Umur Simpan Sekunder Krimer Kental Manis dengan Variasi Kondisi dan Suhu Penyimpanan

Abstract

Krimer kental manis merupakan produk olahan susu yang berpotensi mengalami penurunan mutu setelah kemasan dibuka. Penelitian ini bertujuan menganalisis pengaruh suhu dan kondisi penyimpanan terhadap mutu mikrobiologi, fisikokimia, dan sensori serta menentukan umur simpan sekundernya. Data dianalisis menggunakan Analysis of Variance (ANOVA) pada taraf signifikansi 5%. Hasil penelitian menunjukkan bahwa seluruh perlakuan masih memenuhi persyaratan mutu mikrobiologi hingga hari ke-14 penyimpanan. Nilai ALT dan AKK tidak dipengaruhi secara signifikan oleh suhu, kondisi penyimpanan, maupun lama penyimpanan (p>0,05). Nilai pH dipengaruhi oleh kondisi penyimpanan dan lama penyimpanan, sedangkan nilai aktivitas air (aw) dipengaruhi oleh suhu penyimpanan dan lama penyimpanan (p<0,05). Skor sensori dipengaruhi oleh interaksi antara suhu dan kondisi penyimpanan (p<0,05). Seluruh perlakuan masih memenuhi batas penerimaan sensori hingga hari ke-14 sehingga krimer kental manis kemasan kaleng memiliki umur simpan sekunder sekurang-kurangnya 14 hari setelah kemasan dibuka.

Sweetened condensed creamer is susceptible to quality deterioration after opening. This study aimed to evaluate the effects of storage temperature and conditions on microbiological, physicochemical, and sensory quality and to determine its secondary shelf life. Data were analyzed using Analysis of Variance (ANOVA) at a 5% significance level. The results showed that all treatments met microbiological quality requirements up to 14 days of storage. Total Plate Count (TPC) and Yeast and Mold Count (YMC) were not significantly affected by storage temperature, storage condition, or storage duration (p>0.05). The pH value was significantly affected by storage condition and storage duration, while water activity (aw) was significantly affected by storage temperature and storage duration (p<0.05). Sensory scores were influenced by the interaction between temperature and storage conditions (p<0.05). All treatments remained within the sensory acceptance criteria up to 14 days of storage. Based on these findings, canned sweetened condensed creamer had a secondary shelf life of at least 14 days after opening.
