Vitamin dalam Makanan Vitamin larut air banyak yang hilang saat proses pemasakan. Kehilangan vitamin dalam pemasakan dapat dicegah dengan cara : • Suhu tdk terlalu tinggi • Waktu masak tdk terlalu lama • Menggunakan air pemasak sesedikit mungkin • Potongan bahan makanan tdk terlalu halus • Panci ditutup • Sisa air rebusan utk masakan lain
Vitamin Larut Air • Larut dalam air • Terdiri dari Vitamin C, vitamin B • Biasanya tdk disimpan dalam tubuh dan dikeluarkan melalui urin dalam jumlah kecil • Banyak hilang dalam proses pemasakan • Membantu dlm metabolisme energi
Water-soluble vitamins dissolve in water. Because water-soluble vitamins are not stored by the body to any extent, foods reach in these vitamins must be eaten more often than foods with fat-soluble vitamins. • Fruits and vegetables are good source of water soluble vitamins.
VITAMIN C • Common Food Sources : • Citrus fruits, berries, tomatoes, broccoli, melon, potatoes, green peppers, green and yellow vegetables • Major Body Functions : • Aids in the formation of collagen • Aids in the absorption of iron into the body • Prevents oxidation • Wound healing • Maintaining blood vessels, bones, teeth • Production of brain hormones • Immune factors
