چکیده

No significant differences were found in surface microflora of county-cured hams covered with stockinettes, barrier bags, or a coating of paraffin wax during aging, except for a reduction in mold growth on waxed hams. The incidence of Clostridium spp. was lost in all treatments. Micrococcus spp. and Streptococcus spp. were the most common contaminants, but caused no apparent spoilage problem in any treatment.

Genetic markers for the production of US country hams.

The objective of this study was to determine the effect of candidate genes on processing quality traits of US country hams. A total of 321 fresh hams of unknown breed and sex were examined and data on quality and physical traits were collected. The hams were then processed following typical US commercial dry-curing procedures for ham and data on additional traits were collected from the cured h...

Compositional Modeling of Wax Formation in Petroleum Mixtures

Heavy organics deposition is a common problem in oil industry, especially in oil production, transportation and processing. Wax or solid paraffin series are examples of heavy organics that deposit. Precipitation and crystallization of wax causes major difficulties in different processes. Based on multi-solid theory, a basic model is modified in this paper for wax precipitation in different oils...

The effects of a step-up ractopamine feeding program on growth performance and low-sodium ham characteristics of purebred Berkshire pigs1

Objectives were to test the effect of a lowsodium curing solution on processing characteristics of hams from purebred Berkshire pigs that were fed a step-up ractopamine HCl (RAC) feeding program or a negative control diet. Sixty pairs (n = 120) of hams were selected from two blocks of purebred Berkshire pigs (n = 200) that were fed either a control diet or 7.4 mg of ractopamine/ kg of diet for ...

Appearance , fl avor , and texture attributes of pig dry - cured hams have a complex polygenic genomic architecture 1

The infl uence that the genetics of species used as food sources has on the human perception of sensory attributes has been rarely addressed in previous studies. Dry-cured hams are high-quality highly appreciated pork products obtained by salting, curing, drying, and aging processes. We performed a QTL scan for 17 sensory attributes (including appearance, taste, fl avor, and texture) and the ov...
