Embodiment 1

[0022] 1. Take 5 kg of mature fresh lotus with shell (the surface of the shell is light brown or brown) and peel off the shell manually or mechanically to obtain fresh lotus weighing about 3.3 kg.

[0023] 2. In a 10L stainless steel barrel, use the sodium carbonate of edible alkalis in food additives according to the ratio of 1:1 between the weight of the solution and the weight of fresh lotus after shelling, and prepare a peeling solution with a concentration of 3.0% and a temperature of 65°C. .

[0024] 3. Pour the peeled fresh lotus into the above-mentioned prepared sodium carbonate peeling solution, and cover the liquid with a glass cover to prevent the fresh lotus from contacting with air. At the same time, put the stainless steel barrel into a large plastic barrel filled with hot water at about 65°C to keep warm (the water level is higher than the liquid level in the stainless steel barrel), so that the temperature of the peeling solution after feeding is kept within th...

Embodiment 2

[0028] Similar to Example 1, the difference is that the concentration of the prepared sodium carbonate peeling solution is 2.5%, the temperature of the solution after feeding is controlled within the range of 53-55° C., and the treatment time is 8 minutes. The peeling rate of fresh lotus can reach more than 90% by adopting the process; the sensory quality of the finished product is close to that of the traditional manual peeling method (a few particles have skin tips).

Embodiment 3

[0030] Similar to Example 1, the difference is that the concentration of the prepared sodium carbonate peeling solution is 3.5%, the temperature of the solution after feeding is controlled within the range of 50-53° C., and the treatment time is 6 minutes. The peeling rate of fresh lotus can reach 100% by adopting the process; the sensory quality of the product is basically close to that of the traditional manual peeling method (the color of some particles is yellowish).

Abstract

The invention provides a peeling method for fresh lotus roots, which applies either sodium carbonate of the edible alkali or a mixture of sodium carbonate and potassium carbonate in the food additives as a peeling reagent for the fresh lotus roots. The peeling method for fresh lotus roots adopts the technical proposal that: peeling solutions are prepared, with a concentration between 1.5 and 4.0 percents and a temperature less than 70 DEG centigrade through sodium carbonate or the mixture of sodium carbonate and potassium carbonate first; the mature and fresh lotus roots are soaked into the solution after removing shells thereof; the temperature of the solutions is controlled between 45 and 60 DEG centigrade after the mature and fresh lotus roots are put into the solutions; a 5 to 10-minute treatment is conducted under the condition of oxygen isolation and heat insulation in the temperature between 45 and 60, and stirrings are carried out every two minutes; the fresh lotus roots are immediately fetched after the soaking treatment; the skins of the lotus roots are manually rubbed out via flowing water, with a peeling rate between 80 and 100 percents. The peeling method for fresh lotus roots has the advantages of solving the problems of low productivity in the existing peeling method for fresh lotus roots, safety and high efficiency, convenience and practicality, high speed, and low cost, and is suitable for large-scale productions.

Description

technical field [0001] The invention belongs to the field of food processing, and more specifically relates to a fresh lotus peeling method. Background technique [0002] At present, most of the Tongxin Bailian products produced in the lotus seed producing areas sold in the domestic market are treated with the most primitive manual peeling (filming) method of peeling (filming) the fresh lotus in the process of processing. . For example, the article "Jianning White Lotus Processing Technology" in the third issue of "China Agricultural Technology Promotion" in 2002, "Fujian Province Local Standards" (DB35 / T47.4-2001, DB35 / T47.4-2007) "Jianlian Standard Comprehensive The article "Technical Specifications for Processing Lotus Lotus" in "Jianlian Body" and the article "National Standard of the People's Republic of China" (GB / T20356-2006) "Geographical Indication Product Guangchang White Lotus" respectively introduce the traditional manual peeling (membrane) of fresh lotus.
