Abstract
Purpose
This study aims to evaluate the effect of oat meal on the quality characteristics of restructured spent hen meat blocks. Spent hen meat is considered as poor because of comparatively higher toughness and less juiciness.
Design/methodology/approach
Oat meal (1:1 hydration, w/w) was incorporated at the levels of 4, 6 and 8 per cent by replacing the lean meat in prestandardized restructured spent hen meat blocks formulation and assessed for physico-chemical and sensory quality.
Findings
The product yield and pH of restructured spent hen meat blocks (RSHMB) were significantly higher at 8 per cent oat meal as compared to control. Shear force values of RSHMB with various levels of oat meal incorporation were significantly lower than control. There were no significant differences in the general appearance, texture, binding, juiciness and overall acceptability scores of RSHMB with different levels of oat meal and control. However, there was a marginal increase in binding and juiciness of RSHMB with increase in the level of oat meal. The optimum incorporation level of oat meal in RSHMB was adjudged as 8 per cent, which also resulted in reduction of production cost by Rs. 14.4/kg as compared to control.
Research limitations/implications
The trials can be further carried to evaluate the storage stability of developed RSHMB.
Originality/value
The paper has demonstrated potential of oat meal as an extender in the development of RSHMB, which also reduced the cost of production.

Abstract
Purpose
The purpose of this study was to explore the potential of Aloe vera as a novel source of natural antioxidant and preservative in the muscle foods and to evaluate the effect of Aloe vera on the storage quality of aerobically packaged chicken nuggets.
Design/methodology/approach
The Aloe vera pulp was incorporated at various levels, namely, 0, 5, 10 and 15 per cent, replacing lean meat in the formulation. The products were analyzed for proximate composition, physicochemical and sensory parameters. Chicken nuggets incorporated with optimum level of Aloe vera (10 per cent) along with control nuggets (0 per cent Aloe vera) were aerobically packaged and assessed for lipid oxidation, physicochemical and microbiological characteristics under refrigerated (4°C) conditions.
Findings
pH, crude protein, ether extract and ash content of the nuggets showed significant (p < 0.05) decreasing trend with increasing levels of Aloe vera; however, there was a significant (p < 0.05) increase in the moisture content, emulsion stability and cooking yield. Aloe vera-enriched nuggets showed significantly (p < 0.05) lower values than control nuggets for almost all the lipid oxidation and microbiological parameters, i.e. free fatty acid, thiobarbituric acid-reactive substances value, total plate count, psychrophillic count and yeast and mould count. No significant (p > 0.05) difference was observed in the sensory parameters of the Aloe vera-enriched nuggets and the control samples throughout the period of storage.
Originality/value
The paper has demonstrated the use of Aloe vera as a potential natural antioxidant without any marginal decline in the sensorial characteristics and nutritive value of the muscle foods.

This paper aims to standardize level of spent hen meat powder incorporation in whole wheat bread without affecting the bread structure.
Abstract
Purpose
This paper aims to standardize level of spent hen meat powder incorporation in whole wheat bread without affecting the bread structure.
Design/methodology/approach
Spent hen meat powder at 20, 30 and 40 per cent level was used for substitution of whole wheat flour.
Findings
The results revealed that increasing the level of meat powder brought about significant (p < 0.05) effect on physicochemical parameters, proximate composition, textural profile and instrumental colour values (except hue). The pH, baking loss, carbohydrate content, energy and moisture protein ratio decreased significantly (p < 0.05) with meat powder incorporation. Whereas, moisture, protein, fat, ash and moisture retention values increased significantly (p < 0.05) with whole wheat substitution. Meat powder addition increased all the textural profile parameters significantly (p < 0.05). Redness, yellowness and chroma values also increased significantly (p < 0.05) with replacement of whole wheat flour. Sensory evaluation showed variable effect of higher meat powder incorporation. The colour of crust, crumb and flavour evinced significant (p < 0.05) increase with level of incorporation, while porosity and texture decreased significantly (p < 0.05). The overall acceptability of 30 per cent replacement was the highest.
Research limitations/implications
Storage stability and preservation aspect can be further explored for better shelf life at ambient temperature.
Practical implications
The development of such a product would definitely be profitable to the poultry industry by opening new avenues for under-used spent hen meat and meat processors.
Social implications
Addition of meat not only channels better utilization of spent hen meat but also enhances economical return to farmers and the meat industry; it also helps in accomplishing protein requirement of consumers.
Originality/value
The addition of spent hen meat enhanced the physico-chemical and sensory attributes of the treated groups than control. It is a novel nutritionally rich alternative for regular breads.

Abstract
Purpose
The purpose of the study was to produce a healthier, convenient and traditional ready-to-eat (RTE) snack option with increased nutritional value, using spent hen meat, dietary fibre (DF) and simple technological methods. The product was designed to be stable without refrigeration and be easily adoptable by local self-help groups, rural women and youth and entrepreneurs in urban and semi-urban areas.
Design/methodology/approach
Conventional binder used for making snacks, i.e. rice flour was partially replaced by different sources of antioxidant DFs, i.e. oat flour (T1 – 10%), finger millet flour (T2 – 5%) and amaranth flour (T3 –15%) to prepare spent hen snack sticks (SHSS). The snacks were then packaged in low density polyethylene (LDPE) pouches and evaluated for their storage stability at ambient temperature for a period of 35 days. Their physico-chemical, sensory and microbiological quality was evaluated at a regular interval of 7 days. The proximate composition of developed SHSS was compared to commercially available snack products (chakli/murukku – snacks without meat).
Findings
The fibre-enriched SHSS showed significant improvement in nutritive value, as they contained more fibre (p = 0.001) and protein (p = 0.029) than control SHSS. When compared to commercially available snack product SHSS showed three-fold significant increase in protein (p = 0.000) and ash content (p = 0.001) and only 11%–12% total fat as compared to 31% fat in the market-available product. The most acceptable treatment in terms of overall sensory quality and nutritional aspects was T3; however, T2 was more shelf-stable during the storage period. The study showed that fibre-enriched snacks can be stored at ambient temperature for up to 35 days without substantial loss in physico-chemical, sensory and microbial quality. Hence, substituting rice flour with DFs can lead to the development of products with better sensory attributes and improved functionality.
Social implications
The simplicity of the product in terms of composition, machinery and low production costs makes it an easily adoptable one by small-scale entrepreneurs, especially those belonging to semi-urban areas.
Originality/value
Incorporation of spent hen meat, a relatively cheap but abundant source of protein, in RTE products can serve as an effective way to alleviate protein malnutrition, whereas addition of fibre further improves the functionality of the product. The methodology can be easily taken up by small-scale entrepreneurs and create a market for snack-based functional meat products.

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.
Abstract
Purpose
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.
Design/methodology/approach
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.
Findings
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.
Research limitations/implications
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.
Practical implications
Spent hen meat utilization can done with greater efficiency by using such techniques in meat caterings.
Originality/value
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 is to produce spent hen tikka of improved quality attributes using lemon juice and ginger extract marination.
Abstract
Purpose
The purpose of this study is to produce spent hen tikka of improved quality attributes using lemon juice and ginger extract marination.
Design/methodology/approach
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.
Findings
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.
Research limitations/implications
Future research may be carried out to assess the effect of lemon juice and ginger extract marination on mineral content and lipid profile.
Originality/value
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.

Abstract
Purpose
The aim of this work was to study the effect of aerobic packaging on storage quality of functional restructured spent hen meat slices (FRSHMS) at refrigerated temperature (4 ± 1°C).
Design/methodology/approach
FRSHMS were prepared by replacing the lean meat with different binders and extenders in pre-standardized restructured spent hen meat slices formulation. The slices of control and FRSHMS were aerobically packaged in LDPE and analyzed for physicochemical, microbiological and sensory quality.
Findings
The pH of FRSHMS was significantly higher (p = 0.03) than control on 0 and 7th day. Thiobarbituric acid (TBA) values of both control and FRSHMS increased significantly on 21st day of storage as compared to 0 day. TBA value of FRSHMS was significantly lower (p = 0.04) as compared to that of control on 21st day. Psychrophils were detected on 14th day of storage and thereafter increased significantly (p = 0.00) in both control and FRSHMS. Coliforms were detected only on 21st day of storage in both control and FRSHMS. The sensory attributes of control, and FRSHMS were affected from 14th day onwards, but the products remained quite acceptable with sensory rating between good to very good up to 21 days during refrigerated storage.
Research limitations/implications
The trials can be further carried in modified atmospheric packaging to evaluate storage stability of developed restructured spent hen meat slices.
Originality/value
The paper has demonstrated that the FRSHMS could be stored safely in aerobic packaging for 21 days at refrigeration temperature.

Abstract
Purpose
The primary objective was to determine the prevalence of indicator microorganisms [Staphylococcus aureus, non-S. aureus staphylococci (NSAS), coliforms and aerobic bacteria] for contamination of chicken carcasses, carcass drip and rinse water from the informal chicken market in Gauteng, South Africa.
Design/methodology/approach
Chicken swabs, chicken drips and rinse waters were collected from 151 chickens from 47 random outlets. Pre-tested questionnaires were administered to capture the risk factors for bacterial contamination. Standard microbiological procedures were conducted for isolation and enumeration of target bacteria.
Findings
NSAS (64% and 41%) and S. aureus (12% and 31%) were prevalent on carcasses and in carcass drip respectively. Coliforms (62%) and aerobic bacteria (85%) were detected in rinse water. Significant risk factors for contamination of carcasses with NSAS, S. aureus and coliform organisms were: evisceration of chickens on the same location used for sale, cleaning of display counter with dirty clothes/wipes, holding of differently sourced chickens in the same cage prior to slaughter, not cleaning the display table/counter and hands at all, washing knives in rinse water, high turnover of daily slaughter and length of time to display chickens.
Research limitations/implications
The limitations of this research were the limited geographical coverage and small sample size.
Practical implications
The isolation of these indicator microorganisms suggests the potential presence of other chicken-borne pathogens not tested for in the study.
Social implications
The findings serve to inform policy on public health and street-vended food and can guide control on good sanitary practices.
Originality/value
This is the first comprehensive report on ready to eat chickens from the informal markets in Gauteng, South Africa.

Abstract
Purpose
This present study was conducted to evaluate the effect of different cooking methods on quality characteristics of turkey meat cutlets, i.e. turkey meat cutlets prepared by deep frying (DF), turkey meat cutlets prepared by shallow frying (SF), turkey meat cutlets prepared by microwave cooking at 740 MHz for 20 min (MW) and turkey meat cutlets prepared by microwave cooking at 740 MHz for 10 min followed by shallow frying (MS).
Design/methodology/approach
Several preliminary trials were conducted to optimise the formulation, and finally, turkey meat cutlets were prepared, as per the method followed by Singh et al. (2015). These standardised turkey meat cutlets were cooked with four different cooking methods. The best formulation and optimum cooking method were selected on the basis of physicochemical properties and sensory evaluation.
Findings
pH and moisture content of MW were significantly (P < 0.03) higher than DF, SF and MS; however, cooking yield and water activity values of MW and MS were significantly (P < 0.05) higher. DF had significantly (P < 0.02) higher fat content than SF > MS > MW. The values of textural parameters were significantly (P < 0.01) higher in DF, whereas lightness values of MW and redness values of DF were significantly (P < 0.02) higher. Scores of various sensory attributes, including overall acceptability, were significantly (P < 0.03) higher in MS. Therefore, MS – turkey meat cutlets prepared by microwave cooking at 740 MHz for 10 min followed by shallow frying were found optimum.
Originality/value
Cooking methods vary according to the choice and flavour of the consumer. Meat products, especially cutlets, can be cooked with many cooking methods, but it is always good to choose the one method which contains less fat per cent as per the requirement of present-day health-conscious consumer and also retains and add on to the taste of the product. Hence, microwave cooking followed by shallow frying was found as such a cooking method that has the characteristics of both, i.e. less fat content and also is tasty to the tongue.

Abstract
The terms are not synonymous; their differences are mainly of function and areas of administration. Community Health is used in national health service law; environmental health to describe the residuum of health functions remaining with local authorities after the first NHS/Local Government reorganization of 1974. Previously, they were all embraced in the term public health, known for a century or more, with little attention to divisions and in the field of administration, all local authority between county and district councils. In the dichotomy created by the reorganization, the personal health services, including the ambulance service, may have dove‐tailed into the national health service, but for the remaining functions, there was a situation of unreality, which has persisted. It is difficult to know where community health and environmental health begin and end. From the outside, the unreality may be more apparent than real. The Royal Commission on the NHS in their Report of last year state that leaving environmental health services with local authorities “does not seem to have caused any problems”—and this, despite the disparity in status of the area health authority and the bottom tier, local councils.
