Beef imports in Chile have increase annually by close to 10% in the past 10 years, threatening the national industry. Understanding the importance of different attributes may help guide a strategy for the local beef industry. Thus, the goal of the study was to identify which attributes observable at the point of sale influence the beef buying process. The sample was a set of 406 price observations, search attributes (intrinsic and extrinsic cues), and credence attributes of differentiated beef. The study was conducted in 15 counties in the Metropolitana region in Chile, and the results indicated that among differentiated beef, the highest valued attributes were low fat and natural. In addition, Angus and Wagyu beef, breeds associated by consumers with increased tenderness and flavor, were highly valued. Finally, processed beef products (portioned, marinated, or seasoned) were more valued than unprocessed products. An important and unexpected result is that highlighting Chile as the country of origin is a negatively valued attribute.

Background: Muscle and adipose tissue are the most critical indicators of beef quality, and their development and function are regulated by noncoding RNAs (ncRNAs). However, the differential regulatory mechanisms of ncRNAs in muscle and adipose tissue remain unclear.
Results: In this study, 2,343 differentially expressed mRNAs (DEMs), 235 differentially expressed lncRNAs (DELs), 95 differentially expressed circRNAs (DECs) and 54 differentially expressed miRNAs (DEmiRs) were identified in longissimus dorsi muscle (LD), subcutaneous fat (SF) and perirenal fat (VF) in Qinchuan beef cattle.

Alternative meat production technologies offer the potential to alleviate many of the ethical, environmental, and public health concerns associated with conventional meat production. Cultured meat produced using cell culture technology promises to become a viable alternative to animal-raised meat for the future of the food industry. The process of cultured meat production relies on cell sources harvested from livestock such as bovine, swine, and chicken.

This study aimed to identify mRNA isoforms that were expressed differently in the muscle tissue of Nellore cattle based on their intramuscular fatty acid profile. Forty-eight young bulls were used to quantify beef fatty acids (FA) and perform RNA sequencing analysis. The young bulls were divided into three different groups based on quantifying FA using k-means analysis.

Yaks are a rare and unique animal species inhabiting the Qinghai-Tibet Plateau; they are renowned for their remarkable ability to thrive in harsh environments. Milk-derived exosomes, tiny vesicles containing various biological molecules, play crucial roles in numerous pathological and physiological processes, including cell growth, development, and immune regulation. This study delved into the microRNA expression profiles of yak milk-derived exosomes collected from both high- and low-altitude populations using small RNA sequencing.

For cultured meat to effectively replace traditional meat, it is essential to develop scaffolds that replicate key attributes of real meat, such as taste, nutrition, flavor, and texture. However, one of the significant challenges in replicating meat characteristics with scaffolds lies in the considerable gap between the stiffness preferred by cells and the textural properties desired by humans. To address this issue, we focused on the microscale environment conducive to cell growth and the macro-scale properties favored by humans.
