Abstract

Rapeseed is the only oilseed crop grown in the UK. This is now Britain's third largest arable crop with a total area of over 200 thousand hectares. Production of the seed has risen consistently and dramatically from 0.13 million tonnes in 1977 to 0.58 million tonnes in 1982. The dramatic rise in the crop is apparent from the wider spreading of golden yellow flower fields in our countryside during the spring. Last year, however, seed production was about 5% down due to a small decrease in yield of about 1 tonne/acre, on average. World production of rapeseed and mustard seed (related members of the Cruciferae family: B. campestris, B. napus and B. juncea) has also expanded over the last decade, and the combined crop now lies fifth in oil‐bearing seed production and ranks fourth in the world supply of edible vegetable oils after soyabean, palm and sunflower oils. As a result of EEC support for the crop, production of rapeseed in 1982 rose by 35% to 2.7 million tonnes in EEC countries.

Abstract

In May 1981, disease broke out in Spain and quickly became of epidemic proportions, although the incidence of the disease was limited to a relatively small area around Madrid. The most commonly reported symptoms were fever, respiratory distress, nausea and vomiting, headaches, various skin eruptions, general discomfort, abdominal pain, and myalgias. The respiratory distress was initially the major symptom but later neuromuscular changes predominated, ranging from simple myalgia to muscular weakness and atrophy involving peripheral neuropathy, severe weight loss, scleroderma‐like skin changes, and pulmonary hypertension. The epidemic affected more than 20,000 people in Spain and claimed about 400 lives between May 1981 and October 1983. Afflicted patients are still dying, and it is feared that the eventual death toll may exceed 500.

Abstract

Oxidative quality of the oil. The average linoleic acid (C18:2, n‐6) content, measured in several suspect oils, was 42% of the total fatty acids. The peroxide values of the oil samples were high (18 to 57 mEq/kg) compared with those of olive oil (9.8 mEq/kg) purchased locally in Spain. The samples were very susceptible to oxidative deterioration, indicating a low content of the natural antioxidants, tocopherols (Vitamin E). The oxidative stabilities of the oils measured by the AOM test were generally low. There are no data available on the concentrations of tocopherols, pro‐oxidant trace metal (eg copper and iron) contents, levels of polyunsaturated fatty acids or hydroxy and epoxy derivatives in the suspect oils.

Abstract

The Ministry of Agriculture, Fisheries and Food is at present considering comments from the food industry, consumer groups and other interested parties on their draft regulations on fat content labelling of food. It is hoped that the regulations, which will require the total fat and saturated fat contents of most foods to be clearly indicated to the consumer, may be put to the House before the summer recess. The regulations may then be introduced at the beginning of 1987 and become mandatory one year later.

Abstract

Purpose

Chronic feeding with thermoxidized palm oil causes tissue damage. The purpose of this paper is to ascertain whether chronic feeding of oxidized and fresh palm oil affects biliary secretion.

Design/methodology/approach

Albino Wistar rats were divided into three groups of ten rats each. The first group was the control and were fed on normal rat chow, while the second (FPO) and third group (TPO) were fed diet containing either fresh or thermoxidized palm oil (15per cent (w/w)) for 14 weeks. Biliary secretion, bilirubin, electrolytes, cholesterol and serum levels of alkaline phosphatase, aspartate aminotransferase and alanine aminotransferase enzymes were measured.

Findings

Biliary secretion in TPO was significantly (p < 0.05) lower compared with the control or FPO. Electrolytes (Na+, Cl and HCO3) content of bile were significantly (p < 0.05) lower in TPO compared with control or FPO group. Conjugated and un‐conjugated bilirubin levels were significantly (p < 0.05) elevated in TPO compared with control or FPO. The levels of serum liver enzymes were significantly (p < 0.001) higher in TPO than control or FPO. The cholesterol level in the TPO was significantly higher (p < 0.001) than in control or FPO.

Research limitations/implications

The non‐clinical approach and use of experimental animals present limitations to the study.

Originality/value

These results suggest that long‐term feeding of thermally oxidized palm oil alters bile composition and decreases biliary flow due to its hazardous free radicals.

Abstract

Purpose

The purpose of this paper is to characterize oils extracted from Bertholletia excelsa, Lecythis pisonis, Dipteryx lacunifera, Carya illinoensis and Juglans regia, regarding their characterization and fatty acid profile.

Design/methodology/approach

The oils were extracted from oilseeds by cold pressing and physico‐chemical characterization was performed by using standard methods for oils and fats. The oxidative stability and fatty acid profile also were determined.

Findings

According to the results, the physico‐chemical properties of oils from nuts and walnuts were comparable to those of good quality conventional oils. The oil seeds are a good source of unsaturated fatty acids, especially oleic and linoleic acids.

Research limitations/implications

Implies the identification of fatty acid profile and physico‐chemical properties of oils extracted from nuts and walnuts, and to prevent certain types of diseases.

Originality/value

The paper identifies a new source of essential fatty acids extracted from oilseeds.

Abstract

Investigates the differences in protocols between arbitral tribunals and courts, with particular emphasis on US, Greek and English law. Gives examples of each country and its way of using the law in specific circumstances, and shows the variations therein. Sums up that arbitration is much the better way to gok as it avoids delays and expenses, plus the vexation/frustration of normal litigation. Concludes that the US and Greek constitutions and common law tradition in England appear to allow involved parties to choose their own judge, who can thus be an arbitrator. Discusses e‐commerce and speculates on this for the future.

Abstract

Governance is becoming an increasingly important concept in European theoretical debates and in political practice as a new way to manage public policies, since the public sector reforms in the 1980s. However, the debate in Latin America has different characteristics than in Europe, so it is necessary to provide a critical review of the proposed agenda for the transformation of the state in the region, and of the transfer of the concept of governance by multilateral agencies. To understand these changes, this chapter examines three key areas of reforms in Latin America and the privatization of public services, new social policy proposals, and the decentralization process. This will help us understand the tension between normative models and specific patterns of governance that prevail in Latin America.

Abstract

Purpose

Chili pepper pods are a worldwide used and cultivated spice with a high economic and cultural importance. Bolivia is a center of origin and diversification of important crops including wild pepper varieties, but little is known about the chemical composition, antioxidant activity and the Scoville and bioactive compounds of these chili peppers. The purpose of this study was to contribute with new data about the chemical composition and the Scoville scale of Bolivian Chili peppers.

Design/methodology/approach

A total of 26 samples of Bolivian Chili peppers were extracted using distilled water and methanol. Total antioxidant capacity was determined by the ferric-reducing antioxidant power (FRAP) and by the 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) methods. The total phenolic content was determined by Folin and Ciocalteu. Carotene, protein and ashes were determined by Bolivian analytical norms. Capsaicin was determined by high-performance liquid chromatography. All determinations were expressed as mean values± standard deviation of six replicates measured over three days of one extract. All values were less than 5% of coefficient of variation. Principal component analysis was applied to reveal patterns in the data. PC1 and PC2 together explained 78% of the total variance.

Findings

The protein content (3.8–6.3 g/100 g of dw) and the antioxidant activity (88.2 to 374 by FRAP and 87.0 to 172 evaluated by ABTS) studied in these species revealed that the values were above the average reported in the literature. The amount of pungency or capsaicin content expressed as Scoville Heat Units were reported moderately highly and very highly pungent (5,696–148,800 g dw) in several of the Bolivian peppers which demonstrates a good potential for capsaicin extraction and different applications for industry and as food ingredients.

Originality/value

This manuscript presents an important and novel contribution to the knowledge of the chili peppers in the region.
