  • The quality characteristics of pork patty prepared with chitosan containing preservatives during storage at $4^{\circ}C$ were investigated to improve its functional property and shelf life using food preservatives of natural origin (PI; 0.1% chitosan, 2.5% citric acid, 100 ppm grapefruit seed extract, 0.2% adipic acid, 0.1% Cinnamomum extract, D.W. 97.09% and PII; 0.1% chitosan, 2.5% citric acid, 100 ppm grapefruit seed extract, 0.2% adipic acid, 0.1% Lysimachia christinae Hance extract, D.W. 97.09%). The sensory qualities (taste, appearance, texture and overall acceptability) of patties preserved with PI (1, 3 and 5%) and PII (1, 3 and 5%) were also investigated. The taste and overall acceptability of patties prepared with 1% PI and 1% PII were higher than those of the control. The DPPH radical scavenging activities of the control, 1% PI and 1% PII treated patties were 13.54%, 21.78% and 14.07%, respectively. The total aerobes and coliform count of patties preserved with 1% PI were $10^4$ CFU/g and $10^2$ CFU/g, respectively, after 10 days storage at $4^{\circ}C$. Cooking loss from 1% PI and 1% PII treated patties was lower than that of from the control. Water holding capacity was the highest for 1% PI (65.84%), followed by 1% PII and then the control. The shelf life of patties prepared with 1% PI and 1% PII was extended by about 5 days relative to the control at $4^{\circ}C$.

  • This study was carried out to investigate the effect of lotus root and leaf powder on the quality characteristics of pork patty stored at $3^{\circ}C$ for 9 days. The pork patties were of four types: nothing added(control, T0), 0.5% lotus root powder added (T1), 0.25% lotus root and 0.25% lotus leaf powder added (T2), and 0.5% lotus leaf powder added (T3). The $a^*$ value tended to decrease with longer storage period (p<0.05). The $L^*$ and $a^*$ value of T3 had the lowest value among the samples, the $b^*$ value T2 and T3 were higher than those of T0 and T1 (p<0.05). Water holding capacity decreased with longer storage period (p<0.05), the water holding capacity, cooking loss, increase rate of thickness and decrease rate of diameter were not significantly different among the samples. Hardness and chewiness increased and springiness decreased with longer storage period (p<0.05). The pH creased with longer storage period (p<0.05), but the VBN content not changed during storage. The TBARS values increased with longer storage period (p<0.05), and those of T0, T1, T2 and T3 were 4.57, 1.85, 0.43 and 0.41 mg MA/kg, respectively, after 9 days of the storage. The result suggest that the addition of lotus root and leaf powder at the same time, or addition of lotus leaf powder can be applied to pork patty to its functionality.

  • Purpose: The objective of this study was to examine the effects of pork liver levels on the quality characteristics of hamburger patties. Methods: The effects of the addition of livers concentrations from 0% to 20% were investigated based on chemical composition, cooking characteristics, physicochemical properties, shear force, and sensory characteristics of hamburger patties. Results: The increasing pork liver levels from 0% to 20% resulted in increased moisture content, ash content, redness, reduction in diameter, and reduction in thickness of hamburger patties, but decreased the fat content, lightness, cooking yield, shear force and water holding capacity of hamburger patties. The protein content of hamburger patties with different amounts of pork liver showed no significant differences. The hamburger patties with increasing pork liver levels had lower color, flavor, juiciness, and overall acceptability scores, but the overall acceptability of control showed similar trends to T1 (treatments with 5% pork liver). Conclusion: Pork liver in the formulation showed similar quality characteristics as compared to control hamburger patties without liver, with best results obtained on adding up to 5% pork liver.

  • This study investigated the effect of the powder produced by ball-milling the outer layer of annatto (Bixa orellana L.) seeds on the physicochemical properties as well as the antioxidant and antimicrobial activities of pork patties over 14 d of refrigerated storage (4±1℃). Five pork patty treatments were produced containing three different concentrations of annatto seeds, 0.1, 0.25 and 0.5% (ANT0.1, ANT0.25, ANT0.5), 0.1% ascorbic acid (AA0.1), and a control (CTL). Based on the results, annatto seed powder appeared to show antioxidant activity. The Hunter color values of pork patties were affected by the addition of annatto seed powder, which increased the redness and yellowness values, but decreased the lightness of the patties (p<0.05). To evaluate the antioxidative effects of annatto on pork patties, thiobarbituric acid reactive substances (TBARS) and peroxide values (POV) were analyzed over 14 d of refrigerated storage. Treatments containing annatto seed showed lower TBARS and POV than control (CTL) samples (p<0.05). The volatile basic nitrogen (VBN) of the pork patties containing annatto seeds were lower than that of CTL at the end of storage (p<0.05). Although no differences in total bacterial counts were observed between control and treated patties, those containing annatto seeds had lower microbial counts for Enterobacteriacease than CTL or AA 0.1%. Therefore, annatto seed powder might be a good source of natural antioxidants for the production of meat products.

  • This study was performed to evaluate the antioxidant activity of oven-dried tomato powder (OTP) as affected by drying temperature and the effect of OTP on the product quality of pork patties. Three OTP products were obtained by drying of fresh tomato at 60, 80 and 100℃ oven until constant weight was obtained. Total phenolic content of three kinds of OTPs ranged from 1.95 to 5.94 g/100 g. The highest amount of total phenolic compound was observed in OTP dried at 100℃. Antioxidant activity of three kinds of OTPs was measured by 1,1-diphenyl-2-pycrylhydrazyl (DPPH)-radical scavenging activity, iron chelating ability, reducing power and measurement of lipid peroxide in linoleic acid emulsion system. In all parameters, OTP at 100℃ showed the higher antioxidant activity than other temperatures (p<0.05). Based on the model study, the physicochemical properties, and antioxidant and antimicrobial activities of pork patties containing 1% OTP were measured. Redness of pork patties were increased with the addition of OTPs (p<0.05). Thiobarbituric acid reactive substances (TBARS) values of raw pork patties containing OTPs were lower than those of control (CTL) until 7 d of storage, regardless of drying temperatures (p<0.05). Peroxide values of pork patties made with OTP (1%) were lower than those of CTL until the end of storage time (p<0.05). However, no antimicrobial activities were observed among the treatments (p>0.05). Therefore, OTPs could be used as a natural antioxidant in meat products.

  • This study was performed to assess the antioxidant activity of Allium hookeri root extract (AHE) on lipid oxidation of raw sulfur-fed pork patties for 14 d of refrigerated storage. Different concentration of ethanol (0-100%) and time (1-12 h) were applied to determine the extraction condition. Water (0% ethanol) extraction for 1 h was selected as an optimal extraction condition of AHE for the following study showing the highest total phenolic content and total flavonoid content, as well as the strongest antioxidant activity. The 1% AHE (SP1), 3% AHE (SP2), and 0.05% ascorbic acid (SP3) were added into sulfur-fed pork patties against controls; SP0 (sulfur-fed pork patties with no AHE) and P0 (normal pork patties with no AHE). The pH values of P0 and SP0 significantly increased (p<0.05) than others on 14 d and redness of P0 showed the largest decrement during storage. P0 and SP0 showed higher production of conjugated dienes on d 7 than others (p<0.05). Thiobarbituric acid reactive substances (TBARS) values were decreased in proportion to the increased level of AHE on 14 d (p<0.05) resulting in higher TBARS values on P0 and SP0 (p<0.05) and the negative correlation between AHE level and TBARS were also demonstrated (r=-0.910, p=0.001). Therefore, the results suggest that AHE effectively retarded the lipid oxidation rate of sulfur-fed pork patties indicating the potential usage of AHE as a natural preservative.

  • Sea tangle (Laminaria japonica) is well known as having anti-diabetic and hypolipidemic effects in animals as well as in humans. In this study, we evaluated the effects of sea tangle-added patty on postprandial blood glucose and lipid profiles in borderline-hypercholesterolemic (cholesterol ${\geq}200$ mg/dL) adults. Eleven subjects voluntarily participated in the experiment, and each subject provided written consent. Experimental patty (E) was made by adding 2.25 g of sea tangle powder as a substitution to 1.125 g each of pork and chicken. In the first week, 200 g of Control patty (C) was provided to each subject, who had fasted more than 12 hours. In the second week, the same amount of E patty was supplied under the same conditions. Serum glucose levels increased significantly less at 30, 60, and 120 min after consumption of E patty compared to the levels at all time points after eating C patty. Thus, the change in the area under curve (${\Delta}AUC$) of serum glucose levels through 120 minutes was lower when consuming E patty compared to C patty. Although serum C-peptide concentrations were not significantly different at all time points between the two patties, the ${\Delta}AUC$ of serum C-peptide concentrations through 120 minutes was lower when consuming E patty compared to C patty. However, there were no differences in serum levels of triglyceride, total cholesterol, LDL-C, and HDL-C at 30, 60, 120, 180, and 240 min between the two patties. Further, each ${\Delta}AUC$ of these lipid levels through 240 minutes was not significantly different between the two patties. The results indicate that sea tangle-added patty may decrease postprandial plasma glucose concentrations and reduce insulin secretion, although it might not ameliorate serum lipid profiles in adults with borderline-hypercholesterolemia.

  • The brown soybean extract (BE, extracted by distilled water, 50%, 75%, and 95% ethanol) were analyzed for their total phenol, flavonoid, anthocyanin content, and DPPH radical-scavenging activity to determine antioxidant activities. Brown soybean extract with 75% ethanol showed significantly higher DPPH radical scavenging activity, total phenol and anthocyanin content compared to the other treatments (p<0.05). Then, brown soybean extract with 75% ethanol was applied to pork patties at different concentration (0.05%, 0.1%, and 0.2%) and lipid oxidation was evaluated during 15 d of refrigerated storage. Addition of BE significantly increased redness and pH values, respectively (p<0.05). Moreover, TBARS value of pork patties decreased significantly (p<0.05) as BE concentration increased. In sensory evaluation, pork patties with 0.1% BE had significantly higher score than other treatments in flavor and overall acceptability (p<0.05). Consequently, these results indicate that 0.1% BE could be an effective natural antioxidant to inhibit lipid oxidation in pork patties.

  • Pork patties were formulated with either steam-dried green tea power or freeze-dried raw tea leaf powder, and the quality characteristics of these products were monitored. Proximate analysis of tea powder contained 17.80~19.85%, 4.70~5.73%, and 5.60~5.77% (as is) crude protein, crude fat, and crude ash, respectively. There were no significance differences in pH among the samples. Chromaticity tended to decrease brightness ($L^*$) and redness ($a^*$), and there were significant differences in yellowness ($b^*$) as the added amount of tea power was increased. For texture, hardness increased as more green tea powder was added. Thiobarbituric acid reactive substances (TBARS) and volatile basic nitrogen (VBN) values increased after storage for 12 days, whereas samples formulated with green tea powder showed lower TBARS and VBN values compared to control groups. Sensory panelists showed preference for samples with green tea powder added compared to the control group.

  • The effects of reducing pork hind legs concentrations from 80% to 60% and replacing the pork head meat with up to 20% pork head meat were investigated based on chemical composition, cooking characteristics, physicochemical properties, shear force, and sensory characteristics of hamburger patties. The increasing the pork head levels from 0% to 20% increased the protein content, pH, reduction in diameter, reduction in thickness, and shear force of hamburger patties, but decreased the moisture content, lightness, redness, yellowness, cooking yield, and water holding capacity of hamburger patties. The fat and ash contents of the hamburger patties with different amounts of pork hind legs and pork head showed no significantly different sensory characteristics from the control and all the treatments (p>0.05). The hamburger patties with increasing pork head levels had lower color, flavor, juiciness, and overall acceptability scores, but the overall acceptability of control showed similar trends to T1 and T2. Therefore, replacing pork hind legs with pork head meat in the formulation was successfully similar to control hamburger patties, with best results obtainedon replacing up to 10% pork head meat.
