The invention relates to a
processing technology of quick-frozen sweet potato strips. The
processing technology comprises the following steps of harvesting sweet potatoes, performing saccharificationtreatment, performing cleaning, performing peeling, performing trimming, performing
cutting to obtain sweet potato strips, performing soaking, performing cooking, performing baking, performing quick-freezing, performing
ultraviolet sterilizing, performing
vacuum packing and performing warehousing. The sweet potato strips made by the
processing technology are soft in texture, have certain tenacity,are uniform in color, glossy and red, unique in mouth feel, and pure in
flavor, maintain
primary color of the sweet potatoes, maintain the fragrance and the
flavor of the sweet potatoes, and are highin yield.
Hygiene and safety are guaranteed, the quick-frozen sweet potato strips are free from any good additive, short in processing time, and low in loss of
nutrient components; the quality guarantee period of the quick-frozen sweet potato strips at normal temperature is 9 months, and the quality guarantee period of the quick-frozen sweet potato strips under the
refrigeration condition is 14 months. The quick-frozen sweet potato strips conform to the
quality standard that the
total bacterial count is smaller than or equal to 1000CFU / g, mould is smaller than or equal to 50CFU / g, the
escherichia coli is smaller than or equal to 30MPN / 100g,
pathogenic bacteria are not detected, and the
nutrient and the
flavor of the sweet potatoes can be improved, so that the requirements of consumers canbe met.
