Description

A device for inactivating plant lectin in wheat germ

technical field

The utility model relates to the field of wheat deep processing, in particular to a device for inactivating plant lectin in grain germs such as wheat germ.

Background technique

Plant lectins were first discovered in 1888. Stillmark discovered a cell agglutination factor in castor bean (Ricinus communis L.) seed extract, which has the effect of agglutinating red blood cells. It is a kind of protein with specific sugar binding activity, which has one or more non-catalytic domains that can specifically and reversibly bind monosaccharides or oligosaccharides. According to the structural characteristics of plant lectin subunits, plant lectins are divided into four types: partial lectins, full lectins, chimeric lectins, and superlectins; according to the homology of amino acid sequences and their evolutionary relationships , plant lectins are divided into seven families: legume lectins, chitin-binding lectins, monocotyledonous mannose-binding lectins, ribosome-inactivating protein type 2, carnelain family, cucurbitaceae phloem lectins, and amaranth Section lectins.

Plant lectins can recognize and bind to the sugar domain of the invader, thereby interfering with the possible impact of the invader on the plant; the sugar-binding activity of the plant lectin is aimed at exogenous oligosaccharides and participates in the defense response of the plant. Many lectins can bind to monosaccharides such as Glc, Man or Gal, and especially have a higher affinity for oligosaccharides that are not commonly found in plants and are foreign. For example: binding chitin lectins to recognize carbohydrates in the cell walls of fungi and exoskeleton components of invertebrates. In addition, many lectins are stable in the higher pH range, resistant to heat, animal and insect proteases, etc. Some lectins are even completely stable proteins. For example, the lectins isolated from the stems of acanthus are stable in trichloroacetic acid and will not be inactivated by boiling. Peumans et al. (1998) believed that most lectins exist in storage organs, and they may function as a nitrogen source or as a defense protein when plants are damaged. Therefore, lectins are an important part of the plant defense system and play an important role in plant protection.

Phytohemagglutinin is the most abundant anti-nutritional substance in wheat germ, which can cause immune system-related diseases in eaters. Inactivating phytohemagglutinin in wheat germ is a key step in the production of healthy wheat germ food. At present, the main methods commonly used to inactivate plant lectins include dry heat, damp heat, acid-base soaking, and adding enzyme preparations. Dry heat inactivation takes a long time and the efficiency is not high. Excessively high temperature will also produce burnt smell and browning, which will damage the nutritional value and functional properties of wheat germ protein; acid-base soaking treatment and adding enzyme preparations will cause chemical residues , and will degrade other nutrients in wheat germ at the same time; moist heat treatment can inactivate lectin under relatively mild conditions, and at the same time, the solubility and quality of wheat germ protein can be preserved to the greatest extent.

Therefore, it is an urgent problem to study a relatively simple and effective way of inactivating lectins to improve the efficiency of the pretreatment process of edible wheat germ and improve the health quality of wheat germ food.
