Abstract

Macaron adalah kue sederhana yang biasanya terbuat dari putih telur, gula, dan tepung almond, dimana dua buah macaron ditengahnya diberikan isian. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan pewarna dari buah naga, labu kuning, dan daun suji sebagai pewarna alami terhadap mutu fisik macaron oat.  Metode analisis data yang digunakan yaitu metode RAL (Rancang Acak Lengkap), dengan 3 perlakuan pewarna alami yaitu pewarna dari buah naga, labu kuning dan daun suji. Berdasarkan hasil penelitian,  kadar air tertinggi yaitu penggunaan pewarna alami dari buah naga sebesar 15,68% sedangkan kadar air terendah yaitu kontrol sebesar 6,18%. Hasil sensoris yang paling disukai panelis pada uji hedonik yaitu parameter warna sampel daun suji. Uji deskriptif terbaik yaitu parameter rasa manis sampel kontrol.

Abstract

The limited shelf life of red guava fruit encourages efforts to maintain its shelf life by using the sealing and wrapping packaging method with storage at 9ºC for 12 days. The purpose of this study was to determine the effect of packaging method and storage time on the chemical properties of red guava (Psidium guajava L.). This study used a factorial design consisting of 2 factors. The first factor is the packaging method (without packaging, sealing and wrapping). The second factor is storage time (day 0, day 3, day 6, day 9 and day 12). The results showed that the highest vitamin C content was in the sealing packaging method, namely on the 3rd day of storage at 3.3%. the highest water content value is 90.45% on the packaging method of wrapping storage on day 0, the highest value of total titrated acid in fruit with packaging method of packaging storage day 0 is 0.08%, while the highest value of total dissolved solids was 7.33oBrix on the 12th day storage sealing packaging method.
