Skin prick tests and in vitro immunoassays with native spices and spice extracts.

BACKGROUND: Skin prick tests of native spices (commercial powdered spices) are common in patients with allergy to birch or mugwort pollen. Clinical symptoms from spices are infrequent but occasionally severe. OBJECTIVE: To compare the skin prick test results with native spices and spice extracts and to determine the clinical relevance of test material. METHODS: Skin prick tests with the native spices coriander, caraway, paprika, cayenne, mustard, and white pepper were made twice at 2-month to 2.9-year intervals in 49 patients. During the latter time, tests were also made with spice extracts and spice-specific serum IgE was measured. RESULTS: The reproducibility of skin test results with native spices was 67% to 100%. Spice extracts, except white pepper, elicited positive skin test reactions in half those with positive reactions to native spices. Higher specific IgE concentrations (> or = 3.5 PRU/mL) were seen in cases where the skin tests were positive to the corresponding spices with 5% extracts of > 8 kD Mw. Three-fourths of the patients with positive skin tests to native spices were positive to birch pollen and one-half to a vegetable. Mild clinical symptoms from spices were reported by one-third. CONCLUSIONS: Spice allergens partly crossreact with those of pollens and vegetables. A minority of spice allergens may give clinical symptoms. The > 8-kD 5% extracts may be relevant skin prick test materials for identifying patients at risk of developing severe symptoms from ingested spices.

Spice allergy: results of skin prick tests and RAST with spice extracts.

Skin prick tests (SPT) with freeze-dried spices and 5% (w/v) spice extracts were performed on 50 patients with 2+ or stronger SPT reactions to spices per se, and RAST were performed on 10 of them. Freeze-dried extracts produced mostly equal or stronger SPT reactions than corresponding whole spices, but 5% (w/v) extracts produced weaker reactions and also remained totally negative in some patients. Positive RAST results were seen in all 10 patients tested. The correlation between the RAST and SPT results was good for mustard and paprika, but poor for cayenne, coriander, caraway and white pepper. Five patients with positive SPT and RAST for spices contracted rhinitis from powdered spices in their working environments, and one patient suffered from gastrointestinal pains caused by spiced food. The others had noticed no clinical symptoms caused by spices. The present results thus indicate that both SPT and RAST should include purified spice extracts.

Influence of spices and spice principles on hepatic mixed function oxygenase system in rats.

The status of hepatic mixed function oxygenase system (MFOS) was investigated in rats fed spice principles: capsaicin, piperine and curcumin, as well as spices: cumin, ginger, fenugreek, cinnamon, asafoetida, mustard and tamarind at two dietary levels each. Liver microsomal cytochrome P450-dependent aryl hydroxylase was generally stimulated by these spice principles and spices. Cumin, ginger and fenugreek also stimulated the levels of cytochrome P450 and cytochrome b5 and cumin and tamarind stimulated N-demethylase activity. NADPH-cytochrome c reductase and glucuronyl transferase activities, however, remained unaffected by the spices tested.

[So-called "celery-carrot-mugwort-spice syndrome." RAST results with new spice discs].

RAST investigations on the sera of 27 patients suffering from celery allergy showed specific IgE to mugwort and birch in 15 cases; sensitization to mugwort or birch alone only occurred in 5 and 7 cases, respectively. Positive RAST results were also obtained with several spices. We found a relationship between spice and celery allergy.

Insulin potentiating factor and chromium content of selected foods and spices.

An unidentified factor that potentiates the action of insulin in glucose metabolism was investigated in selected foods and spices. Chromium content of these foods and spices was also determined. Foods and spices were extracted with 0.1N NH4OH (1:20, w/v) and the supernatants assayed for insulin potentiation activity in the rat epididymal fat cell assay. Among the selected foods, tuna fish, peanut butter, and vanilla ice cream had some insulin potentiating activity. Among the spices, apple pie spice, cinnamon, cloves, bay leaves, and turmeric potentiated insulin activity more than three-fold. Chromium concentration of foods ranged from 1 to 145 ng/g, and spices ranged from 4 to 1818 ng/g. Insulin potentiating activity of foods and spices did not correlate with total chromium. Spices are generally used for flavor and taste in food preparations, but cinnamon, cloves, bay leaves, and turmeric may have an additional role in glucose metabolism.

Common Indian spices: nutrient composition, consumption and contribution to dietary value.

Nutrient composition of eight commonly consumed spices of South India was analysed. Spices analysed were red chillies (Capsicum annum), black pepper (Piper nigrum), coriander seeds (Coriandrum sativum), cumin seeds (Cuminum cyminum), garlic (Allium sativum), asafoetida (Ferula foetida), dry ginger (Zingiber officinale) and ajowan (Carum copticum). The nutrients analysed were proximate principles, minerals, starch, sugars, dietary fibre components, tannins, phytic acid, enzyme inhibitors and amino acids. Dry ginger, ajowan and asafoetida had high calcium (1.0-1.5%) and iron (54-62 mg/100 g) levels. The tannin content of spices was also high (0.9-1.3% DM). Dietary fibre ranged from 14-53%. Spices had appreciable amounts of essential amino acids like lysine and threonine. A survey revealed the average per capita consumption of spices to be 9.54 g and at that level, the nutrient contribution from spices ranged from 1.2 to 7.9% of an average adult Indian male's requirement for different nutrients.

Effect of irradiation on the microbiological status and flavouring materials of selected spices.

Spices from Egyptian local markets were irradiated with different recommended doses (0, 5, 10, 20 and 30 kGy). The spices tested included dried leaves of marjoram (Majorana hortensis Moench), rhizomes of ginger (Zingiber officinale Roscoe) and powdered hot pepper (Capsicum annum L.). The study included the isolation and identification of micro-organisms in spices following their irradiation, as well as gas chromatographic (GLC) chemical analysis for the presence and structure of volatile oils, pungent and pigment materials. The results showed that hot pepper was contaminated more (9.2 x 10(5)/g) than marjoram (4.2 x 10(3)/g) and ginger (14.3 x 10(3)/g) with respect to total aerobic bacterial content. The total contents of moulds were 4.8 x 10(3)/g, 5.7 x 10(3)/g and 19 x 10(3)/g in the same spices, respectively, but the pathogenic moulds and bacterial strains differed according to the type of spice. Irradiation at 10, 20 and 30 kGy caused complete elimination of micro-organisms, whereas 5 kGy was less effective. With the GLC method chosen 18 and 50 compounds could be detected in the extracts of marjoram and ginger, respectively; gamma-terpinen and zingiberen being the major compounds in marjoram and ginger, respectively. A noticeable reduction was observed in the amount of terpenes present in irradiated marjoram; they were converted to monoterpenesalcohols. Ginger was more sensitive to irradiation, especially at high doses, but moderate changes were detected at low doses (5 and 10 kGy). A slight, but significant effect on the capsaicin (pungent compound) in hot-pepper was observed following irradiation, whereas no changes in total pigments resulted at any dose. These results prove that 10 kGy is a sufficiently high dose to eliminate the micro-organisms in spices, causing only slight changes in the flavouring materials.

Occupational allergic contact dermatitis from spices.

About 1000 patients were investigated at our clinic during 1991-1995 for occupational skin disease, and 5 had occupational allergic contact dermatitis from spices. The patients were chefs, or kitchen, coffee room, and restaurant workers. All patients had hand (or finger) dermatitis. The causative spices were: garlic, cinnamon, ginger, allspice and clove. The same patients also had allergic patch test reactions to foods: tomato, lettuce and carrot. Paprika elicited a weak allergic patch test reaction in 2 patients. Occupational allergic contact dermatitis from spices is relatively rare, but needs to be taken into consideration in patients who have hand dermatitis, and work with spices and foods. Patch testing with spices as is is useful, but testing with dilutions in pet, may be needed to confirm that the patch test reactions are allergic. Patients also need to be prick tested with spices and foods.

Immunological and respiratory findings in spice-factory workers.

Immunological and respiratory findings were studied in a group of 45 female spice-factory workers (mean age: 39 years; mean exposure: 17 years). In addition a group of 45 female control workers matched by sex, age, and smoking habit were also studied. Intradermal skin testing with mixed spice dust allergen demonstrated positive skin reactions in 73.3% of exposed and in 33.3% of control workers (P less than 0.001). Increased IgE serum levels were found in 36.8% of exposed and in 9.7% of the control workers (P less than 0.01). The prevalence of chronic respiratory symptoms was significantly higher in the exposed workers than in the control workers (P less than 0.01). There was, however, no consistent correlation between skin reactivity and chronic respiratory symptoms. There was a high prevalence of acute symptoms during the work shift. These complaints were more frequent in workers with positive skin tests for the symptoms of cough, chest tightness, and irritated and dry throat. Ventilatory capacity was measured by recording maximum expiratory flow-volume (MEFV) curves. There were statistically significant mean reductions during the work shift for all measured lung function parameters in workers with positive skin reactions. In those workers with negative skin reactions only FEF50 and FEF25 reached statistical significance. Aqueous extracts of different spices (chilli pepper, paprika, caraway, coriander leaves, coriander seeds, cinnamon, ginger, onion, curry, and parsley) caused a dose-related contractile response of isolated guinea pig tracheal smooth muscle. These data suggest that immunologic reactions to spices are frequent in spice workers and may be related to acute symptoms and lung function changes, but not to chronic changes. The data further suggest that, in addition to any immunologic response these spices may produce in vivo, they probably also provoke direct irritant reactions in the airways as suggested by in vitro data.

Delayed-type allergy to spices.

9 common spices were tested epicutaneously in 338 dermatological patients, 118 of whom were allergic to balsam of Peru. Positive reactions to one or more spices were seen in 50 patients all of whom except 2 were allergic to balsam of Peru. The spices giving positive reactions most often were clove, Jamaica pepper and cinnamon (cassia). 2/3 of the patients allergic to balsam of Peru or spices were women, usually suffering from hand eczema. Peroral challenge with spices was carried out in 71 patients allergic to balsam of Peru. Pompholyx on the palms and other objective symptoms were encountered in 7 cases, 3 of whom showed no reactions to spices in epicutaneous tests.

Chemical composition of indigenous wild herbs, spices, fruits, nuts and leafy vegetables used as food.

Thirty wild fruits, nuts, herbs, spices and leafy vegetables were characterized and their chemical composition determined. Some of them were not only used for food, but for medicine in minor aliments by the natives. Results of the proximate analysis showed that on dry weight basis, the crude protein content ranged from 4.6 to 22.1 percent for spices and herbs, 3.2 to 43.1 percent for fruits and nuts, and 15.9 to 35.7 percent for leafy vegetables. The fat (ether extract) ranged from 7.5 to 36.0 percent for spices and herbs, 1.8 to 72.6 percent for fruits and nuts and 10.6 to 22.6 percent for leafy vegetables. Total carbohydrate content ranged from 34.6 to 71.9 percent for spices and herbs, 11.3 to 76.1 percent for fruits and nuts, and 24.6 to 51.4 percent for leafy vegetables. The wild fruits, nuts and leafy vegetables are high in ascorbic acid (Vitamin C.) Ascorbic acid content ranged from 18 mg/100 g dry sample to 113 mg/100 g sample for fruits and nuts, and 23 mg/100 g to 232 mg/100 g sample for leafy vegetables. The levels for peroxide value and free fatty acids (as percent oleic acid) of the spices are generally low indicating good storage stability of these plant materials. The flavour imparting essential oils (as percent oleoresin) content of the spices/herbs were fairly high and ranged from 0.1 to 5.2 percent.

Effect of Laser trilobum spice on natural microflora of köfte, a Turkish ground meat product.

The effect of Laser trilobum spice on natural microflora of "köfte", a Turkish ground meat product, prepared using three beef samples and stored at 7 degrees C and 20 degrees C was evaluated. Little or no inhibition was seen in all products and temperatures with 1.0% spice. Growth of natural microflora, namely total viables, coliforms, psychrotrophs and yeasts-moulds, was significantly inhibited by 2.0% of the spice, especially at 7 degrees C. The inhibitory effect of the spice increased with decreased fat content and increased water and protein contents of beef samples. It was concluded that the usual addition of the spice improved the hygienic quality of the product containing low fat and stored at 7 degrees C.

Influence of spices on utilization of sorghum and chickpea protein.

Influence of eight common Indian spices on the protein quality of sorghum and chickpea was studied. Spices used include red chillies (Capsicum annum), black pepper (piper nigrum), coriander seeds (Coriandrum sativum) cumin seeds (Cuminum cyminum), garlic (Allium sativum), asafoetida (Ferula foetida), dry ginger (Zingiber officinale) and ajowan (Carum copticum). Addition of spices did not affect protein digestibility (TD) of sorghum. The BV of all sorghum diets with spices was higher than that of control diet. However, it was significant only in case of diets combined with red chilli + coriander (1:1) mix, black pepper + cumin (1:1) mix, coriander and cumin. Addition of spices did not have any effect on TD or BV of chickpea diets.
