Abstract Hami melon fruit is highly appreciated for its unique flavor. How to simulate Hami melon flavor has rarely been reported. If the Hami melon flavor is developed, it can be widely used in food, beverages, and other products. Thus, Hami melon flavor creation is of great interests. This study dealt with Hami melon flavor creation in the light of note method. The notes for construction of a Hami melon flavor were obtained by tasting and smelling Hami melon fruity. Green note, sweety note, melon fruity note, other fruity note, winey note, and special note together form Hami melon flavor. Based on these notes, a series of aroma materials were selected to construct Hami melon flavor formula. After olfactory evaluation, numerous adjustments and modifications were made until a desired Hami melon flavor formula was obtained. The flavor blended based on the formula has the typical characteristic odor of natural Hami melon fruit. It has a fresh, sweet, harmonious Hami melon aroma.

Abstract As one of the major fruits, mango has a very attractive flavor characteristic, and is well known for its exotic flavor. Mango flavor has widespread application in beverages, ice-creams, foods and other products. However, flavor and fragrance formulas are usually trade secrets in flavor and fragrance industries. How to imitate and create mango flavor with the aroma materials has rarely been reported. In this paper, note method was used to imitate and create a mango flavor. The notes to construct mango flavor were identified by tasting and smelling mango fruits. Mango flavor is made up of sweety note, fruity note, milky note, acidic note, green note, floral note, herbal note, and sulfury note. On the basis of these notes, aroma materials were chosen, and an initial mango flavor formula was designed. After numerous adjustments and modifications, the desired mango flavor was successfully created, and the typical mango flavor formula was obtained. The mango flavor obtained has a typical characteristic aroma of natural mango fruit. It smells fresh and harmonious.

Abstract Pineapple is an aromatic tropical fruit and has attractive sweet odor. The aroma of pineapple is very popular and pineapple flavor has good prospects for application. Usually, flavor recipes are trade secrets. This paper deals with how to construct a pineapple flavor recipe and how to imitate a pineapple flavor with natural and synthetic aroma ingredients. By smelling and tasting pineapple fruit, the notes of pineapple flavor was identified as fruity note, winy note, vanilla-like note, vegetative note, beany note, sweet note and acidic note. In the light of the notes of pineapple flavor, the corresponding aromatic natural and synthetic ingredients having the same notes were choose to construct a pineapple flavor recipe. On the basis of the olfactory discrimination, the pineapple recipe was modified and adjusted for several times, and finally a desired pineapple flavor recipe was obtained. The blended flavor based on the recipe was harmonious and had typical natural odor characteristics of pineapple fruit.

Abstract Linalool has been extensively applied in various fields, such as flavoring agent, perfumes, cosmetics and medical science. However, linalool is unstable, volatile and readily oxidizable. A sensitive substance can be encapsulated in a capsule, so encapsulation technology can solve these problems. In this paper, linalool-loaded nanocapsules (Lin-nanocapsules) were prepared via the ionic gelation method and Lin-nanocapsules were characterized. The results of Fourier transformation infrared spectroscopy (FTIR) showed that linalool was successfully encapsulated in the wall materials. Scanning electron microscopy (SEM) results demonstrated that the shapes of Lin-nanocapsules, with smooth surfaces, were nearly spherical. Lin-nanocapsule average particle size was 352 nm and its polydispersity index (PDI) was proved to be 0.214 by the results of dynamic light scattering (DLC). Thermogravimetric results indicated that linalool loading capacity (LC) was 15.17%, and encapsulation could decrease linalool release and increase linalool retaining time under the high temperature. Oscillatory shear and steady-state shear measurements of Lin-nanocapsule emulsions were systematically investigated. The results of steady-state shear showed that Lin-nanocapsule emulsion, which was Newtonian only for high shear rate, was non-Newtonian. It was proved by oscillatory shear that when oscillation frequency changed from low to high, Lin-nanocapsules emulsion changed from viscous into elastic.

Abstract Flavors represent a small but significant segment of food industry. Sensory characteristics play an important role in the process of consumer acceptance and preference. Indocalamus leaf takes on a pleasant odor and indocalamus leaf flavor can be used in many products. However, indocalamus leaf flavor formula has not been reported. Therefore, developing an indocalamus leaf flavor is of significant interests. Note is a distinct flavor or odor characteristic. This paper concentrates on preparation and creation of indocalamus leaf flavor according to the notes of indocalamus leaf. The notes were obtained by smelling indocalamus leaf, and the results showed that the notes of indocalamus leaf flavor can be classified as: green-leafy note, sweet note, beany note, aldehydic note, waxy note, woody note, roast note, creamy note, and nutty note. According to the notes of indocalamus leaf odor, a typical indocalamus leaf flavor formula was obtained. The indocalamus leaf flavor blended is pleasant, harmonious, and has characteristics of indocalamus leaf odor.
