Embodiment 1

[0021] Take fresh lotus roots with pure taste, no peculiar smell, no pests, and no rot, and the end lotus roots shall not exceed 20%. Rinse the lotus root with water, cut off the lotus root joints, and then scrub the lotus root surface in clean water until the surface of the lotus root is rust-free, and then put it in a citric acid solution with a mass content of 0.1% for cleaning; send the cleaned lotus root to the crusher for crushing Add the purified water while pressing the lotus root: purified water mass ratio 1:0.8, and then use the colloid mill to obtain the crude lotus root pulp, and add citric acid to the crude lotus root pulp while grinding, and add the citric acid at 0.1% of the washed lotus root mass ; The coarse lotus root pulp after rubber grinding is separated by a continuous separator, and then the lotus root pulp is pressed. The lotus root pulp obtained by pressing is combined with the previously separated lotus root pulp; the lotus root pulp is heated and added...

Embodiment 2

[0023] Take fresh lotus roots with pure taste, no peculiar smell, no pests, and no rot, and the end lotus roots shall not exceed 20%. Rinse the lotus root with water, cut off the lotus root joints, and then scrub the lotus root in clean water until the surface of the lotus root is rust-free, and then put it in a 0.2% citric acid solution for cleaning; send the cleaned lotus root to the crusher for crushing. Add purified water according to the mass ratio of lotus root: purified water at 1:0.9, and then use colloid milling to obtain crude lotus root pulp. While rubber milling, add citric acid to the crude lotus root pulp. Citric acid is added at 0.07% of the washed lotus root mass The crude lotus pulp after rubber milling is used to separate lotus root pulp and lotus root pulp with a continuous separator, and then the lotus root pulp is squeezed, and the lotus root pulp obtained by pressing is combined with the lotus pulp obtained by the separator. Heat the lotus root pulp, add a...

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 of a PET bottled clarified lotus root juice series beverage, which belongs to the technical field of food processing. Background technique [0002] Lotus root (Nelumbo nucifera Gaertn) is a perennial aquatic plant in the Nymphaeaceae family. The lotus root is rich in nutrition. According to the measurement, every 100g lotus root contains 10-20g starch, 1-2g protein, 25-55mg 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 the Chinese people. In recent years, with the development of the food industry, research on lotus root processing has gradually increased. Lotus root juice beverages are popular with consumers for their convenient eating and novel forms. Domestic researchers have conducted a lot of research on lotus root juice beverage processing, mainly focusing on lotus root juice extraction, color protect...
