1. Variability in the shelf life of table grapes from same batch when exposed under different ambient air conditions
Abstract This study aimed to evaluate the effect of the variability in ambient air conditions (temperature and relative humidity) and periods of exposure on the same batch of table grapes in the first stages of the fruit supply chain (harvesting, processing and storage prior to commercialization), in order to predict their dynamic shelf life. To estimate the

3. A DISCRETE STOCHASTIC MODEL TO DETERMINE FOOD QUALITY BY USING SIMULATION: A STRAWBERRY CASE STUDY
ABSTRACT The agri-food supply chain (AFSC) sets a series of challenges in the production, storage, distribution, and transportation processes, as the market's requirements for fresh food combine food quality and safety attributes. This research suggests a discrete event modeling to study the behavior of food quality in all supply chains (SCs) in terms of tem

5. CARACTERIZAÇÃO QUÍMICA E AVALIAÇÃO DA CITOTOXICIDADE DE UM HETEROPOLISSACARÍDEO ISOLADO DA BIOMASSA DO Colletotrichum gloeosporioides
Colletotrichum gloeosporioides biomass was submitted to ethanolic extraction (78 ºC, 12 h) to remove low molecular weight compounds followed by hot aqueous extraction (100 ºC, 4 h, 4x) to obtain polysaccharides. Consecutive freezing/thawing treatments of the aqueous extract yielded a soluble fraction in cold water that was separated on five components (PI

6. Influence of clay surfactants polarity on the crystallization and rheological behavior of nanocomposites of PDLLA
The effect of clay hydrophobicity on the cold crystallization and rheological properties of nanocomposites of poly(D,L-lactic acid) (PDLLA) was investigated. Crystallization was evaluated by DSC for isothermal and non-isothermal conditions. The clay modified with a hydrophilic surfactant acts as a nucleating agent, while the clay modified with a hydrophobic

7. Monocyte Activation Test (MAT) as a possibility of replacement for the rabbit pyrogen test in hyperimmune sera
ABSTRACT The use of a commercial kit for the monocyte-activation test (MAT) was evaluated for assessing pyrogenic contamination of hyperimmune sera . Three batches of sera, two pyrogen free and one pyrogenic, were tested. Endotoxin spike recover indicated that sample dilutions from 1/2 to 1/10 are suitable. Kit transport and storage conditions were also eval

8. Binary Blends of Biodiesel from Macauba (Acromia aculeata) Kernel Oil with Other Biodiesels
Macauba is a palm tree which provides large amount of oil. Particularly its oil from the kernel presents excellent stability to oxidation as it is mainly constituted by saturated organic chains. This stability is inherited by the biodiesel prepared with this oil. Paradoxically, contrarily to the expectation as it is mainly constituted by saturated esters, th

9. Water loss in table grapes: model development and validation under dynamic storage conditions
Abstract Water loss is a critical problem affecting the quality of table grapes. Temperature and relative humidity (RH) are essential in this process. Although mathematical modelling can be applied to measure constant temperature and RH impacts, it is proved that variations in storage conditions are normally encountered in the cold chain. This study proposed

10. The establishment of the time interval between inspections for a cold standby system with component repair
Abstract The time interval between inspections of cold standby systems is a crucial decision to ensure the appropriated system reliability and the lowest costs possible. This paper presents a model developed to establish the optimal time interval between inspections for a two-unit cold standby system with component repair and subject to periodic inspection,

11. Process capability index Cpk for monitoring the thermal performance in the distribution of refrigerated products
Abstract The temperature of refrigerated products along the cold chain must be kept within pre-defined limits to ensure adequate safety levels and high product quality. Because temperature largely influences microbial activities, the continuous monitoring of the time-temperature history over the distribution process usually allows for the adequate control of

12. Molecular detection and antimicrobial resistance of Pseudomonas aeruginosa from houseflies (
Musca domestica ) in IranAbstract Background Pseudomonas aeruginosa is a common bacterium that can cause disease in humans and other animals. This study was conducted to screen for molecular detection and antimicrobial-resistant P. aeruginosa in Musca domestica in different locations in the Iranian provinces of Shahrekord and Isfahan.
