“…A similar finding was reported by Salomão et al (2009) who attributed the different patulin concentration to differences in pH. Other studies reported higher patulin level in 'Fuji' with respect to 'Gala' (Ross et al, 1998).…”

Penicillium expansum is a fungal pathogen of pome fruit, causing the economically important disease of apple blue mould. The fungus is also important due to its ability to produce the mycotoxin patulin. A strain of Aureobasidium spp. (UC14) was assessed for controlling P. expansum and patulin production in a series of in vitro antibiosis experiments. Volatile and non‐volatile metabolites reduced growth of P. expansum on average by 50%. To assess UC14 efficacy on apples in vivo, different concentrations of cellular suspension were assayed. The concentration 1 × 108 cells/mL was the most effective, completely suppressing apple fruits blue mould symptoms. The antagonism of UC14 was further demonstrated by the very low amount of pathogen DNA in treated fruits detected by qPCR. During cold storage, Aureobasidium strain UC14 persisted on fruits and reduced disease severity by 82.5% and 89.8%, for ‘Golden delicious’ and ‘Fuji’ apples, respectively. Aureobasidium strain UC14 reduced patulin on ‘Golden delicious’ and ‘Fuji’ apples by 98.1% and 96.2% with respect to the control, demonstrating good efficacy as a potential biological control agent (BCA), so becoming an interesting candidate for use as BCA in the postharvest phase.

“…In two cultivars of Brazilian apples, Gala and Fiji, inoculated with P. expansum NRRL 1172 or toxigenic P. variabile isolated from apples, and stored for 15 to 90 days at 0 to 25ºC, patulin production was negative until the 30 th day of storage at 0ºC (103). Thereafter and under the other storage conditions, patulin was produced with both Penicillium strains.…”

The number of research papers (128 papers) on mycotoxins published by Brazilian researchers in 1991-2000 surpassed the total number (85 papers) published in the preceding three decades . Thirty percent of the papers surveyed mycotoxins in foods and feeds. AFs in peanut and peanut products continued to be alarming, and high incidence and levels of FBs in corn and corn products also appeared as a serious problem. Contamination with other toxins, such as ZEA, OTA and trichothecenes, was low. Occurrence of AFM 1 in milk and dairy products and patulin in apple juice needs to be verified as the results are somewhat diverging. Work on analytical methods, mycological examination and toxic effects constituted 16, 13 and 13%, respectively, of the published papers in the decade assessed. Attempts to find means of preventing/controlling fungal growth and mycotoxin production notably increased, making up 27% of the papers, including investigations on influencing factors (e.g. genotype resistance, water content/a w , relative humidity, temperature, presence of metals, type of soil, mite infestation) and antagonistic potential of other microorganisms against mycotoxin-producing fungi. Effects of plant extract, flavonoids, fungicides and other chemicals, storage bag material, adsorbents, cooking and processing of food were also studied. Thus, notwithstanding constraints on resources, Brazilian research responds to the needs of the country, reflects international concerns and recent developments in the area.

“…As noted by Sant'Ana, Rosenthal and Massauguer (2008), centrifugation, bentonite, filtration with diatomaceous earth and pectinase have been studied for their potential use in reducing PAT levels during apple juice production, but this least reduces the PAT levels by only 4.5%. Ross et al (1998) observed that patulin was metabolized by other microorganisms, such as yeast and bacteria that replaced filamentous fungi. Fuch et al (2008) also demonstrated the detoxification of mycotoxins by two lactic acid-producing bacteria; in this in vitro experiment, the bacteria reduced the concentration and toxicity of patulin and ochratoxin.…”

The rapid increase in the global production of apples has led to improved monitoring and control of toxic substances present in apples and their derivatives. One of these toxic substances is patulin, a mycotoxin and secondary metabolite produced by different fungi species of the genera Penicillium, Aspergillus, Gymnoascus, Paecilomyces and Byssochlamys. This study evaluated patulin levels in juice produced from Fuji apples subjected to different temperature conditions and storage times in southern Brazil. The apples were divided into groups weighing 1 kg and stored at the following temperatures: 0ºC, 5ºC, 6.7ºC, 19.5ºC and 25ºC. Sub-samples of each group were processed to determine their patulin level by HPLC at the following intervals: 0 (control group), 7, 14 and 21 days. After 28 days of storage at all temperatures, the apples could not be analyzed due to their deterioration. The results indicated that at all temperatures; there was variation in the patulin levels. The smallest patulin value was observed in apple juice stored at 19.5°C and 25°C
