Market opportunity recognition in the Chilean wine industry: traditional versus relational marketing approaches

The aim of this paper is to examine how wine firms implement their marketing strategies based on the recognition of market opportunities by their Chief Executive Officers (CEOs). Firstly, we describe the marketing activities in 69 traditional Chilean wine firms. Then, in-depth interviews with CEOs of two wineries are analysed using cognitive maps to uncover the cognitive processes responsible for recognizing and executing market activities. Our findings indicate that there is a similar set of strategic resources across the wineries, but the CEOs’ different perceptions of the usefulness of these resources in the implementation of marketing strategies have led them to select diverse strategies to increasing both the price per bottle and wine sales. This paper makes two contributions. Firstly, we compare the benefit of implementing traditional and relational marketing strategies in the Chilean wine industry. Secondly, we show that the CEOs’ perception of feedback processes among the available resources affects the recognition of market opportunities and the marketing strategy in wine firms.     

Cooking methods of Brassica rapa affect the preservation of glucosinolates,phenolics and vitamin C

Cooking Brassica vegetables as a domestic processing method has a great impact on health-promoting bioactive compounds: glucosinolates (GLS), flavonoids, hydroxycinnamic acids, and vitamin C. In Galicia (NorthWestern Spain), one of the most consumed horticultural crops is Brassica rapa, by using the leaves (turnip greens) and the young sprouting shoots (turnip tops) in different culinary preparations. In order to determine the effect of cooking, on turnip greens and turnip tops, bioactive GLS, flavonoids, hydroxycinnamic acids and vitamin C were analysed and simultaneously determined. The level of retention of each individual compound after cooking procedures was evaluated in the edible organs, and also in the cooking water, in order to compare their composition to a fresh uncooked control. Steaming, conventional boiling, and high-pressure cooking, traditional processing methods of this kind of vegetables, were the three domestic processing methods used in this work. Results showed that total GLS and phenolics were significantly affected by the cooking procedure and the loss rate varied among individual compounds. Steaming was the method that better preserved GLS and phenolic compounds. Conventional boiling and high-pressure cooking methods presented similar rate of losses of total GLS content (64%) and total phenolic content (more than 70%). Degradation among glucosinolate classes, aliphatic or indolic, was similar. The total flavonoids lost in turnip greens were 64% and 67% for conventional boiling and high-pressure, respectively. The main losses were caused by leaching into the cooking water. The concentration of vitamin C suffered a drastic loss in the process of sample handling and after cooking. Despite the fact that any cooking procedure affected negatively the nutritional composition of the turnip greens and tops, our results showed high retentions of individual compounds in steaming, and the lowest retentions were obtained in the traditional high-pressure cooking. High retention of health-promoting compounds in the cooking water should be considered for increasing the intake of properties of B. rapa.     

Physiological behavior and quality traits during fruit growth and ripening of four Amazonic hot pepper accessions

BACKGROUND: Skin color, acid content and changes in other chemical components have been developed as indicators of maturation in fruits of the Capsicum type. RESULTS: Fruit growth and ripening in four hot pepper accessions (CS) from C. frutescens (CS376) and from C. annuum (CS219, CS049 and CS032) were monitored in three commercial Colombian Amazonic orchards. The time between fruit setting and commercial pepper fruit maturity was 41 ± 5 days for CS219, while CS032, CS049 and CS376 required 47 ± 3 days. Three stages of development were identified. The first stage was cell division in the accessions and a transient peak in respiration rate in CS049. A second stage of fruit growth occurred due to maximum cell expansion and some transient peaks of respiration rate also took place. Finally, a plateau occurred as fruit reached full maturity and followed typical non‐climacteric behavior. CS032 and CS219 were pungent with increasing levels of alkaloids (capsaicin and dihydrocapsaicin) during fruit growth, although CS376 with its constant and higher levels of the former capsaicinoids early in fruit growth was not pungent, and neither was CS049. Morphological traits and fresh and dry weight together with color coordinates could be used to discriminate among accessions as revealed by two axes of the canonical discriminant analysis (99.9% total variance explained). CONCLUSIONS: In general, the time from fruit set and the apex skin color changes and accompanying morphological traits, were reasonable indicators of maturity in Amazonian hot pepper fruits. Multivariate analysis was able to discriminate among accessions. Copyright © 2008 Society of Chemical Industry
