Embodiment 1

[0032] The selenium-enriched adding machine is applied in the preparation process of instant yam slices, and the process includes the following steps:

[0033] S1: One-time pretreatment: Peel the fresh yam and cut it into sections, put it in a pot, add water to boil until it boils, after 4 minutes, take it out and rinse it with cold water, rinse the viscous liquid on the surface of the yam, and then put the rinsed yam Chinese yam cut into slices with a thickness of 1.5cm, set aside;

[0034] S2: Secondary pretreatment: put the yam slices into the immersion liquid, soak for 30 minutes under the conditions of ultrasonic power of 30W and temperature of 43°C, and then filter; the ratio of the weight of the yam slices to the volume of the immersion liquid is 1:2;

[0035] The soaking liquid is in parts by weight and includes the following raw materials: 0.1 part of fatty acid sucrose ester, 0.3 part of glyceryl monostearate, 0.51 part of D-mannitol, 0.4 part of tripotassium phospha...

Embodiment 2

[0043] The selenium-enriched adding machine is applied in the preparation process of instant yam slices, and the process includes the following steps:

[0044] S1: One-time pretreatment: Peel the fresh yam and cut it into sections, put it in a pot, add water to boil until it boils, after 4 minutes, take it out and rinse it with cold water, rinse the viscous liquid on the surface of the yam, and then put the rinsed yam Chinese yam cut into slices with a thickness of 2cm, set aside;

[0045] S2: Secondary pretreatment: put the Chinese yam slices in step S1 into the immersion liquid, soak them for 35 minutes under the condition of ultrasonic power of 40W and temperature of 45°C, and then filter; the ratio of the weight of the Chinese yam slices to the volume of the immersion liquid is 1:2.5;

[0046] The soaking solution is in parts by weight and includes the following raw materials: 0.2 parts of fatty acid sucrose esters, 0.45 parts of glyceryl monostearate, 0.7 parts of D-mann...

Embodiment 3

[0054] The selenium-enriched adding machine is applied in the preparation process of instant yam slices, and the process includes the following steps:

[0055] S1: One-time pretreatment: Peel the fresh yam and cut it into sections, put it in a pot, add water to boil until it boils, after 4 minutes, take it out and rinse it with cold water, rinse the viscous liquid on the surface of the yam, and then put the rinsed yam Chinese yam cut into slices with a thickness of 2.5cm, set aside;

[0056] S2: Secondary pretreatment: put the yam slices into the immersion liquid, soak for 30 minutes under the conditions of ultrasonic power of 50W and temperature of 48°C, and then filter; the ratio of the weight of the yam slices to the volume of the immersion liquid is 1:3;

[0057] The soaking solution is in parts by weight and includes the following raw materials: 0.3 parts of fatty acid sucrose ester, 0.6 part of glyceryl monostearate, 1 part of D-mannitol, 1.2 parts of tripotassium phosph...

Abstract

The invention discloses a selenium-enriched additive and an application thereof in preparation of ready-to-eat rhizoma dioscoreae slices. The additive is prepared from the following raw materials in parts by weight: sucrose, table salt, seaweed polysaccharide selenide, L-Se-methyl selenocysteine, selenium yeast, konjac fine flour, selenium, zinc and iron; when the selenium-enriched additive is applied to preparation of the ready-to-eat rhizoma dioscoreae slices, sensory index and physical and chemical indexes of the prepared ready-to-eat rhizoma dioscoreae slices are better than those of rhizoma dioscoreae slices prepared in the prior art. Besides, the prepared rhizoma dioscoreae slices are quite high in selenium content and have effects of resisting oxidation, preventing ageing, removing toxin and eliminating toxin, and harm of radiation to human bodies can be reduced to the greatest extent because selenium has the function of protecting the hemopoietic system.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a selenium-enriched additive and its application in preparing instant yam slices. Background technique [0002] Selenium is an essential trace mineral element for the human body, and is closely related to human immune function, anti-oxidation, and anti-cancer effects. Appropriately increasing the intake of selenium is of great significance for maintaining health and preventing the occurrence of certain diseases. Low dietary selenium intake is a potential threat to human health, and selenium in natural foods alone is not enough to meet the normal needs of the human body. Therefore, nutrition experts suggest that selenium-rich foods should be vigorously developed to meet people's health needs. At present, inorganic selenium salts are generally used as fortifiers at home and abroad to supplement the lack of selenium in the diet; studies have shown that the toxicity of organ...
