Fresh-cut fruits are often more perishable and exhibit browning shortly after pulp is cut and exposed to natural atmosphere. In this study, fresh-cut peaches were treated with distilled water (control), 20 g L-1 soy protein isolate (SPI), 10 g L-1 calcium chloride (CaCl2) or 20 g L-1 soy protein isolate + 10 g L-1 calcium chloride (20 g L-1 SPI + 1.0 g L-1 CaCl2), respectively, and then stored at 0°C to assess the protective effects of these treatments on the qualities and the antioxidative system of fresh-cut peaches. The result showed that firmness, colour(∆E*) and soluble solid content (SSC) in fresh-cut peaches treated with 20 g L -1 SPI + 10 g L-1 CaCl2 were higher than control. Compared with other treatments, treatment with 20 g L-1 SPI + 10 g L-1 CaCl2 2 significantly decreased weight loss rate, bacterial growth, respiratory rate and ethylene emission of fresh-cut peaches. Treatment with 20 g L-1 SPI + 10 g L-1 CaCl2 also inhibited increase in browning degree, production of reactive oxygen species, malonaldehyde and total phenols, and maintained higher activities of superoxide dismutase and catalase, whereas inhibited the activities of peroxidase and polyphenol oxidase. These results suggest that treatment with 20 g L-1 SPI + 10 g L-1 CaCl2 enhanced antioxidant activities of fresh-cut peaches, inhibited browning, and was more effective in maintaining the quality of fresh cut peaches.

This study aimed to maximize the utilization of date palm residues and convert them into an environmentally friendly form of fuel. The residues of the date palm variety Khalas (leaf fronds and whole fronds) were used to produce fuel briquettes at three moisture contents (8, 10, and 12%) and four storage times (0, 15, 30, and 45 days). The mechanical, fuel, and quality properties of these briquettes were investigated. The results showed that the leaf fronds had the best results in terms of mechanical properties and fuel quality properties of the briquettes. The best results for compressive stresses for the leaf fronds were 24.98 MPa at 10% moisture content and for the whole fronds were 4.27 MPa at 12%. The second storage period gave the best results for all briquettes at the different moisture contents. The results showed significant effects of moisture content and storage period on mechanical properties. The hydrolysis time and durability of the briquettes increased with increasing moisture content. The calorific value of leaf fronds and whole fronds briquettes ranged between (17.78 and 18.12 MJ/kg) and (16.54 and 17.78 MJ/kg), respectively. These good quality briquettes can be handled and used, especially in rural areas where other energy sources are not available.

In this study, different rice flours (white, red, and black rice) were mixed with two banana (“Ambon” and “Nangka”) flours to formulate snacks for the elderly. This study aimed to obtain the characteristics and quality of the banana flakes made with different rice and banana flours and determine the best combination for the elderly. The following were assessed in this study: the chemical properties (moisture, ash, protein, fat, carbohydrate, TDF, total sugar, mineral, inulin, TAC, and antioxidant activity), physical properties (color, hardness, and fracturability) and sensory evaluations. The results of our study showed that banana flakes made from black rice flour and ’Nangka’ banana flour had the highest contents of potassium, magnesium, zinc, and antioxidant activity. Furthermore, the texture of this formulation showed less hardness and high fracturability. However, all formulations showed the same acceptability on sensory evaluations based on the overall parameters. Thus, although banana flakes made from black rice flour and ‘Nangka’ banana flour are highly recommended for the elderly because of their texture and nutrients, using other formulations is also edible and can be consumed for health benefits.

This study aims to evaluate the physico-chemical composition, techno-functional properties and in vitro antioxidant and antidiabetic activities of papaya, pineapple and mango peels for their possible use as functional ingredients. The peel powders were found to possess interesting techno-functional properties, high dietary fiber content (37.77 to 62.26%) and phenolic compounds, namely gallic, ferulic, and p-coumaric acid, catechin, quercetin-3-β-d-glucoside and quercetin. They also showed excellent antioxidant activity, as determined by ABTS (3.63 to 29.8 µM TE/g), DPPH (5.76 to 35.3 µM TE/g), NO (60.67 to 86.35%) and O (17.56 to 50.64%). Mango peel powders presented the best ability to inhibit the activity of the different enzymes evaluated: modest α-amylase inhibition (51.40%), stronger α-glucosidase inhibitory activities (70.32%), and moderate antiglycation potential (57.15%). Peel powders of these tropical fruits make them suitable to be used as food ingredients with possible health benefits, improving intestinal function and controlling hyperglycemia.

This study aimed to determine the effect of various environmental factors on the somatic cell count (SCC) in cow’s milk. The material of the study consisted of an SCC analysis result obtained from 207.614 raw milk samples collected from 65.288 head cattle had different breeds, ages, lactation number, and lactation length between May and December in 2019. They were raised on 6,305 dairy farms that are members of the Cattle Breeders Association (CBAT). In order to determine the effect of region, city, and cattle breed on SCC in raw milk of cattle, a regression tree was created using the Chi-square Automatic Interaction Detection (CHAID) algorithm, a Data Mining (DM) method. Accordingly, the mean SCC value of all enterprises was determined as 201.253 cells/mL. In this study, it was found that the region, city and breed groups with the highest average somatic cell counts were CAR, MSR, MR and SAR region group (285.430 cells/mL); C09, C45, C20, C64, C48, C43 city group (266.744 cells/mL); and HF, MC, and BS breed group (295.705 cells/mL). As a result of this study, the variables affecting SCC were determined as region, city, and breed respectively, in order of importance. Keywords: CHAID; Dairy cattle; Somatic cell count

It is still not clear whether differential response of Bt cotton and conventional non-Bt cotton genotypes in terms of growth, phenology and yield ability are hypothetical or realistic. This study investigated the response of three Bt cotton hybrids in comparison to their conventional non-transgenic version (near-isogenic lines) along with two locally adapted genotypes for growth, yield attributes, phenological characteristics and rooting behavior. Therefore, two experiments were conducted during summer season of year 2016 and 2017 to evaluate differences among 3 popular Bt cotton hybrids along with their non-Bt version. First field experiment was conducted as a pot study wherein shoot and root parameters of 3 Bt cotton hybrids (Ankur 3028, MRC 7017, Bioseed 6588) were compared with their non-Bt version along with 2 local checks (i.e.,hirsutum cotton Cv. F2228 and arboreum cottonCv. FDK124). Second field experiment evaluated growth, phenological characteristics, yield attributes and productivity potential of above mentioned Bt and non-Bt hybrids. Findings of pot experiment could not establish any significant difference among studied Bt and non-Bt hybrids for root and shoot characteristics. However, arboreum cotton FDK124 exhibited higher root length than all genotypes. Results of second experiment revealed significant differences for phenological characteristics, wherein Bt version of all the tested hybrids exhibited earliness for flowering initiation, 50 % flowering and days to maturity over their non-Bt version. Seed cotton yield (SCY) in all hybrids possessing Bt gene was significantly higher than their non-Bt version primarily due to higher bolls plant-1. Studies conclude that introgression of Bt gene could not alter rooting parameters of evaluated cotton genotypes but significantly affected phenological stages by inducing earliness and higher SCY in Bt versions due to improved bolls plant-1.

The aim of this study was to investigate the effect of different age and plumage color on the egg quality traits and cholesterol levels, in addition to which traits can be used for egg weight prediction in Japanese quails. The eggs obtained from 23-week-old original plumage colored Japanese and Jumbo quails, and 39-week-old Jumbo quails; 40, 40, and 20 eggs were used respectively as the research material. The eggs obtained from 23-week-old original plumage colored Japanese and Jumbo quails, and 39-week-old Jumbo quails; 40, 40, and 20 eggs were used respectively as the research material. In terms of plumage color difference, when Japanese quails were compared to Jumbo quails; yolk weight, yolk height, yolk diameter were higher, and likewise the cholesterol level was lower (P<0.01). The lowest cholesterol content was found in eggs from 23-week-old Japanese quail (P<0.01). Egg width, shape index, yolk height, and shell weight in group 1; albumen weight, yolk diameter, and egg volume in group 2; egg volume and egg length data in group 3 have determined the best fit for estimation of the egg weight. As a result, the plumage color is a factor that affected the egg quality traits and cholesterol level in quails. Furthermore, some egg quality traits may be used to establish the equations for estimation of the egg weight. Keywords: Age; Egg quality traits; Egg weight estimation; Plumage color; Quail

Salinity is assumed to be a distressing abiotic factor that mainly disrupts crop quality and yield by impairing plant cell mechanisms. Due to ion accumulation, salinity stress results in lowering growth rate and water uptake. This issue is being solved by the use of several plant growth regulators. Plant growth regulators have been proven to increase plants' ability to withstand against stress. In this study, turnip (purple top cultivar) was subjected to four distinct levels of salt (0, 4, 8, and 12 dS/m), as well as one level of gibberellic acid, in order to assess the function of exogenously applied plant growth regulator glutamic acid (GA) (10 mM). Results revealed that salt stress slowed plant growth and decreased the amount of chlorophyll in turnip leaves. Application of salt alone resulted in a considerable decline in biochemical characteristics. However, in salt-stressed conditions, exogenous application of GA improved the antioxidant activity, chlorophyll contents and plant growth in the turnip leaves. Moreover, results depict that under salt stress vitamin C decreased; however, exogenous application of GA enhanced the Vit. C in turnip plants.

Due to ion accumulation, salinity stress results in lowering growth rate and water uptake. This issue is being solved by the use of several plant growth regulators. Plant growth regulators have been proven to increase plants' ability to withstand against stress. In this study, turnip (purple top cultivar) was subjected to four distinct levels of salt (0, 4, 8, and 12 dS/m), as well as one level of gibberellic acid, in order to assess the function of exogenously applied plant growth regulator glutamic acid (GA) (10 mM). Results revealed that salt stress slowed plant growth and decreased the amount of chlorophyll in turnip leaves. Application of salt alone resulted in a considerable decline in biochemical characteristics. However, in salt-stressed conditions, exogenous application of GA improved the antioxidant activity, chlorophyll contents and plant growth in the turnip leaves. Moreover, results depict that under salt stress vitamin C decreased; however, exogenous application of GA enhanced the Vit. C in turnip plants. Further, the uptake of salt content in turnip roots and leaves was significantly lowered by the application of GA. Additionally, under salt stress; GA dramatically controlled the quantity of phenolic compounds in turnip. \u0000Keywords: Brassica rapa, Salinity, Glutamic acid, Morphological and biochemical assay, Reducing and non-reducing sugar","PeriodicalId":11648,"journal":{"name":"Emirates Journal of Food and Agriculture","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49608459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Local farmers combine several methods to manage soil organic matter: improve the quality and integrate other processes of managing the fertility of cultivated soils. The purpose of this work is to evaluate the effects of different organic amendments (OA) on any physico-chemical properties of the soil such as: pH, electrical conductivity (EC) and organic matter (OM). The amendments are: palm compost and manure (CPM); palm compost and reed (CPR); palm compost and reed + manure (CPRM); ovine manure (Om) and unamended soil (Ctl). The choice of materials is based on the idea of valorizing palm groves waste (palms and reeds) with ovine manure. The trial is conducted on randomized complete block design where two levels of soil samples are taken two months apart: S0 (day zero), Sin (initial sampling before application of amendment) then, S1, S2 and S3 until the end of cropping cycle. Obtained results show that all different OA increase the pH and decrease the EC of the soil after two months of application (S1) compared to the value of the initial sampling (Sin), which demonstrates the very highly significant effect of time on both parameters in the surface horizon. For the OM an incessant increase during the assay period was noticed where Om and CPR have marked the highest values during the third sampling (S3). This proved that the prepared composts from oasian wastes have an effect in improving soil properties over time. From an economic point of view, CPR showed results of OM that are similar of Om, which is considered as the most used and expensive manure in the region.

In the oasis agro-system, salinization and hydromorphy are the principal degradation factors that negatively affect the soils. These two processes are the result of the rise of the water table caused by the overdose of irrigations. To counteract soil degradation and restore field productivity, the oasis farmers turn to use sandy and manure amendments. Therefore, three treatments (Control (C), sandy amendment (T1) and combined amendments composed by sand and manure (T2)) has been applied in Nefzaoua oasis to evaluate the effect of different amendments on oasis soil fertility, irrigation parameters, and barley yield. Results showed that T2 enhanced yield parameter (3,07 t/ha) compared to control treatment (1.85 t / ha) thanks to the improvement in the total nitrogen concentration (1.38 g kg -1), soil organic carbon (28.74 g kg- 1) and therefore C / N ratio (20.78) for T2 treatment at the level of the 0-20 cm layer. The results revealed that sand + manure combination (T2) enhanced the irrigation dose that can be effectively applied for the barley plants (19.61 mm) compared to the control treatment (15.49 mm) and T1 treatment (12.26 mm). In addition, the combined treatment T2 declined significantly the oasis soil bulk density leading to rise the porosity of the top layers (0-20 cm). Our results obtained confirmed the effectiveness of the combined amendment composed of sand and manure in improving the fertility and productivity of the amended oasis soil.
