Nutrient content and shelf life analysis of freshwater snail (Pila ampullacea) instant baby porridge

Abstract

The quality of instant baby porridge leads to nutrient content, consumer’s acceptability and shelf life. The use of freshwater snail flour (Pila ampullacea) as a substitution in the product increases the product nutrition value. The study analyzed nutrients content, acceptability, and shelf life of instant baby porridge. An experimental study with a completely randomized single factor design by using the three ratios of freshwater snail flour KS 0 (0%), KS I (10%), and KS II (15%). The acceptability test (hedonic test) was held on 25 semi-trained panelists and Arrhenius for shelf life analysis. Data were analyzed using One-way ANOVA, Krusskal wallis test, and Mann-Whitney. The substitution of freshwater snail flour could affect the nutrient content of carbohydrate, protein, fat, fiber, water, ash, iron, zinc, and calcium (p<0.05). The substitution could affect the consumer’s acceptance properties include color, flavor, texture, and taste (p<0.05). The shelf-life testing for 15 days obtained results, KS 0 formula in temperature 35oC, 45oC and 50oC is 7.13; 2.13 and 2.16 months respectively. KS I Formula in temperature 35oC, 45oC and 50oC is 39, 40, 41 days. KS II Formula in temperature 35oC, 45oC and 50oC is 6 years 7 months, 6 years 8 months, and 6 years 9 months. Based on nutrient content analysis, the substitution of freshwater snail flour could have enhanced protein, zinc, iron, calcium, and fat. KS I, the best formula obtained has 20 g contribution in one serving, fulfilled the energy adequacy of 14.41%, carbohydrates, 15.36%, protein 17.7%, fat 10.27%, fiber 1.7%, water 0.16%, iron 11.25%, zinc 10%, calcium 35.10% and the shelf life in temperature of 35oC is 39 days, 45oC has a shelf life of 40 days and 50oC has a shelf life of 41 days.
