Potential use of fig peel powder as a fat replacer and functional ingredient in beef patties

Enhancement of the nutritional status of beef patties by adding flaxseed flour

The present study evaluated the replacement of beef fat in beef burgers using a tiger nut (Cyperus esculentus L.) oil emulsion, in order to reduce total fat and saturated fatty acids in the studied samples. Three formulations were processed: Control—100% beef fat; tiger nut 50% (TN50)—50% of beef fat replaced using tiger nut oil emulsion and tiger nut 100% (TN100)—100% of beef fat replaced by tiger nut oil emulsion. The physicochemical parameters were affected after fat replacement. Moreover, the protein and fat contents decreased in those sample with tiger nut oil emulsion, thus the formulation TN100 can be considered as “reduced fat content”. Regarding color, an increased L* and b* value parameters was observed after TN100 while the values of a* remained similar to the Control samples. The hardness, cohesiveness, gumminess and chewiness were similar in all formulations. The addition of tiger nut oil emulsion as a substitute for beef fat reduced saturated fat and increased the mono- and polyunsaturated fatty acids. Oleic acid was found to be in highest proportions in burgers. The TN100 samples were considered as acceptable by consumers. Therefore, total replacement of beef fat using tiger nut oil emulsions in beef burger resulted in a well-accepted and healthier meat product with reduced total and saturated fat contents, as well as increased unsaturated fatty acids.

Beef patties are the most popular fast food worldwide, including Malaysia. As long as a beef patty is one of the Malaysians’ favorite western dishes and can be easily found in the high-end western restaurant, so far assessment of the nutrient composition, cooking characteristics and sensory properties of that was important for healthcare aspect. In the current study, the nutritional values of beef patties incorporated with various level of brown rice powder (BRP) (2%, 4% and, 6%) were evaluated. The result of protein content in raw and cooked beef patties incorporated with 6% of BRP demonstrated the highest percentage (17.41% and 17.48%, consequently). Further finding displayed that the lowest fat concentration was recorded in the formulation of 6% BRP and 4% BRP raw and cooked beef patties (12.44% and 11.45%) frequently. On the other hands, the results of moisture content of 4% BRP raw beef patties and 6% BRP cooked beef patty demonstrate that the lowest percentage (61.16% and 54.92%) while the carbohydrate concentration recorded the highest percentage in both formulations. In additional, beef patty formulated with 6%, BRP showed the lowest diameter reduction at 13.33% compared to other treatment. The calorie content of cooked beef patty and cooking yield of all formulations were recorded in the range of 584 kcal/100 g to 594 kcal/100 g and 78.09% to 80.48% accordingly. However, 2% BRP incorporation in beef patty did not change the sensory properties and consumer acceptability of BRP-based beef patties. In conclusion, beef patty formulation of more than 4% BRP in beef patties was effective in improving protein, ash, carbohydrate content and percentage of diameter reduction while reducing fat content.

Interest exists in the manufacture of meat products with added functional ingredients to enhance consumer health. Because experimental evidence suggests that many herbs and spices, particularly those of the Lamiaceae family such as Salvia officinalis L. (sage) and Origanum vulgare L. (oregano), possess a wide range of biological and pharmacological activities, they represent promising functional ingredients for incorporation into meat and meat products. The present study aimed to determine the bioactivity of cooked beef patties that were enriched with or without sage or oregano extracts (1,200 microg/g). Cooked beef patties were subjected to an in vitro digestion procedure, and the resulting micelles isolated from the digested meats were added to human intestinal Caco-2 cells. The antioxidant potential (ferric reducing antioxidant power [FRAP] value) of enriched beef patties was significantly higher than the FRAP value of non-enriched beef patties, both before and after in vitro digestion. Cell viability significantly increased following treatment with certain concentrations of the micelle fractions from digested sage- or oregano-enriched beef patties. Pretreatment with micelles derived from sage- or oregano-enriched beef patties did not significantly protect against cell injury or DNA damage induced by H(2)O(2). However, micelles derived from digested sage-enriched beef patties (10% vol/vol) significantly increased cellular reduced glutathione (GSH) content. In addition, micelles derived from both sage- and oregano-enriched beef patties (10% vol/vol) significantly protected against H(2)O(2)-induced GSH depletion. Thus, it appears that sage and oregano exhibit some bioactivity within a meat system. Our findings suggest that herbal extracts have potential as possible functional ingredients in meat products.

Recently, more and more research has focused on the potential application of emulsion gels as animal fat replacers in meat products due to their unique structures and functional properties. This study investigated the physicochemical, nutritional and sensorial characteristics of the low-fat beef patties formulated with emulsion gels elaborated with chia mucilage and olive oil as pork back fat replacer. Beef patties were made with five different fat replacement levels (20%, 40%, 60%, 80%, 100%). The result showed that with the improvement of the fat substitution level, the moisture content of reformulated patties was increased while the fat and protein content were decreased with respect to the control group. The levels of polyunsaturated fatty acids were increased by up to 36% (fat replacement levels at 100%) and the health indices including the polyunsaturated fatty/saturated fatty acid ratio, atherogenicity index, and thrombogenicity index were modified. In addition, the reformulated patties obtained higher lipid stability than the control sample. Significant differences were found in the sensory evaluation (p > 0.05) between the control group and the total pork backfat replacement treatment, while the sensory properties of partial replacement (below 60%) were similar with respect to the control group. Therefore, the addition of emulsion gels ending up giving the beef patties positive characteristics, the partial replacement of pork backfat by emulsion gels is a viable option for developing a low-fat beef patty. Practical Applications Emulsion gels have a great potential for use to replace animal fat in meat products. With the use of chia mucilage-based emulsion gels, it is possible to produce low fat meat products with healthier fatty acid profile. In our research, an emulsion gel elaborated with chia mucilage and olive oil was used in development of the fat-reduced burger formulation. The use of chia mucilage-based emulsion gel is an ideal strategy to develop a healthy meat source for the human diet without negatively affecting the technological and sensory properties of the products.

The present study was aimed to evaluate the effects of wheat germ oil and wheat bran fiber as fat replacers on quality and stability of low‐fat beef patties. Total five treatments were prepared by employing wheat germ oil (WGO) and wheat bran fiber (WBF). WBF was used at fixed amount of 3% in all treatments except control in conjunction with varying WGO concentrations as follows: 1.5%, 3%, and 4.5%. Prepared raw and cooked beef patties were stored at 4°C, and further analyses were carried out up to 21 days of storage period with intermittent evaluation interval of 7 days. Higher values of TBARS, peroxide, and cholesterol were observed in raw and cooked beef patties in control, whereas minimum values were found in treatment of beef patties prepared with WGO 4.5% + WBF 3%. The physicochemical parameters were observed by pH and hunter color values. pH was higher in cooked patties as compared to beef patties and showed increases with increase in WGO concentration and storage intervals. The sensorial attributes were observed which included different parameters, such as appearance, texture, taste, odor, and overall acceptability. Higher score was given by the panelists to control for both raw and cooked beef patties; however, minimum score for all sensory properties was found in group treated with WGO 4.5% + WBF 3% within acceptable limit. In nutshell, raw and cooked beef patties treated with WGO 4.5% plus WBF 3% showed better quality, stability, and reduced cholesterol content.

This study examines the implications of PEF as an alternative fat replacer on nutritional composition, display storage stability, product quality, and its practical application for beef patties. Four different beef patties were formulated with 0, 2.5, 5.0, and 7.5% PEF. Addition of the PEF in beef patties resulted in a significant increase in moisture, ash, and total dietary fiber while decreasing protein and fat contents. The cooking yield, moisture, and fat retention of the PEF beef patties were significantly higher than the control patty. The tenderness and juiciness scores of the PEF beef patties were significantly increased compared to the control. The lightness and redness values of raw patties were superior to the control during storage time. The amounts of thiobarbituric acid-reactive substances (TBARS) were lower in PEF beef patties than the control patties during 7 days of storage at 4°C. These results suggested that PEF could be used as a natural antioxidant fat replacer in beef patties without losing sensory and visual quality. In addition, the utilization of PEF may improve nutritional values including dietary fiber and display storage stability in beef patties.

Effects of carboxymethyl cellulose (CMC) and microcrystalline cellulose (MCC) as fat replacers on the microstructure and sensory characteristics of fried beef patties

Influence of a gel emulsion containing microalgal oil and a blackthorn (Prunus spinosa L.) branch extract on the antioxidant capacity and acceptability of reduced-fat beef patties

Defatted Lagenaria siceraria seed flour (DLSSF) was obtained from defatted seed cake, dried, and ground through a sieve of 500 μm and characterized. A 2 × 4 factorial design (two flour hydration rates and four fat substitution rates) was used to produce a low-fat beef patty by replacing fat with DLSSF. Beef kidney fat was used to formulate the control sample. Chemical, physical, technological, sensory, and nutritional characteristics of low-fat beef patties manufactured were evaluated. DLSSF contains mainly protein. As fat replacers, DLSSF induces a significant increase in the pH of the raw and cooked patty, the moisture and protein contents, the cooking yield, the cohesion, chewiness, springiness, and lightness of the cooked beef patty with fat substitution rate. There is a decrease in fat content, total calories, water retention capacity, hardness, and redness of the cooked patty with a fat substitution rate. From the sensory analysis, the substitution of fat improves the acceptability of samples. Based on the overall parameters analyzed, DLSSF containing 60% water can be used to produce low-fat beef patty by replacing fat at 100%. From these results, hydrated DLSSF could be an effective method to solve the problems of noncommunicable diseases related to animal fat consumption.

ObjectivesDry-aging has been known to improve eating quality attributes of beef products (in particular unique flavor and/or juiciness). While fat plays an important role in flavor development of aged beef products, the current aging practice (including dry-aging) predominantly deals with whole muscle aging rather than separated fat aging. We hypothesized that dry-aging of beef fat would result in positive impacts on quality characteristics of ground beef patty. If successful, this would be a novel approach of value-adding process of beef fat as a naturally-enhanced flavor ingredient for manufacturing dry-aged ground beef. The objective of this present study was to determine the physicochemical and textural properties of ground beef patties formulated with wet-/dry-aged fat. Materials and MethodsBeef round muscle (M. semimembranosus and semitendinosus) and backfat were collected from beef carcasses at 7 d postmortem. Trimmed beef backfat was randomly assigned into 5 treatment groups as follows; unaged-fat (control), wet-aged fat for 2 wk (2WA) or 4 wk (4WA) and dry-aged fat for 2 wk (2DA) or 4 wk (4DA). Wet-aging of beef fat was performed in a vacuum bag in a chilling room (at 1°C; 80% relative humidity), whereas dry-aging was conducted without any packaging material in the same chilling condition. Beef patties were formulated with 80% round lean and 20% each assigned fat. Proximate composition, display weight loss, cooking loss and texture profile analysis were determined at each manufacturing day. Display color stability by measuring instrumental color and visual discoloration, pH and lipid oxidation (2-thiobarbituric acid reactive substances, TBARS) were performed at the initial and after 5 d of retail display. The experimental design was a completely randomized block design with 3 independent batches, and the PROC Mixed procedure of SAS (SAS Inst. Inc., Cary, NC) was used for data analysis (P 0.05). The addition of aged-fat for 4 wk (4DA or 4WA) resulted in significantly higher hardness, gumminess, and chewiness of beef patties than control. While CIE a* (redness) of beef patties with aged fat was decreased during display storage, beef patties with 4WA showed the most rapid decrease in redness during display (P < 0.05). Similarly, beef patties made with wet-aged fat (2WA and 4WA) showed the most rapid discoloration, whereas beef patties with dry-aged fat maintained little to no discoloration. Furthermore, the highest TBARS value was observed at beef patties with 4WA between the treatments at the end of display (P < 0.05). ConclusionThese results indicate that the addition of dry-aged fat positively impact on color and lipid oxidative stability of beef patties, while resulting in little impact on chemical composition of beef patties. The addition of aged fat for 4 wk increased hardness, gumminess and chewiness of beef patties, regardless of aging method. The follow up analyses including sensory attributes and flavor related chemical compounds would be highly warranted to determine the efficacy of fat dry-aging in meat flavor development.

Beef is the preferred main ingredient for patties due to its high nutritional value; however, it is also a costly commodity. As a result, beef is often adulterated or partially substituted with pork, which can raise ethical and religious concerns. This study aimed to investigate the physicochemical and volatilome characteristics of patties made from beef, pork, and their mixtures at varying ratios, both with and without added seasonings (salt, pepper, and garlic). Physicochemical properties—including proximate composition, water-holding capacity, cooking loss, texture, and color—were analyzed to assess how pork and seasoning additions influence the characteristics of beef patties. Volatilome analysis was performed using solid-phase microextraction (SPME) coupled with gas chromatography–mass spectrometry (GC-MS). Data were analyzed using principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA) to identify volatile compounds affected by the inclusion of pork. The results showed that adding 25% pork and seasoning altered the physicochemical properties of beef patties. These additions also affected the volatilome profiles. Key volatile marker compounds identified included Dimethyl disulfide (beef patties), Naphthalene (mixed patties), and Hexanal (pork patties) in seasoned samples. For unseasoned samples, potential markers were 3,7,11- Trimethyl-1-dodecanol, Hexadecane, and Nonanal for beef patties; Naphthalene, Octanal, and Heptanal for mixed patties; and Hexanal, (E)-2-Octenal, (E)-2-Heptenal, and 2-Pentylfuran for pork patties. These findings demonstrate that both physicochemical and volatilomic analyses are effective tools for distinguishing between patties made from beef, pork, and their mixtures. Future studies should evaluate whether these compositional changes influence the sensory properties of the patties. As a chemical validation, quantification of the identified markers using reference compounds is also required.

This study evaluated chia flour, egg white powder, and peanut oil gelled emulsion (GE) as a fat replacer in beef patties. Four formulations were prepared, replacing beef fat with different levels of gelled emulsion: 0% (C), 50% (G50), 75% (G75), and 100% (G100). The beef patties with GE showed improved nutritional properties, technological parameters, and cooking characteristics. A remarkable reduction in SFAs was achieved with the substitution of beef fat by the GE, with reductions of 33.71%, 46.64%, and 72.04% for 50%, 75%, and 100% substitution levels, respectively. AI and TI indices decreased, indicating healthier profiles. Reformulated samples exhibited lower hardness, gumminess, and chewiness values. Color and appearance were similar to the control, with higher sensory scores for G75 and G100. GE impacted color parameters, increasing L* and b* values. The utilization of GE effectively minimized voids in the beef patty structure, leading to improved cooking yield and a more compact structure. GE influenced oxidative stability, with average onset temperatures of 126.33°C (50% GE), 140.58°C (75% GE), and 127.04°C (100% GE). In conclusion, gelled emulsions could successfully contribute to producing healthier meat products.

The present work aimed at evaluating the Cucurbita maxima Duchesne defatted seeds flour (CDSF) as fat replacer in beef patty. Pastes obtained from CDSF containing 60 and 72 % water were prepared and used to replace fat in beef patty at 25, 50, 75 and 100 % respectively. A control patty was processed using kidney fat from beef. The proximate composition, technological yield, textural and sensorial properties of different samples were evaluated. Results showed that CDSF contains 77.76/100 g proteins based on dried matter. Protein content of patty increased with fat substitution rates (FSR) from 18.82/100 g wet matter (WM) to 23.24/100 g WM respectively for the control (P0) and the sample in which fat was substituted at 100 % with the CDSF paste with a water content of 60 % (P460). The lipid content dropped with the increase in the fat substitution rate and water content of CDSF paste from 10.70/100 to 0.28/100 g WM respectively for the sample in which fat was substituted at 25 % with the CDSF paste with a water content of 60 % (P160) and the sample in which fat was substituted at 100 % with the CDSF paste containing 72 % water (P472). Similarly, hardness dropped from 54.78 N (P0) to 37.56 N (P472) respectively. The cooking yield increased significantly (p < 0.05) with the increase in the water content of the CDSF paste and the fat substitution rate. From the sensory analysis, patties with 75 and 100 % of FSR were the most accepted. Thus, the CDSF paste can be used in beef patty as a fat replacer to reduce the detrimental effect of animal fat consumption.

The effects of replacing tallow with plant oils on the chemical composition, physical properties, fatty acid composition,and sensory properties of beef patties were investigated. Beef patties were produced with seven different formulations: con-trol (tallow, 100%), rice-bran oil replaced (TR) and olive oil replaced (TO) (each at 20%, 40%, and 60% substitution). Fatcontent of beef patties increased, whereas moisture content decreased with increased TR and TO. Beef patties had increasedlightness and yellowness but decreased pH and redness compared to those in the control (p<0.05). The thiobarbituric acidreactive substances (TBARS) values of all beef patties increased during cold storage. The TBARS values in the replaced TRor TO were similar to or lower than those in the control after 3 d. Saturated fatty acid content of beef patties decreased asthe level of TR and TO increased, whereas unsaturated fatty acid content increased. Monounsaturated fatty acids werehigher in TO and polyunsaturated fatty acids were higher in TR. The overall acceptability scores showed no significant dif-ferences between the control and replaced TR or TO over 7 d of storage.Key words: beef patties, rice bran oil, olive oil, fat replacement, fatty acid composition
