AI Article Synopsis

  • A study analyzed 98 fresh mutton samples from various provinces in China to evaluate tenderness using Fourier transform near infrared (FT-NIR) spectroscopy.
  • A partial least squares (PLS) algorithm was employed to correlate the shear force values (a measure of tenderness) obtained from a texture machine with the FT-NIR spectra.
  • Results showed that FT-NIR spectroscopy can effectively predict mutton tenderness, with a calibration correlation coefficient (r²) of 86.2% and strong agreement between measured and predicted values.

Article Abstract

Ninety eight representative fresh mutton samples from Neimeng, Ningxia, Gansu, Xinjiang province were selected for this study, the nondestructive measurement of the fresh mutton tenderness by Fourier transform near infrared (FT-NIR) spectroscopy was discussed. Partial least squares(PLS) algorithm was used to build the model between the shear force value of the fresh mutton tenderness measured by the texture machine and the FT-NIR spectra. The influence of different processing method of spectra, factors and wave regions on the determination coefficients (r2), root mean square error of cross validation (RMSECV) and root mean square error of prediction (RMSEP) was studied. The result showed that the shear force value of ninety eight representative fresh mutton samples was 1.673-6.631 kg, and the shear force value above 75% samples was 2-5 kg, almost covering the fresh mutton tenderness of our country's sheep, the r2 of the calibration could reach 86.2% and the RMSECV was up to 0. 445 in the wave number range 11 995-5 446 cm(-1) and 4 601-4 246 cm(-1) with vector normalization when the PLS factors was ten. The correlation coefficient(R), RMSEP and average bias between value measured by the texture machine and predicted value of model based on validation samples were 0.87, 0.524 and 0.385 respectively. The result indicates that FT-NIR spectroscopy is capable of predicting tenderness value of fresh mutton.

Article Synopsis
  • - The study assesses pathogenic bacteria prevalence in raw livestock meat (pork, beef, mutton) in China for 2021, with a focus on antimicrobial resistance (AMR) to inform public health and food safety practices.
  • - Out of 2,515 meat samples, contamination rates were highest in pork for certain pathogens, with specific prevalence noted in chilled and frozen meat compared to fresh.
  • - The study found high overall resistance rates in bacteria isolated from meat, with ampicillin and tetracycline showing the most significant resistance among the tested antimicrobial agents.

Electrostatically-enhanced two-stage low-temperature tempering: Effects on the quality of frozen tan mutton.

Food Chem X

College of Food Science and Engineering, Ningxia University, Yinchuan, Ningxia 750021, China.

The two-stage low-temperature tempering (TLT) and TLT assisted by electrostatic fields (TLT-1500/2000/2500/3000) were developed to investigate their effects on the quality of frozen Tan mutton. The results demonstrated that both TLT and TLT-1500/2000/2500/3000 significantly ( < 0.05) enhanced the tempering rate compared to refrigerator tempering (4 °C, RT).

This study aims to explore the link between dietary habits and adverse pregnancy outcomes (APOs), including preterm birth (PB), preeclampsia (PE), gestational diabetes mellitus (GDM), fetal growth restriction (FGR), and spontaneous abortion (SA) through two-sample Mendelian randomization (MR). We accessed publicly available genome-wide association studies' (GWAS) summary statistics for dietary habits and APOs, respectively. We used five MR methods to synthesize MR estimates across genetic instruments.

Background: The relationship between dietary factors and hernias is currently unclear.

Methods: The UK Biobank was used to extract dietary factors that were used as exposures, including intake of alcohol, non-oily fish, beef, fresh fruit, oily fish, salad/raw vegetables, dried fruit, coffee, cereal, salt, tea, water, cooked vegetables, cheese, Lamb/mutton, pork, poultry, processed meat, and bread. The FinnGen biobank was used to obtain GWAS data on hernias as outcomes.
