Quality attributes and consumer acceptance of new ready-to-eat frozen restructured chicken

Abstract

The aim of the present study was to develop a new restructured product, cooked and frozen ready-to-eat product that was prepared with boneless chicken meat (breast and drumstick) and mechanically separated chicken meat (MSCM). Non-meat ingredients, such as transglutaminase (TG) and egg albumin powder, were tested to obtain a better strength of adhesion between the meat particles. Five formulations for restructured chicken were developed as follows: T1 (1 % transglutaminase), T2 (1 % transglutaminase and 15 % MSCM), T3 (1 % egg albumin powder), T4 (1 % egg albumin powder and 15 % MSCM) and T5 (1 % transglutaminase, 1 % egg albumin powder and 15 % MSCM). The results of the experiment showed a greater luminosity (L*) in the treatments with TG (T1) and albumin (T3). The treatments without MSCM (T1 and T3) presented significantly lower mean values for redness (a*) when compared to treatments with MSCM (T2, T4 and T5) (p≤0.05). No significant differences were noted between the treatments (p≥0.05) when analyzing the percentage of total saturated fatty acids (SFA), polyunsaturated fatty acids (PUFA) and cholesterol content. Consumer testing showed a high acceptance of the restructured products in all evaluated attributes. Similarly, with regard to the purchase intention, consumers mostly expressed that they would probably or certainly buy the products, for treatments T1, T2, T3 and T5. Moreover, the meat cuts with no commercial value, can transform into new ready-to-eat products that have a high probability of success in the market.

Quality preferences and pricing of fresh-cut salads in Italy: new evidence from market data

“…The available technologies[1] are able to provide microbiologically safe food products having high nutritional quality, similarly to the corresponding fresh product. Consequently, since they do not need any other treatment before being eaten, fresh-cut vegetables can be considered as ready-to-eat products (de Almeida et al , 2015).…”

Rice bran as a substitute for soy protein and erythorbate in chicken nuggets

“…was not detected on the samples, while the coagulase-positive Staphylococcus count was < 10 2 CFU g -1 , and the Coliforms at 45 ºC were < 3 MPN g -1. Similarly, Almeida et al (2015) reported an expected microbiological quality for chicken nuggets (Resolução RDC n. 12, 2001).…”

Preparation, characterization and wound healing effect of alginate/chitosan microcapsules loaded with polysaccharides from Nostoc Commune Vaucher

“…A P-50 probe (long shaft, regular base) was used to perform a two-cycle compression test on the sample. The sample was compressed by the probe to 30% at a speed of 1 mm s −1 , and the initial force was set to 0.5 N [17].…”
