserved duck egg white in appearance and properties, offering easier storage and utility, especially when excess egg white is available. This research focuses on incorporating duck egg white jelly into emulsified meat snacks to enhance texture while reducing the phosphate content. This study suggests that adding phosphate and duck egg white jelly increases raw meat paste pH, affecting its viscosity.

Data-driven insights into pre-slaughter mortality: Machine learning for predicting high dead on arrival in meat-type ducks.

Research Center for Veterinary Biosciences and Veterinary Public Health, Faculty of Veterinary Medicine, Chiang Mai University, Chiang Mai 50100, Thailand; Faculty of Veterinary Medicine, Chiang Mai University, Chiang Mai 50100, Thailand. Electronic address:

Dead on arrival (DOA) refers to animals, particularly poultry, that die during the pre-slaughter phase. Elevated rates of DOA frequently signify substandard welfare conditions and might stem from multiple causes, resulting in diminished productivity and economic losses. This study included 18,643 truckload entries from 45 farms, encompassing a total of 23,191,809 meat-type ducks sent to a single slaughterhouse in Eastern Thailand between January 2019 and December 2023.

Transcriptome analysis reveals the regulatory mechanism of myofiber development in male and female black Muscovy duck at different ages.

Introduction: Sexual dimorphism in Muscovy ducks results in substantial differences in muscle development potential between males and females, leading to significant variations in growth rates and body weights throughout their development.

Methods: This study aimed to investigate the regulatory mechanisms underlying the differences in muscle development between genders in black Muscovy ducks, we analyzed the phenotypic characteristics and transcriptome profiles of breast muscles in male and female black Muscovy ducks at different developmental stages (postnatal days 28, 42, and 70).

Results: In the analysis of tissue physical morphology, the results showed that females exhibit larger myofiber diameters and lower myofiber densities compared to males at postnatal day 42 ( < 0.

Residual feed intake (RFI) has recently gained attention as a key indicator of feed efficiency in poultry. In this study, 800 slow-growing ducks with similar initial body weights were reared in an experimental facility until they were culled at 42 d of age. Thirty high RFI (HRFI) and 30 low RFI (LRFI) birds were selected to evaluate their growth performance, carcass characteristics, and muscle development.
