Dry-aged beef quality with the addition of Mucor flavus - Sensory, chemosensory and fatty acid analysis.

Dry-aged beef is a premium product known for its unique taste and aroma. These characteristics are thought to partially depend on the composition of the microorganisms present on the meat surface during ageing. Recently several attempts to standardise this process were made.

Cold adapted and closely related mucoraceae species colonise dry-aged beef (DAB).

The dry ageing is a historically relevant method of meat preservation, now used as a way to produce the dry-aged beef (DAB) known for its pronounced flavour. Partially responsible for the taste of the DAB may be various microorganisms that grow on the surface of the meat. Historically, the fungal species colonising the DAB were described as members of the genera Thamnidium and Mucor.

Fungal Biostarter Effect on the Quality of Dry-Aged Beef.

Meat aging is a process consisting of its storage in specific conditions which leads to an increase in its organoleptic qualities. The most common method of meat aging is the wet vacuum-bag based method, whereas the traditional method, called dry-aging, involves keeping meat at a low temperature for an extended time. However, this process is characterized by low repeatability of the results.

The sarcoplasmic protein profile of breast muscle in Turkeys in response to different dietary ratios of limiting amino acids and Clostridium perfringens-induced inflammation.

In this study, the effects of the Arginine/Lysine (Arg/Lys) ratio in low- and high-methionine (Met) diets on the sarcoplasmic protein profile of breast muscles from turkeys reared under optimal or challenge (Clostridium perfringens infection) conditions were determined. One-day-old Hybrid Converter female turkey poults (216 in total) obtained from a commercial hatchery on hatching day, and on the basis of their average initial body weight were randomly allocated to 12 pens (4 m each; 2.0 m × 2.

Applications of Biosensors for Meat Quality Evaluations.

The aim of this study was to apply biosensors in the assessment of meat quality. The research was carried out on 20 samples of the muscle obtained from pork of Polish Landrace and Polish Large White hybrids of fattening pigs. In the samples, 48 h after slaughter pH values, color parameters in the CIE system (L* a* b*), the volume of natural drip loss and intramuscular fat content were measured.

Effect of Heat Treatment by the Sous-Vide Method on the Quality of Poultry Meat.

An increase in the consumption of poultry meat has been observed due to its availability, nutritional value, and delicate flavor. These characteristics make it possible to prepare, with the use of spices and other additives, many different dishes and products for increasingly demanding consumers. The sous-vide technique is increasingly being used to give new sensory attributes to dishes in gastronomy.

Effect of Herbal Addition on the Microbiological, Oxidative Stability and Sensory Quality of Minced Poultry Meat.

The study aimed to assess the effect of herbal additions with antioxidant properties (pepper, thyme and oregano) on the microbiological and oxidative stability as well as the sensory quality of minced poultry meat. Meatballs treatments without additives and treatments with the addition of three types of spices in two forms-dry spices and industrial extracts were examined. Popular seasoning additives of oregano (), thyme () and black pepper () at 0.

Acceptance of Fresh Pasta with β-Glucan Addition: Expected Versus Perceived Liking.

The aim was to recognize the effect of oat β-glucan fiber addition on expected and perceived liking of fresh pasta. Durum wheat semolina was enriched with oat β-glucan fiber in proportions: 0, 4, 8, 12 and 16% in relation to wheat flour. The evaluation of pasta samples was carried out by a group of 150 consumers and 10 panelists.

The effects on the quality of poultry meat of supplementing feed with zinc-methionine complex.

Background: Recently, an increase in the consumption of poultry meat has been observed Worldwide. This is related to the growing production of this kind of meat. Intensive poultry meat production affects the level of bird welfare and meat quality.

The effect of vegetable and spice addition on the acrylamide content and antioxidant activity of innovative cereal products.

The aim of the work was to assess the impact of vegetable and spice addition on the acrylamide content and antioxidant activity of extruded cereal crisps. The foods were based on grain ingredients, such as brown rice, whole grain flour, wheat bran, with different vegetables. Products from one group contained green vegetables, such as broccoli and zucchini; garlic was included as a flavour additive (0.

The effect of inulin supply to high-fat diet rich in saturated fatty acids on pork quality and profile of sarcoplasmic protein in meat exudate.

The aim of the study was to evaluate the influence of inulin supply to high-fat diet rich in saturated fatty acids (SFA) on pork quality and profile of sarcoplasmic protein in drip loss. At 50 days of age, twenty cross-bred pigs (gilts) were randomly allotted to four groups: the control (C) group fed a standard diet, and three experimental (D1, D2 and D3) groups fed a high-fat diet rich in SFA. Moreover, pigs from the groups D2 and D3 consumed an extra inulin supply (7% of daily feed intake) from 85 to 120 days of age (for 5 weeks) and from 50 to 120 days of age (for 10 weeks) respectively.

Formation of heterocyclic aromatic amines in relation to pork quality and heat treatment parameters.

The aim of the research was to analyze the influence of chemical composition, technological and sensory pork quality on the formation of heterocyclic aromatic amines (HAAs) after heat treatment. Material for analysis was taken from 36 samples of pork with different ultimate pH. The results showed that the studied meat was characterized by variation in chemical composition, especially in precursors of HAAs.

Sarcoplasmic Protein Profile from Drip Loss in Relation to Pork Quality.

The aim of this research was to correlate the sarcoplasmic protein profile of the natural drip loss of muscle with the technological and sensory quality of pork meat. Material for analysis was taken from 14 PenArLan pigs. Simple analysis of relationships between the test protein and meat quality traits showed that they adopt a range of from -0.

Relationship between sensory attributes and volatile compounds of polish dry-cured loin.

Objective: The aim of this work was to determine the relationship between objective sensory descriptors and volatile flavour compound composition of Polish traditional dry-cured loin.

Methods: The volatile compounds were investigated by using solid phase microextraction (SPME) and gas chromatography-mass spectrometry (GC-MS). For sensory assessment, the quantitative descriptive analysis (QDA) method was used.
