This paper aims to assess the potential of date fruit powder as a refined sugar replacer in rock buns to help promote and diversify the utilization of date fruit.

Date fruit pulp was sun dried, milled into powder, sieved and its proximate composition determined. Refined sugar in rock buns was replaced with date fruit powder at 0, 50, 80 and 100 per cent levels. The samples were then subjected to proximate, mineral and sensory evaluation.

Date fruit powder had 1.47 per cent crude fiber and was high in carbohydrate (82.15 per cent). Carbohydrate content of samples decreased (48.55-29.72 per cent), while crude protein (6.78-9.97 per cent), crude fat (22.74-33.66 per cent) and crude fiber (0-0.49 per cent) contents increased with an increasing substitution of date powder. Of all, 0 and 50 per cent substituted rock bun samples were the most preferred. Date powder significantly (p < 0.05) increased the potassium (0.55-1.57 per cent), calcium (0.08-1.08 per cent) and iron (0.53-0.625 per cent) contents of the samples.

This research assessed the potential of date fruit powder as a replacer of refined sugar in rock buns, as it remains an underutilized commodity in Ghana. Replacing 50 per cent of refined sugar improved the nutrient composition of rock buns, thereby making date fruit powder a nutritious sugar replacer which could be used in pastry products. This when adopted would diversify the utilization of date fruits while providing good nutrition to consumers.

The purposes of this study were to analyze fruits, vegetables, water and soil for organochlorine pesticide (OCP) residues and to assess the food exposure of these pesticides in Qatar.

Pesticides were quantified in dates, leafy vegetables, fruiting vegetables, water and soil samples using a gas chromatography-electron capture detector and gas chromatography-mass spectrometry. These pesticides were α-benzene hexachloride (BHC), ß-BHC, heptachlor, aldrin, g-chlordane, endosulfan I, α-chlordane, dieldrin, endrin and methoxychlor. Additionally, food exposure risk assessment was performed by estimating daily intakes of OCP.

Most analyzed samples contained at least one OCP residue. Endosulfan was the only pesticide that was not detected. The concentrations of OCP in samples were below the maximum residue level (MRL) except endosulfan. Among all the samples analyzed, ˜18% of those exceeded the MRL with respect to the concentrations of methoxychlor and heptachlor. Only intake of methoxychlor (0.018 mg/day) exceeded the MRL (0.01 mg/day). Dates and fruiting vegetables were likely to pose a higher risk than leafy vegetables because they contained heptachlor, endrin and methoxychlor. Leafy vegetables might pose a greater risk than dates and fruiting vegetables because of the presence of β-BHC and dieldrin.

Eight out of ten OCPs that were measured were found to be below the MRL. These pesticides should be eliminated from the food supply based on the Qatar National Implementation Plan of the Stockholm Convention in 2010. Based on the intake risk assessment, overall, the intake of OCP may not pose a major risk to human health as the concentrations of OCP were below MRL, except methoxychlor. Water and soil are the potential sources of contamination of OCP in foods that were tested in Qatar. To limit the health risks associated with OCPs, there is a need for close monitoring of food and agricultural practices and the types of pesticides imported into Qatar.

This paper investigates how the channel leadership strategies develop a post-coronavirus disease (COVID-19) resilient agri-supply chain, which reduces supplier and retailer's price loss and enhances the logistics service quality level considering logistics outsourcing of agri-product especially for the rapidly changing market condition.

Based on the classical leadership theory, two channel leadership strategies, i.e. LPL and SL, are considered. The proposed framework first derives the equilibrium price and service quality level decision among the supplier, the logistics provider and the retailer. Then it compares both leadership strategies in terms of the equilibrium prices and service quality theoretically. This article also presents a case study of Arabian dates pricing and supply chain to test the theoretically derived propositions.

Selection of suitable leadership strategy is a critical factor for profit maximization of the supply chain drivers and proper optimization of equilibrium price and service quality. Here, the product's quality and the market's socio-economic condition play an important role in selecting a suitable leadership strategy. A random transformation of the physical market to an e-commerce portal creates a wide variation of the market's socio-economic parameters, affecting the equilibrium pricing and the logistics provider's service quality.

This study proposes a post-COVID-19 resilient agri-supply chain framework considering price and quality-dependent stochastic market demand, incorporating a wide range of socio-economic factors in the model to counteract the effect of rapid behavior change of agri-market due to COVID-19 norms. This research examines the effect of different channel leadership strategies to facilitate suitable decisions on prices and service quality and retrieve the profit of the supplier, retailer and logistics provider. The future models can incorporate competitiveness in logistics outsourcing, fourth-party logistics (4PL) and contract farming in the agri-supply chain. Each of the extensions can open avenues in different directions.

As the post-COVID-19 market and the customer behavior is randomly changing, and the traditional market is rapidly converting into supermarkets and e-commerce portals, this paper examines the model with a wide variety of e-commerce portals with multi-variation of product. It is conclusive that the product's quality and the market's socio-economic behavior significantly impact the equilibrium decision. The drivers of the supply chain must take them into account before choosing a particular channel leadership strategy.

This study considers a multi-product and multi-market (e-commerce) model by integrating a wide variety of products and the market's socio-economic parameters. The model is tested in a price and quality-dependent stochastic market condition, contributing to the literature by reconciling two different channel leadership strategies into the global logistics of fresh agri-product.

The purpose of this study was to investigate the sensory properties and chemical composition of corn and sorghum flakes manufactured using 25, 50, 75 and 100 per cent date syrup (DS), instead of sugar.

Ten individuals assessed the overall acceptability, taste, texture and aroma of flakes. The chemical composition of each type of flake was determined, and these characteristics compared with those of control corn and sorghum flakes (without DS).

The overall acceptability of sorghum flakes ranged from 6.3 (100 per cent DS flakes) to 6.8 (25 per cent DS flakes); however, the difference was not significant. Values for taste, texture and aroma of sorghum flakes ranged from 5.3 (taste of 100 per cent DS flakes) to 7.2 (texture of 25 per cent DS flakes). For corn flakes, values ranged from 6.20 (aroma of 100 per cent DS flakes) to 7.20 (texture of 25 per cent DS flakes). For both sorghum and corn, the colors of 25-100 per cent DS flakes were significantly different from controls (p = 0.0002). The total carbohydrate, fat, protein and ash contents were 81.669 per cent, 1.545 per cent, 13.27 per cent and 3.52 per cent for corn flour, and 83.38-85.78 per cent, 1.7-2.0 per cent, 10.02-12.13 per cent and 2.36-3.92 per cent for sorghum flour, respectively. The total carbohydrate, fat, protein and ash contents were 81.63 per cent, 5.75 per cent, 9.80 per cent and 2.82 per cent for corn, and 86.31-84.99 per cent, 3.15-4.27 per cent, 7.64-7.94 per cent and 2.92-2.79 per cent for sorghum flakes, respectively.

Corn and sorghum flakes produced with DS are acceptable to consumers, and their nutrient values indicate potential health benefits.

The purpose of the paper was to investigate the use of aqueous extract of date palm (Phoenix dactylifera) leaf as a green inhibitor for corrosion of carbon steel in 1M hydrochloric acid (HCl) solution.

Extracts from the date palm were used as the main component of an environmentally friendly corrosion inhibitor for use in HCl pickling processes. Inhibition behavior on carbon steel in HCl was investigated using weight loss measurements, linear and potentiodynamic polarization curves, electrochemical impedance spectroscopy and scanning electron microscopy.

The results show that the extract exhibited good inhibition performance in 1M HCl. The inhibition efficiency increased with increase in the concentration of the inhibitor but decreased with increase in temperature. Inhibition efficiency also was found to increase as immersion time increased. The inhibitive action was due to adsorption of the date palm leaf components on the steel, which was consistent with the Langmuir isotherm.

Date palm leaf extract (DPLE) is an effective inhibitor at room temperature and can be used to protect plain carbon steel from corrosion in HCl solution.

This study provides new information on the inhibiting characteristics of DPLE under specified conditions. The environmentally friendly inhibitor could find possible applications in metal surface anodizing and acid pickling processes.

The purpose of this paper is to describe reliability and relative validity of the short-food frequency questionnaire (SH-FFQ) used for assessing food groups and nutrient intakes of Iranian adults.

The food list used in the SH-FFQ was elaborated based on a dietary survey of a sample of 60 individuals aged between 15 and 65 years. A total of 180 subjects (93 males and 87 females) were included in the study. All participants completed two SH-FFQs with one month interval, a single 24 hours recall (24hR) and two food records for three non-consecutive days.

No significant differences were observed in the mean daily intakes of energy, food groups and most of the nutrients between the reference tools and the two semi-quantitative SH-FFQs (p>0.05). The mean energy-adjusted reliability coefficients for all variables were 0.54 and 0.55 in men and women. The mean energy-adjusted and deattenuated correlation coefficients for all items between the SH-FFQ and reference tools were 0.54. Also, the mean percent misclassified into opposite quartiles for all food groups and nutrients was 12.6 percent.

The designed SH-FFQ developed for the Life style Promotion Project has reasonable reliability and relative validity for food groups and nutrient in Iranian adults.

The purpose of this article is to investigate on changes of the microbial load and the chemical and physical properties of date fruits stored for 6 months under two different temperatures.

A composite sample of 100 kg date fruits from the Khalas variety, season 2019, was collected from the local market in Al Ahsa Province, Saudi Arabia, packaged in 1 kg lots, stored at room and refrigerator temperatures and the microbial contamination and the chemical and physical properties monitored over a period of six months of storage. Total bacteria, lactic acid bacteria, Enterobacteriaceae, yeasts and molds were counted and representatives of yeast and mold contaminants were identified using morphological, physiological and molecular typing techniques. Changes in the color and texture of the samples were also monitored during storage.

The yeasts detected were two strains of each of Lachancea thermotolerans and Rhodosporidiobolus fluvialis and one strain of Cystofilobasidium lacus-mascardii. For molds, one strain of each of Aspergillus niger, Aspergillus flavus, Penicillium chrysogenum and Aspergillus caespitosus have been detected. No significant growth of these microorganisms was observed, but enough load persisted during storage that makes the samples not meeting the microbiological standards. There were significant changes in the color and texture of the fruits during storage.

These findings add important information that can help producers and processors to improve quality and promote marketing of date fruits, especially to international markets.

The purpose of this paper is to describe recent fruit picking robot developments with an emphasis on corporate activity rather than academic research. It also aims to provide a view on the commercial prospects for these developments.

Following a short introduction, this first discusses strawberry and other soft fruit picking robot developments conducted principally by commercial organisations. It then provides similar details of robots for harvesting apples and other hard fruits. This is followed by a discussion and concluding comments.

The shortage of seasonal fruit pickers has stimulated the need for automation. Accordingly, a growing community of companies, many founded in the past five years, are developing fruit picking robots. These are aimed at both soft and hard fruits, such as strawberries and apples, respectively, and exploit advanced vision systems, image processing techniques and AI. Some products are already on the market, whereas many more are due for commercial release during the next two years into what is expected to be a highly competitive market.

This provides details of the emerging fruit picking robot business by describing the products and manufacturing companies.

Few will complain that 1974 has not been an eventful year; in a number of significant respects, it has made history. Local Government and National Health Services reorganizations are such events. This is indeed the day of the extra‐large authority, massive monoliths for central administration, metropolitan conurbations for regional control, district councils corresponding to the large authorities of other days; and in a sense, it is not local government any more. As in other fields, the “big batallions” acquire greater collective power than the total sum of the smaller units, can wield it more effectively, even ruthlessly, but rarely appearing to take into account the masses of little people, the quiet people, who cannot make themselves heard. As expected, new names of authorities are replacing the old; new titles for departments and officers, ambitious and high‐sounding; a little grandiose for the tongues of ordinary folk. Another history‐making event of 1974, in the nature of a departmental transfer but highly significant for the course of future events as far as work in the field is concerned, was handing over of the personal health services—health of expectant mothers, babies, children, domiciliary midwifery, the school health services and their mainly medical and nursing personnel—from local health authorities to the newly created area health authorities. The public health departments over fifty years and more had created them, built them up into the highly efficient services they are. If anything can be learned from the past, new authorities are always more expensive than those they replace; they spend freely and are lavish with their accommodation and furnishings. In their first few months of existence, the new bodies have proved they are no exception. News of their meetings and activities in many areas is now scanty; even local newspapers which usually thrive on Council news—or quarrels—seem to have been caught on the wrong foot, especially in the small towns now merged into larger units. The public are relatively uninformed, but this doubtless will soon be rectified.
