It is extremely difficult for the Hawai‘i beef industry to compete against the concentrate-finished beef that dominates the U.S. beef industry because of our state’s lack of grain production, lack of economy of scale, and an inefficient processing segment. Nevertheless, produc­ ers continue to keep their faith in the local and emerg­ ing niche markets, looking for opportunities for mar­ keting ...

Transesterification of beef tallow and methanol is affected by many factors. Catalyst, free fatty acids, and water in beef tallow, and reaction time were investigated. Sodium hydroxide (NUOH) was a more effective catalyst than sodium methoxide (NaMeOj. NaOH and NaMeO reached their maximum activities at 0.3% and 0.5%, w/w of beef tallow, respectively. The presence of water had more negative effe...

This paper focuses on dietary approaches to control intramuscular fat deposition to increase beneficial omega-3 polyunsaturated fatty acids (PUFA) and conjugated linoleic acid content and reduce saturated fatty acids in beef. Beef lipid trans-fatty acids are considered, along with relationships between lipids in beef and colour shelf-life and sensory attributes. Ruminal lipolysis and biohydroge...

In late October 2007, an outbreak of multidrug-resistant Salmonella Newport infections affected 42 case patients in California, Arizona, Idaho, and Nevada. A case-control study implicated ground beef from one chain store. Despite detailed ground beef purchase histories--including shopper card information for several case patients--traceback efforts by both the U.S. Department of Agriculture, Fo...

Food scares have increased consumer food safety concern, particularly for beef. Traceability and food quality labels have been put in place to communicate to consumers the safety characteristics of the specially labelled beef in hopes of recovering confidence and consumption. As a consequence, production costs have increased, and thereby consumer prices as well. In this paper we develop a conce...

This experiment was conducted to evaluate the effects of saturated and unsaturated fats in starter and grower feeds on performance and carcass parts of broilers. In this experiment 288 day old broiler chicks (Ross308 strain) were used in a completely randomized design for 42 days with 8 treatments in 3 replicates and 12 chicks in each replicate. The experimental groups included: T1) control gro...

The beef sector is working towards continually improving its sustainability in order to achieve environmentally, socially and economically desirable outcomes, all of which are of increasing concern to consumers. In this context, the Global Roundtable for Sustainable Beef (GRSB) provides guidance to advance the sustainability of the beef industry, through increased stakeholder engagement and the...

Interest and questions about the quality of beef are on the rise due to heightened awareness about the marketing of beef, from procurement and processing to consumer acceptance. Belatedly, producers are now beginning to receive information about the quality of the beef they produce. Consolidations among beef marketers have resulted in better communication between marketers and producers on carc...

The microbial distribution of raw materials and beef jerky, and the effect of nisin on the growth of Bacillus cereus inoculated in beef jerky during storage, were studied. Five strains of pathogenic B. cereus were detected in beef jerky, and identified with 99.8% agreement using API CHB 50 kit. To evaluate the effect of nisin, beef jerky was inoculated with approximately 3 Log CFU/g of B. cereu...

Introduction The “Grass-fed beef ” label indicates meat that is produced by feeding forages from start to finish without any grain supplementation (USDA-AMS 2007). Many healthful aspects of grass-fed beef have been identified, including lower total fat content and higher content of omega-3 fatty acids, conjugated linoleic acids (CLA), and antioxidants as compared to feedlot-finished beef (Razmi...
