To assess the effects of dietary conjugated linoleic acid (CLA) on performance, slaughter and meat quality, 100 Danish barrows were fed diets containing 0.5% sunflower oil (control) and 0.5% CLA from 40 kg live weight until slaughter at either 100 or 130 kg live weight. Plasma total cholesterol (P=0.006) and HDL-cholesterol (P=0.021) was reduced, and plasma FFA-concentration increased (P=0.06) in pigs fed CLA. CLA supplementation improved (P=0.01) the feed utilisation by 4.7% and 4.3% for pigs slaughtered at 100 and 130 kg, respectively. Daily gain tended (P=0.06) to increase with the CLA-treatment (1.236 versus 1.194 kg for CLA- and control, respectively). Dietary treatments had no effects on slaughter- (meat percentage and backfat thickness) and meat quality responses (pH, temperature and water holding capacity). CLA tended (P=0.09) to reduce the intramuscular cholesterol, but had no influence on the total content of intramuscular fat.

Quinoa polysaccharides have attracted significant research interest in recent years due to their diverse biological activities, including antiviral, anti-inflammatory, antioxidant, and immunoregulatory properties. These attributes align with the growing global demand for natural, functional food ingredients, positioning quinoa polysaccharides as a valuable resource in food science and technology. This review presents an overview of the various bioactivities of quinoa polysaccharides, critically evaluates the methods used for their extraction and purification, describes their structural characteristics, and discusses their practical applications across multiple areas within the food industry, including food additives, meat products, health foods, and innovative food packaging.

This study was aim to investigate the effects of lipoic acid (ALA) on performance, meat quality, serum biochemistry and antioxidant function of broilers under heat stress (HS). Two hundred1-day-old Cobb broilers were randomly divided into four treatment groups and each treatment consisted of 4 replicates of 10 broilers each. The treatment group adopts a 2 × 2 two-factor setting, which is divided into two diets (basic diet or 250 mg/kg ALA diet) and two temperatures (24 ± 1℃ or 33 ± 1℃).

The primary product currently sold from is foie gras, with limited research conducted on the processing of meat, which consequently restricts its added value. Therefore, the objective of this research is to develop a processing technique for reconstituted goose cutlets using meat as the main ingredient, aiming for a compact structure and intact shape after frying. The study examined the effects of compound enzyme quantity, tumbling duration, and molding time on the quality of the reconstituted goose cutlets, utilizing bonding strength, cooking loss rate, color, chewability, adhesiveness, and sensory evaluation as key metrics.

Sheep and goat meat products are becoming increasingly popular among consumers due to their unique flavor derived from intramuscular fat (IMF), which contributes to formation of the distinctive odor. However, there is currently a dearth of reviews on the impact of IMF on the flavor of sheep and goat meat. The present review aims to discuss the relationships between IMF and flavor through lipid composition and fatty acid (FA) distribution, provide an overview of characteristic flavor compounds affecting the flavor of sheep and goat meat, and shed light on the impacts of pre-mortem and post-mortem factors on meat flavor attributed to changes in FAs and flavor compounds.

As global demand for plant-based foods increases due to their nutritional and environmental benefits, young jackfruit () is emerging as a promising meat alternative. This study evaluates the effects of heat treatments-specifically blanching for 5 min and boiling for 15, 30, and 45 min-on the quality and sensory attributes of jackfruit-based meatballs. The results indicate consistent color values ( , , and ) across the samples, with values ranging from 53.
