This study optimized material use for making pressed pork hams (PPHs) using the least cost formulation program. Based on protein (P) content, different fat (2.5, 3.0, and 4.0P) and moisture (4.0P + 10, 4.0P + 15, 4.0P + 20, and 4.0P + 25) ratios were applied to make PPHs. Total expressible fluid, cooking loss, and purge loss were highest in PPHs formulated with 4.0P + 25 water (P < 0.05). With increasing fat ratio, lightness increased, but redness decreased (P < 0.05). Lipid oxidation was not affected by moisture ratio (P > 0.05). Hardness, gumminess, and adhesiveness decreased with increased fat and moisture (P < 0.05). PPH cost was reduced by fat and moisture. These results suggest that the formulations with 4.0P + 15 moisture, regardless of fat ratio, are recommended for PPHs due to their moderate cost and quality characteristics. In addition, greater cost savings can be expected by further subdividing raw material criteria for industrial applications.

Feasibility and assessment of self-reported dietary recalls among newly diagnosed multiple sclerosis: a quasi-experimental pilot study.

Background: Individuals who are newly diagnosed with clinically isolated syndrome (CIS) or relapsing-remitting multiple sclerosis (RRMS) may choose not to undergo disease-modifying therapies (DMTs) due to concerns about expenses or potential adverse effects. Thus, many individuals will opt for alternative therapies, such as dietary modifications. Among these dietary approaches, the modified Paleolithic elimination diet has shown promise for improving MS-related symptoms; however, restriction of certain food groups can lead to inadequate intake of nutrients.

High internal phase emulsions (HIPEs) are promising techniques that can replace saturated fat in food without reducing the product's texture, sensory attributes, water-holding capacity, and cooking loss. In the current investigation, 100% pork back fat was replaced by HIPEs formed with lentil protein isolate (LPI) in Bologna sausages. HIPEs were prepared by 25% LPI dispersion (2, 4, 6, and 8%, w/w) and 75% (w/w) soybean oil.

In order to cope with the limited supply of feed for global animal production, there is a pressing need to explore alternative feed resources. Orange pulp, a by-product of agriculture and industry, has shown potential to positively or neutrally impact pig productive performance when included in their diet. However, there is a lack of research on the effects of fermented navel orange pulp (FNOP) on pig growth and productive performance.

The investigation of the mechanism underlying the impact of biological soft tissue sample preparation methods on laser-induced breakdown spectroscopy (LIBS) signals can enhance the stability of LIBS signals. Our study focused on four specific preparation methods applied to pork samples: rapid freezing, fresh slicing, drying, and pressing. The influence of various preparation techniques on the signal-to-noise ratio and fluctuation of Ca, Na, Mg, and CN bands within the sample spectra was assessed.

The carbon footprint of pork production is a pressing concern due to the industry's significant greenhouse gas emissions. It is crucial to achieve low-carbon development and carbon neutrality in pork production. Thus, this paper reviewed the recent studies about various sources of carbon emissions throughout the current pork production chain; feed production, processing, and manure management are the major sources of carbon emissions.
