“…Researchers confirm that the snail meat contains very high level and quality protein [17]. The data confirm that the protein content found in H. aspersa maxima meat was 12% in fresh mass [18], 16,3% in fresh mass [12] and 14.8-18.4% in dry mass [10]. In our study the high content of eggs protein was noticeable.…”

“…Also in Poland, the area of snail farm increases. Although the production of good quality snails is favorable a little is known about nutritional exigency [10]. And still the research on snail cultures Helix aspersa maxima is rare, despite that these are species with high economic value and a luxury food.…”

“…The content of cholesterol was higher for the sample obtained in May (sample 2) and March (sample 3) than for eggs obtained in March and stored only in +4ºC. Moreover in human nutrition dietary lipids are indicated as important, also health professionals recommend low cholesterol, low energy and low SFA (saturated fatty acid) diets [10]. According to Murphy [5] snail meat contains little fat.…”

This paper describes selected biochemical and analytical composition of Helix aspersa maxima eggs. Analyses determined the percentages of proteins, lipids, sugars, the composition of water and mineral elements, also antioxidant capacity. H. aspersa maxima eggs contain the high percentage of protein and are low in lipids (cholesterol content average 0.69 mg%), and are also found rich in Ca. The results showed that the eggs possess antioxidant activity and do not lose the antioxidants during short term storage in salt solution. The results make it possible to evaluate nutritional quality of eggs land snails as a good food source.

“…Komposisi proksimat daging keong kowoe dapat digolongkan sebagai hasil perikanan yang berprotein tinggi (38,06%) dan tinggi karbohidrat (10,66%) serta lemak rendah (dibawah 5%) sehingga baik untuk dikonsumsi khususnya bagi penderita penyakit hati (Milinsk et al 2006). Kandungan gizi keong kowoe setara dengan beberapa jenis moluska maupun echinodermata yang telah dikonsumsi dan secara empiris dipercaya sebagai aprodisiaka serta mampu mengobati berbagai penyakit (Witjaksono 2005dan Nurjanah et al 2005.…”

AbstrakKeong mas atau dalam bahasa daerah Sulawesi (Kabupaten Konawe) disebut sebagai "Keong kowoe" banyak dimanfaatkan masyarakat sebagai makanan. Keong ini dipercaya memiliki banyak khasiat dan manfaat, antara lain kandungan antioksidan yang tinggi. Penelitian ini bertujuan menentukan pelarut yang terbaik untuk mengekstrak komponen bioaktif keong mas dan menentukan kandungan antioksidannya. Penelitian ini meliputi analisis proksimat, uji kuantitatif aktivitas antioksidan dengan metode DPPH. Hasil pengukuran morfometrik menunjukkan rendemen daging sebesar 11,86%. Kandungan proksimat daging segar tertinggi pada kadar air sebesar 65,79%, protein 18,14%, abu 10,49%, karbohidrat 4,14% dan lemak 3,44%, sedangkan pada daging kering kadar air sebesar 40,04%, protein 38,06%, karbohidrat 10,66%, abu 8,53% dan lemak 2,70%. Hasil pengamatan didapatkan rendemen hasil ekstraksi senyawa aktif menggunakan pelarut kloroform (non polar) sebesar 1,78%, etil asetat (semi polar) 3,41% dan metanol 6,63% (polar). Rendemen yang tinggi pada pelarut metanol diduga karena keong kowoe mengandung lebih banyak senyawa aktif yang bersifat polar. Hasil uji aktivitas antioksidan ekstrak kasar jenis pelarut metanol (polar) mempumyai nilai IC 50 yaitu 111,28 ppm, sehingga tergolong sedang.Kata kunci: antioksidan, bioaktif, proksimat, rendemen Abstract Gold snail is called "Kowoe" in Celebes Island. They are widely utilized by people as food. This snail also has many properties and benefits. The aims of this study were to determine the best solvent to extract the bioactive components of snails and measure the antioxidant activity. The proximate analysis was caried out, then quantitative test of antioxidant activity by DPPH method was measured. The results of morphometric measurements showed the meat yield 11.86%. The proximate analysis of fresh meat consisted of water content 65.79%, 18.14% protein, 10.49% ash, 4.14% carbohydrates, and fats 3.44%, while the moisture content of dried meat contained 40/ 04%, 38.06% protein, carbohydrates 10.66%, ash 8.53% and 2.70% fat, respectively. The yield of extraction of the active compound using chloroform (non-polar) was 1.78%, ethyl acetate (semi-polar) was 3.41% and 6.63% methanol (polar). The snails kowoe contain more the polar of active compounds. The antioxidant activity of crude extract in methanol solvent (polar) had IC 50 values 111.28 ppm (moderate).

Aquatic ecotoxicological risks associated with tetravalent metallic elements such as thorium (Th) are still poorly understood. Periphytic biofilm represents an important food source in aquatic environments; thus, such risks could severely affect nutrient and energy cycling in these ecosystems. The present study investigated the potential for Th to change the fatty acid composition of biofilm communities. Bioaccumulation of Th and fatty acids were measured after 4 wk to 2 exposure conditions: a control (C0) and Th exposure (C10). Some major fatty acids such as C16:1n-7 and docosahexaenoic acid C22:6n-3 differed significantly between control and C10 conditions. To determine if Th can be trophically transferred and to investigate the impacts of nutritional quality changes on primary consumers, common pond snails (Lymnaea sp.) were fed for 4 wk with control and Th-exposed biofilm. Thorium appeared to be trophically transferable to the grazers, although we cannot exclude that part of the Th accumulated by the snails may have been taken from the water through release from the biofilms. The composition of major fatty acids observed in the grazers was also significantly affected, notably by a decrease of total polyunsaturated fatty acids. These results indicate that very low Th concentrations can decrease the nutritional quality of organisms at the base of the food chain.
