Abstract Pork is the most popular meat in the world. Unfortunately, the selection pressure focused on high meat content led to a reduction in pork quality. The present study used RNA-seq technology to identify metabolic process genes related to pork quality traits and fat deposition. Differentially expressed genes (DEGs) were identified between pigs of Pulawska and Polish Landrace breeds for two the most important muscles (semimembranosus and longissimus dorsi). A total of 71 significant DEGs were reported: 15 for longissimus dorsi and 56 for semimembranosus muscles. The genes overexpressed in Pulawska pigs were involved in lipid metabolism (APOD, LXRA, LIPE, AP2B1, ENSSSCG00000028753 and OAS2) and proteolysis (CST6, CTSD, ISG15 and UCHL1). In Polish...

Autores: Moretti,Celso Luiz; Araújo,Alessandra L.; Marouelli,Waldir Aparecido; Silva,Washington Luiz C.
Tomato (Lycopersicon esculentum Mill.) fruits, cv. Santa Clara, were harvested at the breaker stage from commercial fields in Brazlândia, Brazil, to investigate the ability of 1-methylcyclopropene (1-MCP) to retard tomato fruit ripening. Fruit without external blemishes were graded for size (diameter = 80±5 mm) and mass (m = 130±10 g), placed inside hermetically sealed boxes, and 1-MCP was applied for 12 hours (T = 22±1°C; RH = 80-85%) at four different concentrations: 0 (control), 250, 500 and 1000 mL.L-1. Fruits were held at ambient conditions (T = 23±2°C; RH 80-85%) for 2 days and then stored inside a cold room (T = 20±1°C; RH = 85-95%). Every 3 days, during a 15-day period, fruits were analyzed for firmness, total soluble solids, titratable acidity,...

Provedor de dados: Pesquisa Agropecuária Brasileira
Autores: Argenta,Luiz Carlos; Krammes,Juliana Golin; Megguer,Clarice Aparecida; Amarante,Cassandro Vidal Talamini; Mattheis,James.
The inhibition of ethylene action by 1-methylcyclopropene (1-MCP) extends shelf and storage life of many climacteric fruits. However, 1-MCP appears to have limited effects on stone fruit depending on specie and cultivar. The effects of 1-MCP on ripening and quality of 'Laetitia' plums were determined during ripening at 23ºC following harvest and cold storage. Japanese plums (Prunus salicina, cv. Laetitia) were harvested at mature pre-climacteric stage, cooled to 2ºC within 36 hours of harvest and then treated with 0, 0.05, 0.10, 0.50 or 1.00 muL L-1 of 1-MCP at 1°C for 24 hours. Following treatment, fruits were either held at 23ºC for 16 days or stored at 1ºC for 50 days. Fruits were removed from cold storage at 10-day intervals and allowed to ripe at 23°C...

Provedor de dados: Revista Brasileira de Fruticultura
Autores: Cavalini,Flavia Cristina; Jacomino,Angelo Pedro; Lochoski,Michele Antonio; Kluge,Ricardo Alfredo; Ortega,Edwin Moisés Marcos.
Harvest time is one of the main factors related to guava fruit postharvest losses. It is subjectively determined by fruit size and skin color, without any consensual standardization among the growers. The use of maturity indexes enables growers to know the ideal harvest time according to each market situation. The objective of this work was to determine the maturity indexes to identify the harvest time for guava fruit cv. Kumagai and Paluma. Skin color, fruit firmness, soluble solids, titratable acidity, ratio and ascorbic acid were analyzed. The most adequate maturity indexes for 'Kumagai' guava fruit were skin color and pulp firmness, while for 'Paluma' guava fruit, the best indexes were skin color, pulp firmness, titratable acidity and ratio.

Provedor de dados: Scientia Agricola
Autores: Kluge,Ricardo Alfredo; Jacomino,Angelo Pedro.
Peaches [Prunus persica (L.) Bastch] present reduced post-harvest shelf life, partially, due to their high respiratory rate and fast ripening. These processes are related to ethylene production, as well as its action. Peaches, cv. Aurora-1, were picked at two different ripening stages (mature green and ripe) and treated with 1-methylcyclopropene (1-MCP), the ethylene's competitive antagonist, at concentrations of 0, 100, 300 and 900 nL L-1 for 12 hours at 25ºC. After treatment, the fruits were stored at room temperature (25ºC) for six days. Fruits treated with 1-MCP presented better firmness and less ground color loss than non-treated fruits. The 1-MCP antagonist reduced the development of fruit rot at the mature green stage, but not at the ripe one. The...

Provedor de dados: Agrociencia
Autores: Mena-Violante,Hortencia G.; Cruz-Hernández,Adrés; Paredes-López,Octavio; Gómez-Lim,Miguel Á.; Olalde-Portugal,Víctor.
Bacillus subtilis BEB-13bs, a plant growth promoting rhizobacteria, has improved tomato firmness. Since firmer fruits are be expected to be more resistant to spoilage microorganisms and to have a longer shelf-life, root inoculation with this strain could be an alternative to extend tomato shelf-life. Thus, fruit texture-related changes were studied in tomato plants (Lycopersicon esculentum Mill.) inoculated with Bacillus subtilis BEB-13bs. Treatments were: 1) non-inoculated control treatment (CTL); 2) PGPR inoculated treatment (BS13). Evaluation was made at different ripening stages. Pericarp firmness and activity of poligalacturonase (PG), the major cell wall polyuronide degrading enzyme in tomato, were measured. The expression pattern of ripening-related...

Provedor de dados: Brazilian Archives of Biology and Technology
Autores: Benassi,Guilherme; Correa,Guilherme Augusto Simões Francischini; Kluge,Ricardo Alfredo; Jacomino,Angelo Pedro.
Custard apple (Annona squamosa L.) presents very short storage life at room temperature, in part due to heavy losses in firmness. This process is associated with the production and action of the hormone ethylene. In order to retard the ripening evolution in custard apple, fruits were treated with the competitive ethylene antagonist 1-methycyclopropene (1-MCP) at concentrations of 0, 30, 90, 270 or 810 nL L-1 for 12 h at 25ºC and then stored at 25ºC for four days. The soluble solids content (SSC), firmness and percentage of ripe fruits (firmness &lt; 0.5kg) were determined during the experimental period. There were no differences among treatments as to the SSC. Fruits treated with 810 nL L-1 of 1-MCP showed higher firmness than the control fruits. Both ,...

Some physicochemical and cooking characteristics corresponding to different varieties and commercial samples of rice were analysed. Some mechanical properties determined by both, the viscoelastograf and the Instrom Universal Food Testing Machine were also analysed. Gelatinization time (Gt), gelatinization endotherm and amylose content were determined. The results showed that there was a very good correlation between gelatinization temperature and Gt, while no noticeable correlation among others phsycochemical characteristics was observed. Regarding the mechanical properties, both methods permited to show significant differences among most of the samples. However, when the samples order obtained with hardness (Instrom) values was compared with that...

Autores: Krarup,Christian; Jacob,Cristián; Contreras,Samuel.
The choice of the appropriate cultivar is a critical factor for obtaining a successful crop and for satisfying the needs of the industry and consumers. Nine commonly used or recently available varieties of cantaloupe melons (Cucumis melo L. Group Cantalupensis) were evaluated in two locations with the objective of selecting cultivars ad hoc for processing as fresh-cut cubes. Overall, the yield (30 to 45 t ha-1) and quality, including mainly the fruit size and soluble solids concentration (SSC), varied between locations, but the relative performance of cultivars was similar. The cultivars showed significant differences in attributes that are relevant for the industry and the consumer: color (from yellow to deep orange), SSC (from 8.7 to 14.7%), firmness...

Recently, plant growth regulators have been used for various purposes in apples. Methyl jasmonate (MeJA) has significant effects on the physiology, postharvest biology, processing, and chemical composition of apples. In the present study, the effects of MeJAMeJa treatments on the physicochemical quality and bioactive compounds (total antioxidant activity, total phenolics, and total anthocyanins) of 'Fuji' apples were investigated. The following doses of MeJa were used: 0 (control); 1; 120; 2,240; and 4,480 mg L-1. The highest geometric mean diameter, fruit mass, flesh firmness and skin thickness were obtained from the 2,240 mg L-1 MeJA treatment. Fruits harvested from control trees exhibited the highest total soluble solids content (TSSC) and pH, whereas...

Autores: Thomas,Ariela Betsy; Pires,Caroline Roberta Freitas; Lima,Luiz Carlos de Oliveira.
The need for a permanent market supply of fresh fruit has generated great interest in postharvest techniques that can promote useful life and quality of the fruit. The aim of this study was to evaluate the efficiency of atmospheric modification using different polymeric films in maintaining postharvest quality and prolonging the shelf life of Eva (Mallus sp) apples. For this, fruits from the city of Barbacena - MG, selected and sanitized were packed in plastic trays and wrapped in the corresponding films. The films used were: polypropylene - 20 µm, low-density polyethylene - 14 µm and high-density polyethylene - 7 µm. Another group of fruits (control) was not submitted to a modified atmosphere. Subsequently, all the the packages were stored under...

The goal of this work was to evaluate the effect of different storage temperatures on the quality maintenance of fresh-cut 'Fortuna' avocado (Persea americana Mill.). The fruit was selected, washed and sanitized with sodium hypochlorite solution (190 ppm total residual chlorinee) for 15 minutes. After that, the tip was cut and the fruit was also cut in halves, peeled and the pit removed, manually. Then the halves were immersed in 0.5% calcium chlorite + 0.5% cysteine solution for 2 minutes, to avoid darkening and packed in rigid plastic covered with 20 micrometer thick plastic wrap (PVC film) with a permeability to O2, CO2 and water vapor of 15,000, 80,000 and 390 cm³/m²/day, respectively. The product was stored under 3 different temperatures 0, 5, 10ºC...

Provedor de dados: Ciência e Agrotecnologia
Autores: Luengo,Rita de Fátima Alves; Calbo,Adonai Gimenez; Jacomino,Angelo Pedro.
Wood boxes kind "k" are the most used in table tomato (Lycopersicon esculentum P. Miller) commercialization in Brazil. Due to the fruit accommodation process that occurs during the transport from the production place to the commercialization point, producers fill tomato boxes a little bit over its physical capacity, and they close it with wood strips fixed with nails. In order to prevent strips from cracking, it is common to keep them inside water before using, to increase flexibility. When boxes are opened, many fruits are cracked or kneaded in a significant part of their total area, and normally they are thrown away. The purpose of this paper was to quantify the compression tomato fruits are exposed to in consequence of the "k" box fill / closing system....
