Abstract

Yoghurt is a dairy product that is fermented using one or more bacteria called a starter. This study aims to determine the potential of indigenous bacteria Lactobacillus plantarum Dad-13 as a starter in the production of yoghurt functional. The method in this research is a literature study that comes from Google Scholar, Science Direct, Pubmed dan Research Gate. The selection of cited journals has gone through a screening process based on inclusion, special and exclusion criteria. Generally, the bacteria were used as starters in yoghurt production are Lactobacillus bulgaricus and Streptococcus thermophilus. One of the indigenous bacteria from Indonesia that has a potential to be used as a starter is Lactobacillus plantarum Dad-13. Based on various previous studies, these bacteria are able to produce yoghurt products with good physicochemical and organoleptic properties. The use of Lactobacillus plantarum Dad-13 as a starter can increase the functional properties of the resulting yoghurt product. These bacteria are able to produce high levels of folate in yoghurt and one of probiotic bacteria that has been tested for its effectiveness and benefits for health. It is stated that yoghurt and probiotics are included in functional foods. Based on the literature review data that has been carried out, the use of these bacteria has the potential to produce yoghurt products with high functional properties and beneficial for health.

Abstract

Rumput laut atau ganggang laut yang lebih dikenal dengan nama lain alga merupakan komoditi ekspor yang sangat potensial untuk dikembangkan. Jenis alga yang bernilai ekonomis tinggi diantaranya Eucheuma cottonii, Eucheuma spinosum, Glacilaria sp, dan Gelidium sp. Antioksidan sangat bermanfaat bagi kesehatan karena dapat mencegah pemicu penyakit degeneratif seperti : kanker, jantung, katarak, diabetes, hati, penuaan dini dan antioksidan juga dapat mempertahankan mutu produk pangan. Alga hijau mengandung senyawa fenol yaitu senyawa fitokimia yang dapat bermanfaat bagi kesehatan salah satunya adalah sebagai antioksidan. Beberapa penelitian menunjukkan bahwa alga hijau jenis Caulerpa racemosa memiliki kandungan total fenol yang tinggi yaitu sebesar 2624,62 mg GAE/g dibandingkan jenis Caulerpa sp. lainnya, seperti pada Caulerpa lentillifera sebesar 42,85 mg GAE/g ekstrak. Sehingga dapat disimpulkan bahwa alga hijau yang mengandung senyawa fenol dapat dimanfaatkan sebagai sumber antioksidan alami. Hasil review ini diharapkan dapat digunakan sebagai rujukan pembaca untuk penelitian selanjutnya serta dapat mengetahui manfaat dan kandungan alga hijau jenis Caulerpa racemose.

Abstract

Salak (Salacca zalacca Var. Amboinensis) is widely spread in Indonesia. Processing salak using fermentation method can provide added value and extend the shelf life. Fermented salak product combined with kombucha from balck tea is expected to increase the product’s ability to inhibit free radicals and provide healthful effects for health, especially the digestive process. This research endeavors to assess the capacity and antioxidant activity (IC50) from the product. The data that has been obtained was analyzed statistically using a completely randomized two-factor design. The first factor involves the ratio of salak extract to black tea, featuring three levels 80:20 ; 70:30 ; 60:40. The second factor encompasesses varying fermentation duration with four levels 4,8,12, and 16 days fermentation. The experiment was replicated three times. The result is that the comparison of salak extract with black tea had an antioxidant capacity between 101,37-479,30 GAE/100g. The result for antioxidant activity (IC 50) between 97,77-179,61 ppm.
