Micro-encapsulated strawberry fragrance was successfully prepared with wall materials including maltodextrin, sodium octenylsuccinate and gum Arabic. The micro-capsule was added to wallpaper and aromatic wallpaper with strawberry characteristics was obtained. The particle distribution, surface morphology, chemical structure, thermal property and controlled release performance of micro-encapsulated fragrance and aromatic wallpaper were investigated using laser particle size analyzer, scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-TR), thermal gravity analysis (TGA) and chromatography-mass spectrometer (GC-MS). The results showed that the average diameter of micro-capsule was 2 μm and the particles mainly distributed in the tissues of wallpaper. The result of TGA showed that the micro-capsule had a good stability. Meanwhile, the aromatic wallpaper had strawberry aroma more than 3 months and took on excellent controlled release performance.

Aim/purpose - Olfactory marketing is a phenomenon that is in the current trend of usage by marketing experts to ensure that consumers are more involved in the purchase decision-making process. This paper aims to review the studies involved in consumer purchase intentions influenced by fragrance and develop a framework for modeling consumer responses. Design/methodology/approach - PRISMA technique was used as a methodological approach. First, the researchers made criteria for inclusion and exclusion of studies along with the application of a set of keyword research strings to identify the relevant research articles. Second, prominent scientific search databases like EBSCO Host, Scopus, and ScienceDirect were used to mainly search the relevant literature. Findings - This article advances knowledge on the topic of fragrance marketing and proposes an integrative framework of consumer purchase responses considering the mutual relationship shared between fragrance, the influence of control variables, and response outcomes focusing on cognitive responses, intentions and behavior. The results of the conducted review also suggest that retail consumers tend to develop a positive attitude and behavior towards the place where the product and service are being sold. Research implications/limitations - The paper would be particularly helpful for managers in designing the right strategy for creating loyalty for their retail outlets and thereby creating a niche for themselves. Originality/value/contribution - The study assists marketers in understanding the impact of olfactory marketing in increasing short-term and long-term retail sales and determines future research directions to enrich the existence of these theories to fathom the essence behind consumers' interpretations of olfaction in retail outlets.

Oximes of 4-(furan-2-yl)butan-2-one, 4-(furan-3-yl)butan-2-one, 4-(5-methylfuran-2-yl)butan-2-one, 4-(thiophen-2-yl)butan-2-one, 4-(5-methylthiophen-2-yl)butan-2-one and 4-(3-methyl-thiophen-2-yl)butan-2-one have been synthesized. The sensory analysis revealed interesting and complex properties of methyl furan derivative: green, weed-like, similar to herb and flower of nettle. Replacement of oxygen atom by sulfur one in the aromatic ring resulted in creation of smell associated with food.

W artykule opisano syntezę, charakterystykę spektralną oraz zapachową oksymów 4-(furan-2-ylo)butan-2-onu, 4-(furan-3-ylo)butan-2-onu, 4-(5-metylofuran-2-ylo) butan-2-onu, 4-(tiofen-2-ylo)butan-2-onu, 4-(5-metylotiofen-2-ylo)butan-2-onu oraz 4-(3-metylotiofen-2-ylo)butan-2-onu. Pochodne metylofuranowe okazały się interesujące pod względem zapachowym. Ich zapach można opisać jako: zielony, podobny do ziela i kwiatu pokrzywy. Zastąpienie atomu tlenu, atomem siarki w pierścieniu aromatycznym skutkowało otrzymaniem związków charakteryzujących się zapachem związanym z żywnością.

Floral epidermal cells of most species of Bulbophyllum Thouars studied to date produce both lipid-rich foodrewards and fragrance. Since fragrances largely consist of terpenoids and have an affinity for lipophilic stains, the simultaneous presence of lipid-rich food-rewards frustrates identification of fragrance-secreting cells by conventional histochemistry. Furthermore, since both lipid-rich food-rewards and fragrances are probably synthesized by a similar complement of organelles, interpretation of TEM images can prove difficult. All members of section Racemosae Benth. & Hook. f. investigated to date, however, are unusual in their secretion of a predominantly proteinaceous food-reward, and lipids are seemingly absent. This might enable their use as models for the identification and characterization of fragrance-secreting tissues and organelles. Three members of sect. Racemosae were chosen, namely Bulbophyllum dissitiflorum Seidenf., B. lilacinum Ridl. and B. tricorne Seidenf. & Smitinand. All produced food-rewards. Of these, one (B. dissitiflorum) lacked fragrance and was used as a control, whereas the remaining two species produced fragrance. Having established that the food-reward was mainly proteinaceous in each case, and did not test positively for lipid, we undertook further histochemical investigations, as well as light microscopy, SEM and TEM. Specialized palisade-like epidermal cells of all species contained protein bodies and rough endoplasmic reticulum consistent with the production and secretion of a protein-rich food-reward. Cuticular pores were also present. In fragrant species, these cells also contained abundant smooth endoplasmic reticulum, oil droplets and many, well-developed, spherical plastids with numerous plastoglobuli, similar to those found in the osmophores (fragrance-producing structures) of other orchids. Indeterminate, osmiophilic cytoplasmic inclusions were also present. By contrast, the non-fragrant species lacked oil droplets and other osmiophilic inclusions and the plastids were scant, poorly developed, often elongate or irregular in shape and contained few plastoglobuli. Smooth endoplasmic reticulum was also less frequent. Since food-rewards tested negatively for lipid, it is probable that any oil droplets present were involved in fragrance production, especially since they were absent from the non-fragrant species. Thus, the unusual absence of lipids from the food-rewards of sect. Racemosae provided a rare opportunity, permitting, for the first time, the unraveling of these two secretory processes (food-reward and fragrance) in Bulbophyllum and clearly demonstrating the plasticity of these cells and their dual role in secretion.

The purpose of this article is to determine the function of one of the minor literary motifs present in the Roman literature of the Augustan period, i.e., the motif of the perfumed and wealthy Arab and fragrant and rich Arabia. This goal is achieved here in two steps: first, the appropriate source material is compiled, and then the material is analysed and the conclusions are formulated. The source material in this case is seventeen extracts from Virgil, Horace, Tibullus, Pseudo-Tibullus, Propercius and Ovid. These fragments were divided into those, in which the respective fragrance motif was embedded in the axiological context (sixteen fragments), and those, in which the motif appears in the neutral context (one fragment). Among the first there were separated those, in which the positive axiological context is dealt with (ten fragments), and those, in which the negative axiological context is dealt with (six fragments). The fragments of the first type mention the value of a woman (four fragments), religious activities (three fragments), the Roman land (two fragments) and peace (one fragment), while the fragments of the second type express the worthlessness of wealth (five fragments) and remoteness from the loved person (one fragment). In turn, the analysis was carried out in two steps. First, it was found that Latin poets and writers of the Augustan period use the fragrance motif when they value, whether positively or negatively, people or things or situations, or activities, and that these writers use the motif discussed here to build images that appeal to the public. Secondly, it was established that the Arabic motif is expressed at the same time in a lot of different words, should all the fragments in which it appears, be taken together, and in few words, should each of the fragments should be considered separately.
