Embodiment 1

[0029] A kind of tomato preserves, its preparation method specifically comprises the following steps:

[0030] 1) Material selection and cleaning: choose 3.64kg of fresh cherry tomatoes that are free from diseases and insect pests, seven to eight mature, and wash them with clean water;

[0031] 2) Microwave killing: remove the stalks from the cleaned cherry tomatoes, and kill them in a microwave environment of 360W for 30s;

[0032] 3) Puncture: Puncture the cherry tomatoes evenly with a punching machine with a needle specification of 2mm; each cherry tomato has 10 holes;

[0033] 4) Hardening: use 0.3kg of δ-gluconolactone to prepare a δ-gluconolactone solution with a mass fraction of 4.5%; soak the punctured cherry tomatoes in the δ-gluconolactone solution for 3 hours ;

[0034] 5) The first solar-heat pump combined drying: Drain the hardened cherry tomatoes, and use solar-heat pump combined drying technology to dry at 45°C for 6 hours until the moisture content of the che...

Abstract

The invention discloses candied cherry tomatoes and a preparation method thereof. Cherry tomatoes, soybean oligosaccharides, xylo-oligosaccharide, white granulated sugar, glucono-delta-lactone, carboxymethyl cellulose sodium, citric acid, and potassium sorbate are used as the raw materials and subjected to the steps including: selecting of raw materials, cleaning, micro-wave water-removing, perforating, hardening, first solar energy-heat pump combined drying, micro-wave sugar permeability, secondary solar energy-heat pump combined drying, micro-wave sterilizing and vacuum packaging, and finally the candied cherry tomatoes which are round in shape, red and bright in color and fresh and sweet in taste are produced. The nutrients of the prepared candied cherry tomatoes are well maintained, and the candied cherry tomatoes have health-care efficacies of regulating the intestinal flora, promoting the growth of bifidobacterium, regulating immunity and preventing decayed tooth. Moreover, the preparation process is simple, and high in operability, and the solar energy-heat pump combined drying technology is adopted, so as to greatly shorten the production time and provide an energy-saving and environmental-protection path for deep processing of cherry tomatoes.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a cherry tomato preserve and a preparation method thereof. Background technique [0002] Candied fruit, also known as preserved fruit, refers to the leisure food made from fresh fruits and vegetables through cleaning, peeling, pitting, boiling in sugar water, drying and other main processes. It is a traditional food in my country and has a broad market at home and abroad. Favored by consumers. Cherry tomatoes belong to the Solanaceae family and the genus Tomato. They are also called fruit tomatoes or cherry tomatoes. Most of them are heart-shaped, crystal clear and nutritious. The candied cherry tomatoes produced by traditional crafts are mostly high-sugar products in order to prolong the shelf life, which is inconsistent with the healthy life philosophy of modern consumers. Therefore, improving the traditional production process of high-sugar preserved fruits...
