Abstract

The invention relates to a fresh-keeping method for lotus root, and especially relates to a fresh-keeping method for performing fresh-keeping processing on fresh-cut lotus root slices by using a composite fresh-keeping agent prepared from multiple reagents. The method comprises: selecting onion, squeezing juice, mixing with phytic acid, disodium ethylene diamine tetraacetate, ascorbic acid, L-cysteine and the like, adjusting pH value with citric acid to obtain the composite fresh-keeping agent; immersing the pre-processed lotus root slices in the composite fresh-keeping agent for fresh-keeping processing; and finally employing vacuum package, and placing at appropriate conditions for refrigeration. Due to the fact that the composite fresh-keeping agent prepared from the multiple reagents is utilized as the fresh-keeping agent of the fresh-cut lotus root slices, the fresh-keeping effect is good, and the fresh-keeping period reaches five months or more, so that the problems such as browning, hardness reducing, weight decreasing and the like during storage of the fresh lotus root slices are solved. Additionally, the fresh-keeping method has the advantages of being simple in processing, low in cost, green, environment-friendly, convenient and the like.

Description

technical field

[0001] The invention relates to a fresh-keeping method for fresh-cut lotus root slices, in particular to a fresh-cut fresh-cut lotus root slice fresh-keeping method using a composite preservative made by various reagents for fresh-keeping treatment. Background technique

[0002] People's life rhythm is getting faster and faster, and the quality of life is also getting higher and higher. Clean vegetable processing is bound to become a trend in the current development of vegetable processing, which can meet people's fast-paced life and ensure the quality of life.

[0003] The main measure to prevent the browning of lotus root slices in the production and processing process is to take color protection methods in the processing process. Method 1: Add vitamin C, vitamin C can consume the oxygen needed for browning and maintain the original quality of lotus root. Method 2: Lower the pH value, add citric acid and salt to the color protection solution, and avoid the...

Examples

Embodiment 1

[0025] Embodiment 1: a kind of preservation method of fresh-cut lotus root slices, comprises the following steps:

[0026] (1) Selection of raw lotus root: After purchasing the lotus root, choose fresh lotus root with tender and thick meat, no serious mechanical damage, no pests and diseases, and no browning. Eliminate seriously injured, diseased, too small and too thick lotus roots.

[0027] (2) Cleaning: Wash off the silt and other impurities on the lotus root with water, and clean the lotus root; do not scrub with hard objects (such as straw, woven bags) to prevent scratching the lotus root skin, causing browning and rot.

[0028] (3) Remove joints and skin: After cleaning the lotus root, use a stainless steel knife to cut off the joints and peel off the skin. The requirements for peeling are as follows: the cortex is removed thoroughly, but the lotus root meat must not be damaged too much, and the surface of the lotus root segment after peeling is smooth and clean.
