Embodiment 1

[0021] Fresh lotus roots with pure taste, no peculiar smell, no pests, and no rot are taken, and the terminal lotus roots do not exceed 20%. Rinse the lotus root with water, cut off the joints and then scrub in clean water until the surface of the lotus root has no rust color, and then put it in a citric acid solution with a mass content of 0.1% for cleaning; send the cleaned lotus root to a crusher for crushing, and crush it at the same time Add purified water according to the lotus root: purified water mass ratio of 1:0.8, and then process it with a colloid mill to obtain thick lotus root pulp. Add citric acid to the thick lotus root pulp while glue grinding, and add citric acid according to 0.1% of the mass of lotus root after cleaning. The thick lotus root slurry after the rubber mill is separated from the lotus root residue and the lotus root pulp with a continuous separator, and the lotus root residue is pressed again, and the lotus root slurry obtained by pressing is mer...

Embodiment 2

[0023] Fresh lotus roots with pure taste, no peculiar smell, no pests, and no rot are taken, and the terminal lotus roots do not exceed 20%. Rinse the lotus root with water, cut off the joints and then scrub in clean water until the surface of the lotus root is rust-free, then put it in a citric acid solution with a mass content of 0.2% for cleaning; send the cleaned lotus root to a crusher for crushing, and crush it while crushing. Add purified water according to lotus root: purified water mass ratio 1: 0.9, then process with colloid mill to obtain thick lotus root slurry, add citric acid to the thick lotus root slurry while gluing, citric acid is added by 0.07% of the lotus root mass after cleaning The thick lotus root slurry after the rubber mill is separated from the lotus root residue and the lotus root pulp by a continuous separator, and the lotus root residue is pressed again, and the lotus root slurry obtained by pressing is combined with the lotus root slurry obtained ...

Abstract

The invention relates to a processing method for a PET bottling clarifying lotus root juice series drink, belonging to the technical field of food processing. The method takes fresh lotus root as raw material and produces the novel PET bottling clarifying lotus root juice series drink by carrying out the steps of nodus removal and washing, crushing, glue-grinding, slurry and dreg separation, zymohydrolysis, clarification, separation, filtration, preparation, homogenization, degasification, sterilization, hot filling, sealing, bottle falling, cooling and inspection, and utilizing modern biotechnology, color protecting technology and conserving technology. The lotus root juice drink produced by the method of the invention has full-bodied lotus root flavor due to clarification, can be conserved at normal temperature, is convenient to be drunk and adopts one-time sterilizing hot filling with low sterilization strength, thus having less damages to the nutrient content of the products.

Description

technical field [0001] The invention relates to a processing method for PET bottled clarified lotus root juice series beverages, belonging to the technical field of food processing. Background technique [0002] Lotus root (Nelumbo nucifera Gaertn) is a perennial aquatic plant of Nymphaeaceae. Lotus root is rich in nutrition. According to the measurement, every 100g of lotus root contains 10-20g of starch, 1-2g of protein, 25-55mg of VC, and also contains calcium, phosphorus, iron and other mineral elements. Since ancient times, lotus root has been a kind of aquatic vegetable loved by our people. In recent years, with the development of the food industry, the research on lotus root processing has gradually increased. The lotus root juice beverage is popular among consumers for its convenience and novel form. Domestic researchers have done a lot of research on lotus root juice beverage processing, mainly focusing on lotus root juice extraction, color protection and precipita...
