Rahayu, Vina Agustin Eka and Dr.Ir. Sandra Malin Sutan,, MP and Joko Prasetyo,, STP., M.Si (2021) Pengaruh Perlakuan Pre-cooling dan Kemasan Perforasi terhadap Buah Pepaya (Carica papaya L.) Fresh-cut yang Disimpan pada Suhu Rendah. Sarjana thesis, Universitas Brawijaya.
Abstract
Pepaya merupakan buah yang banyak digemari dan dikonsumsi oleh masyarakat. Perubahan kebutuhan masyarakat menyebabkan buah pepaya diolah dalam bentuk fresh- cut, namun produk ini memiliki kelemahan yaitu lebih tidak tahan lama dibandingkan buah utuh sebagai akibat perlakuan pengupasan, pemotongan, pengirisan yang menyebabkan jaringan pada buah terluka. Teknik penanganan produk dibutuhkan untuk mempertahankan produk pada kondisi paling optimum salah satunya dengan teknik pendinginan awal dan pengemasan yang tepat. Perlakuan pendinginan pendahuluan (pre- cooling) dengan penggunaan ice gel sebagai bahan pendingin diberikan untuk menekan panas lapang dari produk, serta pemberian lubang pada kemasan diaplikasikan agar proses pertukaran O2 dan CO2 dapat berlangsung dengan baik. Penelitian ini bertujuan untuk menganalisa pengaruh pre-cooling dan jumlah perforasi kemasan terhadap susut bobot, total padatan terlarut, serta tingkat kesukaan panelis terhadap warna, tekstur dan rasa buah pepaya fresh-cut yang disimpan pada suhu rendah. Penelitian ini menggunakan metode Rancangan Acak Lengkap (RAL) faktorial yang terdiri dari 2 faktor yaitu pre-cooling dan kemasan perforasi, dengan pengulangan sebanyak 3 kali. Pengujian terhadap parameter yang diukur dilakukan setiap dua hari sekali kemudian data hasil pengamatan diolah menggunakan ANOVA dengan taraf signifikasi 5%. Dari pengolahan data didapatkan adanya pengaruh perlakuan pre-cooling terhadap tingkat kesukaan panelis pada tekstur dan rasa, serta pengaruh perlakuan kemasan perforasi terhadap susut bobot, dan tingkat kesukaan panelis pada tekstur dan rasa. Indeks L*a pada buah pepaya fresh-cut nilainya menurun selama penyimpanan pada suhu rendah.
English Abstract
Papaya is a fruit that is much favorite and consumed by the community. Changes in people's needs cause papaya fruit to be processed in fresh-cut form. Changes in people's needs cause papaya fruit to be processed in the form of fresh-cut, but this product has a weakness that is less durable than whole fruit as a result of peeling, cutting, slicing treatment which causes the tissue in the fruit to be injured. Product handling techniques are needed to maintain the product in the most optimum condition, one of which is pre-cooling and proper packaging techniques. Pre-cooling treatment with the use of ice gel as a cooling agent is given to suppress the field heat of the product, and holes in the packaging are applied so that the O2 and CO2 exchange process can take place properly. This study has a goal to analyze the effect of pre-cooling and the number of packaging perforations on weight loss, total dissolved solids, and the panelists' preference for color, texture and taste of fresh-cut papaya stored at low temperatures. This study used a factorial Completely Randomized Design (CRD) method consisting of 2 factors, namely pre-cooling and perforated packaging, with 3 repetitions. Tests on the measured parameters were carried out every two days and then the observed data were processed using ANOVA with a significance level of 5%. From the data processing, it was found that there was an effect of pre-cooling treatment on the panelist's preference level on texture and taste, as well as the effect of perforated packaging treatment on weight loss, and the panelist's preference level on texture and taste. The L*a index of fresh-cut papaya fruit decreased during storage at low temperatures.
