Utjecaj dodatka praha sjemenki tara gume (Caesalpinia spinosa) na oksidacijsku stabilnost i boju svinjskog mesa tijekom hladnog skladištenja

The eff ect of dried pods of Caesalpinia spinosa, known as tara, on pH, cooking loss, lipid oxidation, colour stability and texture of model meat systems stored at 4 °C for 21 days was investigated. Tara pod powder showing a potential antioxidant activity was added at 0.02, 0.04 and 0.08 % (by mass) directly to the pork batt er and compared with a synthetic antioxidant, butylated hydroxyanisole (BHA) and control (no added antioxidants). The addition of tara pod powder at 0.02 % was as effective as BHA (0.02 %) in retarding lipid oxidation in pork products during storage. Results showed that redness increased after the addition of tara pod powder. Specifically, 0.02 % of tara pod powder was effective in keeping the red colour of meat batter stored under illumination at 4 °C for 48 h. Hardness of pork products was the lowest in samples manufactured with tara pod powder compared with control. Results highlight the potential of using tara pod powder as natural functional ingredient in the development of pork products with enhanced quality and shelf life.U radu je ispitan utjecaj dodatka sušenih sjemenki tara gume (Caesalpinia spinosa), na pH-vrijednost, kalo kuhanja, oksidaciju lipida, stabilnost boje i teksturu svinjskog mesa tijekom 21 dana skladištenja na temperaturi od 4 °C. Smjesi mljevenog mesa dodano je 0,02; 0,04 i 0,08 % praha sjemenki tara gume, te je njihova antioksidacijska aktivnost uspoređena sa sintetskim antioksidansom, butiliranim hidroksianisolom (BHA), i kontrolnim uzorkom (bez dodatka antioksidansa). Utvrđeno je da je dodatak 0,02 % praha tara gume učinkovito usporio oksidaciju lipida tijekom skladištenja, kao i BHA (0,02 %). Rezultati pokazuju da se dodatkom praha tara gume pojačao intenzitet crvene boje mesa. Uzorak mesa s dodatkom 0,02 % tara gume zadržao je crvenu boju nakon izlaganja svjetlu tijekom 48 sati pri 4 °C. U usporedbi s kontrolnim uzorkom, uzorci s dodatkom praha tara gume imali su mekšu teksturu. Dobiveni rezultati potvrđuju mogućnost primjene praha tara gume kao prirodnog funkcionalnog sastojka za poboljšanje kakvoće i produljenje roka trajanja proizvoda od svinjskog mesa

Effect of Cornelian Cherry (Cornus mas L.) Juice on Selected Quality Properties of Beef Burgers

Bioactive compounds of plant origin are becoming increasingly popular as food ingredients with a beneficial impact on human health. Therefore, the present study aimed to investigate the possibility of using different doses (0.5 g–1.5 g) of cornelian cherry juice (CCJ) as a functional additive in the production of beef burgers. Results of the experiment showed CCJ addition to cause high acidification of the meat emulsion and to decrease meat production yield was unbeneficial from the economic point of view. In contrast, the CCJ was highly effective in retarding lipid oxidation in beef burgers during storage wherein even a dose of 0.5 g CCJ resulted in beneficial inhibition of oxidative changes and at the same time had no negative effect on the sensory characteristics of beef burgers. CCJ can be applied in the meat industry to develop novel products; however, future research is needed regarding its acidifying properties

Microbiological Safety and Organoleptic Quality of Homogenized Sausages Manufactured with Commercial Functional Additives

The aim of the study was to compare the microbiological safety and sensory quality of meat products manufactured with commercial functional additives. Four functional additives (AFX, AE100, PANA4, FPRX) were used in industrial conditions in the production of homogenized meat products (thick wiener). In order to determine the microbiological safety of final products, the total number of aerobic mesophilic bacteria and the number of Listeria monocytogenes were measured. Consumer assessment and quantitative flavor profiling (QFP) were used for analysis of organoleptic quality. After 7 days of storage, it was found that the effectiveness of the selected additives against the growth of aerobic mesophilic bacteria was unsatisfactory. Only after application of PANA4 did the product not show undesirable changes that would disqualify it from consumption. Each of the functional additives used had a high level of efficacy in inhibiting the growth of Listeria monocytogenes. Meat products with PANA4 addition had the highest consumer acceptance of the overall appearance. The best intensity of flavor bouquet, meat aroma and color, assessed by QFP method, was characterized by the samples with AFX and PANA4 in their recipe

Effects on Quality Properties of Pork Sausages Enriched with Sea Buckthorn (Hippophae rhamnoides L.)

The present study was aimed at evaluating the effect of a sea buckthorn (Hippophae rhamnoides L.) fruit extract on selected quality properties of cooked sausages. The ethanolic extract of sea buckthorn fruit (SBE) incorporated at the highest level (3%) significantly affected the pH, weight losses, and instrumental color parameters of sausages. The SBE deteriorated organoleptic properties of sausages like juiciness, overall appearance, texture, and taste; however the sausages manufactured with 1.5% SBE were scored higher for color and almost the same as control for smell acceptance. Textural parameters like hardness, springiness, gumminess, and chewiness of cooked sausages decreased along with SBE addition. After 28 days of storage, the samples with 1.5% SBE addition were as springy, hard, and gummy as the control ones. Incorporation of SBE increased the shelf life of sausages. The highest inhibition of lipid oxidation was observed in the samples manufactured with 1.5% SBE. The SBE significantly improved the microbial qualities of sausages

Description of the Guelder Rose Fruit in Terms of Chemical Composition, Antioxidant Capacity and Phenolic Compounds

The Viburnum opulus (guelder rose) fruit is a Polish native fruit that grows across almost the entire territory of the country, except for the Tatra Mountains. The fruits are rich in nutrients and biologically active compounds, however, they are rarely used for food production or as a dietary ingredient. This study assessed this fruit for dry matter (17.3% ± 0.7), extract (13% ± 0.53), titratable acidity (1.78 g/100 g ± 0.48), pectin (1.10% ± 0.97), vitamin C (47.79 mg/100 g ± 1.02), the amount of sugar identified as fructose (6.85 g/100 g ± 0.67), antioxidant activity, ABTS (14.64 ± 0.61 μM Trolox/100 g), FRAP (211.14 ± 1.04 µM Trolox/100 g) and total polyphenolic content TPC (1695.88 ± 0.86 mg GAE/100 g). The analysis of phenolic identification was performed using the ACQUITY Ultra Performance LC (UPLC) system with the binary solvent manager and PDA detector

Effect of Ilex x meserveae Aqueous Extract on the Quality of Dry-Aged Beef

The effect of meat marinating with aqueous extract of Ilex meserveae dried leaves on dry-aged beef quality was investigated. Shear force, TBARS value, color parameters, fatty acid profile, and sensory properties were evaluated in beef cuts dry-aged for 21 days. The use of Ilex meserveae dried leaves as marinade at 0.5, 1.0, and 2.0% w/v did not affect the shear force and color parameters of dry-aged beef. The marinating of beef cuts with Ilex meserveae resulted in efficient prevention of lipid oxidation without impairing sensory acceptability. Aqueous extract Ilex meserveae can be applied as a natural ingredient in meat marinade to prevent peroxidation
