The pork was pasteurised in jars in 4 formulations: control (C), with the addition of chilli peppers (CHP), with the addition of sodium ascorbate (SA), and with the addition of butylated hydroxytoluene (BHT), and stored at 5 °C for 50 days. Although the addition of chilli peppers did not slow down lipid oxidation in pork, this product had lower lightness and higher redness and yellowness than the other products. It was also characterised by the lowest hardness and chewiness values. Sensory evaluation revealed that meat with CHP had a less intense fatty flavour and aroma, and no off-flavour or off-odour. This variant was also evaluated as more juicy and soft, and the taste and aroma of chilli peppers were distinctively perceptible throughout storage. Pork with CHP received significantly higher scores for overall quality.

The effect of ginger rhizome, in comparison with sodium ascorbate and butylated hydroxytoluene, and storage time at 5℃ on the quality of pasteurized canned meat was studied. Ginger rhizome was as effective as sodium ascorbate in inhibiting lipid oxidation. The canned meat with ginger rhizome was characterized by a lighter color and a lower contribution of redness than the remaining products. It was also characterized by the lowest hardness, springiness, and chewiness. In a sensory evaluation, meat with ginger rhizome was evaluated as juicier and softer than the remaining meat products. The results of this study indicate that ginger rhizome could be used in the place of synthetic antioxidants in pasteurized canned meat.

Soy corn yoghurt is a vegan friendly product prepared by using soymilk as the major ingredient. The aim of this study was to assess the effect of corn milk addition (0, 10, 20, 25 & 30%) on the quality of soy yoghurt. The samples were subjected to sensory evaluation for consumer acceptability and data were subjected to statistical analysis. From sensory evaluation and statistical analysis 10% corn milk inclusion was selected as the best product (p<0.05). The yoghurt thus prepared using 10% corn milk had total solids 22.04%, moisture content 78.62%, protein 4.84%, fat 3.29%, carbohydrate 12.57%, ash 0.81%, acidity 0.68% and pH 4.58. Both control and 10% corn milk incorporated yoghurts were stored under refrigeration 6±1° C and analyzed at 2 days interval till 10 days. Yoghurts with corn milk and control were organoleptically acceptable up to 10 and 6 days respectively. Acidity and syneresis increased but pH decreased with storage time in both samples.

Pork Patties

The lipid oxidation (LOX) of pork meat has been associated with loss of quality and shorter shelf life. Consequently, synthetic antioxidants have been used to reduce this process, but their use has shown potential health risks. Thus, the use of natural ingredients has been suggested as a strategy to prevent LOX. This study aimed to assess the oxidative stability of pork patties treated with ethanol extract of mesquite leaf (EEML) during storage. Furthermore, the polyphenol composition (TPC, total phenolic, TFC, total flavonoid) and antioxidant activity (antiradical and reducing power activity) of EEML were also evaluated. For this study, five treatments (CN (control), without antioxidant; Asc, ascorbic acid 0.02%; BHT, butylated hydroxytoluene 0.02%; EEML1, 0.05%; and EEML2, 0.1%) of pork patties were applied. Patty samples were stored at 4 °C, and physicochemical parameters, lipid oxidation, total antioxidant capacity of the meat, and sensory analysis were evaluated at 0, 3, 7, and 10 days of storage. EEML presented high values of TPC (278.5 mg gallic acid equivalent (GAE)/g) and TFC (226.8 mg rutin equivalents (RE)/g) levels. The addition of EEML did not modify the chemical composition of the pork patties. On the other hand, colour parameters were affected by the inclusion of EEML in pork patties, presenting the lowest a* in the CN group compared to the other groups after 10 days storage. Lipid oxidation increased during the whole period, showing the lowest (P < 0.05) conjugated dienes and thiobarbituric acid reactive substances (TBARS) values (40% and 90% of inhibition, respectively) compared to the CN group. Regarding sensory analysis, there were no significant differences in colour, appearance, odour, flavour, juiciness, fat sensation, and firmness of the cooked pork patties among treatments. These results suggest that EEML has great potential as a natural antioxidant for meat products.

Avaliou-se a qualidade do suco de laranja pasteurizado exposto à comercialização. Amostras refrigeradas e envasadas em embalagens “TetraPak”, coletadas ao acaso, foram adquiridas no mercado varejista da cidade do Recife, durante o período de Setembro/98 a Julho/99. Foram avaliadas 03 marcas comerciais denominadas A, B e C, perfazendo 60 amostras. Para cada marca comercial, as amostras foram adquiridas em duplicata, sendo uma destinada às análises físicoquímicas (vitamina “C”, acidez total titulável, sólidos solúveis totais e pH) e a outra ao teste de incubação (35 ºC durante 10 dias). As marcas analisadas atenderam ao padrão de qualidade estabelecido pelo Ministério da Agricultura, exceto a marca C. Esta apresentou em 70% das amostras analisadas, teor de sólidos solúveis totais (SST) inferior ao padrão e sinais de deterioração durante o teste de incubação em 10% das amostras, evidenciando falhas no processamento térmico. O processamento asséptico associado ao armazenamento sob refrigeração permitiu que todas as amostras das marcas analisadas apresentassem quantidades de vitamina “C” acima do valor mínimo estabelecido pelo Ministério da Agricultura. Abstract The quality of pasteurized orange juice exposed to commercialization was evaluated. Samples, refrigerated and packed in “TetraPak” randomly collected were bought at the retail trade market of Recife, during the period of September/98 to July/99. Three commercial labels named A, B and C were evaluated, making a total of 60 samples. For each commercial label, the samples were acquired in two replicates, one of which was destined to physicochemical analysis (vitamin C, total acidity, total soluble solids and pH) and the other to the incubation test (35 ºC during 10 days). The labels assayed assisted to the established quality pattern of the Ministry of Agriculture, except the C label. This label presented in 70% of the analyzed samples, lower TSS rates than those considered as standard, it also showed signs of deterioration during the incubation test in 10% of the samples, evidencing flaws in the thermal procedure. The aseptic procedure associated to the refrigerated storage allowed all samples of the assayed labels to show vitamin C levels higher than the minimum established by the Ministry of Agriculture.

This study evaluated the effects on the internal quality of eggs of various storage environments through which eggs may pass between being laid and being consumed. Commercial eggs (N = 648) from Dekalb White hens were used. Treatments consisted of T1: 28 days at 4 °C; T2: 28 days at 20 °C; T3: 7 days at room temperature (27 °C ± 2 °C) (humidity 55%) and 21 days at 4 °C; T4: 7 days at room temperature and 21 days at 20 °C; T5: 14 days at room temperature and 14 days at 4 °C; T6: 14 days at room temperature and 14 days at 20 °C; T7: 21 days at room temperature and 7 days at 4 °C; T8: 21 days at room temperature and 7 days at 20 °C; and T9: 28 days at room temperature. The characteristics that were evaluated consisted of Haugh unit (HU), yolk index (YI), colour (L*, a* and b*), albumen pH, yolk pH and lipid oxidation. Eggs stored 28 days were darker (L*), and had greater yolk pH and lipid oxidation than fresh eggs. Eggs stored under T1 and T3 conditions had greater HU and YI than eggs stored in the other environments. The albumin pH of eggs stored at room temperature (T9) was highest of the treatments. Yellowness was increased in eggs stored under T4, T6, T8, and T9 conditions. Eggs should be stored under refrigeration as this promotes maintenance of internal quality and mitigates negative effects of previous storage conditions.

Abstract Undersized crawfish have little economic value and are often discarded. Producing crawfish minced meat (CMM) from undersized crawfish and using an appropriate freezing technique may enable an economically viable market. The objective of this research was to evaluate the effect of the energy removal rate using two techniques, cryogenic freezing (CF) and air blast freezing (BF), on CMM’s quality during frozen storage. CMM was separated into two batches; one batch was cryogenically frozen with liquid nitrogen and the other batch was frozen with an air blast freezer. CMM batches were frozen and stored at − 18 °C. They were analyzed for moisture content, color, pH, and lipid oxidation during 180 days of storage. The CMM yield was 64.67% of the total crawfish weight. Cryogenic freezing achieved the highest freezing rate. Cryogenically frozen CMM showed 22% less lipid oxidation than CMM frozen by air blast freezing at 180 days of storage. This study showed that CMM could be mechanically produced from undersized crawfish and freezing techniques with high energy removal rate could better maintain quality attributes for CMM during frozen storage.
