Abstract

ABSTRACT

Pineapple skin (Ananas comosus L.) has good nutritional value. Pineapple waste that has not been used will cause environmental problems, and therefore one of the utilization of pineapple waste by fermentation. The addition of benzoic acid is done so that the fermentation product is not alcoholic. The aim of this study was to evaluated the effect of addition benzoic acid on yeast growth and alcohol content on the fermentation of pineapple skin (Ananas comosus L.). Fermentation was carried out for 7 days by adding some concentrations of benzoic acid and measured total acid, alcohol content, pH, and yeast growth on media Saboroud Dextrose Agar (SDA). Results of the study showed that the added fermentation concentration of 0.05%; 0.1% and 0.2% benzoic acid have lower alcohol content and yeast amount compared with fermentation using 0% benzoic acid, so concluded there is an effect of the addition of benzoic acid on yeast growth and alcohol content.

ABSTRAK

Kulit buah nanas (Ananas comosus L.) memiliki nilai gizi yang baik. Limbah buah nanas yang belum dimanfaatkan akan menimbulkan masalah lingkungan, maka dari itu salah satu pemanfaatan limbah buah nanas dengan cara fermentasi. Penambahan asam benzoat dilakukan agar produk fermentasi tidak bersifat alkoholik. Penelitian ini bertujuan mengevaluasi pengaruh penambahan asam benzoat terhadap kadar alkohol dan pertumbuhan ragi pada fermentasi kulit nanas (Ananas comosus L.). Fermentasi dilakukan selama 7 hari dengan menambahkan beberapa konsentrasi asam benzoat kemudian diukur total asam, kadar alkohol, pH, serta pertumbuhan ragi pada media Saboroud Dextrose Agar (SDA). Hasil penelitian menunjukan bahwa fermentasi yang ditambahkan konsentrasi 0,05%; 0,1% dan 0,2% asam benzoat memiliki kadar alkohol dan jumlah ragi yang lebih rendah dibandingkan dengan fermentasi yang menggunakan 0% asam benzoat, sehingga disimpulkan terdapat pengaruh penambahan beberapa konsentrasi asam benzoat terhadap pertumbuhan ragi dan kadar alkohol.
