Abstract

Purpose

Visible and near infrared spectroscopy have been applied widely in fruits quality assessment especially on the measurement of soluble solids content (SSC) measured in oBrix and acidity measured in pH. Spectroscopy technique has been applied on three botanically different categories of fruits, that is: imported Californian table grape, Mandarin lime and star fruit. The purpose is to examine the ability of spectroscopy technique to quantify internal quality parameters with very narrow variability due to the characteristics of the raw material analyzed. This work also presents comparative study on peak wavelengths that can best be used to calibrate SSC and pH of different types of fruits.

Design/methodology/approach

The effective wavelengths chosen for calibration development are compared with those selected by other researchers in similar experiments. NIR wavelengths 910 nm (C−H band) and 950 nm (O−H band) are the most important wavelengths for the prediction of SSC for all examined fruits while wavelengths 922‐923 nm and 990‐995 nm for pH. Visible wavelength 605, 675 and 654 nm can efficiently improve the SSC and pH prediction for grape, lime and star fruit, respectively.

Findings

The best prediction for SSC has been achieved with R2=0.953 and RMSE=0.182 for grape, R2=0.918 and RMSE=0.109 for lime and R2=0.957 and RMSE=0.354 for star fruit. The best prediction for pH has been achieved with R2=0.763 and RMSE=0.110 for grape, R2=0.841 and RMSE=0.073 for lime and R2=0.862 and RMSE=0.261 for star fruit.

Originality/value

Currently, the spectroscopy research conducted for the measurement of fruits qualities is conducted through wide range spectrometer. However, the peak responses are only located at specific wavelengths. Hence, the selection of wavelengths related to SSC and pH will allow the design of low cost instruments for the prediction of these internal quality parameters.

Abstract

Two anthraquinone compounds are extracted from culture filtrates of Fusarium oxysporum isolate no. 4, which were previously isolated from roots of citrus trees affected with root rot disease. These anthraquinone compounds were identified as 2- acetyl- 3,8- dihydroxy- and/or 3-acetyl- 2,8- dihydroxy- 6- methoxy- anthraquinone. Dyeing of cationized cotton fabrics with these anthraquinone compounds as natural dyes has been studied. The values of the dyeing rate constant, half-time of dyeing and standard affinity have been calculated and discussed. The results of the dye uptake isotherms of cationized cotton fabrics dyed with these compounds indicate high dye uptake and the standard affinity of cationized cotton fiber is higher. The toxicity assay of culture filtrates as well as anthraquinone pigment extracted from Fusarium oxysporum against root growth (seed germination) of citrus seeds is investigated. Seeds of sour orange are more affected by all tested concentrations of anthraquinone compounds as well as culture filtrates of Fusarium oxysporium than other citrus seeds. Seeds of lime and Cleopatra mandarin are less affected. The effects of dye bath pH, salt concentration, dyeing time and temperature are studied. Color strength and dye uptake exhibit high values. The results of fastness properties of the dyed fabric are good.

Abstract

The analyses of trends in prosecutions under the Food and Drugs Act, 1955 and the various regulations, which we have prepared every two years or so, covering a three‐month period, have been so much appreciated by readers, both in the administration and the industry itself, that we have prepared a more extended survey, covering the whole of 1966. The survey, as before, takes the form of a month‐by‐month analysis of reports of legal proceedings received by us from all parts of the country, and as formerly records the prosecutions under similar groupings; cases under Section 2, subdivided into those relating to compositional offences, the presence of foreign bodies and those relating to mouldy food: false description cases under Section 6 of the Merchandise Marks Acts; Section 8, the unfit food provision, also subdivided with special categories for foreign bodies and mouldy food; Section 32, milk cases; cases under the Food Hygiene Regulations, 1960, with smoking offences separated; the Milk and Dairies Regulations, consisting almost entirely of prosecutions under Reg. 27, Meat Regulations, Preservative Regulations, Colouring Matter in Food Regulations, etc.

Abstract

Purpose

Cloon Keen Atelier develops candle and skin care products. The challenge for this small operator is to develop a strategy, which reinforces its chosen position as it develops new products and expands into other markets. Cloon Keen is known for its premium scented candles, but it is seeking to expand into the personal care market by creating their own line of skin care products and complementary accessories. Cloon Keen believes their handcrafted candles could provide a platform for developing a lifestyle brand. This paper aims to address these issues.

Design/methodology/approach

In‐depth interviews and secondary sources are used to collate the information from which the case study is developed.

Findings

Achieving the status of a lifestyle brand means the products embody the values and aspirations of particular group(s) or culture; it speaks powerfully to the core identity of its consumers. Typically, lifestyle brands are accompanied by a powerful promotional campaign to communicate the lifestyle brand values to audiences. To date, Cloon Keen's promotional efforts have been limited. The question is whether it can develop sufficient market presence to one day make the claim of being a lifestyle brand. The challenge for Cloon Keen is to find the optimum market position that provides a strategic advantage in a climate of robust competition.

Originality/value

The case study provides the opportunity to examine how an small‐ to medium‐sized enterprises may build its brand presence within a highly competitive market.

Abstract

Purpose

The purpose of this paper is to investigate the fruit consumer segmentations and compare the consumption patterns across North America, Europe and East Asia. This study aims to identify the key drivers for fruit consumption across segments and regions, in terms of socioeconomics and shopping behavior.

Design/methodology/approach

An international survey to collect information on fruit consumption, demographics and lifestyle factors was developed. Respondents from eight countries across North America, Europe and East Asia were recruited from online panels. A total usable sample of 7,793 respondents was collected.

Findings

Respondents can be clustered in three segments: low-frequency consumer, common fruit consumer and high-frequency consumer. These consumer segments are heterogeneous in socioeconomics and shopping behavior across regions. Overall, the high-frequency consumer cluster had more individuals who were older, married, not single/never married, self-reported healthy and physically active. The low-frequency consumer group had a larger number of individuals who were younger, living alone, single/never married, self-reported unhealthy and not active. Moreover, the high-frequency fruit consumers tended to focus on many fruit attributes, such as freshness, nutritional value, origin and in the season, but not focus on the price.

Originality/value

This study uses a unique data set covering eight countries and provides a comprehensive comparison of international fruit consumption patterns and identifying the important factors driving fruit purchase decisions.

Abstract

Purpose

The purpose of this paper is to test the efficacy of the concept of food miles that has proved so popular with the public as a means of assessing the sustainability of produce.

Design/methodology/approach

This paper uses data from a UK major food importer and retailer to correlate carbon emissions from transport, and transport‐related storage, with food miles by creating farm‐specific mode‐weighted emission factors.

Findings

The correlation is found to be poor for a wide range of products and locations and it is clear that the mode of transport is as important as the distance, with sourcing from parts of the Mediterranean resulting in emissions greater than those from the Americas.

Practical implications

It is concluded that it is difficult to justify the use of food miles when attempting to influence purchasing behaviour. Because of this result, processes and tools have been developed that relay information on true transport‐related carbon emissions to customers and bulk purchasers that allow them to make informed decisions.

Originality/value

This paper questions the value of using the concept of food miles as a driving force for changing purchasing behaviour by either the customer or the purchasing department of a retailer.

Abstract

The succession of storms around the question of the disposal of the large quantities of corned beef called in or held up from the time of the Aberdeen Typhoid Epidemic can have done little to enhance the image of public administration. There was a profusion of statements, official and otherwise, and what seemed to be a fight between factions in the trade, with the position of the two Ministries involved none too clear; all this was thrown into a thorough ferment by political intervention by the Prime Minister himself. There can never have been anything quite like it in any branch of public health, not so much in what has been done, but in the way it was done.

Abstract

Reports on research into the level of consumer awareness of the attributes of citrus fruit. Claims it is necessary to convert consumer attitudes towards healthy eating into appropriate consumer behaviour. Hypothesizes that consumer knowledge of some important attributes of fruit and vegetable products is low, and that better informed consumers might make better informed purchasing decisions. Describes the methodology and results of the survey which finds evidence that consumers are largely ill‐informed about the attributes of the citrus fruit that they purchase.

Abstract

Purpose

The lack of food-based dietary guidelines for managing cancer among hospitalized patients has led to an increasing economic burden on the government and families in low- and middle-economy countries. There have been increasing medical costs due to delayed recovery, readmission and mortality. The purpose of this study is to contribute in reducing these effects by developing context-specific food-based dietary guidelines to assist health-care professionals and caregivers in planning diets for cancer patients.

Design/methodology/approach

For seven days, the dietary intakes of 100 cancer patients in the hospital were recorded using weighed food records. Data on the costs of commonly consumed foods during hospitalization were obtained from hospital requisition books as well as nearby markets and shops. The information gathered was used to create optimal food-based dietary guidelines for cancer patients.

Findings

Most patients did not meet the recommended food group and micronutrient intake according to their weighed food records. Sugar intake from processed foods was (51 ± 19.8 g), (13% ± 2%), and calories (2585 ± 544 g) exceeded recommendations. Optimized models generated three menus that met the World Cancer Research Fund 2018 cancer prevention recommendation at a minimum cost of 2,700 Tanzanian Shillings (TSH), 3500TSH, and 4550TSH per day. The optimal dietary pattern includes nutrient-dense foods from all food groups in recommended portions and within calorie limits.

Originality/value

Findings show that optimal dietary guidelines that are context-specific for managing cancer in hospitalized patients can be formulated using culturally acceptable food ingredients at minimum cost.

Abstract

Citrus fruits have a refreshing taste because of their high water content and presence of the weak but sharp tasting citric acid. Because they have a high water content, they have a correspondingly low energy content. The energy comes from the carbohydrates, fructose and glucose, as there is very little protein and no fat present.
