| A modificação da atmosfera de armazenagem é uma possibilidade de prolongar a vida pós-colheita de morangos. No presente trabalho, foram avaliadas quatro composições iniciais de atmosferas (3 kPa O2 + 10 kPa CO2; 5 kPa O2 + 15 kPa CO2; 21 kPa O2 + 15 kPa CO2; e ar ambiente) em combinação com diferentes tempos de armazenagem. Morangos (Fragaria x ananassa Duch) cv. Camarosa e Verão foram colhidos e colocados em embalagens de comercialização ainda nas lavouras. No galpão de embalamento, estas embalagens foram envoltas por sacos de polietileno com permeabilidade de 0,21 e 0,14 a 0,15 mL cm-2 hora-1 para O2 e para CO2, respectivamente. O emprego de atmosferas com concentrações iniciais de O2 e CO2, assim como o uso de polietileno contendo apenas ar ambiente,... |

| This study aimed to analyze the cuticle thickness and pattern of epicuticular wax deposition in 'Gala' and 'Galaxy' apple cultivars (Malus domestica Borkh,) from three Brazilian producing areas: Vacaria (RS), Fraiburgo (SC) and São Joaquim (SC) with altitudes of 971, 1,048 and 1,353m, respectively. Harvested fruit were kept under two storage conditions: regular atmosphere (RA) (0 ºC and 90% RH) and controlled atmosphere (CA) (1.5% O2, 2.5% CO2, 0ºC and 90% RH). Cuticle thickness measurements were made using LM and the deposition pattern of epicuticular wax observed with a SEM. Altitude among the apple producing areas was not a factor in deposition pattern of waxes between the cultivars but at higher altitudes, the cuticle was thicker in both the cultivars.... |

| The physical-chemical quality changes in mangaba fruit were studied. The fruit which attained full development at half-ripe stage were harvested and initially stored at 6, 8, 10 and 12±1ºC for four days. After this period, the fruit were transferred to an acclimatized room (24±2ºC) and maintained for five days. For control purposes, recently harvested fruit were stored directly in an acclimatized room (24±2ºC) for six days. After the transfer and storage at 24ºC, fruit were analyzed daily for their vitamin-C, soluble solids (ºBrix), titratable acidity, pH and firmness contents. In fruit directly stored at 24ºC, there was a sharp fall in vitamin C and acid contents. The fruit firmness decrease, after four days of storage, and they turned totally ripe. The... |

| Abstract The aim of this study was to determine chemical, nutritional and microbiological evaluation of whole or gutted meagre stored at 4 ± 1 oC. Whole ungutted (Group A), eviscerated (Group B), beheaded-eviscerated fish (Group C) and fillets (Group D) groups were created for this study. According to fatty acid analysis, it was determined that meagre is rich in PUFA content and the n3/n6 ratio is within the ideal limits. In all 4 groups, obtained from fillets values were the highest in general, quality parameters were found within acceptable limits. Psychrophilic and mesophilic aerobic bacteria counts exceeded the standards for fillet groups on 7th days of storage. According to microbiological analysis, ungutted, beheaded, eviscerated samples were not... |

| Abstract The effect of different concentrations of gelatin (0%, 2.5%, and 5%) and vacuum packaged on the preservation of golden pompano (Trachinotus blochii) fillets stored at 4 °C was studied over 14 days. The results suggested that both the gelatin groups (2.5% and 5%) showed a reduction in deterioration of colour, drip loss and texture compared to the control group (0%). In addition, the gelatin coating caused a slower reduction in the freshness indexes of the fish, such as total volatile base nitrogen (TVB-N), thiobarbituric acid reactive substances (TBARS), total viable counts and pH. During a certain storage period, the gelatin notably prevented the deterioration of the golden pompano fillet at 4 °C. The 5% gelatin group showed the best effect on... |

| Abstract In the present investigation functional, technological, and rheological attributes of probiotic yoghurt were studied during refrigerated storage (4 °C) for 28 days. The different preparations of probiotic yoghurts were made from dahi microflora which was documented as probiotics. Three strains of lactic acid bacteria (LAB) i.e. S. thermophilus (S02FT), L. bulgaricus (TLB06FT) and L. acidophilus (LA06FT) were selected for formulations of probiotic yoghurt. Three sets of probiotic yoghurt including Y1: S02FT and TLB06FT (1:1ratio), Y2: S02FT and TLB06FT (1:2ratio) and Y3: S02FT, TLB06FT and LA06FT (1:1:1 ratio) along with Y0 as a control (non-probiotic strains) were prepared and stored at 4 °C for 28 days. The results showed that technological... |

| Abstract The current study demonstrates that the ultraviolet-B (UV-B) irradiation not only helps in improvement of the red color of the peppers but also reduces their rate of decay. The Capia peppers were harvested at their full red ripe stage and subjected to the UV-B treatment at doses 4.46 kJ m–2 (UV-B 15) and 8.93 kJ m–2 (UV-B 30). Post irradiation, the peppers were packaged and stored at 5 ± 1 °C temperature with 90-95% RH for 49 days. The UV-B treated group showed lower L* values, but higher a* and h° values as compared to the control group. Therefore, it was found that both the doses of UV-B radiations could enhance the quality of red color of the peppers. However, the lower dose (4.46 kJ m-2) was found to be optimal for reducing the decay rate of... |

| ABSTRACT: Normally, it is not recommended the conditioning of gladiolus stems in water during storage or transport. Hydration of petals may accelerate flower opening, even at a low temperature, which compromises quality at marketing moment. However, for this species, neither the effect of prolonged dry cold storage nor its behavior when transferred to water at room temperature has been evaluated. The present study aimed to evaluate the vase life and the rehydration capacity of gladiolus flowers ( Gladiolus grandiflora Hort.) after dry storage at low temperature. Flower stems of cultivars Blue Frost, Gold Field, Traderhorn, and Jester were dry-stored at a temperature of 5 ± 1 ºC and relative humidity of 85% for 12, 24, 36, and 48h. Control stems remained... |

| Different methods in use for cold smoking of salmon affect product yield and quality. The combinations of filleting time (pre or post), salting methods (dry or injection), salting targets (2.5 or 4%) and smoking temperatures (15 or 25 °C) were studied during 6 weeks of 4 °C cold storage. Salting method had the greatest influence on flesh quality. Injection salting led to 15% higher fillet yield, moderate to strong gaping score, softer texture, and paler fish compared with dry salting. Pre-rigor filleting reduced fillet gaping from a moderate to minor score, but only in dry salted fillets. Smoking at 15 °C reduced yield by 0.5% in injected salted fish, compared with 25 °C. The combination of pre-rigor filleting, dry salting and 15 °C smoking temperature... |

| El objetivo del estudio fue evaluar la influencia de coberturas de quitosana en lascas de jamón cocido y jamón Visking envasadas al vacío. En ambos productos se observó un incremento de la acidez, mayor en los productos con coberturas de quitosana. Se produjo un aumento de la dureza con el tiempo, sin que existieran diferencias significativas (p≤0,05) atribuibles a la aplicación de coberturas. Se encontró un efecto favorable de las coberturas de quitosana en cuanto a retardar el desarrollo de los psicrófilos. La calidad sensorial fue el parámetro que más se afectó durante el almacenamiento; en el jamón cocido el sabor se tornó ácido y se observó un exudado lechoso y en el jamón Visking los jueces refirieron olores y sabores atípicos y una disminución... |

| Among other results, it was found that when hake is handied property it maintains good quality levels up to 10 days after catch, irrespective of season. Its total storage life in boxes with ice is approximately two weeks. Although total storage life remained unchanged, it was found that quality levels tended to be significantly higher if overfilling of boxes was avoided, if the fish was gutted immediately after catch, or if hake was stored in containers with seawater. |
