The purpose of this study is to produce spent hen tikka of improved quality attributes using lemon juice and ginger extract marination.

Three experimental groups were made: control group, 20 per cent lemon juice marinated group (LM) and 50 per cent ginger extract marinated group (GM). Boneless spent hen breast meat was cut into small cubes of one inch with the help of knife and kept in marinade solution in ratio of 2:1 w/v at 4 ± 1°C for 16 hours in a refrigerator. Chicken tikka was prepared using an electric oven at the temperature of 240°C for 20 minutes.

There was a significant (p < 0.05) increase in moisture content and water holding capacity of LM and GM marinated chicken tikka, whereas protein, fat, ash, cholesterol content and shear force values were significantly (p < 0.05) decreased. pH was significantly (p < 0.05) higher in GM and significantly (p < 0.05) lower in LM compared to control for chicken tikka.

Future research may be carried out to assess the effect of lemon juice and ginger extract marination on mineral content and lipid profile.

Marination of meat with LM and GM improved the sensory scores and textural properties, whereas fat and cholesterol content of chicken tikka decreased. Therefore, marination of chicken tikka with LM and GM may be used as processing technology to improve quality attributes of spent hen tikka.

This study aims to assess the effects of calcium chloride marination on buffalo meat tenderness, instrumental color and palatability traits and to compare the effects with that of aging, so as to suggest a cost-effective tenderizing method to meat retailers.

Buffalo longissimus thoracis (LT) steaks were marinated post-rigor with 200-mM (5 per cent w/w) calcium chloride solution and were subjected to aging at 2-4°C for eight days. The pH, water holding capacity (WHC), cooking loss, color, myofibrillar fragmentation index, Warner–Bratzler shear force and sensory quality attributes were assessed at 1, 2, 4, 6 and 8 days post-mortem. The values were then compared with those of control steaks kept at the same storage conditions.

Marination was not found to affect pH, WHC, cooking loss or color as compared to the control steaks. Tenderness was found to be improved in marinated steaks by 53.44 per cent as against 35.59 per cent in those that aged without marination. The sensory panel evaluation showed that marinated steaks significantly improved (p < 0.01) in the scores for the different attributes, and no flavor problems or alterations in cooked color were noticed.

The animals used in this study fall in the age group of four-eight years with one of them being four years old and the rest above the age of six years. Given the fact that, age-related increase in pyridinoline content of intramuscular collagen and cross-link formation influenced by sex can contribute to the toughness of meat in spent animals (Bosselmann et al., 1995), the variation in age of the animals under study could be regarded as a limitation of the study. But apart from one animal, all of them were more than six years old, forming more or less uniform samples.

This research is of value to the meat industry or retailers. The post-rigor marination of buffalo LT steaks with 200-mM CaCl₂ (5 per cent w/w) appears to be a promising measure from the view of practicability. The relative ease of operation makes it superior to other successful techniques in reducing toughness, such as electrical stimulation.

The aim of the study was to analyse the quality changes in marinated herring meat depending on the moment of adding milk thistle.

One control (C) and two experimental groups were investigated: MH (milk thistle added to a marinade solution) and FH (fillets rubbed with milk thistle before marination). The basic chemical composition, the meat colour, heavy metals concentration, fatty acids profile, quality of lipids and antioxidant capacity were determined.

The occurrence of Fe, Mn, Cu and Zn was higher in the experimental group than in the control group throughout the marinating process. The peroxide value was higher from the first day in the control group than in the experimental groups. On the last day of the study, the peroxide value in the control group exceeded the maximum acceptable value. The highest level of Thiobarbituric Acid Reactive Substances was determined in the control group on the first day, and the lowest in the FH group. On the first day, the highest percentage of DPPH (2,2-Diphenyl-1-picrylhydrazyl) radical quenching was recorded in the FH group.

The results are the first to find that the addition of milk thistle to herring fillets in marinating process maintains or even improves the quality of the marinades. The process of previously coating the fillets in milk thistle and then marinating achieves a lower peroxide value, higher content of polyunsaturated fatty acids and a higher content of elements such as iron and manganese, which are very valuable for human health.

The purpose of this study was to study the effect of kiwifruit juice and tumbling in improving tenderness and to access antioxidant potential of kiwifruit juice.

Three treatment groups were made: Spent hen meat was subjected to still marination (SM) and tumbling marination (TM). This meat was used for preparation of whole muscle chicken nuggets and compared with control (without marination) nuggets (Con). These treatments were subjected to analysis of physicochemical characteristics, textural quality, lipid oxidation and sensory quality.

SM and TM exhibited higher moisture content and lower protein and fat content than Control SM and TM showed significant (p = 0.132) reduction in firmness from 5.1 to 2.3 and 1.2 Kg/cm², respectively, and toughness from 14.1 to 6.2 and 3.3 Kg-sec/cm², respectively, as observed by Warner-Bratzler shear and improvement in texture profile values. Sensory scores for texture, juiciness and overall acceptability were also better for SM and TM. Significant (p = 0.007) reduction was observed in lipid oxidation parameters of SM and TM. Thiobarbituric acid (TBA) values (on 0 day) for SM and TM were 0.18 and 0.15 as compared to 0.28 mg/kg of malonaldehyde for control. Peroxide values (PV) were also lower for SM and TM as 0.44 and 0.33, which were lesser than control (0.62 meq. peroxide/kg). The values for PV, TBA and free fatty acid increased with increase in storage period in all treatment groups. However, the antioxidant activity of kiwifruit juice persisted during whole storage period evidenced by lower values of lipid oxidation parameters for SM and TM than Control at each storage interval.

Further research may be carried out to compare the tenderizing potential of kiwifruit juice with other plant proteases and physical tenderizing techniques. Spent hen meat utilization can be done with greater efficiency by using such techniques in meat caterings.

Spent hen meat utilization can done with greater efficiency by using such techniques in meat caterings.

Marination with kiwifruit juice improved the quality characteristics of chicken nuggets made from spent hen meat without altering its sensory quality. Tumbling was found to be beneficial in enhancing the tenderizing effect. Therefore, marination with kiwifruit juice can be used as a processing technology to use spent hen meat in preparing value added products.

The purpose of this study was to assess the effect of vacuum tumbling and red beetroot juice (RBJ) incorporation on quality characteristics of marinated chicken breast and leg meat cuts.

Vacuum tumbling of breast and leg meat cuts was carried for a duration of 2 h and compared with control (0 h tumbling) and traditionally marinated (6 h) meat cuts. Vacuum-tumbled treatments were also marinated using RBJ in place of water to assess the combined effect of RBJ and vacuum tumbling. All the cuts were cooked in an oven at 170°C for 40 min. Quality characteristics of fresh and refrigerated products were analysed.

Vacuum tumbling for 2 h resulted in a significant (p < 0.05) increase in marinade pickup, water-holding capacity (WHC), cooking yield, moisture and ash content and a significant (p < 0.05) decrease in hardness, gumminess, chewiness and shear press values in both types of meat. Breast meat treatments had significantly (p < 0.05) higher WHC, moisture, protein, cohesiveness and gumminess and significantly lower fat content, hardness and shear press values than leg meat treatments. Control breast and leg meats had marinade pickup of 9.19 and 9.31 per cent and cooking yield of 69.08 and 68.31 per cent, respectively, whereas corresponding values for treated breast and leg meats varied from 11.28 to 11.98 per cent and 73.32 to 74.94 per cent, respectively. Sensory scores declined significantly (p < 0.05) during refrigerated storage. On the 12th day of storage, control breast and leg meat cuts had acceptability scores of around 5.0, whereas all other treatments had acceptability scores between 6.0 and 7.0 on an eight-point scale, with RBJ-treated products having the highest acceptability. All the products were also microbiologically safe up to the 12th day of refrigerated storage.

The research is valuable to meat processors because vacuum tumbling for 2 h using RBJ as marinade can be used in place of 6 h of traditional marination for developing marinated chicken breast and leg meat products.

Meat which has been injected or tumbled with water, salt, sugar and other ingredients, has been available on the Danish market for some decades and is now becoming increasingly common. However, it is not known whether this so‐called neutrally marinated meat will be appropriated by consumers in the long term, or will be destined to be a marginal second rate product. The purpose of this paper is to explore the views of consumers on neutrally marinated meat, including acceptance and potential problems for appropriation.

Four focus group interviews were conducted involving 27 Danish consumers with various socio‐demographic backgrounds.

The interviewed consumers had very little prior knowledge of neutrally marinated meat, and expressed ambivalent attitudes when introduced to it. They had favourable reactions to its taste, texture and robustness and saw the potentially low price as a positive feature. But they also viewed neutrally marinated meat as unnatural, unauthentic and potentially risky to health. Furthermore, concern was expressed due to the lack of information available to consumers and due to suspicion of unfair prices. The focus group interviews also showed that categorisation of neutrally marinated meat in different social contexts is not settled, underlining a sense of ambivalence among consumers. So, even though neutrally marinated meat is being consumed it is unclear if and when conceptual appropriation will take place.

This study provides a broader perspective on consumer perception of new products than found in conventional sensorial tests, including views on the processing, health aspects, ethical aspects and convenience aspects.

The purpose of this paper is to develop a multi‐dimensional, holistic model that: avoids the variable interdependency found in earlier tools; and integrates multiple factors that characterize menu item costs more accurately by considering more than gross profit.

Using data gathered during a three‐month period from three same‐brand units of a full‐service chain restaurant firm, the paper applies data‐envelopment analysis (DEA), a non‐parametric approach that accounts for both controllable (discretionary) and uncontrollable (non‐discretionary) variables, producing a single relative‐to‐best index based on an efficiency rating calculated on a 0 to 1 scale.

The findings suggest that the DEA‐equipped model, which is not constrained by the limitations of traditional matrix approaches, supports a more robust approach by incorporating more cost determinants than traditional menu engineering approaches.

The paper consists of only a single restaurant concept and the evaluation results are purely theoretical. Future research should include the application of the menu analysis recommendations to an actual menu to determine the effectiveness of the model on actual operation profitability.

The research suggests that DEA is an effective tool in the evaluation of a restaurant menu by evaluating individual menu items based on attributes of labor and profitability factors.

The paper shows that by combining DEA with traditional menu analysis methodologies, a more efficient menu analysis tool may be utilized to evaluate menu items without the arbitrary allocation of non‐food costs.

The management of dietary phosphorus in chronic kidney disease patients is an important issue. Phosphorus is often found with protein in foods. However, excessive protein restriction worsens the nutritional status of the patient; thus, phosphorus must be selectively restricted. This study aims to assess the effects of various pretreatments readily available in ordinary households on phosphorus loss in foodstuffs.

This study evaluated the retention of phosphorus in cooked chicken meat (boiled, baked, steamed and microwaved). In addition, this study incorporated various pretreatments (pounding, stabbing, cutting and enzymatic treatment) to the method exhibiting the lowest phosphorus retention (boiling) and assessed the effects on phosphorus retention.

Boiling (65%, vs baking, p < 0.001; vs steaming, p = 0.013; vs microwaving, p = 0.002) of the chicken meat resulted in the lowest phosphorus retention compared to the other cooking methods (baking [89%], steaming [73%] and microwaving [75%]). In addition, stabbing (58%, p = 0.009) or cutting (46%, p < 0.001) further reduced the retention of phosphorus in boiled chicken meat. The retention of phosphorus in enzyme-pretreated boiled chicken was reduced by approximately 10% compared to untreated chicken (p = 0.01). The cooking method that reduced phosphorus retention to the greatest extent was enzyme treatment prior to cutting and boiling.

This paper investigates the effects of common household cooking methods and combinations of methods on the phosphorus content of meat.

YOU may see them sneaking out of the hotel early in the morning, a straggle of self‐conscious corpulent middle‐aged executives heading determinedly for the horizon as fast as a surfeit of expense account eating and a lack of wind will permit. No, they are not dodging the cashier, merely following the Portman's jogging map. This charts three alternative routes through London's Hyde Park and it demonstrates the thoroughness with which this five‐star hotel caters for the business man's every possible needs.

A number of methods are used, or have been proposed, for improving the tenderness of otherwise tough meat. Of these, preparations containing proteolytic enzymes to break down meat proteins are the most widely used. They do work but they cannot turn cowheel into fillet and they cannot imitate adequately the subtle post‐mortem changes that naturally produce top quality meat.
