Low-fat sausages were prepared with fresh chicken breast meat and formulated with different levels of added fat, whey protein concentrate, and hydrocolloids (xanthan and guar gums) to study the effect of composition on the stress relaxation behavior of the products. Stress relaxation experiments were conducted on precooked sausages at 25°C. Generalized Maxwell and empirical Peleg models were used to predict the stress relaxation behavior of the material. A model with seven maxwellian elements in parallel with a pure elastic element showed a very good agreement with experimental data. Results show that the proposed model satisfactorily fits the experimental data better than Peleg's model or Maxwell models with less elements. The relaxation time distribution functions were obtained. The characteristic relaxation time was shorter (2500s) for the formulations with no added fat which produced a less elastic product while the sausages with added fat showed longer characteristic relaxation time (5000s). The stress relaxation experiment differentiated the viscoelastic nature of different formulations due to reduction of fat content. 相似文献

Consumer demands for poultry processed meats have increased due to low fat content. In this experiment, chicken sausages were manufactured with various biopolymers prepared from soybean protein, casein, whey protein isolate (WPI), mixtures of soybean protein and casein, and soybean protein and WPI. The extent of various biopolymer formations was determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and high performance liquid chromatography. Cross-linking soybean protein and casein or WPI by transglutaminase provided biopolymers with improved heat stability and emulsifying property. Shear force of chicken sausages were measured to evaluate the addition of biopolymer on the hardness in the presence of 0.05 or 0.2% sodium tripolyphosphate (STPP). The texture of chicken sausages was improved by the addition of such biopolymers even in the presence of 0.05% STPP. These results suggested that chicken sausage texture was improved by the formation of network structures that contribute to hardness of sausage gels with the addition of biopolymers. Thus, addition of biopolymers in the manufacture of chicken sausages may permit reduction in phosphate content without loss in texture. 相似文献

The relationship between the composition and texture of conventional and low-fat frankfurters 总被引:4,自引:0,他引:4
Marta Ordóñez Jordi Rovira & Isabel Jaime 《International Journal of Food Science & Technology》2001,36(7):749-758
The chemical composition, instrumental texture and sensory properties of eighteen conventional and three low-fat commercially produced frankfurters were analysed. The most important factors in defining the texture of the product were hardness and juiciness, these being related respectively to the percentage of protein and the fat/protein ratio in the frankfurter. Subsequently, using a basic formulation of soya protein and starch, different levels of fat (10 and 15%) and hydrocolloids [carrageenan, carboxymethylcellulose (CMC) and apple pectin] were tested. According to results from these trials, three low-fat formulations were chosen. The three low-fat sausages were a sausage with 15% fat and carrageenan (0.5%), a sausage with 10% fat and a combination of carrageenan (0.5%) and pectin (0.4%) and a sausage with 10% fat and a combination of carrageenan (0.5%) and CMC (0.1%). The sensory and instrumental texture attributes of the three low-fat and the standard sausages were investigated. Results indicated that low-fat (10%) frankfurters with a texture profile similar to standard frankfurters could be manufactured through the addition of mixtures of proteins and hydrocolloids. The combination of carrageenan with CMC or apple pectin is more efficient than the use of carrageenan alone as both combinations allow a higher reduction of fat, at the same time achieving a final texture well liked by consumers. 相似文献

Improvement of nutritional properties of Chorizo de Pamplona by replacement of pork backfat with soy oil 总被引:1,自引:0,他引:1
Dry fermented sausages with a partial substitution of 15, 20 and 25% of pork backfat by pre-emulsified soy oil were prepared. No differences were detected in the water, protein and fat content between control and modified sausages. Cholesterol amount scarcely decreased in the modified sausages (92.96 mg/100 g product in control sausages, 87.71 mg/100 g in sausages prepared with 25% of substitution). No increase in oxidation was detected through chemical or sensory analysis in modified sausages. Saturated fatty acids (SFA) and monounsaturated fatty acids (MUFA) in control products were 37.83 and 45.78 g/100 g of total fatty acid, respectively, decreasing in the modified formulations, to 32.81 and 42.09 g/100 g of total fatty acid in the 25% replacement products, respectively. Polyunsaturated fatty acids (PUFA) increased from 15.22 (control) to 23.96 g/100 g of total fatty acid (25% product) due to the significant increase in linoleic and -linolenic acids when soy oil was added. In relation to texture profile analysis (TPA), hardness and springiness did not show significant differences among products. The instrumental measured colours were comparable with that of commercial products. Sensory evaluation of most of the modified sausages did not show significant differences with regard to the control. 相似文献

Some quality characteristics of frankfurters manufactured in three different fat levels (20%, 10% and 5%) and added citrus fibre (CF) and soy protein concentrate (SPC) were investigated. While moisture content of frankfurters increased with decreasing fat levels, protein contents increased. Lower fat levels resulted in lower water‐holding capacity (WHC), cooking losses and penetrometer values. Lower L* values and higher a* values were obtained in low fat frankfurters. SPC significantly increased the cooking losses in the sausages with 5% and 20% fat, but decreased in the sausages with 10% fat. The lower cooking loss values were obtained in sausages added CF for all fat levels. Addition of fat replacers decreased the L values but did not affect the a and b values. Addition of fat replacers increased hardness in case of low fat levels. The softer product was obtained with high‐fat formulation than low‐fat formulation. Lower taste scores were observed with addition of fat replacers. 相似文献

The recent trend in reducing the fat content in fried foods is leading to the development of low-fat products using batter and breading formulations from protein and other hydrocolloids. The functionality of many of these edible ingredients on moisture retention and fat barrier properties during deep-fat frying is not clearly understood. The objective of this study is to evaluate the effectiveness of hydroxypropyl methylcellulose edible film coating on chicken balls for moisture retention and fat reduction during deep-fat frying. Two sizes (35 and 47 mm) of uncoated and coated chicken balls were fried in peanut oil at 175C for five different frying periods ranging from 30 to 180s for small and 30 to 300s for large balls. The moisture and fat content from the surface layer and core were determined. In comparison to the control, moisture retention up to 16.4% and fat reduction up to 33.7% were observed. 相似文献

Inulin and oligofructose were used as fat replacers in Anzac cookies, blueberry muffins, carrot cake, chocolate cake, lemon cheesecake, ice cream, and beef sausages at levels ranging from 4 to 13g/100g, achieving a significant reduction in fat content (20% to 80% relative). These foods were rated as acceptable by an untrained taste panel, but scored consistently lower than their full‐fat counterparts (controls). Regression analysis showed that, unlike the controls, texture was more important than flavor in determining overall acceptability of the low‐fat foods. Inulin and oligofructose are readily incorporated into bakery and meat formulations, but their use might be limited by adverse physiological effects when consumed at high levels. 相似文献

The effect of varying fat content (8, 12, 16, 20, 24 and 28%) on sausage perceived saltiness was studied using two different formulations, each with 1.2 and 2.0% NaCl. The formulations were made either by varying the proportions of lean pork and pork fat (Series 1) or by replacing water with pork fat on an equal weight basis (Series 2). The replacement of lean pork with pork fat increased the perceived saltiness of the sausages. When water was replaced with pork fat on an equal weight basis the perceived saltiness of the sausage, however, did not change. There was a strong negative correlation (P<0.01) between perceived saltiness and protein content thus suggesting a causative link between these factors. The flavor-enhancing properties of monosodium glutamate (MSG) and Ribotide (monosodium glutamate and 5'-ribonucleotides IMP and GMP) were also studied. MSG only slightly improved the sensory properties of the cooked sausages. 相似文献

Physicochemical and textural properties, and volatile compounds of comminuted sausages with various added fat levels and fat replacers were evaluated. Sausages without added fat had higher expressible moisture and texture values, but their lightness and yellowness values were lower, as compared with sausages with 5%, 10%, or 15% fat. Increased fat levels with constant amounts of lean meat and added water increased the lightness and yellowness values, but tended the redness values tended to be similar. Low‐fat sausages (LFSs, <3%) containing non‐meat proteins, except egg white protein, had reduced texture values similar to those of regular‐fat counterparts (RFC). The addition of non‐meat proteins, except egg white protein, as components of fat replacers in LFS improved the textural characteristics, making them similar to those of RFC. LFSs containing sodium caseinate had reduced concentrations of pentadecanal and octadecanal, resulting in similar volatile compositions to those of RFC. Thus, sodium caseinate was the best non‐meat protein for the improvement of both texture and flavour of LFSs. 相似文献

Fatty acid composition and quality characteristics of low-fat cooked sausages made with beef and chicken meat, tomato juice and sunflower oil 总被引:1,自引:0,他引:1
Low-fat (5.9-10.3% fat) cooked sausages were produced with seven different formulations. Sausages produced with total replacement of fat with sunflower oil had significantly lower oleic acid (C18:1) and higher linoleic (C18:2) and behenic (C22:0) fatty acid contents. Their ratio of TUFA/TS was 3.65 compared to 0.95-1.14 for the other sausages. Also these sausages had the lowest moisture content, highest overall palatability and were less firm. Sausages with tomato juice had the lowest pH value, total aerobic count and nitrite content, but were firmer. Sausages produced with reduced beef contents had lower fat contents, lower stearic (C18:0) and higher oleic (C18:1) fatty acid contents than sausages of high beef content, their texture was very soft and had the lowest score for juiciness. Finally the sausages with chicken meat had the lowest fat and highest salt contents, and lower stearic (C18:0) and higher linoleic (C18:3) fatty acid contents than those made with beef . Also their colour was lighter, less red and more yellow and they had the lowest flavor intensity and overall acceptability. 相似文献

ABSTRACT: The effectiveness of whey protein isolate (WPI) solution as a postbreading dip to reduce oil absorption in deep‐fried, battered, and breaded chicken patties was investigated. Chicken patties were battered, breaded with either crackermeal or Japanese breadcrumbs, and dipped in WPI solutions prepared at 4 different protein concentrations (0%, 2.5%, 5%, and 10%, w/w WPI) that were adjusted to pHs 2, 3, and 8 before being deep fried. Undipped chicken patties served as the control. Overall, the most effective treatment was observed for WPI solutions made at high concentrations (5% and 10% WPI) at low pH levels (pHs 2 and 3). The highest lipid reduction observed for crackermeal patties (CMP) was 31.2% for patties treated with 5% protein solutions at pH 2 while the highest lipid reduction for Japanese breadcrumb patties (JBP) was 37.5% for patties treated with 10% protein solutions at pH 2. Oil degradation and batter, breading, and whey pickup did not significantly affect final lipid and moisture content. Moisture content was generally lower in patties treated at low pH levels (pHs 2 and 3). The results indicate that the usage of WPI as a postbreading dip is a promising alternative in reducing fat content in fried foods since it could simultaneously fulfill the steady demand for fried foods and contribute to the growing effort of Americans to consume less fat. 相似文献

Four breakfast sausage formulations were prepared to contain: (1) chicken lean + chicken fat (CF), (2) chicken lean + beef fat (BF), (3) chicken lean + pork fat (PF), or (4) chicken lean + high-oleic pork fat (PO). Formulations were targeted to contain 15% fat. Acceptability, tenderness, juiciness and flavor scores for each of the formulations as measured by a consumer taste panel (n = 71), were not different (P> 0.05). Sausages prepared with CF had a higher (P < 0.05) cooking loss and lower fat content than those prepared with BF. Thibarbituric acid (TBA) values for PO were significantly lower than those containing BF, PF, or CF. Sausage products containing chicken fat exhibited the highest TBA values during 9 days of storage at 4°C. These results suggested that chicken, beef, pork or high-oleic fats can be used as the fat source in low-fat chicken breakfast sausages without affecting the product acceptability. 相似文献

Muscle types and collagen, fat, and muscle protein minus collagen were varied in cooked frankfurter-type sausages made from beef and pork meat as well as pork backfat. The content of collagen was fixed at preset levels with pork rind. The amount of total muscle protein in the sausages varied between 5.9% and 11.9% and the fat between 16.1% and 22.1%. The collagen content varied between 1.3% and 4%. Spectroscopic measurements (near-infrared reflectance spectra 1100 to 2500 nm; front-face autofluorescence emission spectra 360 to 640 nm) on raw batters were used to predict the amounts of total muscle protein minus collagen, collagen, myoglobin, and fat (biochemical components), L* values from a Minolta chromameter, and firmness of cold (22 degrees C) and reheated sausages (60 degrees C). Lightness of sausages was most accurately determined from the batter data with a Minolta chromameter or the autofluorescence measurement system. Firmness of cold sausages could be described by the amounts of biochemical components plus the type of muscle used in the sausage. The 2nd-best approach was to use the shape of the near-infrared spectra to determine firmness. This was possible as the shape of near-infrared spectra depended on total protein content, and total protein content largely determined the firmness of cold sausages. If the sausages were reheated to 60 degrees C, near-infrared spectroscopy alone determined firmness of the sausages with a lower accuracy than a combined solution of fluorescence and near-infrared spectroscopy. The 2 spectroscopic techniques could thus be used to estimate the amount of biochemical components in sausages. Once these components were known, firmness could be calculated from a model between the amounts of biochemical components and firmness. For reheated sausages, as opposed to cold ones, there was a need to differentiate between collagen and the other muscle proteins in order to determine firmness. This was optimally achieved by using both autofluorescence and near-infrared spectroscopy. 相似文献

High consumption of processed red meat can cause health issues. Therefore, production of high‐quality meat‐free food alternatives is necessary. The main objective of this study was to use hydrocolloids including κ‐carrageenan, konjac mannan and xanthan gum at 0, 0.3, 0.6, 1.0 and 1.5% w/w to improve the quality of meat‐free sausages formulated by soy protein isolated, texturised soy protein, corn starch, vegetable oil and spices. With the addition of the tested hydrocolloids, the lightness of the sausages improved. κ‐Carrageenan and konjac mannan significantly improved the water‐holding capacity and texture and reduced the cooking loss of the samples, while xanthan gum showed no considerable effect on these parameters. Konjac mannan and κ‐carrageenan (up to 0.6%) improved the general acceptability of the sausages, while inclusion of xanthan gum made no significant difference. Unlike xanthan gum, κ‐carrageenan followed by konjac mannan was highly successful in improving the overall quality of meat‐free sausages. 相似文献

The possibility of using fluid whey to replace ice in frankfurter formulation was studied and some technological, chemical and sensory quality properties of these sausages were determined. Results showed no statistically significant differences in most technological, chemical and sensory parameters determined. However, emulsion stability rate was significantly increased by liquid whey addition to the formulation. A slight increase in ash content and pH value was also observed with liquid whey addition. Even 100% whey replacement did not produce any adverse effects in cooked sausage sensory properties. Present results suggest natural fresh liquid whey can be added to frankfurter-type sausage formulations to improve the environment by utilizing a valuable animal product, often wasted, to create a valuable food product at minimal cost. 相似文献

Effect of fat level and partial replacement of pork backfat with olive oil on processing and quality characteristics of fermented sausages 总被引:1,自引:0,他引:1
Six formulations of dry fermented sausages were produced in three replications with three initial fat levels (30, 20 and 10%) and two levels (0 and 20%) of pork backfat replacing olive oil. After 4 weeks of fermentation and ripening the fat content of the treatments with 30, 20 and 10% fat level ranged from 38.86 to 43.60%, 25.56 to 26.86% and 19.01 to 20.14%, respectively. Fat level affected (P<0.05) the weight losses, the chemical composition, the Gram −ve bacterial count, the lightness, the texture and the appearance of fermented sausages. Replacing 20% of pork backfat by olive oil affected (P<0.05) the lightness and yellowness of sausages. Fat-reduced sausages without olive oil and low-fat sausages with olive oil had the highest score for odour and taste. However, the appearance of fat-reduced sausages was just acceptable while that of low-fat sausages was unacceptable, because the surface was intensively wrinkled and case hardening had developed. Further research is needed to improve the appearance of these sausages. 相似文献

BACKGROUND: The effects of modified waxy maize starch (MWMS, 10–32.5 g kg?1) as a replacement for varying levels of oil or both oil and wheat flour (WF) on the chemical and technological characteristics of 60% beef sausages were investigated. RESULTS: Addition of MWMS increased water‐holding capacity and decreased moisture content and both cooking and purge losses. Incorporation of MWMS improved organoleptic acceptance compared with control sausages. CONCLUSION: Sausage formula 5 (F5), containing 20 g kg?1 MWMS and 50 g kg?1 WF, was better (P < 0.05) than all other formulae. The total caloric content of the sausages decreased significantly with decreasing fat level (P < 0.05); for example, the decrease in fat content of 57.4% in F5 led to a significant decrease in energy value of 34.9% (P < 0.05).
