Abstract

Barlin banana contain high nutrients but are not widely processed. Barlin banana velva with the addition of katuk leaf extract will produce a frozen dessert product that is high in nutrition. The addition of CMC (carboxy methyl cellulose) is expected to improve the physicochemical properties of the Velva. This research aimed to determine the effect of katuk leaf extract addition and CMC concentration on the physical, chemical, and organoleptic characteristics of barlin banana velva. This research used a Completely Randomized Design factorial pattern of two factors. Factor I was the addition of katuk leaf extract (2%, 4%, and 6%) and factor II was the concentration of CMC (0.5%, 0.6%, and 0.7 %). The data obtained was then analyzed using analysis of variance, if there were differences, it was continued with the Duncan test (DMRT). The results showed that the best treatment was on the addition of katuk leaf extract 6% and the concentration of CMC 0.5 % which produced barlin banana velva with water content of 70.76%, total solids 29.21%, antioxidant activity 29.15%, total phenols 1.007 mg TAE/g, vitamin C 35.49 mg/100gr, overrun 19.76%, melting time 19.33 minutes, and viscosity 2.16 Pa.s, hedonic organoleptic tests include taste 3.241 (liked a bit), aroma 3.068 (liked a little), texture 3.860 (like), and color 3.724 (like).

Abstract

Bumbu rasa sapi “Halawa” merupakan produk pangan berbentuk serbuk yang bersifat higroskopis dan rentan mengalami penurunan mutu akibat penyerapan uap air. Penelitian ini bertujuan untuk menduga umur simpan bumbu “Halawa” dengan pendekatan kadar air kritis melalui metode Accelerated Shelf-Life Testing (ASLT) pada tiga jenis kemasan: aluminium foil, metalized plastic, dan polipropilen. Penentuan umur simpan dilakukan dengan mengukur kadar air awal, kadar air kritis (berdasarkan uji sensori dengan 25 panelis semi-terlatih), dan kadar air kesetimbangan melalui paparan pada berbagai kondisi kelembaban relatif (RH) yang diatur menggunakan larutan garam jenuh. Data kadar air kesetimbangan kemudian dianalisis untuk membentuk kurva sorpsi isotermis dan ditentukan model terbaik melalui pendekatan matematis (Caurie, Halsey, Oswin, GAB, dll.) berdasarkan nilai Mean Relative Deviation (MRD). Nilai kemiringan kurva (b) dari model terpilih digunakan dalam perhitungan umur simpan. Parameter lain yang dihitung meliputi luas permukaan kemasan, bobot padatan per kemasan, serta permeabilitas uap air bahan kemasan berdasarkan metode ASTM D1249-90. Seluruh parameter kemudian disubstitusikan ke dalam persamaan Labuza untuk memprediksi waktu pencapaian kadar air kritis pada masing-masing jenis kemasan. Hasil menunjukkan kadar air awal sebesar 0,0066 gH₂O/g solid dan kadar air kritis sebesar 0,0636 gH₂O/g solid. Model sorpsi isotermis Hasley dipilih dengan persamaan Log(Ln(1/Aw)) = -1.3435 - 0.6872 log Me. Nilai permeabilitas masing-masing kemasan adalah 0,065; 0,214; dan 0,4 gH₂O/hari·m²·mmHg. Umur simpan tertinggi terdapat pada kemasan aluminium foil (1100 hari), diikuti metalized plastic (334 hari), dan polipropilen (178 hari). Kemasan terbaik untuk menjaga mutu bumbu “Halawa” adalah aluminium foil.
