Abstract

Purpose

Bales of cotton run through the gins and textile mill instruments, stick to them and make it cumbersome for the ginning mill workers. This is so because more time and money have to be invested in cleaning these instruments. The stickiness of cotton causes health hazards to the workers, decreases the yarn quality and economic loss to the textile industry. The effect of cotton stickiness on textile ginning, various methods for cotton stickiness detection and the steps for reduction are discussed.

Design/methodology/approach

The different methods that are available for detecting and measuring cotton stickiness are described. The sugars that cause stickiness are either of plant origin (physiological sugars) or from the feeding insects (entomological origin). The methods for stickiness detection and reduction are discussed under physical, chemical and biological categories.

Findings

This review suggests possible ways to mitigate cotton stickiness.

Originality/value

One of the major issues of the textile industry is honeydew-contaminated cotton stickiness. However, there are few papers on detection methods for analyzing honeydew cotton stickiness along with the approaches to reduce stickiness. This paper summarizes different methods along with a study for detection as well as reduction of cotton stickiness.

Abstract

Children’s diets tend to be higher in sugars than those of adults, and parents often associate sugar with obesity. Contrary to this hypothesis, surveys of various age groups all tend to show an inverse relationship between sugars and body mass index (BMI). In the latest National Diet and Nutrition Survey of children aged 11/2 to 41/2 years, children with the lowest sugar intakes, or whose diets were lowest in biscuits and cakes, or table sugar and preserves, had the highest BMI. Over‐emphasizing the avoidance of sugars may, paradoxically, be counterproductive in preventing obesity. Due to the phenomenon known as the sugar:fat see‐saw, a diet low in sugars tends to be proportionately high in fat. It is concluded that there is little justification in limiting NME sugars to 10 per cent of energy, for the avoidance of obesity.

Abstract

Since 1981, the U.S. federal government has operated a price support program to help sugar beet and sugar cane producers and processors. This complex program works through a combination of loans, import quotas, and duties. As a result, sugar prices in the United States are significantly higher than world prices. For example, in December 2001, U.S. consumers paid 22.9 cents per pound, while the world price was just 9 cents per pound. The General Accounting Office estimates that the total cost to consumers is $1.9 billion a year. Uses a simple demand-and-supply framework with real-world data to assess the economic and political consequences of the U.S. sugar program.

To illustrate welfare concepts such as consumer surplus, producer surplus, and dead-weight loss in a concrete, real-world market context.

Abstract

Purpose

There is growing awareness internationally of the need to reduce intake of added sugars. The purpose of this study was to examine consumer sugar knowledge and food label use.

Design/methodology/approach

This cross-sectional online survey included 229 adult participants (85% female and 15% male). Participants completed measures of demographics, sugar knowledge, interest in food and nutrition, food choice motivations and beliefs and food label use. The sample of convenience showed that participants were from Australasia (n = 90), the USA (n = 90) and other Western (Europe and Canada, n = 49) countries.

Findings

Overall, participant sugar knowledge predicted nutrition label use over and above individual demographic and psychological characteristics (interest in food and nutrition, health beliefs and food choice motivations) (p < 0.001). Country comparisons revealed that those in Australasia reported lower sugar knowledge compared to the USA (p =< 0.001) and other Western countries (p = 0.028).

Research limitations/implications

Overall, participant sugar knowledge predicted nutrition label use over and above individual demographic and psychological characteristics (interest in food and nutrition, health beliefs and food choice motivations) (p < 001). Country comparisons revealed that those in Australasia reported lower sugar knowledge compared to the USA (p =< 0.001) and other Western countries (p = 0.028).

Originality/value

This study explored sugar knowledge as a unique predictor of food label use, taking into account individual characteristics in demographics, food choice motivations and health beliefs.

Abstract

While genetically modified (GM) crops have provided tremendous agricultural productivity gains, many consumers oppose GM products and maintain they are unsafe. We use the case of GM sugar beets and their adoption by the US producers to examine the implications of GM technology on food security. A partial equilibrium framework is used to examine the implications of GM technology on food security. This analysis provides a unique opportunity to examine the impact of GM adoption in one product (sugar beets) relative to non-GM adoption in a substitute product (sugarcane). This analysis examines the potential gains to food security through the adoption of biotechnology versus consumer fear of GM technology. Research and development (R&D) has potential implications not only through its impact on supply, but also on demand as well. This study shows that demand impacts can negate the supply-induced food security gains of R&D. Regulations such as mandatory labeling requirements can impact this outcome.

Abstract

While scholars have commonly inquired into how capital structures the material world, far less attention has been paid to how the material world has structured the historical relations of the capitalist world economy. This chapter is concerned with the expansion of Caribbean sugar industry in the world economic conjuncture of the first half of the nineteenth century. It examines the relation of the material requirements of sugar production, regional geography, and productive space. The ability of planters in particular locations to respond to world economic conditions was subject to material and spatial constraints. Increased output and technological innovation were dependent on the creation of new productive spaces – including both the formation of new commodity frontiers and the reconstitution the sugar plantation – that conformed to the changing requirements of sugar manufacture. Thus, the spatial and material conditions of staple production shaped the pattern of accumulation and political economic development.

Abstract

In this chapter the development of new sugarcane varieties in Florida and Louisiana is examined, along with the accompanying advancement in mechanization technology through the widespread adoption of sugarcane harvesters. An econometric analysis is carried out to determine the impact of the price of raw sugar on raw-sugar yields in Louisiana and Florida. This study found that in the case of Louisiana, the 3-year lagged US raw-sugar price had a positive and significant impact on sugar yields. The change in raw-sugar prices did not have a significant impact on sugar yields for the Florida industry. Sugar production has increased over time, in part, due to the development of new sugarcane varieties accompanied by modern sugarcane harvesters. Given the relationship between price and yield, particularly in Louisiana, policy makers and producers must be mindful of the potential impact of policy-induced research and development (R&D) on the competitiveness of their industry.

Abstract

Purpose

Prevention of chronic diseases by means of dietary modification can be achieved by consuming healthier foods with lower sugar content. However, reducing sugar content causes significant impact on the sensory quality and consumers’ acceptance towards local healthy products. This study aims to evaluate the effects of cross-modal interactions of Aroma-Taste-Texture (ATT) in yoghurt drink.

Design/methodology/approach

Fifteen sugar reduced yoghurt drinks [S, sugar percentage (0%, 2%, 4%); T, stevia dosage (0%, 0.01%, 0.02%); P, pectin dosage (0%, 0.3%, 0.6%)] based on ATT were evaluated by 300 consumer panellists on aroma, taste, texture and overall acceptability on a nine-point hedonic scale while sweetness intensity was measured using a seven-point just-about-right (JAR) scale. Interactions between ATT were determined.

Findings

Significant interaction was found between sugar and stevia, with F14 (4S0.02T0P) rated as sweeter than F4 (0S0.02T0P) (p = 0.003) and higher overall liking score than F11 (4S0T0P) (p = 0.001). Similarly, significant interaction was found between sugar and pectin, with F2 (0S0T0.6P) rated as significantly lower overall liking score and less sweet than F1 (0S0T0P) (p = 0.0001). Likewise, significant interaction was found between stevia and pectin, with F2 (0S0T0.6P) rated as significantly lower overall liking score and less sweet than F1 (0S0T0P) (p = 0.0001). Overall, F5 (0S0.02T0.6P) scored highest in overall liking and closest to the ideal sweetness (JAR = 4) indicating the possibility to apply 100% sugar replacement.

Originality/value

Application from the present study could be great potential solution in developing healthier range products while meeting consumer preference. The present study concluded that interactions of ATT of yoghurt drink will induce desirable changes in sensory and sweetness perception.

This paper aims to study how diabetics/pre-diabetics (D) and non-diabetic (regular consumers of sweeteners (C) or not (NC)) perceive and consume sweetened processed food in Brazil.

Abstract

Purpose

This paper aims to study how diabetics/pre-diabetics (D) and non-diabetic (regular consumers of sweeteners (C) or not (NC)) perceive and consume sweetened processed food in Brazil.

Design/methodology/approach

A cross-sectional study (n = 2,204) was carried out to gather information about: consumption of 14 sweetened food/beverage categories, perception of sugar/sweeteners (check-all-that-apply (CATA) test), understanding of sugar claims and socioeconomic/demographic/consume profile. Chi-square test/Fisher exact tests were used to analyze the contingency tables. CATA test results were evaluated using Cochran Q test, RV coefficient and Kruskal-Wallis test.

Findings

Results revealed that although diabetics/pre-diabetics consumed less sugary products than non-diabetics (p < 0.001), >50.0% of them preferred sugary candies, bakeries, ready-to-drink fruit juice, ice cream, chocolate and ready-to-eat desserts. D, NC and C similarly perceived (RV = 0.99) sugar (sensory desirable, but penalized due to its health impact), naturally extracted sweeteners (opposite description of sugar) and chemically synthesized sweeteners (penalized by sensory and health impacts). Regarding the claims, those that mean the absence of sugar were correctly understood for = 90.0% participants, while incorrect interpretations were observed for “containing sugars from own ingredients” (42.7%) and “light on sugar” (21.0%), without differences between consumer groups (p = 0.93).

Research limitations/implications

This study was carried out with a convenience sample.

Practical implications

Results can be applied to support food policies and educational campaigns (improving consumer information on processed sweetened foods) and to guide product development in the food industry.

Originality/value

This is the first study to evaluate the Brazilians’ behavior regarding the perception of sugar and sweeteners, the choice of different sweetened processed food, and understanding of sugar claims.
