“…For instance, snails produce mucin in abundance in their mucus secretion. The mucin also called slim contains a bactericidal glycoprotein known as ‘achacin’ [ 7 ]. Also, the use of snail mucin for wound healing has been reported [ 8 ].…”

BackgroundFood flavor appreciation is one of the first signals along with food appearance and texture encountered by consumers during eating of food. Also, it is well known that flavor can strongly influence consumer’s acceptability judgment. The increase in the consumption of snail meat across the world calls for the need to research into the aroma compounds responsible for the distinctive aroma notes of processed snail meat.ResultsThe odorants responsible for the unique aroma notes in thermally processed giant African snail meats were evaluated by means of aroma extract dilution analysis (AEDA), gas chromatography–olfactometry (GC–O) and odor activity values (OAVs) respectively. Results revealed significant differences in the aroma profiles of the raw and thermally processed snail meats. Whilst the aroma profile of the raw snail meat was dominated with the floral-like β-ionone and β-iso-methyl ionone, sweaty/cheesy-like butanoic acid, and the mushroom-like 1-octen-3-one, the boiled and fried samples were dominated with the thermally generated odorants like 2-methylpyrazine, 2,5-dimethylpyrazine, 2-acetylthiazole and 2-acetylpyridine.ConclusionFinally, results have shown that sotolon, 2-acetyl-1-pyrroline, 2-furanmethanethiol, 2-methylbutanal, 1-octen-3-one, octanal, furanone, 2-methoxyphenol, 2-acetylpyridine, 2-acetylthiazole, and 2-methylpyrazine contributed to the overall aroma of the thermally processed snail meat.

“…Snail slime has become a remarkable ingredient in cosmetic products because it contains some biochemical substances, which have properties useful to skin care, such as alantoin, elastin, collagen and hyaluronic acid [5] . Furthermore, the slime has also been reported to have pharmacological activities including antibacterial activity [6,7] , antioxidant and regenerative properties [8] and anticancer property [9] . Interestingly, the slime extracted from Achatina fulica has been reported to heal incised wounds faster than self-healing can [10] .…”

The present study aims to investigate the antiinflammatory activity of the slime extracts from the giant African snail, Lissachatina fulica. In this study, aqueous and ethanol extracts of the snail slime were evaluated for antiinflammatory activities in vitro. The aqueous extract showed greater antiinflammatory activities than the ethanol extract. The aqueous extract was further tested for antiinflammatory activity in vivo. For acute inflammation, the ear oedema assay was used to screen the slime extract. The results revealed that application of 2 mg/ear extract or phenylbutzone could significantly reduce oedema when compared with ethanol-treated ears. For chronic inflammatory test, the cotton pellet granuloma model was employed to determine the activity of the slime extract. It was found that 2.5 and 6.25 % extract could significantly reduce transudative and granuloma weights. Moreover, the extracts also reduced malondialdehyde and increased superoxide dismutase in the granuloma tissue of the induced rats. In conclusion, the slime extract showed antiinflammatory activity both in vitro and in vivo. The antiinflammatory activity was also observed against acute and chronic inflammations, which suggested that the slime extracts has the potential to be developed into antiinflammatory products.

“…This might re ect the strong antibacterial activity of L. fulica mantle mucus against all four tested bacteria, while the mucus from the foot that lacked this protein band could inhibit only the growth of E. coli and S. aureus. Previous studies have reported that the mucus from L. fulica and H. aspersa exhibited antibacterial activity against various strains of bacteria and fungi [26][27][28][29][30]. Moreover, several antimicrobial peptides (AMPs) from L. fulica mucus and H. aspersa have been investigated [25,[31][32][33][34].…”

Objective: Snails secrete different types of mucus that serve several functions, and are increasingly being exploited for medical and cosmetic applications. In this study, we explored the protein pattern and compared the biological properties of the mucus secreted from the mantle collar and foot of two snail species, Lissachatina fulica and Hemiplecta distincta.Result: Protein profile showed a different pattern between the two species and between the two secretory parts. The mantle-specific protein bands were further characterized and among them was an antibacterial protein, achacin. Accordingly, the mucus from the mantle exhibited the higher antibacterial activity than that from the foot in both snail species. The mucus from H. distincta, first reported here, also showed antibacterial properties, but with a lower activity compared to that for L. fulica. Snail mucus also exhibited anti-tyrosinase activity and antioxidant activity but with no significant difference between the foot and mantle mucus. These results indicate some different protein compositions and biological activities of snail slime from the mantle and foot, which might be associated with their specific functions in the animal and are useful for medical applications.
