The effects of nitrogen fertilization (NF, 60-100 kg ha-1) and parboiling operation (soaking temperature (SoT, 50-80°C) and steaming time (StT, 10-15 min)) on the protein content (PC), amylose content (AC), gelatinization temperature (GT), hardness value (HV), peak viscosity (PV), trough viscosity (TV), final viscosity (FV), breakdown (BD), setback (SB) point, peak time (PTi), and pasting temperature (PTe) of brown rice were evaluated. Results showed that the GT, HV, FV, and TV were significantly increased by increasing the NF, SoT, and StT levels. An increase in the SoT and StT levels led to a significant reduction in PC, AC, BD, and TV values. The AC (17.13-16.83%) and PV (1605-1588 cP) values were decreased by increasing the NF level, while the PC (8.78-9.46%) and BD (226.9-247.7 cP) values were increased. Rheological parameters of BD (336.4 cP), FV (3608.5 cP), and SB (1843.5 cP) were notably increased using the combined treatment of 100 kg ha-1 NF and of 80°C SoT. The best triple treatments for the improved GT (5.0 °C), HV (19.37 N), as well as FV (3923 cP), and SB (1949 cP) were 60 kg ha-1 NF+80°C SoT+15 min StT, 100 kg ha-1 NF+80°C SoT+15 min StT, and 100 kg ha-1 NF+80°C SoT+10 min StT, respectively.
氮肥（NF，60-100kg ha-1）和蒸煮操作（浸泡温度（SoT，50-80°C）和蒸制时间（StT，10-15min））对蛋白质含量（PC）、直链淀粉含量（AC）、糊化温度（GT）、硬度值（HV）、峰值粘度（PV）、谷粘度（TV）、最终粘度（FV），并对糙米的糊化温度（PTe）进行了评价。结果显示，通过增加NF、SoT和StT水平，GT、HV、FV和TV显著增加。SoT和StT水平的增加导致PC、AC、BD和TV值的显著降低。AC（17.13-16.83%）和PV（1605-1588 cP）值随着NF水平的升高而降低，而PC（8.78-9.46%）和BD（226.9-247.7 cP）则升高。使用100 kg ha-1 NF和80°C SoT的联合处理，BD（336.4 cP）、FV（3608.5 cP）和SB（1843.5 cP）的流变参数显著增加。改善GT（5.0°C）、HV（19.37N）以及FV（3923cP）和SB（1949 cP）的最佳三重处理分别为60 kg ha-1 NF+80°C SoT+15min StT、100 kg ha-1 NF-+80°CSoT+15minStT和100 kg ha-1NF+80℃SoT+10min StT。

Pollen analysis is the basic method for the determination of the botanical and geographical origin of honey. However, the presence of over-represented pollen in honeys may lead to false results of the analysis. This can be more severe if this pollen is present in unifloral under-represented honeys of commercial importance (e.g. thyme or acacia honey). In the present study, we investigated the abundance of nectarless pollen grains on several quality characteristics in honey samples. In particular, the physic-chemical (diastase activity, electrical conductivity, sugars and HMF content) analysis were carried out in order to confirm the declared botanical origin. Spectrophotometric method was used for diastase activity determination, electrical conductivity was determined by potentiometry and chromatographic determinations for HMF content (photodiode array detection) and sugars (HPLC refractive index detection). The present study confirms that, in the case of non-nectariferous pollen presence in honeys, a second count must be made, excluding this pollen type and pollen analysis alone cannot give reliable results for the determination of the botanical origin. Consequently, pollen analysis should be combined with other analyses, especially in honeys with under-represented pollens, to give precise results for the botanical characterization and labeling of honeys.

Faba bean is an important grain legume, grown for human consumption and animal feed and can be used as an alternative to soybean protein. Drought and heat strongly influence faba bean growth and production, especially in flowering and pod development stages. The aim of this study was to determine the response of six cultivars to different environmental conditions during the 2018-2019 growing season. Four inbred lines and two commercial cultivars were sown in different environments in South, Central and North Greece. At each location, a randomized complete block design with four replications was used. Different characteristics such as plant height, number of pods plant-1, number of seeds pod-1, seed yield and 1000-seed weight, were recorded. The results indicated that all traits were significantly affected by different climatic conditions and cultivars. In most cases, seed yield and 1000-seed weight decreased with increasing drought conditions in the southern site. KK10 produced higher yield and pods plant-1, especially in North and Central Greece. The late maturity cultivars, ‘Polycarpe’ and KK14, showed lower values for the seed traits under all locations. Multi-location trials are useful for the evaluation of new cultivars and lead to an increase in production of feedstuff directly available to farmers.

Flavoured honey is an increasingly popular product among consumers. Enriching honey with other healthy ingredients such as spices, herbs, dried fruits, pollen and propolis is a way to create new innovative products, with benefits for both, beekeepers and consumers. The purpose of the study was to test four types of flavoured honey among young consumers segment in Slovakia: honey with cacao, honey with cinnamon, honey with turmeric and honey with pollen, by using an interdisciplinary approach. The research combined sensory analysis, consumer research and laboratory tests methods aiming to find the consumer interest and acceptability of these products. Based on overall sensory analysis, honey with cacao and cinnamon obtained the best evaluations in terms of aroma, taste and colour, while honey with turmeric obtained the worst. Laboratory tests showed that all four types of flavoured honey have higher antioxidant activity than normal pure honey. Communicating these results to consumers partially influenced their preferences. The results of consumer research indicate that flavoured honey was perceived as innovative and natural product and the majority of respondents would buy it.

Currently, in Romania there are just a few autochthonous white kidney bean varieties and this is the main reason why Vegetable Research Development Station (VRDS) Buzau has chosen a breeding program for this species. The aim of this study was to assess the main quantitative characteristic of a new cultivar of kidney beans, ‘Doina’. The correlation matrix showed a strong relationship between plant height and bush diameter and also with leaf length and a negative correlation between plant height and pods mass per plant. The cultivar has a yield potential of over 3000 kg/ha and a compact maturation of the pods, being suitable for mechanized harvesting. An important feature is plant hardiness, due to local genetic resources used in the breeding program. During the research it was found that the variety has a distinct phenotypic expressiveness with a high yield and quality potential.

Following the periodic evaluations carried out in the parks of Timisoara (Timis, Romania) which had as main activity the monitoring of harmful insect species, we noticed an interesting species with the ability to jump, which attracted our attention. It has been identified as Scudderia sp. This was not found so far in the western part of Romania or in other areas of the country (to our knowledge). So we started to study it in more detail, to monitor it and to see if there are injuries on ornamental plants. The observations were made during 2019 and 2020, in five representative parks in Timisoara. The insect was reported in two parks. Both immature forms (larvae and nymphs) and adult forms were present, starting with June. The last specimens were observed at the end of September. The population level found in the parks of Timisoara is quite high and the aesthetic damage caused to ornamental plants is clear. The plants that katydids were seen feeding on, were diverse. The most affected of these (about of 30-60%) were those of rain flower, African daisy flowers and roses.

The objective of this study was to investigate the possibility of cholesterol elimination from milk using betacyclodextrin at pilot station scale, because there is very little information considering this level of milk processing. β-cyclodextrin is a nontoxic, edible and chemically stable compound with affinity for nonpolar molecules like cholesterol, giving the opportunity for obtaining food products that can prevent the appearance of cardiovascular diseases. By applying of this procedure, the cholesterol reduction percentage was calculated as approximately 84 %, similar to the values reported by the specialty literature. Except fat and freezing point values, the other parameters values increased with an approximate percentage of 8, indicating a concentration phenomenon due to milk pasteurization. Fat concentration value decreased with 5.9 %, due to the cholesterol inclusion in the betacyclodextrin molecule and its elimination at the bottom of the centrifugal separator. However the variation of the parameters is insignificant, so this process could be considered efficient to be applied at a pilot station level.

The presence of trace, heavy metals in foodstuffs is of intense public interest. The aim of this study was to determine the metal contents in most known commercial fruit juices present on the Romanian market. The multielement analysis was made using the ICP-MS technique, after appropriate dilution, using the external standard calibration method. Multifruit, mango, and kiwi juice have recoded the highest concentration of Cu, while apple and pear juice has recoded the lowest concentration, and in the case of Zn, peach juice has recoded the highest concentration. Concerning Pb, Cd, and As concentration, apple, peach, and multifruit juices recorded the highest levels of concentration. The concentration of Zn, Cu, Co, and As generally, was higher in the juice samples packed in boxes, while Ni, Cr, Pb, and Cd recorded the highest values in the juice packed in plastic bottles.

The existence of antimicrobial residues in food of animal origin is a safety concern worldwide. This study investigated the occurrence of such residues in table eggs collected from Erbil city (Iraq) markets according to shell color, location, and season. Results showed that the total proportion was 15.2%. The differences were not significant for the shell color (White color 13.7%; Brown color 16.8%), location (Urban 16.4%; Rural 13.8%), and months (July 12.1%, August 13.5%, September 18.8%, October 15.7%, December 16.9%, and November 14.1%). Such level of residue contamination requires a response from in-charge Iraqi health authorities to regulate antibiotics usage and ensure food safety.
