The storage of agricultural products is of great importance in maintaining product quality between harvest and commercialization. The use of numerical and computational techniques, such as the finite element method (FEM) and computational fluid dynamics (CFD), allows the analysis and simulation of systems that involve heat transfer, as is the case of grain storage. A computational model based on these techniques that satisfactorily represents a real system was used to test and to analyze decision alternatives without the need for real experimentation. In this study, we sought to study the behavior of the temperature of a mass of stored mocha coffee beans by using computational techniques, as requested by the private sector. The coffee was stored for 6...

Autores: SANTOS, J. F.; SANCHES, M. F. G.; BARBOSA, R. M.; HENNING, A. A.; VIEIRA, R. D.
O interesse em desenvolver técnicas apropriadas para obter melhores informações sobre o potencial de desempenho de sementes tem sido o foco de diversas pesquisas. O teste de condutividade elétrica (CE) é vantajoso, pois consegue detectar o processo de deterioração mais rapidamente quando comparado a outros, entretanto, este pode não oferecer dados representativos para sementes armazenadas em condições de câmara fria (10 oC). O trabalho teve como objetivo verificar a influência da temperatura de pré-embebição das sementes no teste de condutividade elétrica em soja. Sementes do cultivar BRS 295 foram separadas em duas amostras (com e sem tratamento com carbendazin+thiram) e armazenadas em câmara fria (10 ºC e UR = 65%). O potencial fisiológico das sementes...

ABSTRACT. Numerous factors contribute to specialty coffee quality, storage and cooling conditions. We may therefore assume that sensory evaluation results can be corrupted by measurement errors, especially when cuppers are not trained, leading to occurrence of observation outliers. Therefore, this study aimed to propose simulation scenarios considering parametric values of multilevel model fit with robust adaptive regressions to the presence of outliers in a real experiment with processed and unprocessed coffee beans stored at different times and temperatures. In this context, we considered computationally simulated scenarios in which sensory scoring errors can be made at L = 5 and 10 units. The proposed method was feasible for the sensory scoring of an...

The preservation effect and mechanism of gelatin on golden pompano (Trachinotus blochii) fillets during cold storage
Provedor de dados: Ciência e Tecnologia de Alimentos
Autores: WEI,Peiyu; CAO,Jun; SHEN,Xuanri; LI,Chuan.
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...

Milk is an important source of bioactive compounds. Many of these compounds are released during fermentation and refrigerated storage. The aim of this study was to determine the release of peptides by lactic acid bacteria in commercial fermented milk during refrigerated storage. The size and profile of peptides were analyzed by polyacrylamide gel electrophoresis and sizeexclusion HPLC. During electrophoresis, it was observed that the peptides were released from caseins, whereas β-lactoglobulin was the whey protein with the highest degradation. HPLC analysis confirmed the pattern of peptide formation observed in electrophoresis. Two fractions lower than 2 kDa with aromatic amino acids in their structure were separated. These results were consistent with...

The effects of ultraviolet B (UV-B) irradiation on color quality and decay rate of Capia pepper during postharvest storage
Provedor de dados: Ciência e Tecnologia de Alimentos
Autores: KASIM,Mehmet Ufuk; KASIM,Rezzan.
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...

Provedor de dados: Ciência Rural
Autores: Costa,Lucas Cavalcante da; Araújo,Fernanda Ferreira de; Santos,Mirelle Nayana de Sousa; Lima,Paula Cristina Carvalho; Pereira,Ariana Mota; Finger,Fernando Luiz.
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...

Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Bjornevik, Marit; Cardinal, Mireille; Vallet, Jean-luc; Nicolaisen, Ove; Arnarson, Gudmundur Oern.
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.

Provedor de dados: Ocean Docs: e-repository of  publications
Autores: Ghana Ports and Harbours Authority.
Challenges the fishing ports of Ghana, notably Sekondi Port include the congestion and the deteriorating efficiency due to the increase of users and decreasing quality of catch due to the shortage and ageing of landing facilities, fish handling sheds and ice-making facilities. The Government of Ghana made a request to Japan for an extension of the wharf, construction of additional breakwater, cold storage and ice-making facility at Sekondi Fishing Port in 2010 in order to overcome these challenges. In response the Government of Japan conducted a survey for the project to promote efficiency and improvement of Ghana's fishery sector. The survey was to examine the need, relevance and urgency of the proposed project.

International study on &lt;i&gt;Artemia&lt;/i&gt; : 24. Cold storage of live &lt;i&gt;Artemia&lt;/i&gt; nauplii from various geographical sources: potentials and limits in aquaculture
Provedor de dados: Open Marine Archive
Autores: Léger, P.; Vanhaecke, P.; Sorgeloos, P.
Freshly-hatched &lt;i&gt;Artemia&lt;/i&gt; nauplii from various geographical sources survived storage in a refrigerator (2-4°C) at densities of 2000 per ml and above. Except for &lt;i&gt;Artemia&lt;/i&gt; from Chaplin Lake and Buenos Aires, naupliar viability was very high even after 48 h storage, and did not decrease significantly after a 24 h post-storage transfer to 25°C. Neither the naupliar dry weight nor biochemical composition changed significantly during refrigeration for most strains tested. Comparative culture-tests with stored and freshly-hatched nauplii as food for juvenile marine mysids &lt;i&gt;Mysidopsis bahia&lt;/i&gt; M. and larval carp &lt;i&gt;Cyprinus carpio&lt;/i&gt; L. revealed similar production performances.
