Abstract

Purpose

The purpose of this paper is to encapsulate vanilla extract by using inclusion complex of ß-cyclodextrin and also to investigate the qualities of the encapsulated powder in terms of vanillin content, moisture content, and stability under accelerated condition.

Design/methodology/approach

A randomized block and factorial 3×3 experimental designs with three replications were used for the studies of solvent extraction, microencapsulation of natural vanilla extract and stability of microencapsulated vanilla powder.

Findings

Ethanol concentration and ratio of vanilla to ethanol had positive effects on vanillin content. The extraction with 55 percent ethanol and the ratio of vanilla pods to ethanol as 1:4 provided the highest vanillin content of 341.23 mg/100 mL of the extract. The amount of vanilla extract and kneading time gave significant (p<0.05) effect on the microencapsulation efficiency (ME). The greatest ME found was 94.50 percent when 9 percent vanilla extract and 10 min of kneading time were used. The interaction of temperature and water activity gave significant effect on the second-order kinetic reaction of encapsulated vanilla powder (p<0.05).The most suitable condition of storage was 35°C with aw of 0.64, providing the kinetic constant (k) of 0.0024, and correlation coefficient (R2) of 0.92 with thalf-life of 4.54 weeks.

Originality/value

This study provides the most suitable condition for natural vanilla extraction and microencapsulation as well as storage stability for natural vanilla powder production using the third grade vanilla pods grown at Royal Project, Khun Wang Center, Chiang Mai, Thailand.

Abstract

Purpose

The purpose of the paper is to correct a commonly mistaken notion that an Asian option is always cheaper than its plain vanilla European counterpart in a general setting.

Design/methodology/approach

The paper shows that by letting volatility go to zero, the lower bounds of Asian options and vanilla options are derived. Those bounds are then compared.

Findings

The paper finds that the notion can be violated for call options when the dividend yield of the underlying stock is higher than the interest rate, as well as for put options when the dividend yield of the underlying stock is lower than the interest rate.

Research limitations/implications

The approach used in this paper, boundary analysis, can be applied to other exotic options.

Practical implications

The results in the paper may affect decisions on trading Asian options.

Originality/value

The paper will be of value to those interested in using/pricing/hedging Asian options.

Abstract

The Virginia Tech Library System is an integrated library system supporting cataloging, authority control, serials control, circulation, reserve room, acquisitions, document delivery, online public‐access catalog, keyword searching with Boolean operators, and statistics reporting. It runs on the Hewlett‐Packard HP/3000 line of computers. Initially installed in 1975, there are currently 104 users. Sidebars discuss: The Vanilla Network; LINNEA—the library information network for Finnish academic libraries; and the statewide information and referral service at Cabell County Public Library (West Virginia).

Abstract

Purpose

The purpose of this review is to address the consumer’s preferences that have varied greatly in the past decade appraising the use of flavor and aroma compounds in the development of functional foods rather than consuming artificial additives. A growing interest in natural flavoring agents and preservatives have made the researchers to explore the other bio-functional properties of natural flavors beyond their ability to give a remarkable flavor to the food.

Design/methodology/approach

In this review, five major flavoring agents used significantly in food industries have been discussed for their bioactive profile and promising health benefits. Vanilla, coffee, cardamom, saffron and cinnamon, despite being appreciated as natural flavors, have got impressive health benefits due to functional ingredients, which are being used for the development of nutraceuticals.

Findings

Flavoring and coloring compounds of these products have shown positive results in the prevention of several diseases including carcinoma and neurological diseases such as Alzheimer’s and Parkinson’s. Such effects are attributed to the presence of phenolic compounds, which possesses free radical scavenging, anti-inflammatory antiviral and antimicrobial properties. These properties not only show a preventive mechanism against diseases but also makes the food product shelf-stable by imparting antimicrobial effects.

Originality/value

This paper highlights the opportunities to increase the use of such natural flavoring agents over synthetic aroma compounds to develop novel functional foods. Phenols, carotenoids and flavonoids are the major health-promoting components of these highly valued aroma ingredients.

Abstract

This research applies a static hedging portfolio method derived from Derman, Ergener, and Kani (1995) (henceforth Derman's SHP method) and a new SHP method with European cash-or-nothing binary options developed by Chung, Shih, and Tsai (2013) to price European continuous double barrier (ECDB) options and the rebates of the ECDB options. Our numerical results indicate that the new SHP method outperforms Derman's SHP method in terms of efficiency and effectiveness under all circumstances.

Abstract

The objective of this research is to develop a model to forecast sales for an ice-cream company. In order to achieve this objective, we evaluate sales data of three ice-cream flavors namely vanilla, chocolate, and Tally Ho (mixture of chocolate and vanilla) from January 2016 to 25 November 2019. To determine which model worked the best, we tested different models such as moving averages, simple exponential smoothing, Holt's method, Winters' method, method modeling seasonality and trend, and an ensemble method. We found Winters' method and modeling seasonality and trend performed well in terms of lowest error rates compared with other methods.

Abstract

Mr. LEVENSTEIN, the President of the Society of Chemical Industry, in his address delivered at Liverpool recently, dealt very fully with the question of the commercial position of Great Britain as compared with other countries, more especially Germany, and emphasised the fact that if this country is to compete successfully with her contemporaries she must, to use the words of the Prince of Wales at the Gúildhall, “wake up.” After reviewing the chief factors making for Germany's advance in industry and commerce Mr. LEVENSTEIN says: “How are we to defend ourselves? Shall we rest content as we are or bestir ourselves and awake to the irresistible fact that continued apathy and indifference mean ruin to our national position?” This is strong language but not stronger than the occasion demands, for the statistics by which these observations are backed clearly indicate a marked decadence in the national prosperity notwithstanding the years of apparent “record” trade, which, however, cannot be regarded so favourably when subjected to detailed analysis and comparison. Mr. LEVENSTEIN'S suggestions to meet this situation are as follows: (1) The appointment of a competent and expert Minister of Commerce. (2) The nationalisation and extension of our canals and waterways. (3) A measure for greatly extending and improving our secondary education. (4) A sensible reform of our patent laws.
