While the medical community supports the growth of citrus consumption as part of a healthy diet, there is limited knowledge about consumer preferences for these fruits. The current study analyzed the purchasing patterns and drivers of fresh citrus fruits from a convenience sample of 346 Italian food shoppers. Results revealed that clementines were the citrus fruit purchased most, followed by oranges and tangerines. Sweetness and smell were important product attributes for respondents. Different drivers affect the purchasing frequencies of various citrus fruits. Taste motivation, with a specific preference for acidity, impacts orange purchasing. Similarly, clementines are purchased primarily for taste motivation, however, the core sensory attribute for respondents in this case was sweetness. Meanwhile, for tangerines, the taste motivation is less important than the energy motivation, and the size together with the color are the core purchasing drivers. These outcomes provide food scientists, agronomists and market practitioners with new insights into Italian consumers’ preferences for citrus fruits, thus contributing to a potential expansion of this market.

AbstractEfficient methods to achieve the safe decontamination of agricultural products are needed. Here, we investigated the decontamination of citrus fruits to test the antifungal potential of a novel non-thermal gas plasma apparatus, termed a roller conveyer plasma instrument. This instrument generates an atmospheric pressure dielectric barrier discharge (APDBP) plasma on a set of rollers. Penicillium venetum was spotted onto the surface of the fruit or pericarps, as well as an aluminium plate to act as a control, before performing the plasma treatment. The results showed that viable cell number of P. venetum decreased with a decimal reduction time (D value or estimated treatment time required to reduce viable cell number by 90%) of 0.967 min on the aluminium plate, 2.90 min and 1.88 min on the pericarps of ‘Kiyomi’ (Citrus unshiu × C. sinensis) and ‘Kawano-natsudaidai’ (C. natsudaidai) respectively, and 2.42 min on the surface of ‘Unshu-mikan’ (C. unshiu). These findings confirmed a fungicidal effect of the plasma not only on an abiotic surface (aluminium plate) but also on a biotic surface (citrus fruit). Further development of the instrument by combining sorting systems with the plasma device promises an efficient means of disinfecting citrus fruits during food processing.

Organic agriculture, based on natural production technologies, obtains a great potential for reversing humanity to a healthy diet and living in harmony with nature by improving the state of the ecosystem. The share of organic food products in the market of the developed countries is already quite high; and various institutional systems of the industry have been introduced and are being improved in the leading countries of the world. Domestic agribusiness is currently lagging behind in these matters, but the situation should be significantly changed by the adopted law and state standard regulating the requirements for the organic sector. In this regard, an objective need arose to substantiate the capabilities and the resource potential of the Saratov region in this sphere. Within the framework of the presented research, an interdisciplinary fundamental platform to develop the theory of the organic food products market was formed. As a result, the elements of the scientific methodology (theories, principles, factors, methods) of its functioning were identified, which made it possible to substantiate the potential capacity of the regional consumer market for organic food. The calculation was made taking into account the rational norms of food consumption that meet modern requirements for a healthy diet, the heterogeneity of consumer preferences, the price gap for the main conventional and organic products in retail and the dispersion of prices for the latter, the implementation of state policy to protect and improve the health of certain population groups. This study is intended for the state management bodies of the agro-industrial sector, the leadership of agricultural, processing and marketing enterprises, the structures of wholesale and retail food products trade and branch research institutions.

A new computer vision algorithm for citrus fruit quality classification based on the size of a single tree fruits was developed in this study. The image properties of area, perimeter, and diameter for the citrus fruits were measured by pixels. In order to estimate citrus fruit size in a realistic manner, the ratios of diameter, perimeter and area in pixel values in relation to the actual size of one fruit were determined. The total of 1860 citrus fruits were grouped based on diameter, perimeter, and area in pixels. The results of the grouping of citrus fruits by diameter, perimeter and area were compared with the results of the survey research into citrus fruit size as conducted by the Jeju Citrus Commission. Comparative results reveal that the image of the citrus fruit diameter in pixels demonstrate a more accurate size than the other two pixel values, i.e. perimeter and area.

Among the many approaches to COVID-19 prevention, the possible role of diet has so far been somewhat marginal. Nutrition is very rich in substances with a potential beneficial effect on health and some of these could have an antiviral action or in any case be important in modulating the immune system and in defending cells from the oxidative stress associated with infection. This short review draws the attention on some components of Citrus fruits and especially of the orange (Citrus sinensis), well known for its vitamin content, but less for the function of its flavonoids. Among the latter, hesperidin has recently attracted the attention of researchers, because it binds to the key proteins of the SARS-CoV-2 virus. Several computational methods, independently applied by different researchers, showed that hesperidin has a low binding energy both with the coronavirus "spike" protein, and with the main protease that transforms the early proteins of the virus (pp1a and ppa1b) into the complex responsible for viral replication. The affinity of hesperidin for these proteins is comparable if not superior to that of common chemical antivirals. The preventive efficacy of vitamin C, at dosage attainable by diet, against viral infections is controversial, but recent reviews suggest that this substance may be useful in case of increased stress on the immune system. Finally, the reasons that suggest undertaking appropriate research on the Citrus fruits addition in the diet, as a complementary prevention and treatment of COVID-19, are discussed.

Citrus Bergamia

Bergamot is a characteristic citrus fruit of the province of Reggio Calabria (South Italy) and until today it was mainly known for the production of its peel essential oil. Since some year, due to the positive feedback from consumers, there has been a growing interest in the bergamot juice which in the past was not used as a beverage because it was considered very sour. The recent studies on the functional aspects of citrus fruits and therefore also on bergamot have made this fruit known to a new youth. They exist three cultivars: Castagnaro, Fantastico and Femminello. In this study the biometrics of the fruits and the physico-chemical characteristics of the juice have been taken into consideration, such as: Brix degrees, pH, pulp content in the squeezed juice, turbidity, acidity, vitamin C, Formol number, single and total flavonoids. Total flavonoids in the bergamot juice ranged between 362 and 520 mg/L whereas in the Cloudy juice they ranged between 4660 and 8468 mg/L. The composition in fatty acids and in sterols of the seed oil of this fruit was also analysed to evaluate its potential. Oleic acid (30.15-34.36%) and linoleic acid (27.01-29.84%) were found in similar quantity, while the most present sterol was β-sitosterol (76.9-79.2%).

Among the many approaches to Coronavirus disease 2019 (COVID-19) prevention, the possible role of nutrition has so far been rather underestimated. Foods are very rich in substances, with a potential beneficial effect on health, and some of these could have an antiviral action or be important in modulating the immune system and in defending cells from the oxidative stress associated with infection. This short review draws the attention on some components of citrus fruits, and especially of the orange (Citrus sinensis), well known for its vitamin and flavonoid content. Among the flavonoids, hesperidin has recently attracted the attention of researchers, because it binds to the key proteins of the Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Several computational methods, independently applied by different researchers, showed that hesperidin has a low binding energy, both with the coronavirus “spike” protein, and with the main protease that transforms the early proteins of the virus (pp1a and ppa1b) into the complex responsible for viral replication. The binding energy of hesperidin to these important components is lower than that of lopinavir, ritonavir, and indinavir, suggesting that it could perform an effective antiviral action. Furthermore, both hesperidin and ascorbic acid counteract the cell damaging effects of the oxygen free radicals triggered by virus infection and inflammation. There is discussion about the preventive efficacy of vitamin C, at the dose achievable by the diet, but recent reviews suggest that this substance can be useful in the case of strong immune system burden caused by viral disease. Computational methods and laboratory studies support the need to undertake apposite preclinical, epidemiological, and experimental studies on the potential benefits of citrus fruit components for the prevention of infectious diseases, including COVID-19.

ObjectiveA healthy diet is associated with reduced risk for stroke, myocardial infarction, cancer and death. We examined the prevalence of a healthy diet in patients with a recent stroke or transient ischaemic attack (TIA).MethodsWe recruited a convenience sample of 95 patients with a recent ischaemic stroke or TIA. Using information from a 125-item Food Frequency Questionnaire, we calculated dietary quality and the percentage of patients meeting recommended daily intake (RDI) for common macronutrients and elements.ResultsThe mean age of patients was 66 years (SD: 16) and 46% were women. 39 patients (41%) were classified as having a healthy diet (35% of men and 48% of women). The majority of patients were within the RDI for carbohydrates (56.8%), total fat (61.1%), long-chain n-3 fats (68.4%), polyunsaturated fats (79.0%) and protein (96.8%). Very few patients consumed the recommended intake for sodium (25.3%), and even fewer consumed the RDI for potassium (4.2%), with the majority of patients consuming too much sodium and too little potassium.ConclusionWe found that most patients with recent stroke or TIA were not following a healthy diet before their stroke event. For most patients, sodium intake was much above and potassium intake was much below RDI.

Morpholine salts of fatty acids have been used in wax coatings on the surfaces of fruit and vegetable commodities in China and the United States, etc. However, morpholine usage was prohibited in many other countries because of safety concerns. We optimized analytical methods to determine morpholine in the peel and pulp of fruits and vegetables by gas chromatography-mass spectrometry (GC-MS). This morpholine analysis method was applied to real samples of apples, citrus fruits, and vegetables from Korea, China, and the U.S. The method was validated using apple and citrus fruit peels and pulp. The method detection limit (MDL) was 1.3–3.3 µg/kg. The recovery rates of morpholine were 88.6–107.2% over a fortified level of 10–400 µg/kg. Intra-day and inter-day precisions were 1.4–9.4% and 1.5–2.8%, respectively. The morpholine concentrations were n.d. (not detected)–11.19 and n.d. (not detected)–12.82 µg/kg in apple and citrus peels, respectively. Morpholine was not detected in citrus or apple pulp samples or in vegetable samples.

Abstract A method has been developed for the cleanup and screening of extracts from citrus fruit for residues of benzo(a)pyrene, 3-methylcholanthrene, and dibenz(a,h) anthracene. Whole fruits were stripped with pentane, the pentane solution was partitioned with dimethyl sulfoxide, the extract was adsorbed on a magnesia column, and the residue from the eluate was chromatographed on thin layer plates beside spots of standard polynuclear hydrocarbons. The addition of 4.1 μg of either benzo(a)-pyrene or 3-methylcholanthrene to the surface of individual fruits was detected, after cleanup, in extracts stripped from samples of 10–15 oranges or 15–20 lemons. Dibenz-(a,h) anthracene added at levels of 0.1 fig per fruit was detected in only occasional samples. With this procedure, no residues of benzo(a)pyrene, 3-methylcholanthrene, or dibenz(a,h) anthracene were detected in more than 40 paired samples of nonwaxed and commercially waxed citrus fruits. With the proposed cleanup procedures, recoveries of the polynuclear hydrocarbons ranged from 50 to 80% as determined by ultraviolet spectral analysis.
