Low-fat frankfurters (10% fat, 13% protein) were produced with 3.0% potato starch, finely ground toasted bread and rice bran or their combination. No differences (P > 0.05) were found in processing yield and purge accumulation among treatments of tested ingredients. Potato starch (3.0%) significantly increased the lightness, hardness and skin strength of low-fat frankfurters. Finely ground toasted bread had the highest scores for visual color, external redness, flavor intensity and overall acceptability and improved (P < 0.05) skin strength of frankfurters in comparison to potato starch. Low-fat frankfurters with 3.0% rice bran had the same (P>0.05) visual color scores, redness and textural properties as those produced with potato starch and toasted bread, but lower (P < 0.05) flavor intensity and overall acceptability and were judged as "just acceptable". Decreasing the rice bran from 3.0 to 1.5% and using it in combination with toasted bread (0.75%) and potato starch (0.75%) had an insignificant effect on the flavor intensity and overall acceptability of low-fat frankfurters. 相似文献

Optimization of salt, olive oil and pectin level for low-fat frankfurters produced by replacing pork backfat with olive oil 总被引:1,自引:0,他引:1
Response surface methodology was used to determine the optimum salt level (1.3-2.1%) and pectin level (0.25-1.0%) when olive oil replaced pork backfat (0-100%) for the production of highly acceptable low-fat frankfurters (9% fat, 13% protein). The test ingredients significantly affected (P<0.05) jelly separation of the batter, skin strength, hardness, saltiness, odour and taste and the overall acceptability of the low-fat frankfurters. Batters with high pectin levels recorded the highest (P<0.05) jelly separation. Low-fat frankfurters with high salt levels tended to have very hard skins and increased (P<0.05) saltiness while those with a high pectin level were very soft, tasted like cream and had the lowest (P<0.05) score for odour and taste. The low-fat frankfurters with 1.8-2.1% salt, 0-35% olive oil and 0.25-0.45% pectin had the highest overall acceptability. However, low-fat frankfurters produced with 1.3% salt, 0.25-0.30% pectin and 80-100% olive oil were also acceptable. Such low-fat frankfurters, compared to commercial products, have a 48% lower salt content (from 2.5 to 1.3%) and 66.6% lower fat content (from 30 to 10%), in which 80-100% of the added fat is olive oil. Further research is needed to improve the acceptability of these frankfurters. 相似文献

EFFECT OF CARRAGEENAN ON PROCESSING AND QUALITY CHARACTERISTICS OF LOW-FAT FRANKFURTERS 总被引:1,自引:0,他引:1
Three types of carrageenan (K, I, K+I) × 4 levels (0, 0.25, 0.5 and 1.0%) were evaluated with a complete factorial design to characterize the effect of carrageenans on processing and quality characteristics of low-fat frankfurters (9% fat, 13% protein). l-Carrageenan at 0.5–1.0% level appeared to be more beneficial for the production of low-fat frankfurters. It reduced (P<0.05) the hardness of the skin and contributed to a softer (P<0.05) product and higher overall acceptability. Low-fat frankfurters (9% fat) manufactured with I-carrageenan (IC) or in combination with finely ground toasted bread (TB), isolated soy protein (ISP) and pork skin (PSK), were compared to high-fat (27% fat, 11% protein) and to low-fat (9% fat, 13% protein) control frankfurters prepared with 3.5% potato starch (PS), as well as with commercial frankfurters (25% fat, 11.6% protein, 4.5% starch). Frankfurters with IC had higher (P<0.05) moisture, softer (P<0.05) skin and the highest (P<0.05) separation of gelatin. However, textural properties and overall acceptability were similar (P>0.05) to commercial and high-fat control frankfurters. Addition of TB had no significant effect. Use of ISP and PSK improved (P<0.05) the water-binding capacity but negatively affected the overall acceptability of frankfurters. 相似文献

探讨添加可得然胶(0.3%,肉总质量计)以及不同加水量(20%、23%、26%和29%,肉总质量计)对法兰克福香肠品质特性的影响。测定蒸煮损失率、乳化稳定性、色差、质构、流变特性、微观结构以及感官评价,同时应用低场核磁共振(low field nuclear magnetic resonance,LF-NMR)技术测定法兰克福香肠内部水分子的迁移规律。结果表明,在不添加可得然胶对照组中,随着加水量的增加,法兰克福香肠的蒸煮损失率和L*值显著增加(P<0.05),而乳化稳定性、硬度和总体可接受性显著降低(P<0.05)。然而,在添加可得然胶后,在相同加水量条件下显著降低法兰克福香肠的蒸煮损失率,并显著提高肉制品的乳化稳定性、硬度、弹性和总体可接受性(P<0.05)。LF-NMR研究结果表明,可得然胶的添加能够降低法兰克福香肠的弛豫时间,在较高加水量条件下增强对水分子的束缚能力。另外,肉糜的流变学测定结果表明,在相同加水量条件下,添加可得然胶能够提高肉糜在加热终点的储能模量(G’)和损失模量(G”),而且降低相位角正切值(tanδ),说明可得然胶能够在较高加水量条件下提高肉糜的黏弹性。同时,扫描电镜结果表明,较高的加水量会导致蛋白凝胶结构松散,而可得然胶的添加能够显著改善蛋白凝胶的网状结构。上述结果表明,虽然过多的加水量会导致法兰克福香肠的品质下降,但是可得然胶的添加能够在较高加水量条件下显著提高法兰克福香肠的食用品质,为可得然胶在乳化肉糜类肉制品中的应用提供理论依据。 相似文献

将1 g/100 mL氧化绿原酸添加到以猪血浆蛋白水解物作为乳化剂所制备的水包油型乳状液中,以此获得高稳定性的植物油预乳状液。然后将该预乳状液以15%、30%、45%和60%的比例替代猪脂肪加入到法兰克福香肠中,探讨替代脂肪比例对香肠品质特性的影响。测定香肠的蒸煮损失、质构、色度以及水分迁移规律,同时测定肉糜的乳化稳定性和流变特性。结果表明,随着预乳状液替代比例的增加,香肠的蒸煮损失显著降低(P<0.05),硬度、咀嚼性、L*值和b*值显著增加(P<0.05),而弹性、黏结性、感官评价无显著变化(P>0.05)。低场核磁研究结果发现,预乳状液替代比例的增加能够显著缩短香肠的弛豫时间(P<0.05),说明其能增强蛋白质网络对水分子的束缚能力。与此同时,随着预乳状液替代比例的增加,肉糜的乳化稳定性显著增加(P<0.05)。另外,肉糜的流变学测定结果表明,随着预乳状液替代比例的增加能够显著提高肉糜在加热终点的储能模量(G’)和损失模量(G′′),而且显著降低了相位角正切值(tanδ)(P<0.05)。在法兰克福香肠的制作中猪脂肪能够被预乳状液部分替代,而且对香肠的感官无显著影响,尤其以45%的替代量为最佳。 相似文献

In this study, grape seed flour (GSF) obtained from wine by-products was incorporated into frankfurters at seven concentrations (0, 0.5, 1, 2, 3, 4, and 5%) and the effects occurred on physical, nutritional and sensory characteristics of the products were investigated. The colour values (L*, a* and b*) of frankfurters generally decreased (p < 0.05) on account of the increasing amount of GSF. The utilization of this flour also led to a decline in the oxidation level of the products (p < 0.05), probably due to its antioxidant content. The increment of GSF in the frankfurters enhanced the protein, total dietary fibre and water holding capacity of the treatments (p < 0.05). Although the level of GSF above 0.5% reduced overall acceptability, the frankfurters containing the level up to 2% received scores above the average. The evaluation of wine by-products in the production of healthier and functional frankfurters has been achieved by the study, but further research is necessary to improve palatability of the products. 相似文献

Eighteen gilts (75 kg) were injected daily with 0, 2.5, or 5 mg of porcine somatotropin (pST) for either 30 or 31 days prior to slaughter to examine the effects of dose of pST administration to swine on processing characteristics of frankfurters manufactured from pork. Frankfurters were manufactured from New York shoulders (NAMP #404) and formulated with fat from the same carcass to a final product target of 22% fat and 10% added water. Frankfurters from pST- treated gilts had lower smokehouse yields (0.9% decrease; P <.005) and greater shear force peak height (35.4% increase; P < 0.05) compared with the controls. The increased shear force required for skin failure of frankfurters manufactured from pork from pST-treated pigs was not readily explained by other differences due to treatment (e.g., cooking stability, batter proximate composition or salt soluble protein content; all P > 0.05) 相似文献

The antilisterial activity of sodium lactate (SL) and sodium diacetate (SD) was evaluated in a frankfurter formulation and in combination with a dipping treatment into solutions of lactic acid or acetic acid after processing and inoculation. Pork frankfurters were formulated with 1.8% SL or 0.25% SD or combinations of 1.8% SL with 0.25 or 0.125% SD. After processing, frankfurters were inoculated (2 to 3 log CFU/cm2) with a 10-strain composite of Listeria monocytogenes and left undipped or were dipped (2 min) in 2.5% solutions of lactic acid or acetic acid (23 +/- 2 degrees C) before vacuum packaging and storage at 10 degrees C for 40 days. Total microbial populations and L. monocytogenes, lactic acid bacteria, and yeasts and molds were enumerated during storage. Sensory evaluations also were carried out on frankfurters treated and/or formulated with effective antimicrobials. The combination of 1.8% SL with 0.25% SD provided complete inhibition of L. monocytogenes growth throughout storage. Dipping in lactic acid or acetic acid reduced initial populations by 0.7 to 2.1 log CFU/cm2, but during storage (12 to 20 days), populations on dipped samples without antimicrobials in the formulation reached 5.5 to 7.9 log CFU/cm2. For samples containing single antimicrobials and dipped in lactic acid or acetic acid, L. monocytogenes growth was completely inhibited or reduced over 12 and 28 days, respectively, whereas final populations were lower (P < 0.05) than those in undipped samples of the same formulations. Bactericidal effects during storage (reductions of 0.6 to 1.0 log CFU/ cm2 over 28 to 40 days) were observed in frankfurters containing combinations of SL and SD that were dipped in organic acid solutions. Inclusion of antimicrobials in the formulation and/or dipping the product into organic acid solutions did not affect (P > 0.05) the flavor and overall acceptability of products compared with controls. The results of this study may be valuable to meat processors as they seek approaches for meeting new regulatory requirements in the United States. 相似文献

Regular frankfurters treated with tofu powder had decreased fat with no significant differences in color, texture, or overall acceptability compared to a control by sensory analysis. Lean frankfurters with tofu powder had lower moisture and color, better texture, and overall acceptability with no flavor differences from controls. Except for fracturability, there were no differences in texture-related parameters by Texture Profile Analysis (TPA) between regular and control frankfurters but treated lean frankfurters had improved texture. Lean pork sausages treated with tofu powder were lower in fat, higher in protein, and moisture with no differences in sensory attributes compared to controls. 相似文献

This study evaluates the physicochemical and sensory properties of healthier frankfurters with 25% added walnut (WF) versus low-fat frankfurters (6% pork fat) (LF) and traditional frankfurters (18% pork fat) (NF). Results reveal that cooking losses were unaffected (p ? 0.05) by the formulation of frankfurters. The addition of walnut led to higher (p < 0.05) redness and yellowness values, while colour parameters did not differ significantly between LF and NF sausages. Frankfurters with added walnut (WF) presented higher (p < 0.05) hardness and chewiness values than LF and NF frankfurters. Differences in composition were also accompanied by changes in the microstructure of the gel/emulsions. Frankfurters with added walnut presented a flavour significantly different from meat and scored lower (p < 0.05) on texture preferences. However, all frankfurters scored the same for overall acceptability. 相似文献

Effects of fat level and maltodextrin on the functional properties of frankfurters formulated with 5, 12 and 30% fat 总被引:4,自引:0,他引:4
The effects of fat level (5, 12 and 30%) and maltodextrin on emulsion stability, cook loss, colour, texture and sensory characteristics of frankfurters were investigated. Three fat levels (5, 12 and 30%) were formulated containing added maltodextrin. For each fat level a control was prepared without added maltodextrin giving a total of 6 treatments (3×2 factorial design). Reducing the fat from 30 to 5% increased cook loss and decreased emulsion stability. Panellists detected an increase in juiciness and a decrease in overall texture, overall acceptability when the fat level was reduced from 30 to 5%. Instron texture profile analysis showed a decrease in hardness, chewiness and gumminess and an increase in springiness with decreasing fat level. Maltodextrin addition caused a significant decrease in cook loss of the frankfurters but also decreased the emulsion stability. An interactive effect (P<0.05) occurred between fat level and maltodextrin resulting in no significant difference in hardness, gumminess and chewiness values when maltodextrin was present in the reduced-fat (5 and 12%) frankfurters. Saltiness, overall flavour intensity, overall texture and overall acceptability were unaltered (P>0.05) by maltodextrin. The results indicate that maltodextrin can be used as a suitable fat replacer since it offset some of the changes brought about by fat reduction, decreasing cook loss and maintaining a number of textural and sensory characteristics of the frankfurters. 相似文献

Sodium lactate and protective culture effects on quality characteristics and shelf-life of low-fat frankfurters produced with olive oil 总被引:2,自引:0,他引:2
Low-fat frankfurters (9% fat, 13% protein) were produced with olive oil and four levels of sodium lactate (0, 1, 2, 3%). The level of sodium lactate affected (p < 0.05) moisture and ash content, processing yield, skin strength and saltiness of low-fat frankfurters. Sodium lactate at 2% level appeared to be more beneficial for the production of low-fat frankfurters with olive oil. It had the highest score for flavour intensity and did not negatively affect skin strength, lextural and sensory properties or the colour of frankfurters. Low-fat frankfurters (9% fat, 13% protein) with olive oil, produced with 0% and 2% sodium lactate (SL) and protective culture (PC) and stored under vacuum at 4 °C, were compared with high-fat frankfurters (27% all animal fat, 11% protein). Low-fat frankfurters with olive oil had higher (p < 0.05) moisture and lower (p < 0.05) brine concentration than high-fat frankfurters. PC extended shelf-life of low-fat frankfurters with olive oil from 3 to 4 weeks. 2% SL kept the pH of frankfurters almost constant and extended shelf-life up to 6 weeks compared with 3 and 4 weeks shelf-life for low-fat and high-fat control frankfurters, respectively. 相似文献

The three-components mixture design was applied to optimise a ratio of NaCl (0%–65%), KCl (35%–100%) and glycine (0%–20%) in reduced-sodium frankfurters. Fourteen frankfurters were analysed for texture and colour, and consumer (n = 100) acceptability. Results indicated that NaCl levels affected consumer acceptability of reduced-sodium frankfurters. Increasing NaCl generally increased texture hardness. Optimisation of a salt mixture was performed by superimposing contour plots of predicted acceptability scores (≥5.5 on a 9-points hedonic scale) of all sensory attributes and revealed the optimal salt mixture: 40.03%–63.66% NaCl, 35.00%–55.90% KCl and 0.00%–20.00% glycine. The optimal salt mixture contained 220–340 mg Na/100g frankfurter compared with 540 mg Na/100 g of the control formulation (100% NaCl). The mean overall liking score (5.9 vs. 5.9) of the optimal reduced-sodium frankfurter was not different from the control (100% NaCl). This optimal formulation had >25% sodium reduction and could be claimed as ‘reduced-sodium’ according to US Food and Drugs Administration regulation. 相似文献

Cottonseed Proteins in Frankfurters: Effect on pH, Cured Color, and Sensory and Physical Properties 总被引:1,自引:0,他引:1
Frankfurter-type sausages were made in which 5%, 10%, or 15% of the meat was replaced with the following cottonseed-derived protein products: genetically glandless cottonseed flour (CF); liquid cyclone processed deglanded cottonseed flour (LCPC); genetically glandless cottonseed storage protein isolate (CI). All-meat controls (0% cottonseed protein additive) were formulated at each replacement level with fat contents equivalent to those of the cottonseed protein-added frankfurters. Compared to all-meat controls, frankfurters made with increasing levels of cottonseed proteins generally had higher pH values, less cured color, less firmness of skin, softer texture, and were less desirable as judged by sensory panels. At the 10% and 15% replacement levels, frankfurters containing LCPC, had significantly (P < 0.05) lower scores for external and internal visual color, overall satisfaction and bioyield and rupture force values than did Cl-added frankfurters. Simple correlation coefficients suggest that significantly (P < 0.05) correlated responses exist within and across replacement levels between pH and sensory panel scores, Instron values and visual color scores. 相似文献

Oil (healthier lipid combination of olive, linseed and fish oils)-in-water emulsions stabilized with different protein systems (prepared with sodium caseinate (SC), soy protein isolate (SPI), and microbial transglutaminase (MTG)) were used as pork backfat replacers in low-fat frankfurters. Microstructure, lipid oxidation, nitrite content, microbiological changes and biogenic amine formation of frankfurters were analyzed and found to be affected by the type of oil-in-water emulsion and by chilling storage (2° C, 41 days). Although the lipid oxidation levels attained were low, replacement of animal fat by healthier oil combinations in frankfurter formulation did promote a slight increase in lipid oxidation. Residual nitrite was affected (P < 0.05) by formulation and storage. Only 51-61% of the added nitrite was detectable in the product after processing and 17-46% at the end of storage. The microbial population was low in all formulations during chilling storage. Spermine was the most abundant amine (19-20 mg/kg), but similar in level to all samples. 相似文献

The colour attributes in a control and six more treatments of frankfurters (18% fat) produced with natural colourants and two levels of NaNO(2) (0 and 150 mg/kg) were studied. The following natural colourants, permitted by the EU 94/36 guideline, were used: E 100 curcumin (CU), E 120 carminic acid (CA), E 150a caramel (CR), E 160a beta-carotene (BC), E 160g paprika-extract (PE) and E162 betanin (B). CA, B, BC and PE significantly increased the redness of batter, while BC, PE and CU increased (p<0.05) the yellowness. NaNO(2) decreased (p<0.05) the redness of batters in all treatments. Frankfurters with CA had the highest a* value followed by those with BC, PE and B. BC, PE and B increased the yellowness of frankfurters. NaNO(2) increased (p<0.05) the redness of frankfurters in all treatments. The storage of frankfurters for 4 weeks had no effect on redness and yellowness of frankfurters. Exposure either for 2 h in sunlight or for 4 h in artificial light had no significant effect on redness and yellowness of frankfurters from all treatments. Canned frankfurters (117°) with B had the greatest decrease in redness while those with BC the greatest increase in yellowness. Frankfurters with B were the most acceptable from the consumers according to their colour followed by those with PE. Frankfurters with B had also the highest score for overall acceptability, followed by those with CA and nitrites. By employing discriminant analysis on the data, equations were derived for the identification of the natural colourant used in the production of frankfurters. Results from frankfurters, produced with 0, 3.6, 14.4 and 28.8 mg of pure B kg and 100 and 150 mg/kg NaNO(2), have shown that the level of NaNO(2) can be reduced from 150 to 100 mg/kg with appropriate increase in B level and frankfurters with 14.4 mg B/kg were the most acceptable from the consumers according to their colour. 相似文献

Effects of oat fibre and carrageenan on the texture of frankfurters formulated with low and high fat
The effects of fat level (5, 12 and 30%), carrageenan and oat fibre on the texture of frankfurters were evaluated using mechanical
properties and sensory (taste panel) methods. Textural profile analysis (TPA) indicated that fat reduction decreased hardness,
adhesiveness, gumminess and chewiness. In contrast, springiness increased when the fat content was reduced from 30% to 5%.
No relationships between fat content and either Warner-Bratzler or Kramer shear parameters were found. Carrageenan and oat
fibre differed in their effects on TPA values but the latter was more effective at improving texture. Taste panellists did
not detect any differences in hardness, springiness or gumminess when fat was reduced from 30% to 5%, although increases in
cohesiveness, chewiness, moisture release and lumpiness were observed. Overall acceptability of the texture decreased as the
fat level was reduced. Carrageenan and oat fibre improved the acceptability of the 12% fat frankfurters, but neither ingredient
offset the detrimental effects on acceptability of the texture when fat was reduced to 5%. The results demonstrate that carrageenan
and oat fibre can partially offset some of the textural changes (juiciness, cohesiveness, lumpiness) which occur in low-fat
frankfurters when added water replaces fat and the protein level remains constant.

This study was designed to explore the potential of refined, bleached and deodorized (RBD) palm oil (PO) and palm stearin (POs) utilization in chicken frankfurters. A 10 points augmented simplex-centroid design was used to study the effect of chicken fat (CF), PO and POs as well as the interaction of these fats on the emulsion, textural and sensory properties of chicken frankfurters. All frankfurters were formulated to contain approx 25% fat, 52% moisture and 10% protein. No significant difference was found in end chopping temperatures of all meat batters even though the temperature of PO and POs upon incorporation into meat batters was 50°C higher than CF. Strong emulsions were formed as no fluid losses were observed in all the meat batters tested after heating. Texture profiles of the frankfurters containing PO and/or CF were quite similar, but increment of POs raised hardness, chewiness, and shear hardness of the frankfurters. Acceptability of the frankfurters was evaluated using hedonic test. Panelists found no difference in hardness preference between frankfurters made from totally CF and PO, while frankfurters made from POs were rated as hard and brittle. CF was important in determining acceptability of the frankfurters, as reduction of CF in formulation resulted in lower scores in chicken flavor, juiciness, oiliness and overall acceptance of the frankfurters. Frankfurters with sensory acceptability comparable to a commercial one were found to comprise of more than 17% CF, and less than 67% PO and 17% POs of the fat blend. 相似文献

The effect of processing conditions such as frying time and temperature, and batter formulation on pore development in deep‐fat fried chicken nuggets coatings were studied using helium pycnometer method. Chicken nuggets with preformed and laboratory prepared batter coatings were fried at temperatures between 170 and 190 °C for a time range between 0 and 240 s. There was significant (P < 0.05) effect of frying temperature and batter formulation on porosity. Porosity increased with frying time and temperature, and ranged between 2.15 and 47.92% for the preformed batter and 9.96 and 54.76% for the formulated batters. Apparent and bulk densities of the preformed batters increased and decreased with frying time, respectively, but both declined gradually with increasing frying temperature. As the level of rice flour in the formulation increased, apparent and bulk densities also increased. Batter formulation and frying temperature significantly (P < 0.05) influenced the variation in moisture and fat content of the fried batter. Porosity demonstrated positive and negative correlation with fat uptake and moisture loss, respectively, for all the batter coatings. 相似文献

Effect of kimchi powder level and drying methods on quality characteristics of breakfast sausage 总被引:1,自引:0,他引:1
This study was conducted to determine the effect of the addition of kimchi powder on the quality characteristics of meat batter and breakfast sausage. Breakfast sausages were supplemented with freeze dried kimchi powder (FKP) or hot air dried kimchi powder (HKP) at levels of 1% (FKP-1 and HKP-1) or 2% (FKP-2 and HKP-2). The emulsion stability, cooking yield, and apparent viscosity in meat batters improved with increments of kimchi powder (p < 0.05). Increased levels of kimchi powder in breakfast sausage decreased the L∗ value, pH, and springiness, and increased the a∗ value, b∗ value, hardness, chewiness, and gumminess (p < 0.05). Sensory evaluations indicated that a higher overall acceptability was attained when the kimchi powder was added to breakfast sausage at a level of 2%. 相似文献
