          Abstract

          Prevalensi angka hipertensi di Indonesia cukup tinggi 31,4% yang disebabkan oleh beberapa faktor salah satunya tingkat konsumsi garam berlebihan. Diet garam atau mengonsumsi garam rendah natrium merupakan alternatif untuk mengurangi kasus hipertensi. Garam diet dapat diproduksi dengan beberapa metode salah satunya metode fortifikasi. Kerang pisau memiliki kandungan gizi tinggi khususnya kandungan protein, oleh karena itu baik digunakan sebagai bahan pembuatan garam fortifikasi. Tujuan penelitian ini adalah menentukan konsentrasi garam kasar dan tepung kerang pisau terbaik dalam pembuatan garam fortifikasi berdasarkan karakteristik sensori dan mikroba. Perlakuan yang digunakan meliputi garam kasar yang dihaluskan dan tepung kerang pisau. Perbandingan konsentrasi garam (%) dan tepung kerang pisau (%) yaitu 95:5 (F1), 90:10 (F2), 85:15 (F3), 80:20 (F4), 75:25 (F5), dan 50:50 (F6). Parameter kimia yang diamati, yaitu NaCl, kadar air, protein, abu, lemak, dan karbohidrat. Parameter mikroba yang diamati, yaitu bakteri Escherichia coli. Parameter sensori yang diamati meliputi tekstur, warna, aroma, dan rasa. Hasil uji organoleptik menunjukkan bahwa perlakuan F6 (50:50%) terbaik dengan nilai tekstur 7,2 (suka); aroma 6,53 (netral); warna 7,2 (suka); dan rasa 7,93 (suka) dari skala 1-9. Karakteristik kimia garam fortifikasi perlakuan terbaik (F6), yaitu NaCl 52,52%, kadar air 6,61%, protein 42,11%, abu 46,6%, lemak 0,98%, dan karbohidrat 3,7%.  Kelimpahan bakteri E. coli pada seluruh produk yaitu <3 MPN/g. Perlakuan F6 (50%:50%) dapat direkomendasikan sebagai perlakuan terbaik berdasarkan hasil pengujian parameter mikroba dan sensori.

          Effect of Salt Reduction on Consumer Acceptance and Sensory Quality of Food

          Reducing salt (NaCl) intake is an important public health target. The food industry and catering services are searching for means to reduce the salt content in their products. This review focuses on options for salt reduction in foods and the sensory evaluation of salt-reduced foods. Simple salt reduction, mineral salts and flavor enhancers/modifiers (e.g., umami compounds) are common options for salt reduction. In addition, the modification of food texture and odor-taste interactions may contribute to enhanced salty taste perception. Maintaining consumer acceptance of the products is a challenge, and recent examples of the consumer perception of salt-reduced foods are presented.

              Comparison of dry- and wet-heat induced changes in physicochemical properties of whey protein in absence or presence of inulin

              Changes in whey protein (10%, w/v) induced by dry-heating (60 °C for 5 days at a relative humidity of 63%), wet-heating (85 °C for 30 min) or the two-combined heating in absence or presence of inulin (8%, w/v) were studied. Mixture of whey protein and inulin showed significantly higher absorbance at 290 nm than whey protein alone in all heating conditions while only dry-heated samples showed significantly increased absorbance value at 420 nm ( p  < 0.05). Whey protein after heating showed significantly lower zeta potential and inulin decreased the value of all heated samples further ( p  < 0.05) except for samples after dry-heating. Heating decreased the free sulfhydryl group content of whey protein samples while presence of inulin decreased further ( p  < 0.05). Dry-heating decreased while wet-heating increased the surface hydrophobicity of whey protein. Inulin had no effect on the surface hydrophobicity of heated whey protein under dry-heating but decreased under wet-heating.
