Abstract

Purpose

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.

Design/methodology/approach

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.

Findings

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.

Originality/value

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.

Abstract

Purpose

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.

Design/methodology/approach

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.

Findings

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.

Originality/value

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.

Abstract

Purpose

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.

Design/methodology/approach

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.

Findings

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.

Research limitations/implications

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.

Practical implications

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.

Originality/value

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.

Abstract

Purpose

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.

Design/methodology/approach

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).

Findings

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.

Originality/value

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

Abstract

Purpose

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.

Design/methodology/approach

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.

Findings

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.

Practical implications

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.

Originality/value

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.

Abstract

Purpose

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.

Design/methodology/approach

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.

Findings

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.

Originality/value

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.

Abstract

Purpose

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.

Design/methodology/approach

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.

Findings

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.

Originality/value

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

Abstract

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.

Abstract

We can think of those with a cynical turn of mind who might consider not a little of the present output of the parliamentary machine as “harem scarem” law, but the indecent haste, the freak urgency of some politically inspired laws apart, it is only too obvious that law is being made under rush conditions, and the reasons are not far to seek. A hectic, over‐active party executive, feverishly pushing ahead with its policies produces impossible working conditions for the parliamentary draftsmen. Law, whether it is statute or regulation, has never been more complex than it is today; time allowed for parliamentary debate is completely inadequate; too many and varied interests have to be taken into account, to say nothing of the vast range of delegated legislation. The urgency of some legislation is doubtful; it is difficult to see the need for all the hurry; a little more time in proper debate would prevent some of the loopholes which subsequently appear and render the law more comprehensible; incomprehensibility and justice are rarely compatible. As Diplock L J., said in the Court of Appeal in Rex. v. Industrial Injuries Commissioner ex parte Cable (1968) 1 A.E.R., 9, a few months ago—“Judges have been at their wits' end to know what some of the provisions mean. It would be a good thing if time could be found to remedy the blemishes.”

Abstract

Scientists have often been accused of a desire to reduce the human diet to a pill or powder form “to be taken daily with water at meal times.” Whatever truth there might be in the allegation, it is an actual fact that more and more foods are being proved suitable for preservation in dried form. This is partially a logical development of the processes of food preservation, which are largely the concentration of food products for convenience in transport and storage, and partially the results of special war‐time demands. The need for concentrated nourishment is never greater than under conditions of war stress, and the present serious pressure upon Allied shipping facilities has further tended to increase the need for foods that occupy the least possible space. On the average, one pound of fully dehydrated food is the equivalent of fifteen pounds of the same product in its original form. Thirty dozen eggs in the shell, packed and created for shipment, occupy 2¼ cubic feet; dried, the same number take slightly more than one‐half cubic foot. The saving in ships and cargo space is obvious. While the problem of shipping space has been a major factor in the stimulated interest in dehydration, other elements in the existing situation have also had their influence. In Great Britain, under constant threat of invasion, it has been essential to build up reserve stocks of food throughout the country, often under storage conditions that are far from ideal. The serious shortage of tin has restricted the use of ordinary canning methods to foods which cannot, at the present stage of research, be preserved in any other form. A further stimulus has been given by the necessity of providing concentrated foods for paratroops and commando units, which must be entirely self‐sufficient when in action. Special rations are prepared which provide meals for two or three days, yet weigh only a few pounds. Drying is the oldest known form of food preservation, in fact it may be termed the natural method of preservation. Nature herself uses it. On the average, seeds, grains and nuts contain less than 10 per cent. of moisture, regardless of the amount which may be present at earlier stages of growth. The very existence of vegetable life from year to year is in the final analysis dependent upon this lack of moisture which inhibits the growth of bacteria and moulds. Perhaps by some accident, perhaps by imitation of the natural process, man early began to preserve food by drying, either in the sun or by artificial heat. Robinson Crusoe's raisins and the dried apples of our pioneer ancestors leap at once to the mind. Dried fruits and fish, jerked and smoked meats are all preserved by the removal of some part of their original water content. Sometimes this is the sole process, sometimes it is combined with other methods, as salting or pickling. In recent years, however, the preservation of foods by canning, refrigeration, and latterly by quick‐freezing has largely replaced the earlier method. Natural or artificial drying methods have in the past permitted the storage of food and the retention of a part of its nutritive value at the expense of flavour and colour. Everyone knows the difference between the flavour and texture of sweet corn in the milky stage and that which has ripened further, i.e., begun to dry out. In the case of such products we have largely come to prefer the dried flavour, even where we can know the so‐called fresh flavour. Some artificially dried or semi‐dried foods have, in fact, retained their place in the modern diet in direct competition with the fresh form, not as substitutes, but as independent food products in their own right. Such fruits as dates, figs, prunes and raisins are perhaps the best examples. No one expects raisins to take the place of grapes or prunes to have the same flavour as plums. These so‐called dried fruits are, however, really only semi‐hydrated. They retain from 20 to 25 per cent. of their moisture; only enough has been removed to ensure their keeping qualities. While they are a concentrated product, the process has not been carried to the point of complete transformation into the solid form. Jerked or dried meat and such products as pemmican are also among the oldest forms of preserved food, and jerked beef is still extensively produced in many countries. A more generally known form of meat product is meat extract. There are a number of famous brands, available either as a thick syrupy liquid or in a solid cube. The keeping property is implicit in its low water content, usually about 15 per cent. These extracts are prepared by removal of the fat and albumen, the addition of salt and evaporation in vacuum. One pound is ordinarily obtained from twenty‐five pounds of lean meat. Packing companies in the United States report that experimental methods of producing a true dehydrated meat, one which can be restored to its normal character, have been successful, at least in regard to beef. Pork is apparently too fat for such treatment. If the process works on a commercial scale as successfully as in the experiments, additional savings in shipping space will be realised. It is estimated that one ship could carry as much meat as ten cargo vessels were able to transport during the last war. Among other concentrated foods that go back to antiquity are the milk products, butter and cheese. These belong to the class which has little relation in either flavour or texture to the original from which they are made. Cheese is a product of fermentation as well as drying, while butter is additionally protected by salt and by refrigeration in storage and transport. Thus, while the removal of water is an important step in their manufacture, they cannot be considered dried foods. Recent reports from New Zealand indicate that butter is now entering this category. As a result of research which antedates the war, the New Zealand Dairy Research Institute has perfected a method of dehydrating butter. The British Government has contracted to purchase 20,000 tons during 1942 and 1943. A trial shipment of 400 tons was made last year and was well received. According to a report from the Canadian Trade Commissioner in New Zealand, the process was developed originally in order to reach markets not served by refrigerator ships. The dislocation of the shipping facilities between New Zealand and Great Britain has eliminated the usual means of sending butter. The new product, however, can be shipped as general cargo on any ship that may be available. The dried butterfat can be used directly by industrial food manufacturers and its conversion into table butter is simply adding a matter of water and salt. Not only will it serve a valuable war‐time purpose of providing Great Britain with needed fats, but it will also relieve the position of dairy farmers in New Zealand. After the war it is considered possible that the original purpose of marketing in countries without refrigerator service may continue to absorb available supplies.
