Abstract

Purpose

A healthy and easy-to-use orange snack obtained from the freeze-dried orange pulp puree is proposed. Once the commercial packaging of the snack has been opened, the effect of conventional home storage temperature on its physicochemical properties and on the content of bioactive compounds has been studied. This research aims to recommend the consumer, and therefore the manufacturer, the best conditions for home storage of this product, keeping its nutritional quality and antioxidant capacity, as well as maintaining its colour and crispness.

Design/methodology/approach

The water content, water activity, hygroscopicity, crispness, colour, vitamin C, β-carotene, total phenolic compounds and antioxidant activity were characterised both when the orange snack was newly obtained and after one, two and six months of storage inside zipper bags, at 4 and 20 ºC.

Findings

The results indicated that, in these conditions, the orange snack increased its water content, causing a loss in both its porosity and its characteristic crispness. Nevertheless, the bioactive compounds remained stable throughout the storage period, with the exception of β-carotene, the content of which decreased markedly when the orange snack was stored at 20 ºC.

Originality/value

Few studies have evaluated the stability of food products during home storage. The findings showed that the maximum storage time to ensure a proper texture of the orange snack studied is between two and six months, both at 4 and 20 ºC. However, from the point of view of the conservation of both vitamin C and, especially, of β-carotene, it is recommended that this product be stored in refrigeration.

Abstract

Synopsis

Case study research frequently includes collecting and interpreting stories individuals tell about their lives and event that they believe that they know about. Chapter 3 discusses storytelling theory and describes case study research in consumer behavior of stories that consumers tell about buying and using products and services. Storytelling is pervasive through life. Much information is stored, indexed, and retrieved in the form of stories. Although lectures tend to put people to sleep, stories move them to action. People relate to each other in terms of stories — and products and brands often play both central and peripheral roles in their stories. To aid storytelling research in consumer psychology, this chapter develops a narrative theory that describes how consumers use brands as props or anthropomorphic actors in stories they report about themselves and others. Such drama enactments enable these storytellers to experience powerful myths that reflect psychological archetypes. The chapter includes findings from case study research that probes propositions of the theory. Implications for consumer psychology and marketing practice follow the discussion of the findings.

Abstract

This chapter highlights an overemphasis and persistent bias in entrepreneurship pedagogy toward predictive logic that results in unidimensional instruction. In contrast, we explore how to teach a creative logic for entrepreneurial action. We argue that a more realistic and complete approach to teaching and pedagogy should include a creative logic that will augment existing methods focused on students’ research and analysis and balance these with taking explicit entrepreneurial action. Building upon social capital, networking, learning and real options theories, the chapter uses case studies and provides in-class exercises to illustrate our perspective and help researchers and instructors alike.

Abstract

Purpose

Seeds to Success naturally grown gourmet salad greens, a product recognized for superior freshness, flavor, and quality, placed a community non‐profit organization in a position where high demand and limited production capacity became a major obstacle at a time when this nonprofit was facing tough decisions. The purpose of this paper is to present this example as a teaching case. The case also represents an example of the funding plight facing many community organizations and how social entrepreneurship can lead to creative solutions.

Design/methodology/approach

The information presented in this case is the result of years of participation and observation within the featured organization along with the cooperation of its employees, participants, and volunteers.

Findings

The analysis and discussion of facts and events presented are in the hands of the readers and the findings can be many.

Originality/value

This case can be of value for courses of many disciplines, as well as to serve as an example for practitioners involved in non‐profit organizations. As a teaching case, this study provides a unique history of events and description of the situation, as well as a chance to offer and discuss many possible solutions; each with its own potential set of contingencies. The case also allows readers to contrast the decision‐making considerations of for‐profit and non‐profit organizations as this community organization makes business decisions while protecting its social mission.

Abstract

This case describes the process that entrepreneur Paul Farrow went through to establish his kayak company between 1992 and 1996. After being laid off from a more traditional corporate position, Farrow came across an idea that suited his business skills, experience, and values. The case chronicles the steps he took to be the first in the industry to design and produce an inexpensive, high-performance recreational kayak from recycled plastic materials. Key to Walden Paddlers' $1-million sales in 1995 was the company's ability to forge close alliances with key suppliers and customers while keeping fixed costs down by managing a virtual corporation.

Abstract

Purpose

This paper aims to identify the factors that have led the USA to be one of the few countries in the world that has seen interlending and document supply continue to increase.

Design/methodology/approach

The factors are identified, reviewed and assessed.

Findings

It was found that the effectiveness of resource sharing facilitated by intra‐ and inter‐state cooperatives using OCLC as a framework is a major factor, others being the improvement in discovery tools, requesting processes and the more recent improvements in the delivery process. Finally, the widespread subsidizing of access and delivery enables cheap or even free use of document supply.

Originality/value

This paper is the only study so far that addresses the current puzzle of US “exceptionalism” for interlending and document supply.

Abstract

Southeast Asia has been actively undergoing land conversion into agricultural lands over past few decades. This creates the challenges to the nation in dealing with the non-point source pollutants in many fluvial systems, thus requiring an effective approach in sediment source apportionment for an appropriate target mitigation procedure. The trace element property from different source points was used for catchment classification of Galas River. Sediment sample collection was carried out at the sources and sink areas of the catchment system. Fine sediment was analysed using X-ray fluorescence to obtain elemental composition followed by the statistical test and numerical model. Out of 83 elements, 12 elements (Mn, Ca, Cr, Ga, Dy Hf, Y, V, Th, Pb, Zn and Sr) have been selected as best tracer signatures. The solver model has indicated Pergau River as the major sediment contributor to this large catchment system. The model output could directly be proportional with the land-use practice, indicating excessive terrestrial alteration has taken place within the sites for agricultural plantation purposes. Thus, this highly recommends for the decision-making use to the targeted areas to overcome the serious sedimentation issues caused by the tillage operation in affected stream points and to improve the watershed quality.

Abstract

Purpose

To report and analyze transaction data over a four‐year period for patron‐initiated borrowing via the Cascade union catalog as well as transaction data for traditional ILL in a consortium of six academic libraries in Washington State.

Design/methodology/approach

Transaction data for patron‐initiated borrowing via the Cascade union catalog were gathered from statistics produced by the Inn‐Reach software. Data for ILL were collected via a survey of libraries’ staff. Data for returnables and copies were analyzed at the consortium and institutional level.

Findings

In the third year of patron‐initiated borrowing, traditional ILL transactions for returnables had decreased 21 per cent consortium‐wide, the total number of transactions for returnables had increased 271.9 per cent, and the transactions for copies remained steady. Although the borrowing and lending patterns at the six libraries varied, each loaned and borrowed more returnables via patron‐initiated borrowing than via traditional ILL.

Research limitations/implications

This study describes activity at a single consortium of only six libraries. Since the Cascade libraries have now merged into a larger consortium, the Orbis Cascade Alliance, it would be interesting to collect and analyze new data from the larger group to see if patterns have changed.

Practical implications

The increased volume of returnables delivered to users in this consortium suggests that patron‐initiated borrowing is an effective method for resource sharing. Traditional ILL remains a necessary alternative for copies and books not available within the consortium.

Originality/value

This is the first study to examine consortium‐wide transaction data for both patron‐initiated borrowing and traditional interlibrary loan for a sustained period of time.

Abstract

Purpose

This study aims to examine the effects of various physical and chemical pre-treatments on antioxidant properties of tree bean (Parkia roxburghii G. Don) in combination with storage conditions.

Design/methodology/approach

The whole pods and seeds of tree bean were treated with gamma rays (γ-rays), sodium hypochlorite (NaOCl), chlorine dioxide (ClO2) and hydrogen peroxide (H2O2) and stored at room temperature (RT, 25°C) for 30 days. The physical and chemical pre-treated seeds and pods were compared with the same stored at RT and refrigerated storage at 4°C and −20°C. During storage, physical (moisture content) and antioxidants like total phenolics, ascorbate content, reduced glutathione, total flavonoids, along with free radical scavenging activities (FRSA) were measured.

Findings

Chemical pre-treatments with NaOCl, ClO2 and H2O2 significantly accelerated (p = 0.05) the total phenolics (1.9 mg/g FW in seeds and 2.4 mg/g FW in pods), flavonoids content (0.3 mg/g FW each in seeds and pods) and ABTS activities (73.3 per cent in seeds and 92.3 per cent in pods) at 30 days of storage. A significant decrease (p = 0.05) in ascorbate content (6.1 mg/g FW in seeds and 3.5 mg/g FW in pods), reduced glutathione (5.1 mg/g FW in seeds and 3.7 mg/g FW in pods), FRAP (0.3 mg equi Fe/g FW in seeds and 0.4 mg equi Fe/g FW in pods) and reducing power (1.8 mg/g FW in seeds and 3.7 mg/g FW in pods) was observed under all the treatments at 30 days of storage. However, DPPH increased under γ-irradiation and decreased under chemical pre-treatments, storage at RT and refrigerated storage. The overall result showed that pre-treatment of H2O2 at 10-20 mM maintains antioxidants and radical scavenging activities in tree bean during storage.

Originality/value

The application of H2O2 at 10-20 mM prior to storage of tree bean maintains the physical, antioxidant properties and FRSA in tree bean seeds and pods as compared to natural ambient conditions. Hence, this technique will help in improving the keeping quality of this legume and avoid spoilage after harvest for an extended period.

Abstract

Purpose

Staling, the progressive non‐microbial deterioration of quality, is influenced by baked product fat, sugar and moisture levels. Although 50 percent sugar replacement with an acesulfame‐K‐dextrose blend, and/or 50 percent fat replacement with dried plum puree, produces acceptable oatmeal and chocolate chip cookies within one day of baking, flavor and texture changes with continued storage are unknown. The purpose of this paper is to profile three oatmeal and chocolate chip cookie formulations.

Design/methodology/approach

Three oatmeal and chocolate chip cookie formulations (control, reduced‐in‐fat (50 percent) and reduced‐in‐fat and sugar (50 percent)) were profiled 1, 3, 5 and 7 days post‐bake by a trained sensory panel (n=8) using the Spectrum®‐approach on 0‐15 point linescales; three replicates were obtained. Water activity was determined on six replicates. Data were analyzed with PROC Mixed and PDIFF (p<0.05).

Findings

Water activity increased with modification; increases (aW<0.60) do not support microbial growth. Day 1 flavor and texture reformulation effects mirror those previously reported. Storage effects across all formulations (p<0.05) on oatmeal and chocolate chip cookie sensory attributes are within one linescale unit. Different significant (p<0.05) formulation×storage interactions suggest staling patterns differ with cookie type. Water activity increased during storage for chocolate chip cookies only; practical significance is questionable. Panelists' comments suggesting oxidative effects for both controls by day 5 are consistent with water activity.

Originality/value

Consumption of products with improved nutritional profiles can assist consumers in bringing their diets in‐line with dietary recommendations. Maximizing benefits requires continued selection of modified rather than non‐modified products. Technical issues (sensory characteristics, nutritional profile and storage convenience) do not appear to limit consumer selection of these reformulated cookies.
