Problems solved by technology

[0004] Ripe gardenia fruit contains 18-25% oil. In the context of the serious lack of edible oil resources in China, the extraction of oil from gardenia has attracted the attention of the industry, so it will produce 75-80% defatted gardenia Gardenia seed meal, the comprehensive development and utilization of this part of gardenia meal has not received corresponding attention

Embodiment 1

[0015] Embodiment 1, the preparation of the gardenia rice that is rich in geniposide and saffron

[0016] Select 200g of gardenia raw materials into a closed degreasing tank, vacuumize, inject subcritical butane degreasing solvent to completely immerse the sample, the material-solvent ratio is 1:10, the temperature is 25°C, and the time is 30min, and the degreasing is carried out twice. After the degreasing is completed, the gardenia meal is subjected to low vacuum and high vacuum desolventization respectively to obtain the desolventized gardenia meal. Take 20g of the above-mentioned gardenia meal (residual oil rate ≤ 0.1%) as the golden companion of rice, grind it and pass through a 200-mesh sieve, mix it with 400g of rice and an appropriate amount of water, put it into an electric cooker and cook until cooked. After steaming the rice, you can get golden rice. The control is the rice without Golden Companion, and the other operations are the same. After steaming the rice, t...

Embodiment 2

[0017] Embodiment 2, the preparation of the gardenia rice that is rich in geniposide and saffron

[0018] Select 240g of water gardenia raw materials into a closed degreasing tank, vacuumize, inject subcritical propane degreasing solvent to completely immerse the sample, the material-solvent ratio is 1:12, the temperature is 20°C, and the time is 25min, and the degreasing is carried out three times. After the degreasing is completed, the gardenia meal is subjected to low vacuum and high vacuum desolventization respectively to obtain the desolventized gardenia meal. Take 15g of the above-mentioned gardenia meal (residual oil rate≤0.1%) as the rice golden companion. Other operations are the same as above. After steaming the rice, you can get golden rice. The control is the rice without Golden Companion, and the other operations are the same. After steaming the rice, it was found through sensory evaluation that the taste and aroma of the rice added with Golden Companion did no...

Abstract

The invention discloses a preparation method of a rice mate rich in crocin and geniposide, particularly relates to a preparation method of a rice mate rich in crocin and geniposide by utilization of a subcritical extraction technology, and belongs to the field of medicinal food and healthcare food. The preparation method includes three steps, namely, degreasing, desolventizing and cooking. More than 99.9% of liposoluble constituents in materials can be extracted by the subcritical extraction technology (with the oil content of dregs after the degreasing step being lower than 0.1%). The product can be directly used or be further processed as a golden rice mate to prepare jasmine golden rice, and the like. In addition, the biological activity of functional components in the extract is guaranteed and the product is liable to store. Effective components which are the crocin and the geniposide are preserved in the dregs can be further widely applied. Comprehensive utilization of nutritions in the "dregs" after fat is extracted is guaranteed. The method has a wide application scope.

Description

technical field [0001] The invention relates to a preparation method of golden rice mate rich in saffron and geniposide, which belongs to the field of medicinal food and health food. technical background [0002] Rubiaceae gardenia (Gardenia jasminoides Ellis) is one of the first batch of medicinal and edible resources announced by the country. It has the effect of clearing heart, purging fire and eliminating troubles. . With the continuous improvement of living standards and quality at home and abroad, people pay more and more attention to the development and utilization of natural medicinal substances. In recent years, crocin components (known as gardenia yellow) have also been found in gardenia, a commonly used traditional Chinese medicine in China, so the extraction of rare crocin from gardenia has become a research hotspot. The active ingredients of Gardenia mainly include iridoids such as geniposide and oxygen-containing carotenoids such as gardenia yellow (one of th...
